Definitions
- the invention belongs to the field of biological/medical waste treatment and recycling, and particularly relates to a multi-stage processing method and equipment for biomedical waste and a recycling method after treatment.
- Biomedical waste (BMW) consists of solids, liquids, sharps, and laboratory waste. They are potentially infectious and dangerous, such as bacteria, viruses, and other microorganisms. Biomedical waste must be properly disposed of to protect public health and to protect groups of medical and health workers who need frequent exposure to biomedical waste for work reasons.
- Biomedical waste is one of the most difficult to treat in heterogeneous waste because it contains pathogenic microorganisms, is mixed with a wide variety of materials, and is not allowed to be sorted by law. Handling non-homogeneous waste without sorting is a difficult, costly and long-standing issue.
- Biomedical waste must be sterilized prior to any recycling. Special equipment is required to achieve the required microbial killing effects, such as various bacteria, viruses, fungi and bacterial spores. However, for recycling purposes, all waste needs to be thoroughly sterilized before being exposed to the environment and to the population. In addition, in order to meet the regulatory requirements for the treatment of biomedical waste into an “unrecognizable” state, and to expose the waste to the thermal and chemical disinfection media as fully as possible, it is necessary to pulverize the biological waste in advance. For recycling, this process is very important because people are afraid of products made from recycled materials from medical waste. In order to protect the public and health care workers, health workers and other people who are frequently exposed to the occupational hazards of biomedical waste, BMW must be properly managed.
- STAATT-III takes into account the limitations of available biomedical waste disinfection techniques and specifies that the killing efficiency for viruses, bacteria and fungal spores is divided into six orders of magnitude.
- STAATT-III takes into account the limitations of available biomedical waste disinfection techniques and specifies that the killing efficiency for viruses, bacteria and fungal spores is divided into six orders of magnitude.
- more and more countries have turned the disinfection standard for medical waste into “complete disinfection”, which is not possible with the treatment technology of existing chemical disinfectants, mainly due to the existing chemical disinfection technology. Basic restrictions.
- the biomedical waste treatment methods currently used are mainly divided into three categories: incineration, thermal disinfection and chemical disinfection.
- the incineration method treats biomedical waste directly through high-temperature incineration. This method is more thorough, but it produces toxic gases such as dioxins, which pollutes the air and the environment, and consumes more energy.
- Common thermal disinfection techniques generally It is steam sterilization, that is, steam is introduced under high pressure to heat the waste to 121-140 ° C; steam sterilization is a simple and effective method to treat biological waste, but it consumes a lot of energy and disinfects the enclosed space in the garbage. It may not be effective, and there are significant limitations to crushing the trash after heating; in addition, steam sterilization usually produces an unpleasant odor.
- thermal disinfection techniques include dry heat sterilization, which also produces toxic gases such as dioxins and high energy consumption.
- these techniques are not particularly satisfactory, as these methods generally leave a pungent odor, blood, bacterial growth media, and even body tissue. Residues of these organic components can cause the re-growth of pathogenic microorganisms after treatment, and the waste will become unstable during recycling and reuse. The organic components will continue to degrade.
- Glutaraldehyde is used as a chemostat culture rather than a disinfectant; the disinfection effect of quaternary amines does not meet regulatory requirements.
- Disinfectants using quaternary amines combined with glutaraldehyde, such as SteriCid and ViroCid, provide only 2-3 orders of magnitude of bacterial disinfection efficiency and do not meet STAATT requirements, which is considered an international standard for disinfection efficiency. .
- volatile vapors of glutaraldehyde and hypochlorous acid are toxic, and carcinogens are easily formed when reacted with oxygen.
- the low concentration of hydrogen peroxide solution is very low in disinfection efficiency and can only provide 3-4 orders of magnitude disinfection.
- the method of reacting hydrogen peroxide with acetic acid with or without a catalyst to increase the disinfecting effect of hydrogen peroxide has been intensively studied and even patented.
- the active substance peracetic acid is formed, which is the disinfecting products Kickstart and Kenocid produced by the Belgian company CidLines, which contain peracetic acid, hydrogen peroxide and acetic acid, and may also contain other A component such as sulfuric acid is added as a catalyst for producing peracetic acid.
- Cidlines The disinfection efficiency reported by Cidlines is 2% disinfectant, which can achieve 5 orders of magnitude disinfection efficiency for various bacteria and 2-4 orders of magnitude for fungi and spores. Disinfection efficiency does not meet the STAATT standard.
- China Engineering Journal published an article on the use of sulfuric acid to promote the reaction of hydrogen peroxide with acetic acid to form peracetic acid, entitled “Experiment and Modeling of Peracetic Acid with Hydrogen Peroxide and Acetic Acid” (Zhao Xuebing, Zhang Ting, Zhou Yujie) , Andy Lau. "Preparation of Peracetic Acid from Acetic Acid and Hydrogen Peroxide: Exploration and Modeling.” Chinese Journal of Process Engineering, February 2008, Vol. 8, No. 1, pp.
- Disinfection with high concentrations of disinfectant has never been patented because of the high cost of the disinfectant and environmental impact. Due to the chemical nature of hydrogen peroxide, the use of high concentrations of hydrogen peroxide in open systems is dangerous. High concentrations of hydrogen peroxide react with detergents and surfactants. Disinfection with high concentrations of peroxides while pulverizing is not possible.

Abstract
Description
本发明属于生物/医疗废弃物处理和回收领域,特别涉及一种生物医疗垃圾的多级处理方法和设备以及处理后的回收利用方法。The invention belongs to the field of biological/medical waste treatment and recycling, and particularly relates to a multi-stage processing method and equipment for biomedical waste and a recycling method after treatment.
生物医疗废弃物(BMW)由固体、液体、锐器及实验室垃圾组成,它们具有潜在感染性和危险性,如含有细菌、病毒等微生物。生物医疗垃圾必须妥善处理,以保护公众健康,以及保护由于工作原因而需要频繁接触生物医疗垃圾的医疗与卫生工作者等群体。Biomedical waste (BMW) consists of solids, liquids, sharps, and laboratory waste. They are potentially infectious and dangerous, such as bacteria, viruses, and other microorganisms. Biomedical waste must be properly disposed of to protect public health and to protect groups of medical and health workers who need frequent exposure to biomedical waste for work reasons.
生物医疗废弃物是非均质废弃物中最难处理的一种,因为其含有致病性微生物、混合有各种各样的材料,而且法律不允许对其进行分拣。在不经分拣的情况下处理非均质废弃物是一个高难度,高成本且长期以来无人研究的课题。Biomedical waste is one of the most difficult to treat in heterogeneous waste because it contains pathogenic microorganisms, is mixed with a wide variety of materials, and is not allowed to be sorted by law. Handling non-homogeneous waste without sorting is a difficult, costly and long-standing issue.
生物医疗废弃物在进行任何回收利用前必须进行灭菌。需要采用特殊设备以达到规定要求的微生物杀灭效果,如各种细菌,病毒,真菌和细菌芽孢。然而,为了达到回收利用的目的,所有废弃物在暴露到环境和人群中之前都需要进行彻底的灭菌消毒。此外,为了达到法规要求的将生物医疗废弃物处理成“不可辨识”状态,也为了使废弃物尽可能充分地暴露于热和化学消毒介质中,还需要事先对生物废弃物进行粉碎。对于回收利用来说,这一过程非常重要,因为人们对于使用医疗废弃物回收材料做成的产品怀有恐惧感。为了保护公众和医护工作者、卫生工作者这类经常暴露于生物医疗废弃物的职业危险中的人群,BMW必须进行妥善管理。Biomedical waste must be sterilized prior to any recycling. Special equipment is required to achieve the required microbial killing effects, such as various bacteria, viruses, fungi and bacterial spores. However, for recycling purposes, all waste needs to be thoroughly sterilized before being exposed to the environment and to the population. In addition, in order to meet the regulatory requirements for the treatment of biomedical waste into an “unrecognizable” state, and to expose the waste to the thermal and chemical disinfection media as fully as possible, it is necessary to pulverize the biological waste in advance. For recycling, this process is very important because people are afraid of products made from recycled materials from medical waste. In order to protect the public and health care workers, health workers and other people who are frequently exposed to the occupational hazards of biomedical waste, BMW must be properly managed.
国家及地域性替代处理技术协会(STAATT)制定的《医疗废弃物处理技术国家管理规定》(State Regulatory Oversight of Medical Waste Treatment Technologies)被世界上大部分的监管机构所采用,其中规定了有限的医疗废物的微生物杀灭效率。STAATT-III中考虑了现有可用的生物医疗废弃物消毒技术的限制,规定对于病毒、细菌和真菌孢子的杀灭效率分为6个数量级。然而,越来越多的国家将医疗废弃物的消毒标准变成“完全消毒”,这一要求是使用现有化学消毒液的处理技术所无法实现的,这主要是由于现有的化学消毒技术基础方面的限制。The State Regulatory Oversight of Medical Waste Treatment Technologies, developed by the National and Regional Alternative Treatment Technology Association (STAATT), is used by most of the world's regulatory agencies, which stipulates limited medical care. The microbial killing efficiency of waste. STAATT-III takes into account the limitations of available biomedical waste disinfection techniques and specifies that the killing efficiency for viruses, bacteria and fungal spores is divided into six orders of magnitude. However, more and more countries have turned the disinfection standard for medical waste into “complete disinfection”, which is not possible with the treatment technology of existing chemical disinfectants, mainly due to the existing chemical disinfection technology. Basic restrictions.
目前所使用的生物医疗废弃物处理方法,主要分为三大类:焚烧法、热消毒法和化学消毒法。焚烧法是将生物医疗废弃物直接通过高温焚烧进行处理,这种方法消毒较为彻底,但是会产生二噁英等有毒气体,严重污染空气及环境,而且能耗较高;普通的热消毒技术一般是蒸汽消毒,即在高压下通入蒸汽将废弃物加热到121-140℃;蒸汽消毒是处理生物垃圾的一种简单有效的方法,但需要消耗大量的能量,并且对于垃圾中封闭空间的消毒可能并不有效,在加热之后再粉碎垃圾也有明显的局限性;另外,蒸汽消毒通常会产生难闻的气味。其他的热消毒技术还有干燥热消毒,这种技术同样会产生类如二噁英等有毒气体,且能耗很高。综上所述,这些技术都不是特别符合人们的要求,因为这些方法普遍会留下刺鼻气味、血迹、细菌生长媒介,甚至身体组织。这些有机成分的残留会造成处理后致病性微生物重新生长,也会使废弃物在回收再利用过程中变得不稳定,因为其中 的有机物成分会不断降解。The biomedical waste treatment methods currently used are mainly divided into three categories: incineration, thermal disinfection and chemical disinfection. The incineration method treats biomedical waste directly through high-temperature incineration. This method is more thorough, but it produces toxic gases such as dioxins, which pollutes the air and the environment, and consumes more energy. Common thermal disinfection techniques generally It is steam sterilization, that is, steam is introduced under high pressure to heat the waste to 121-140 ° C; steam sterilization is a simple and effective method to treat biological waste, but it consumes a lot of energy and disinfects the enclosed space in the garbage. It may not be effective, and there are significant limitations to crushing the trash after heating; in addition, steam sterilization usually produces an unpleasant odor. Other thermal disinfection techniques include dry heat sterilization, which also produces toxic gases such as dioxins and high energy consumption. In summary, these techniques are not particularly satisfactory, as these methods generally leave a pungent odor, blood, bacterial growth media, and even body tissue. Residues of these organic components can cause the re-growth of pathogenic microorganisms after treatment, and the waste will become unstable during recycling and reuse. The organic components will continue to degrade.
一般来说,采用化学消毒技术处理生物医疗废弃物的案例很少见,这主要是因为化学消毒的效果有限、消毒液具有潜在毒性、可能排放有毒气体、排放用过的消毒水时可能造成水污染、并且消毒之前需要进行有效粉碎以使废弃物与消毒液充分接触等因素的限制。现有常规的化学消毒液通常有:次氯酸、戊二醛、季胺类物质和过氧化氢。次氯酸并不常用,因为用次氯酸消毒需要较高的浓度和较长的消毒时间,消毒过程中还会产生具有毒性的氯气。戊二醛则被用作恒化培养剂而不是消毒液;季胺类物质的消毒效果达不到法规的要求。使用季胺类物质和戊二醛相结合的消毒液,如SteriCid和ViroCid只能提供2-3个数量级的细菌消毒效率,不能满足STAATT的要求,而该要求被视作是消毒效率的国际标准。另外,戊二醛和次氯酸的挥发蒸汽具有毒性,与氧气反应时易生成致癌物质。In general, the use of chemical disinfection technology to treat biomedical waste is rare, mainly because of the limited effectiveness of chemical disinfection, the potential toxicity of disinfectant, the possibility of emitting toxic gases, and the potential for water when draining used disinfectant. It is necessary to carry out effective pulverization before the disinfection and disinfection to make the waste and the disinfectant fully contact. Conventional conventional chemical disinfectants usually include hypochlorous acid, glutaraldehyde, quaternary amines and hydrogen peroxide. Hypochlorous acid is not commonly used because disinfection with hypochlorous acid requires higher concentrations and longer disinfection times, as well as toxic chlorine in the sterilization process. Glutaraldehyde is used as a chemostat culture rather than a disinfectant; the disinfection effect of quaternary amines does not meet regulatory requirements. Disinfectants using quaternary amines combined with glutaraldehyde, such as SteriCid and ViroCid, provide only 2-3 orders of magnitude of bacterial disinfection efficiency and do not meet STAATT requirements, which is considered an international standard for disinfection efficiency. . In addition, volatile vapors of glutaraldehyde and hypochlorous acid are toxic, and carcinogens are easily formed when reacted with oxygen.
低浓度的过氧化氢溶液用于消毒时消毒效率非常低,仅能提供3-4个数量级的消毒效果。在有/无催化剂的条件下用过氧化氢和醋酸反应以提高过氧化氢的消毒效果的方法已经被深入研究甚至申请了专利。过氧化氢与醋酸反应并有硫酸作为激活剂的情况下会形成活性物质过乙酸,即为比利时公司CidLines生产的消毒产品Kickstart和Kenocid,其中含有过乙酸、过氧化氢和乙酸,还可能含有其他添加成分,如硫酸作为生成过乙酸的催化剂。Cidlines所报告的消毒效率为使用2%的消毒液,对于各种细菌可以达到5个数量级的消毒效率,对于真菌和孢子可以达到2-4个数量级的消毒水平。消毒效率并不能满足STAATT的标准。2008年中国工程期刊上曾发表过关于用硫酸促进过氧化氢和醋酸反应生成过乙酸的文章,题为《用过氧化氢和乙酸制备过乙酸的实验和建模》(赵雪冰,张婷,周玉杰,刘德华.“Preparation of Peracetic Acid from Acetic Acid and Hydrogen Peroxide:Experimentation and Modeling”.过程工程学报,2008年2月,第8卷第1期,第35-41页),其中明确指出了温度对于增强过乙酸消毒效果的作用。另外,较高的温度可以促进过氧化氢分解为水和氧气,在与空气在高温下接触时有可能生成臭氧,这是一种不稳定但强效的消毒液,其在生物医疗废弃物消毒方面的应用已经注册专利(US5087419),并已经被生产和销售(Qzonator NG-3000,Ozonator工业有限公司)。形成臭氧对于灭菌消毒非常有利并且很安全,因为它遇到蒸汽时会降解,因而在高压蒸汽灭菌过程中强效消毒同时自身降解为无害的氧气、所以不在消毒结束时排出造成污染。两个中国专利,CN 101828551和CN 103704264,公开了用过氧化氢和醋酸在硫酸的催化下制取过乙酸的方法,同时也公开了使用过氧化氢-醋酸-硫酸溶液混合洗涤剂和表面活性剂的方法。这些专利公开了使用低浓度的以上溶液,用于家庭、医院和工业,但并没有提到将这种溶液用于医疗废弃物的消毒。并且,安哈尔特应用科学大学2015年的研究结果表明,过氧化氢与戊二醛和/或季铵化合物共同使用具有协同性消毒作用,但会在24小时之内就显著影响消毒液的稳定性,这主要是由于过氧化氢与其他成分的反应。The low concentration of hydrogen peroxide solution is very low in disinfection efficiency and can only provide 3-4 orders of magnitude disinfection. The method of reacting hydrogen peroxide with acetic acid with or without a catalyst to increase the disinfecting effect of hydrogen peroxide has been intensively studied and even patented. When hydrogen peroxide is reacted with acetic acid and sulfuric acid is used as an activator, the active substance peracetic acid is formed, which is the disinfecting products Kickstart and Kenocid produced by the Belgian company CidLines, which contain peracetic acid, hydrogen peroxide and acetic acid, and may also contain other A component such as sulfuric acid is added as a catalyst for producing peracetic acid. The disinfection efficiency reported by Cidlines is 2% disinfectant, which can achieve 5 orders of magnitude disinfection efficiency for various bacteria and 2-4 orders of magnitude for fungi and spores. Disinfection efficiency does not meet the STAATT standard. In 2008, China Engineering Journal published an article on the use of sulfuric acid to promote the reaction of hydrogen peroxide with acetic acid to form peracetic acid, entitled "Experiment and Modeling of Peracetic Acid with Hydrogen Peroxide and Acetic Acid" (Zhao Xuebing, Zhang Ting, Zhou Yujie) , Andy Lau. "Preparation of Peracetic Acid from Acetic Acid and Hydrogen Peroxide: Exploration and Modeling." Chinese Journal of Process Engineering, February 2008, Vol. 8, No. 1, pp. 35-41, which clearly indicates the temperature for enhancement The effect of peracetic acid disinfection. In addition, higher temperatures promote the decomposition of hydrogen peroxide into water and oxygen, which may form ozone when exposed to air at elevated temperatures. This is an unstable but potent disinfectant that is sterilized in biomedical waste. The application has been registered (US5087419) and has been produced and sold (Qzonator NG-3000, Ozonator Industries Ltd.). The formation of ozone is very advantageous and safe for sterilization, because it degrades when it encounters steam, and thus it is strongly disinfected in the high-pressure steam sterilization process while degrading itself into harmless oxygen, so it is not discharged at the end of disinfection. Two Chinese patents, CN 101828551 and CN 103704264, disclose the preparation of peracetic acid by the use of hydrogen peroxide and acetic acid under the catalysis of sulfuric acid, and also disclose the use of hydrogen peroxide-acetic acid-sulfuric acid solution to mix detergents and surface active agents. Method of the agent. These patents disclose the use of low concentrations of the above solutions for use in home, hospital and industry, but do not mention the use of such solutions for the disinfection of medical waste. Moreover, the 2015 results of the Anhalt University of Applied Sciences show that hydrogen peroxide is synergistically disinfected with glutaraldehyde and/or quaternary ammonium compounds, but it significantly affects the disinfectant within 24 hours. Stability, mainly due to the reaction of hydrogen peroxide with other components.
使用高浓度的消毒液进行消毒从未被申请过专利,因为消毒液成本较高且会产生环境影响。由于过氧化氢化学性质活泼,在开放系统中使用高浓度过氧化氢很危险,高浓度过氧化氢会与洗涤剂和表面活性剂产生反应,在粉碎的同时使用高浓度过氧化物消毒是不可行的,而这些物质在消毒过程中又是必须的,并且法规规定生物医疗器械必须在边消毒边粉碎,不能先粉碎再消毒。Disinfection with high concentrations of disinfectant has never been patented because of the high cost of the disinfectant and environmental impact. Due to the chemical nature of hydrogen peroxide, the use of high concentrations of hydrogen peroxide in open systems is dangerous. High concentrations of hydrogen peroxide react with detergents and surfactants. Disinfection with high concentrations of peroxides while pulverizing is not possible. Yes, and these substances are necessary in the disinfection process, and the regulations stipulate that biomedical devices must be comminuted while disinfecting, and can not be pulverized and then sterilized.
而生物医疗废弃物在灭菌消毒之后的回收利用方式,从环境角度来看是一个非常值得关注的问题。医疗废弃物通常具有感染性,现在主要的方式为灭菌后在垃圾填埋场长期降解。尽管医疗废弃 物中许多部分是可以回收利用的,但由于这些物质受到感染源的污染,以及受到人们对医疗废弃物污染的担忧的影响,这些物质并没有得到回收利用。这造成了本可以被回收的价值数十亿美元的材料被浪费,并且占用了宝贵的垃圾填埋空间,The recycling of biomedical waste after sterilization and disinfection is an issue of great concern from an environmental point of view. Medical waste is often infectious, and the main mode now is long-term degradation in landfills after sterilization. Despite medical disuse Many parts of the material are recyclable, but these substances are not recycled because they are contaminated by sources of infection and by concerns about contamination of medical waste. This has resulted in the waste of billions of dollars worth of material that could have been recycled and the use of valuable landfill space.
处理后生物医疗废弃物的回收利用在环保和创造利润层面吸引了广泛的兴趣。该回收工艺过程可用于生物医疗废弃物,以后还有可能扩展到各种非均质废弃物,如生活/市政垃圾。The recycling of biomedical waste after treatment has attracted wide interest in environmental protection and profit creation. The recycling process can be used for biomedical waste and may later be extended to various heterogeneous wastes such as domestic/municipal waste.
废弃物分为可分拣的废弃物和不可分拣的废弃物,现有技术对可分拣的废弃物的回收利用操作复杂,而对不可分拣的废弃物的回收利用就并没有有效方法。Waste is divided into sortable waste and non-sortable waste. The prior art has complicated recycling operations for sortable waste, and there is no effective way to recycle non-sortable waste. .

本发明的作用原理是:本发明公开了一种用于处理生物废弃物(BMW)的方法及设备。本方法及设备可以对BMW进行粉碎、过氧化物消毒和热消毒几种方法的组合和顺序消毒。各种不同种类的消毒液混合会产生协同效应,而顺序消毒过程则可获得高达100%的灭菌效果。BMW在进入本设备后会被粉碎并过氧化物消毒。过氧化物消毒由一种消毒混合制剂完成,是一种具有杀毒性能且不产生有害气体和水污染的消毒溶液,例如过氧化氢可化学分解为氧气和水,或与有机物反应生成二氧化碳和水,或臭氧在蒸汽锅炉中产生,与蒸汽反应重新生成过氧化氢。由于溶液的化学性质,过氧化物消毒后的BMW可以进一步用热消毒法进行消毒,如蒸汽消毒(高压灭菌)。高压蒸汽消毒器可以作为设备的一个组成部分,或作为单独的设备。将化学消毒方法与热消毒方法相结合的做法至今没有得到应用,是因为所使用的消毒液在加热条件下不稳定,会形成氯气、溴及其氧化物,其他的消毒成分如戊二醛可能氧化为致癌物质或气化,成为可吸入有毒气体。The principle of action of the present invention is that the present invention discloses a method and apparatus for treating biological waste (BMW). The method and apparatus can perform the combination and sequential disinfection of several methods of crushing, peroxide disinfecting and heat disinfecting of BMW. Mixing of different types of disinfectants produces synergistic effects, while sequential disinfection processes achieve up to 100% sterilization. BMW will be comminuted and peroxide sterilized after entering the unit. Peroxide disinfection is a disinfectant mixture that is a disinfectant solution that has anti-virus properties and does not produce harmful gases and water pollution. For example, hydrogen peroxide can be chemically decomposed into oxygen and water, or react with organic matter to form carbon dioxide and water. , or ozone is produced in a steam boiler and reacts with steam to regenerate hydrogen peroxide. Due to the chemical nature of the solution, the peroxide-sterilized BMW can be further sterilized by thermal disinfection, such as steam sterilization (autoclaving). The autoclave can be used as an integral part of the equipment or as a separate unit. The combination of chemical disinfection methods and thermal disinfection methods has not been applied to date because the disinfectant used is unstable under heating conditions, forming chlorine, bromine and its oxides, and other disinfecting components such as glutaraldehyde may Oxidation to carcinogens or gasification, becoming an inhalable toxic gas.
过氧化氢消毒液以安全著称,被广泛应用于医疗行业。但其消毒效率相对较低,需要使用高浓度与长时间。然而,过氧化氢与乙酸反应可生成过乙酸,是一种非常有效的消毒液。过氧化氢与乙酸反应生成过乙酸有化学平衡,在标准状态下可产生少量的过乙酸。加入催化剂,如硫酸和无水乙 酸,则会有效加速过乙酸的产量,从而增强消毒效果。因此使用过氧化氢,乙酸,过乙酸和催化剂成分的消毒液被最终采用,这主要是考虑到其环保、加热后稳定无毒、在催化剂作用下可有效消毒,及可快速制取的性质。然而,由于这种消毒液具有较大的表面张力,为了达到良好的消毒效果,则需要添加表面活性剂并可在需要时施以粉碎、加压。激活的过氧化氢(即过氧化氢在催化剂作用下与乙酸反应生成过乙酸)作为消毒液,结合粉碎、混合、及高温高压下能渗入到生物医疗垃圾内部的消毒蒸汽,是一种有效且环保的医疗生物垃圾处理技术。Hydrogen peroxide disinfectant is widely used in the medical industry for its safety. However, its disinfection efficiency is relatively low, requiring high concentration and long time. However, hydrogen peroxide reacts with acetic acid to form peracetic acid, which is a very effective disinfectant. The reaction of hydrogen peroxide with acetic acid to form peracetic acid is chemically balanced, and a small amount of peracetic acid can be produced under standard conditions. Add catalysts such as sulfuric acid and anhydrous B Acid, it will effectively accelerate the production of peracetic acid, thus enhancing the disinfection effect. Therefore, the disinfectant using hydrogen peroxide, acetic acid, peracetic acid and catalyst components is finally adopted, which is mainly considered to be environmentally friendly, stable and non-toxic after heating, can be effectively disinfected under the action of a catalyst, and can be quickly prepared. However, since such a disinfectant has a large surface tension, in order to achieve a good disinfecting effect, it is necessary to add a surfactant and apply pulverization and pressurization as needed. Activated hydrogen peroxide (ie, hydrogen peroxide reacts with acetic acid under the action of a catalyst to form peracetic acid) as a disinfecting solution, combined with pulverizing, mixing, and disinfecting steam that can penetrate into the interior of biomedical waste under high temperature and high pressure, is effective and Environmentally friendly medical bio-waste treatment technology.
把粉碎、过氧化物消毒及热消毒三种功能结合在一起的方法,与把粉碎和过氧化物消毒或热消毒中的一种相结合的处理方法相比,这种三功能合一的处理技术具有协同性加强的消毒效果,过氧化物消毒首先减少了微生物存活量,蒸汽消毒同时增强了消毒液中的活性物质,在第二阶段完成微生物的彻底杀灭。The combination of the three functions of pulverization, peroxide sterilization and heat sterilization is compared with the treatment method combining one of pulverization and peroxide sterilization or heat sterilization, and the three-function treatment is combined. The technology has a synergistic and enhanced disinfection effect. The peroxide disinfection first reduces the microbial survival, the steam disinfection simultaneously enhances the active substance in the disinfectant, and completes the complete killing of the microorganism in the second stage.
此外,与热消毒相比,采用粉碎、一般浓度的过氧过物消毒结合装有高浓度过氧化物消毒液的混合反应器的消毒方法可以取得同样的灭菌效果。In addition, the same sterilization effect can be achieved by using a sterilizing method of pulverization, general concentration of peroxygen sterilization, and a mixed reactor equipped with a high concentration of peroxide disinfectant, as compared with heat sterilization.
本发明相对于现有技术具有如下的优点及效果:The present invention has the following advantages and effects over the prior art:
一、消毒灭菌效果好;采用本方法及设备对生物医疗废弃物进行处理,具有非常好的杀菌消毒效果,具体表现有以下几方面:First, the disinfection and sterilization effect is good; the method and equipment for the treatment of biomedical waste, has a very good sterilization and disinfection effect, the specific performance has the following aspects:
1、把粉碎和一般浓度过氧化物消毒液消毒,及热消毒和高浓度消毒液消毒中的一种结合在一起的方法,与把粉碎和过氧化物消毒或者粉碎和热消毒结合中的任一种处理方法相比,这种多功能合一的处理技术具有协同加强消毒的效果,第一阶段过氧化物消毒首先减少了微生物存活量,蒸汽消毒或高浓度消毒液消毒同时增强了消毒液中的活性物质,在第二阶段完成微生物的彻底杀灭;因而消毒效果非常好,完全可以达到国家及地域性替代处理技术协会(STAATT)制定的6个数量级的细菌消毒效率。1. A method of combining pulverization with a general concentration of a peroxide disinfectant, and a combination of heat sterilization and high-concentration disinfectant disinfection, in combination with pulverization and peroxide sterilization or pulverization and heat sterilization. Compared with a treatment method, the multi-functional treatment technology has the synergistic effect of strengthening disinfection. The first stage of peroxide disinfection first reduces the microbial survival, and the steam disinfection or high-concentration disinfectant disinfection simultaneously enhances the disinfectant. The active substance in the second stage completes the complete killing of the microorganisms; thus the disinfection effect is very good, and it can fully meet the disinfection efficiency of 6 orders of magnitude developed by the National and Regional Alternative Treatment Technology Association (STAATT).
2、采用本方案进行消毒,第二阶段的高浓度过氧化物消毒过程仅需3-10分钟。而且该第二阶段高浓度消毒也是第一阶段消毒的延续,所以第一阶段的时间根据粉碎过程所需时间灵活控制。这样,两个阶段的总体消毒过程仍然能够控制在5-10分钟之内。而现有其它技术如果需要实现相同的消毒效果,其时间一般超过30分钟。所以相比较而言,采用本方案可以大大节省操作时间,充分提高处理效率,明显促进生产量,具有非常好的经济效益。2, using this program for disinfection, the second stage of high-concentration peroxide disinfection process takes only 3-10 minutes. Moreover, the second-stage high-concentration disinfection is also a continuation of the first-stage disinfection, so the first-stage time is flexibly controlled according to the time required for the crushing process. In this way, the two-stage overall disinfection process can still be controlled within 5-10 minutes. Other existing technologies generally require more than 30 minutes for the same disinfection effect. Therefore, in comparison, the use of this scheme can greatly save operating time, fully improve processing efficiency, significantly promote production volume, and has very good economic benefits.
3、本发明首先在低浓度过氧化物消毒液中粉碎、之后再在混合反应器中使用高浓度消毒液进行增强处理、从而达到比现有处理方法更加高速同时也更加高效的处理结果。该方法可以有效缩短消毒时间,消毒液的消耗则较小,且没有污水排放;本方法使表面活性剂和洗涤剂在使用高浓度过氧化氢消毒之前作用于废弃物,同时又取得了需要的杀毒效果,克服了仅用高浓度过氧化氢会与洗涤剂和表面活性剂产生反应,在粉碎的同时使用高浓度过氧化物消毒是不可行而且很危险的缺陷。3. The present invention first pulverizes in a low concentration peroxide disinfectant, and then uses a high concentration disinfectant in the mixing reactor for enhanced treatment, thereby achieving a higher speed and more efficient processing result than the existing treatment method. The method can effectively shorten the disinfection time, the consumption of the disinfectant is small, and there is no sewage discharge; the method enables the surfactant and the detergent to act on the waste before being disinfected with high concentration hydrogen peroxide, and at the same time obtains the required The anti-virus effect overcomes the problem that only a high concentration of hydrogen peroxide reacts with detergents and surfactants, and it is not feasible and dangerous to use high concentration peroxide disinfection while pulverizing.

The invention mainly uses hydrogen peroxide as a main component for disinfection, hydrogen peroxide can be decomposed into water and oxygen, and ozone may be generated when it is in contact with air at a high temperature, and ozone formation is very favorable and safe for sterilization. Because it will degrade when it encounters steam; therefore, this technology does not produce substances that have obvious pollution to the environment, and has no adverse effect on air and water resources, completely avoiding the existing sterilization and disinfection methods often produce toxic and harmful The problem of material pollution of the environment, and thus the solution of the invention is relatively friendly to the environment, and is very environmentally friendly.
2、采用本发明还可以将消毒液回收重复循环利用,在减少排放的同时可以充分利用消毒液,节约原材料资源,减少物质损耗,节能降耗,同样具有良好的环保效果。2. The invention can also recycle and recycle the disinfectant, and can fully utilize the disinfectant while reducing emissions, save raw material resources, reduce material loss, save energy and reduce consumption, and also have good environmental protection effects.
三、智能化程度高;本方案采用控制器对相关装置进行操控,同时采用在线分析器对装置中的相关参数与及消毒液的相关浓度进行监控,可以实现自动化程度较高的智能控制,有利于降低操作者的劳动强度,提高生产效率,促进生产质量,保证操作效果的稳定性及安全性。Third, the degree of intelligence is high; the program uses the controller to control the related devices, and uses the online analyzer to monitor the relevant parameters in the device and the relevant concentration of the disinfectant, which can achieve intelligent control with high degree of automation. It is beneficial to reduce the labor intensity of the operator, improve production efficiency, promote production quality, and ensure the stability and safety of the operation effect.

此外,配制剂可能还含有其他领域内已知的物质,用以保护反应仓100中与过氧化氢溶液接触的部件(如机械部件,反应池102及粉碎机104的部件)不受过氧化氢腐蚀,或用来降低部件之间的摩擦系数。任选地,可以添加润滑油(如无硅润滑油)以保护反应仓100中与过氧化氢接触的部件。并且,为了使润滑油和水性消毒液更好地融合,可以添加一种醇(如异丙醇)和矿物油。在非限制性实施例中,矿物油包含聚山梨醇酯(TWEEN)与油酸聚乙二醇甘油酯中的一种以上。作为可选项,更多的能够促进润滑油与水性溶液融合的乳化剂已经在世界专利WO 2003/074027中描述,并收录在此作为参考。In addition, the formulation may also contain materials known in other fields to protect the components of the
在非限制性实施例中,消毒液可以包含过氧化氢以及稳定剂(包括过氧乙酸和乙酸)、激活剂(硫酸、无水乙酸和铁粉中的一种)。配制剂可能包含以下物质中的一种以上:烷基二甲基苄基氯化铵,辛基癸基二甲基氯化铵,辛基癸基二甲基溴化铵,二癸基二甲基氯化铵和二癸基二甲基溴化铵,同时还可能包含以下物质中的一种以上:无硅润滑油,醇类(如异丙醇)和矿物油(如聚山梨醇酯与油酸聚乙二醇甘油酯)。In a non-limiting embodiment, the disinfecting solution may comprise hydrogen peroxide as well as stabilizers (including peracetic acid and acetic acid), activators (one of sulfuric acid, anhydrous acetic acid, and iron powder). The formulation may comprise one or more of the following: alkyl dimethyl benzyl ammonium chloride, octyl decyl dimethyl ammonium chloride, octyl decyl dimethyl ammonium bromide, dimercapto dimethyl Ammonium chloride and dimercaptodimethylammonium bromide, and may also contain more than one of the following: silicone-free lubricants, alcohols (such as isopropanol) and mineral oils (such as polysorbates) Oleic acid polyethylene glycol glyceride).
将消毒液与配制剂混合将产生具有活性的消毒液。通常,消毒液的活性随着时间衰减,因此,根据对消毒液中消毒成分过氧化氢的最低活性要求,消毒液有确定的使用时限。活性的衰减在未与废弃物混合的状态下也可能由于消毒液与配制剂之间的化学反应而发生。在非限制性实施例中,消毒液的活性在混合后的24小时内由100%衰减至50%。因此在混合后的1个小时内,消毒液是可以使用或重复使用的。作为可选项,消毒液可以在水性环境下使用。 Mixing the disinfectant with the formulation will result in an active disinfectant. Generally, the activity of the disinfectant decays with time, and therefore, the disinfectant has a defined time limit based on the minimum activity requirement for the disinfecting component hydrogen peroxide in the disinfectant. The attenuation of the activity may also occur due to a chemical reaction between the disinfectant and the formulation in a state where it is not mixed with the waste. In a non-limiting embodiment, the activity of the disinfectant is attenuated from 100% to 50% within 24 hours of mixing. Therefore, the disinfectant can be used or reused within 1 hour after mixing. As an option, the disinfectant can be used in an aqueous environment.
图6a为质量浓度为0.5%的过氧化氢消毒液与不同种类的化学物质(包括2种季胺类物质Galsept50(一种含有4种季氨化合物的光谱消毒剂,暂无中文译名)和Septol(洗必太,又名氯己啶,学名双氯苯双胍己烷),以及一种戊二醛与季胺类物质的混合物SterCid混合后对消毒效率的影响图;数据基于在将有机消毒产品与过氧化氢混合后的1小时和24小时后收集的样品。该图显示了在使用前的短时间内将过氧化氢与洗涤剂、表面活性剂和有机消毒液混合的必要性。过氧化氢与季胺类物质和/或戊二醛的混合物在混合后的1小时内表现出强于单独使用激活过氧化氢溶液的协同作用,5分钟内的消毒效果达到了6个数量级,但在混合后的24小时后效果显著降低,不及单独使用过氧化氢。图6a可以充分说明过氧化物溶液的消毒活性可以通过添加一种或多种配制剂得到进一步加强。Figure 6a shows a hydrogen peroxide disinfectant with a mass concentration of 0.5% and different types of chemicals (including two quaternary amines Galsept50 (a spectral disinfectant containing four quaternary ammonium compounds, no Chinese translation) and Septal (Ubidiacil, also known as chlorhexidine, scientific name chlorhexidine), and a mixture of glutaraldehyde and quaternary amines SterCid mixed with disinfection efficiency; data based on organic disinfection products Samples collected after 1 hour and 24 hours after mixing with hydrogen peroxide. This figure shows the necessity of mixing hydrogen peroxide with detergents, surfactants and organic disinfectants in a short time before use. The mixture of hydrogen and quaternary amines and/or glutaraldehyde exhibits a synergistic effect over the use of activated hydrogen peroxide solution within 1 hour after mixing, and the disinfection effect in 5 minutes reaches 6 orders of magnitude, but After 24 hours of mixing, the effect was significantly reduced, and hydrogen peroxide alone was not used. Figure 6a fully demonstrates that the disinfecting activity of the peroxide solution can be further enhanced by the addition of one or more formulations.
图6b为各种不同消毒剂及其消毒水平的数据图,包括质量浓度0.5%的季铵类(QA)市售产品,高温蒸汽灭菌器(使用AC121℃或AC135℃),质量浓度0.5%和5%的活化过氧化氢(AHPO),灭菌效率由枯草杆菌孢子的存活率分析确定。显示,需要2个或多个阶段的顺次消毒才能取得完全的杀菌灭活。两个阶段可以使用不同的消毒剂,或在第一阶段使用适度热蒸汽消毒在第二阶段使用消毒剂,或在第一阶段使用消毒剂而在第二阶段使用热消毒。在所有的情况下,第一阶段后都没有达到彻底灭活,而在第二阶段之后,所有检验样品都达到完全灭活。顺次消毒阶段的需要,是因为第一阶段过程中对使用高浓度消毒剂的限制,因为高浓度活化过氧化氢、加上另外加入的的洗涤剂、润滑油及表面活性剂、对撕碎机造成损坏威胁。另一方面,顺次处理显著地缩短消毒过程,并实现完全灭活效果,而这种完全灭活的效果在使用单一消毒方式时,不论是使用化学消毒剂还是使用适度热蒸汽进行消毒,都不能达到。Figure 6b is a data plot of various disinfectants and their disinfection levels, including quaternary ammonium (QA) commercial products with a mass concentration of 0.5%, high temperature steam sterilizer (using AC121 ° C or AC 135 ° C), mass concentration 0.5% And 5% activated hydrogen peroxide (AHPO), the sterilization efficiency was determined by the survival analysis of B. subtilis spores. It is shown that two or more stages of sequential disinfection are required to achieve complete sterilization and inactivation. Different stages of disinfectant can be used in both stages, or disinfectant can be used in the second stage using moderate thermal steam sterilization in the first stage, or disinfectant in the first stage and thermal disinfection in the second stage in the second stage. In all cases, complete inactivation was not achieved after the first stage, and after the second stage, all test samples were completely inactivated. The need for a sequential disinfection phase is due to the limitation of the use of high-concentration disinfectants during the first phase, because of the high concentration of activated hydrogen peroxide, plus the addition of detergents, lubricants and surfactants, to shredding The machine poses a threat of damage. On the other hand, sequential treatment significantly shortens the sterilization process and achieves a complete inactivation effect, which is achieved when using a single disinfection method, whether using chemical disinfectants or using moderately hot steam. Can not reach.

图1E是图1A中的粉碎机104的一个实施例。粉碎机104安装于反应池102内。控制器110控制粉碎机104在反应池102内部将废弃物进行粉碎。任选地,粉碎机104可包含一个或多个粉碎
组件,如预粉碎机104a和最终粉碎机104b。例如,废弃物可首先由预粉碎机104a进行粉碎,打碎外盒、挡网及其他较大的废弃物体,形成颗粒大小在10-50厘米(长度)的废弃物。废弃物颗粒接下来由粉碎机104b进一步粉碎,将颗粒尺寸控制在0.5-1英寸。控制器110可操控预粉碎机104a和最终粉碎机104b同时或按顺序工作。或者,预粉碎机104a进行粉碎后,废弃物进入104b进行最终粉碎。或者,预粉碎机104a可由能够打碎废弃物的压杆代替,以改善粉碎机104b的吃料效果。任选地,图1C中的滤网120之下可另外添加一个粉碎机,比如高速粉碎机。控制器110可操控此新增的粉碎机对通过滤网120的废弃物进行进一步粉碎,将废弃物颗粒尺寸降低到1英寸以下。此外,新增的粉碎机可在打开图1C中的阀门126并释放反应池102中的消毒溶液之前将粉碎后的废弃物与消毒溶液进行混合。FIG. 1E is an embodiment of the

图2表示的是基于另外一个实施例的一种处理废弃物的设备200。设备200与图1A中的反应仓100非常相似,不同点在于处理后的废弃物在料仓202(对应于上面图1A中的反应池102)中进行了热消毒。设备200包含控制器210,对应于控制器110,可控制设备200中所有部件的运行。料仓202装有盖子212。当盖子212打开或部分打开时,废弃物即通过入口216进入设备。任选地,入口216也可以用来移除经过过氧化物消毒和热消毒的粉碎废弃物。控制器210可操控连接到容器206b的药剂分配器206a向料仓202中通过进口236注入206b中所盛放的消毒液,或操控连接到容器206d的药剂分配器206c向料仓202中通过进口236注入盛放于206d的配制剂。消毒液和配制剂混合后可产生过氧化物消毒溶液,在粉碎机204(由控制器210控制)工作的同时对废弃物进行消毒。任选地,控制器210可操控加热器240对料仓202进行加热,为消毒提供合适的温度环境(比如60-70℃)。因此,控制器210打开阀门226a,让含有过氧化物的消毒溶液通过出口226流出料仓202。任选地,排出的液体可作为消毒溶液再次使用,或直接排出设备200。在进行热消毒之前,控制器要先操控活塞242a工作。242a活塞下压,协助液体排出,也向粉碎并消毒后的废弃物加压,从而减小热消毒后由蒸汽填充的体积。此外,控制器210也可操控加热器240将料仓202加热到热消毒所需要的温度(例如121-140摄氏度)。Figure 2 shows an
图3A是一个概念图解,表示的是一个在线分析器360,用于评定图1A和图2所示的反应仓100和设备200工作过程中的消毒效率。为了解释方便,图3A将用图1A-F中的控制器110讲解,但对图2中的控制器210也同样适用。控制器110操控检测器360从增强消毒器108(如高压蒸汽灭菌器或者混合反应器)中抽取液体样本,并检测其需氧量(由于存活的细菌所致),从而反映系统的杀菌效果。控制器110控制开启阀门364,通过入口362向圆柱形容器366中输入样本。接下来,样本通过旋转过滤器368(如0.22微米过滤器,0.45微米过滤器等)过滤,将微生物(如细菌
等)从消毒液溶液中分离出来,获得浓缩的微生物。过滤后,过滤器用蒸馏水冲洗,以去除残留的消毒液(过氧化氢)。控制器110打开阀门372,使水从入口370流入,并由出口374流出。随后,控制器110关闭阀门376,将过滤器旋转到垂直状态,打开阀门372从而通过入口370向圆柱形容器366中提供细菌生长媒介。作为可选项,圆柱形容器366还装有呼吸通气管,以排除其中多余的空气。接下来,控制器110旋转过滤器368,使过滤器368上捕获的细菌落入圆柱形容器366中的生长媒介中并均匀化。任选地,控制器通过操控装有变速传动器的电机来控制过滤器368的旋转。生长媒介中的含氧量由氧电极测量。控制器获取氧含量数据并根据测量结果分析氧气的消耗量。氧气的消耗意味着有微生物存活,那么消毒过程是失败的,而如果含氧量保持不变,则意味着消毒过程成功。任选地,控制器110向用户提供消毒过程成功或失败的指示。任选地,控制器110向反应仓100提供信号,从而实现根据情况实时调节消毒流程。在非限制性实施例中,模块360与设备200相连,当检测到消毒失败时将自动停止粉碎和消毒设备的工作。在预设的时间(1-5分钟)后,控制器110打开阀门376将生长媒介通过出口374排出,并将过滤器368调节到水平位置。Figure 3A is a conceptual diagram showing an inline analyzer 360 for assessing the sterilization efficiency of the
图3B和图3C是图3A所示在线分析器360的实例图。检测由控制器110或自主控制器控制。当高压灭菌炉或混合反应器108中的消毒过程结束时,固体和液体的混合物被排放到图5所示的固液分离器。在排放时,阀门364打开,所排放液体的样品(步骤420)通过入口362连接的管道流入圆柱形容器366。在这个阶段过滤器368处在水平状态,液体样品经过过滤网368(步骤422),样品中的细菌被收集到过滤网上,液体则由打开的阀门376通过出口374排出。如果需要保证有足够的液体样品流过过滤网,可将一个真空泵连接到出口374。当取样完成时,阀门364关闭,阀门372打开,让蒸馏水灌382中的水流入圆柱形容器366。蒸馏水冲洗圆柱形容器和过滤器,清除残余的消毒液(步骤424)。控制器110关闭阀门376,电机380旋转过滤网到垂直状态。在此阶段,控制器110打开阀门370来让容器384中的生长媒介充满圆柱形容器366(步骤428),多余的空气则通过通气管386排出。当圆柱形容器366充满生长媒介时电机380旋转过滤器368,使细菌掉落到生长媒介中并使之均匀化(步骤430)。在旋转过滤器的同时,氧电极388分析圆柱形容器366中生长媒介的含氧量水平,控制器110则通过设定算法计算出含氧量的变化(步骤432)。如果含氧量分析显示含氧量有降低(步骤440),则控制器110将停止粉碎机的运作。3B and 3C are diagrams of examples of the line analyzer 360 shown in Fig. 3A. Detection is controlled by
图4是图1A、图1B,图2和图3中所示的处理生物垃圾方法的流程图。任选地,废弃物被装载到料仓中(步骤400)。已经激活的过氧化氢、稳定剂及配制剂被分配到废弃物上,过氧化氢、配制剂混合后形成消毒溶液并需要在其形成之后的6小时(或7、8、9、10、11、12、13小时)之内用于与垃圾接触消毒。任选地,可以通过向消毒溶液中添加过氧化氢、稳定剂和配制剂使其活性持续更长时间。在非限制性实施例中,过氧化氢,稳定剂和配制剂可通过泵打入设备200。在非限制性实施例中,激活的过氧化物和稳定剂通过第一个药剂分配器分配,而稳定剂则通过第二个药剂分配器分配。在另一非限制性实施例中,对过氧化物、稳定剂、及配制剂的分配由控制器通过一个或多个阀门及一个或多个泵来控制。已激活的过氧化物、一种或多种稳定剂、以及配制剂可以同时分配到料仓中,或者过氧化物、一种或多种稳定剂、以及配制剂首先混合好然后再喷洒至料仓中。在非限制性实施例中,稳定剂可能含有过乙酸、乙酸。在非限制性实施例中,配制剂可能是非离子
表面激活剂、阳离子表面活性剂、或阴离子表面活性剂、或洗涤剂。在另一非限制性实施例中,配制剂中可能含有一种或多种已知的具有抗菌活性的表面活性剂或洗涤剂。在另一非限制性实施例中,配制剂可能含有一种或多种具有抗菌活性的诸如季氨类化合物的表面活性剂。在另一非限制性实施例中,配制剂可能包含从以下季氨类化合物中选出的一种或几种:烷基二甲基苄基氯化铵,辛基癸基二甲基氯化铵,辛基癸基二甲基溴化铵,二癸基二甲基氯化铵和二癸基二甲基溴化铵。此外,配制剂还可能含有其他已知的合适成分,如无硅润滑油。此外,为了使润滑油和消毒液更好地融合,可以添加醇类(如异丙醇)和矿物油。在非限制性实施例中,矿物油可以包含聚山梨醇酯(TWEEN)与油酸聚乙二醇甘油酯中的一种或多种。4 is a flow chart of the method of processing biowaste shown in FIGS. 1A, 1B, 2, and 3.

Optionally, the activity can be sustained for a longer period of time by the addition of hydrogen peroxide, a stabilizer and a formulation to the disinfecting solution. In a non-limiting embodiment, hydrogen peroxide, a stabilizer, and a formulation can be pumped into
废弃物在粉碎的同时与消毒溶液混合,从而促进废弃物与消毒溶液充分接触(步骤404)。在非限制性实施例中,在第一阶段消毒处理中,为了对生物医疗垃圾进行有效的消毒,废弃物应该浸入消毒液中至少1分钟,或至少2分钟,或至少3分钟,或至少4分钟,或至少6分钟,或至少7分钟,或至少8分钟,或至少9分钟,或至少10分钟,或至少11分钟,或至少12分钟,或至少15分钟。每种可能性均代表本发明的一个独立的实施例。任选地,废弃物的粉碎和过氧化物消毒在单独一个料仓内完成。The waste is mixed with the disinfecting solution while being pulverized, thereby facilitating sufficient contact of the waste with the disinfecting solution (step 404). In a non-limiting embodiment, in the first stage of sterilization, in order to effectively disinfect the biomedical waste, the waste should be immersed in the disinfectant for at least 1 minute, or at least 2 minutes, or at least 3 minutes, or at least 4 Minutes, or at least 6 minutes, or at least 7 minutes, or at least 8 minutes, or at least 9 minutes, or at least 10 minutes, or at least 11 minutes, or at least 12 minutes, or at least 15 minutes. Each possibility represents a separate embodiment of the invention. Optionally, the comminution of the waste and the disinfection of the peroxide are done in a single silo.
在粉碎和消毒后(步骤404),消毒混合溶液将返回步骤402进行再利用,以减少消毒液的消耗和环境排放;处理后的废弃物会进入高压蒸汽灭菌炉进行最后的蒸汽灭菌,或进入混合反应器接触高浓度消毒液并持续3-5分钟(步骤406)。任选地,为应对细菌浓度过高或有机物成分过多的情况,持续消毒时间可以长至15分钟。After comminution and disinfection (step 404), the sterilized mixed solution will be returned to step 402 for reuse to reduce disinfectant consumption and environmental emissions; the treated waste will enter a high pressure steam sterilizer for final steam sterilization. Or enter the mixing reactor to contact the high concentration disinfectant for 3-5 minutes (step 406). Optionally, in order to cope with excessive bacterial concentrations or excessive organic constituents, the duration of the sterilization can be as long as 15 minutes.
任选地,在废弃物进行粉碎和过氧化物消毒后(步骤405或406),通过在线分析器360可对消毒溶液取样分析需氧量并与阈限对照,以检测消毒液的消毒的效果(步骤407)。在非限制性实施例中,当需氧量未超过阈限时,可认为消毒液活性达标,系统流程继续运行。任选地,在确定步骤408的检测结果合格后,消毒液在固液分离(步骤410)后返回并进行再利用。任选地,处理后的粉碎废弃物会进入挤压机并挤压(步骤412),消毒液体会返回步骤406,因此没有液体排放,而固体则可用于回收再利用。Optionally, after the waste is pulverized and peroxide sterilized (step 405 or 406), the disinfecting solution can be sampled and analyzed by the inline analyzer 360 to analyze the oxygen demand and be compared with a threshold to detect the disinfecting effect of the disinfecting solution. (Step 407). In a non-limiting embodiment, when the oxygen demand does not exceed the threshold, the disinfectant activity is considered to be up to standard and the system flow continues to operate. Optionally, after the test result of the determining
