Definitions

  • the invention relates to an environmentally friendly and efficient deodorant similar to plant liquid and a preparation method thereof, belonging to the technical field of deodorants.
  • Odor refers to all gaseous substances that stimulate the olfactory organs, cause unpleasantness and damage the living environment and human health. It usually includes the following 6 types of substances: nitrogen-containing substances, such as ammonia, trimethylamine, etc.; sulfur-containing substances, such as hydrogen sulfide, Methyl mercaptan, dimethyl disulfide, etc.; halogen-containing species, such as trichlorofluoromethane, dichloromethane, etc.; carbonyl-containing species, such as acetone, butanone, etc.; hydrocarbons, such as alkanes, olefins, aromatic hydrocarbons, etc.; Organic acids, such as valeric acid, isovaleric acid, etc.
  • nitrogen-containing substances such as ammonia, trimethylamine, etc.
  • sulfur-containing substances such as hydrogen sulfide, Methyl mercaptan, dimethyl disulfide, etc.
  • halogen-containing species such as trichlor
  • the source of its release mainly comes from industrial production and manufacturing, livestock and poultry breeding and some sanitation facilities, such as sewage treatment plants, domestic waste transfer stations, biomass aerobic/anaerobic treatment units, landfills, and domestic wastes generated in the process of household consumption. storage space and the body's own emissions.
  • the odor threshold of malodorous substances is extremely low, so it is easy to be perceived by people's sense of smell, causing olfactory stimulation.
  • malodorous substances will not only damage the environment, such as reducing stratospheric ozone, forming ground-level ozone through photochemical reactions, etc., but also harm the health of people exposed to malodorous environments through toxic and carcinogenic effects, for example, in a short period of time.
  • Some facilities such as garbage collection buckets (boxes), transfer stations, public toilets, septic tanks, etc., are very close to residential areas, making people come into contact with odors a lot, while in other release scenarios, the occupational exposure time of staff is usually longer. . Therefore, odor control is currently a very important task in environmental protection.
  • the technologies for treating malodorous gas can be divided into three categories: physical method, chemical method and biological method.
  • Physical methods mainly include diffusion dilution, absorption, adsorption, condensation and membrane separation; chemical methods include absorption, combustion, plasma reaction, Fenton oxidation, photocatalytic oxidation, electrocatalytic oxidation and other technologies; biological methods degrade malodor (odor) through microbial metabolism substance.
  • Odor peculiar smell
  • Odor is composed of some substances with extremely low concentration (usually at ppb level), and its characteristic pollutants are mainly sulfur-containing and nitrogen-containing substances, while combustion methods, adsorption methods, biological methods, etc.
  • Deodorants are widely used in the field of odor (odor) control because they can not only remove the odor from non-point sources by spraying, but also treat the odor gas collected in a centralized manner.
  • odor odor
  • most of the deodorants currently on the market, or the published deodorant patents use the strong aroma of the deodorant to cover up the odor and do not remove the odor-causing compounds; some deodorants use sodium hypochlorite, hydrogen peroxide/ Strong oxidizing systems such as acid/ferrous ions remove odor-causing compounds through a violent chemical reaction. This kind of deodorant is usually expensive, and long-term use will corrode equipment.
  • some stabilizers are usually added to the deodorant. to ensure system stability.
  • the removal efficiency of these deodorants for major odor-causing compounds such as sulfur is usually only 80-90%, and they are not suitable for non-point source odor control occasions that are in direct contact with the human body, failing to meet the requirements of health and environmental protection.
  • the present invention provides an environmentally friendly and efficient deodorant similar to plant liquid and a preparation method thereof.
