Description
본 발명은 하수 처리장에서 배출된 처리수를 중수로 이용하기 위한 방법에 관한 것이다. 더욱 상세하게는, 하수 처리장에서 생물학적 처리 과정을 거쳐서 배출되는 하수 처리수를 화장실 세척수, 세차 용수 등의 중수로 이용하기 위한 처리 방법에 관한 것이다.The present invention relates to a method for using treated water discharged from a sewage treatment plant as heavy water. More specifically, the present invention relates to a treatment method for using sewage treatment water discharged through a biological treatment process in a sewage treatment plant as heavy water such as toilet washing water and car wash water.
하수 처리장에서 생물학적인 방법을 통해 처리된 후 배출된 하수 처리수는 수질이 양호하고 수량이 풍부하며 안정적이므로, 화장실 세척수, 청소용수, 세차용수, 조경용수 등의 중수로서 매우 유용하다. 따라서 하수 처리장에서 배출된 처리수를 중수로서 재이용하기 위한 많은 방법들이 제안되어 왔다.Sewage treated water discharged after being treated by biological method in sewage treatment plant is good as heavy water such as toilet washing water, cleaning water, car wash water, landscaping water, etc. because the water quality is good, quantity is abundant and stable. Therefore, many methods have been proposed for reusing treated water discharged from sewage treatment plants as heavy water.
이러한 종래의 방법들은 처리수에 잔존된 미생물 플럭(floc) 및 기타 콜로이드를 포함한 부유성 물질을 제거하기 위하여, 응집ㆍ침전법 또는 모래 여과법을 단독으로 사용하거나 2개 이상의 방법을 단계적으로 사용함으로써 처리하는 방법들이었다.These conventional methods are treated by using flocculation, sedimentation or sand filtration alone or two or more steps in order to remove suspended solids including microbial flocs and other colloids remaining in the treated water. How to do.
그러나 종래의 이러한 방법들은 매우 큰 부지 면적을 요구하고, 또한 하수 처리수의 재이용시에 문제가 되는 냄새와 색도가 효과적으로 제거되지 못하는 문제점이 있었다. 특히 하수취와 같은 냄새의 경우는 중수 이용자에게 매우 큰 불쾌감을 유발할 수 있으므로, 중수로의 이용에 큰 장애 요인이 되었다.However, these conventional methods require a very large site area, and also have a problem in that odor and color that are problematic when reuse of sewage treatment water cannot be effectively removed. In particular, smells such as sewage can cause very unpleasant feelings to heavy water users, which is a major obstacle to the use of heavy water.
상기와 같은 문제점을 해결하기 위해 여러 개선 방법이 제시되었다. 그 중에서 한외 여과, 정밀 여과, 역삼투막 여과 등의 방법이 있었으나, 이러한 막 분리 방법은 사용되는 막이 매우 고가일 뿐 아니라, 막의 오염에 의한 처리 효율 감소를 방지하기 위해 최대 처리량의 100배에 달하는 순환 유량을 유지하여야 하므로, 경제적이지 못한 단점이 있었다. 특히 하수 처리장과 같이 대규모의 처리 시설의 경우에는 이러한 막 분리 방법은 적용하기가 매우 어려웠다.In order to solve the above problems, various improvement methods have been proposed. Among them, there were ultrafiltration, microfiltration, reverse osmosis membrane filtration, etc. However, the membrane separation method is not only very expensive membrane, but also a circulating flow rate of 100 times the maximum throughput in order to prevent treatment efficiency reduction due to contamination of the membrane. Since it must be maintained, there was a disadvantage that is not economic. Especially in large-scale treatment plants such as sewage treatment plants, this membrane separation method has been very difficult to apply.
또 다른 개선 방법으로서, 한국 특허 공개 제97-65438호의 "하수 처리수를 재이용하는 중수도 시스템(FCS+Biofilter+RO)의 개발"이 있다. 이 방법은 플럭 형성지, 침전지, 안정화조, 그리고 미생물에 의한 수처리 공정인 바이오필터 및 염류 제거를 위한 역삼투막법으로 구성된 매우 복잡할 뿐만 아니라 매우 고가인 공정들로 이루어져 있다. 더구나 플럭 형성지와 침전지를 포함하고 있으므로, 소요되는 부지 면적이 매우 클 뿐만 아니라, 생물학적 처리 공정인 바이오필터 공정이 포함되어 있으므로, 동절기와 같이 기온이 낮은 경우에는 처리 효율이 현저히 떨어지고 운전이 매우 어려워지는 문제점이 있다. 또한 역삼투 공정은 매우 고가일 뿐 아니라, 운전 압력이 매우 높고, 순환 유속의 유지가 요구되므로, 매우 비경제적인 단점이 있었다.Another improvement method is the development of a heavy water system (FCS + Biofilter + RO) that reuses sewage treatment water in Korean Patent Publication No. 97-65438. The process consists of very complex and very expensive processes consisting of a flocculant, a sedimentation basin, a stabilization tank, and a reverse osmosis membrane for the removal of salt and biofilters, which are microbial water treatment processes. In addition, because it includes floc forming and sedimentation basins, the site area required is very large, and the biofilter process, which is a biological treatment process, is included. Therefore, when the temperature is low, such as winter, the treatment efficiency is significantly decreased and operation is very difficult. There is a problem losing. In addition, the reverse osmosis process is very expensive, the operating pressure is very high, and the maintenance of the circulation flow rate is required, there was a very uneconomical disadvantage.
본 발명은 상기한 바와 같은 종래 기술에 의한 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 요구되는 부지 면적을 최소화하고 공정을 간소화함으로써 경제적인 중수 생산 방법을 제공하고자 하는 것이다. 또한 종래 방법들로는 제거가 어려웠던 냄새 및 색도의 문제를 효과적으로 제거할 수 있는 중수 생산 방법을 제공하고자 하는 것이다.The present invention is to solve the problems caused by the prior art as described above, an object of the present invention is to provide an economical heavy water production method by minimizing the required site area and simplifying the process. In addition, the conventional methods are to provide a heavy water production method that can effectively eliminate the problem of odor and color that was difficult to remove.

본 발명에 의한 하수 처리수의 재이용을 위한 중수 생산 방법의 본질적인 특징은 응집제 및 유기 고분자 응집제 등의 약품의 혼합, 응집 및 침전 과정이 조 사이를 연결하는 관 내에서 일어나므로, 혼화, 응집 및 침전을 위한 조가 별도로 필요하지 않다는 점이다. 즉 별도의 조에서 응집제를 혼합하고 응집시키는 것이 아니라, 원수조와 여과조를 연결시켜 주는 관 내에 혼합기를 설치하여, 관 내에서 혼합과 응집 과정이 일어난다는 점이다. 본 명세서에서 사용하는 용어인 "인라인 믹서(In-line Mixer)"는 관 내에 설치되어서 응집제 등의 약품을 혼합하는 기기를 말한다. 이러한 인라인 믹서를 이용하면, 응집제 등의 혼합에 필요한 기계적 장치 및 동력을 필요로 하지 않으며, 더욱이 전체 시스템의 부피, 즉 요구되는 부지 면적이 현저히 줄어들게 되므로 비용을 상당히 절감할 수 있다.An essential feature of the heavy water production method for reuse of sewage treatment water according to the present invention is that the mixing, flocculation and precipitation processes of chemicals such as flocculant and organic polymer flocculant occur in the pipes connecting the tanks, so that the mixing, flocculation and precipitation There is no need for a separate pair. In other words, instead of mixing and flocculating the flocculant in a separate tank, a mixer is installed in the pipe connecting the raw water tank and the filtration tank, so that the mixing and flocculation processes occur in the pipe. As used herein, the term "in-line mixer" refers to a device installed in a tube to mix a drug such as a flocculant. The use of such an in-line mixer eliminates the need for mechanical devices and power for mixing flocculants and the like, and further reduces costs by significantly reducing the overall system volume, ie the required site area.
상기와 같은 인라인 믹서를 하수 처리수를 담은 원수조에서 최초의 여과조로 유입되는 관 사이에 설치하고, 그 인라인 믹서에 유기 고분자 응집제(폴리머)를 포함하는 응집제를 주입하여 혼합함으로써 하수 처리수에 잔존하는 미생물이나 기타 고형물들을 플럭으로 형성하도록 한 후, 이러한 플럭을 여과 단계를 거쳐 여과시킨다.The inline mixer as described above is installed between the pipes flowing into the first filtration tank from the raw water tank containing the sewage treatment water, and the flocculation agent containing the organic polymer flocculant (polymer) is injected into the inline mixer and mixed to remain in the sewage treatment water. The microorganisms or other solids are allowed to form flocs, which are then filtered through a filtration step.
이하, 첨부된 도면을 참조하면서 본 발명의 바람직한 일실시예에 의한 하수처리수 재이용을 위한 중수 생산 방법을 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the heavy water production method for reuse of sewage treatment water according to an embodiment of the present invention.

A plurality of water pumps 7 are provided at positions necessary for the flow of water. In addition, a water tank 8 was placed near the filter papers 3 and 4 and the activated carbon adsorption tower 5 to contain filtered or adsorbed treated water. In addition, a chemical tank 9 was installed between the inline mixer 2 and the raw water tank 1 to supply chemicals such as a flocculant and an organic polymer flocculant.
도1의 장치를 이용하여 하수 처리수를 2차 처리한 결과, 종래 기술에 의한 방법을 이용한 경우보다 현저히 적은 부지 면적을 차지하면서도, 수질이 우수한 중수를 생산할 수 있었을 뿐만 아니라, 냄새와 색도가 거의 제거되었음을 확인할 수 있었다.As a result of the secondary treatment of the sewage treatment water using the apparatus of FIG. 1, not only was it able to produce heavy water having excellent water quality, but also occupied significantly less land area than the conventional method. It was confirmed that it was removed.
본 발명에 의한 하수 처리수의 재이용을 위한 중수 생산 방법 및 그 장치를 이용하면, 처리 공정이 매우 간단해져서 소요 부지 면적과 처리 비용을 현저히 낮출 수 있을 뿐 아니라, 냄새와 색도가 거의 제거되어 수질이 매우 우수한 중수를 얻을 수 있었다. 따라서 본 발명에 의한 방법으로 처리된 중수를 이용하는 사용자들은 악취 및 색도에서 오는 불쾌감 없이 중수를 화장실 세척수, 청소 용수, 세차 용수, 조경 용수, 하천 유지 용수 등으로 사용할 수 있다.By using the heavy water production method and apparatus for the reuse of sewage treatment water according to the present invention, the treatment process becomes very simple, which significantly lowers the required site area and treatment cost, and almost eliminates the smell and color, thereby improving the water quality. Very good heavy water was obtained. Therefore, users using the heavy water treated by the method according to the present invention can use the heavy water as toilet washing water, cleaning water, car wash water, landscaping water, river maintenance water, etc. without discomfort from odor and chromaticity.
