Description

토양오염 정화시스템{A soil purification system}A soil purification system

본 발명은 토양오염 정화시스템에 관한 것으로, 특히 오염된 토양에 지속적으로 물을 살포하여 기름등을 일정깊이로 관정된 집수정내로 집수한 다음 회수펌프로서 펌핑하여 유량조절조로 이송한 후 유수분리조에서 유수분리하고 순차적으로 화학약품처리조,오존산화장치를 거치도록 하여 물리적,화학적,생물학적 처리를 이룸은 물론 정화된 처리수는 재차 살포되는 과정이 리사이클되어 이루어질수 있도록 함으로서, 미생물처리가 어려운 심층오염이나 광범위한 오염지역을 신속하고도 완전하게 정화된 토양으로 복원할수 있도록 한 토양오염 정화시스템에 관한 것이다.The present invention relates to a soil pollution purification system, and in particular, by continuously spraying water on contaminated soil to collect oil and the like into a sump well determined at a predetermined depth, and then pumped as a recovery pump and transported to a flow control tank in an oil / water separation tank. Separation of oil and sequential chemical treatment tanks and ozone oxidizers to achieve physical, chemical and biological treatment, as well as purified water can be recycled and recycled, resulting in deep contamination It relates to a soil pollution purification system that enables the restoration of a wide range of contaminated areas to quickly and completely cleaned soil.

일반적으로 토양오염은 지하에 침투한 오염물질이 지질을 오염시키는 현상으로 이는 토양은 물론 지하수나 지하공기등 지질중에 존재하는 모든것이 대상이 되는 것이되며, 이렇게 오염된 토양정화사업은 과거에는 광산지역이나 핵폐기물처리지역에서 발생한 중금속 오염정화 중심이었다. 그러나 최근에는 군주둔지역, 반도체공장, 드라이클리닝, 도장공정등에서 사용되는 휘발성유기염소화합물에 의한 하이테크오염이 주를 이루고 있으며, 이러한 휘발성유기염소화합물은 발암성 물질로 판명이 나 있으며, 최근에는 드라이클리닝과 주유소 및 기름탱크 주변등의 일상생활에 밀접한 장소에서도 사용되어 도심지에서도 토양오염이 심각하게 발생되고 있는 것이 현 실정이다.In general, soil pollution is a phenomenon in which pollutants that penetrate underground contaminate the lipids, which is not only the soil but also all existing in the geology such as groundwater and underground air. It was centered on the purification of heavy metals from nuclear waste treatment areas. In recent years, however, high-tech pollution by volatile organic chlorine compounds used in military areas, semiconductor factories, dry cleaning and coating processes has been the main cause. These volatile organic chlorine compounds have been found to be carcinogenic, and recently, As it is used in places close to daily life such as cleaning, gas stations and oil tanks, soil pollution is seriously occurring in urban areas.

상기와 같은 휘발성유기염소화합물들은 토양중에서 추출하는 것이 어렵기 때문에 오염원 위치를 폐쇄하여 복토하는 방법등으로 정화하는 방법이 있는데 이는 오염토양을 정화하는 것이라기 보다는 오염원의 확산을 주 목적으로 하기 때문에 근본적인 해결책은 되지 못하는 것이고, 또 하나의 방법으로는 가열처리 방식이 있는데, 이 방식은 오염토양을 굴착하여 소각로에서 열을 가해 고온 휘발성의 오염물질을 토양과 분리하여 처리하는 방법으로서, 이는 비용이 과대하게 소모되고 소각로등 기타 시설물이 필요하게 되는 문제점이 있는 것이며, 나아가 생물학적 처리방법으로 미생물로서 오염원을 정화하는 방식등이 사용되고 있는데, 이러한 상기 방법들은 극히 초보적이고도 단순하여 그 정화정도가 극히 의심스러운 것이었음은 물론 토양상에 시설물이 건축되어 있는 경우에는 토취와 미생물처리가 불가능한 것일 뿐 아니라 태우는 방식은 대단히 많은 비용이 소모되고 좁은면적은 가능하지만 광범위한 지역은 불가능 한 것이었으며, 이와는 반대로 광범위한 지역에서의 미생물처리는 효과적이나 표층오염만이 정화가 가능한 것이고 심층에는 미생물을 식종하고 산소를 공급하기가 매우 어려워 심층오염은 정화시키지 못하는 등 여러가지 제반 문제점들이 발생되었다.Since these volatile organic chlorine compounds are difficult to extract from the soil, there are methods to purify them by closing and polluting the location of the source. This is because the main purpose is to spread the source rather than to clean the soil. There is no solution, and another method is the heat treatment method, in which the contaminated soil is excavated and heated in an incinerator to separate hot volatile contaminants from the soil, which is expensive. It is a problem that it is consumed and other facilities such as incinerators are needed, and furthermore, biological treatment methods are used to purify pollutants as microorganisms. These methods are extremely rudimentary and simple, and the degree of purification is extremely suspicious. Of course on the soil If the water is constructed, not only the intoxication and microbial treatment are impossible, but the burning method is very expensive and a small area is possible, but a large area is impossible. Only pollution can be cleaned and various problems have arisen such that it is difficult to plant microorganisms and supply oxygen to deep soils.

따라서 본 발명의 목적은 상기와 같은 종래의 문제점을 감안하여 안출한 것으로, 오염된 토양에 지속적으로 물을 살포하여 기름등을 일정깊이로 관정된 집수정내로 집수한 다음 회수펌프로서 펌핑하여 유량조절조로 이송한 후 유수분리조에서 유수분리하고 순차적으로 화학약품처리조,오존산화장치를 거치도록 하여 물리적,화학적,생물학적 처리를 이룸은 물론 정화된 처리수는 재차 살포되는 과정이 리사이클되어 이루어질수 있도록 함으로서, 건축되어지거나 건축중인 시설물등에 제약을 받지않고 토양복원이 가능할 뿐만 아니라 미생물처리가 어려운 심층오염이나 광범위한 오염지역을 신속하고도 완전하게 정화된 토양으로 복원하여 토지이용 가치를 극대화 할수 있도록 한 토양오염 정화시스템을 제공하는데 있다.Therefore, the object of the present invention is to devise in view of the above-mentioned conventional problems, by continuously spraying water on the contaminated soil to collect oil and the like into the wells determined to a certain depth and then pumped as a recovery pump to control the flow rate After transferring to the tank, the oil is separated from the oil-water separation tank and the chemical treatment tank and the ozone oxidation device are sequentially subjected to physical, chemical, and biological treatment, and the purified water can be recycled again. Soil remediation is possible without restraining the facilities that are being built or under construction, and the soil pollution purification that maximizes the value of land use by restoring deep and difficult polluted areas that are difficult to deal with microorganisms to quickly and completely purified soil. To provide a system.

Water absorbed on the surface of the soil gradually moves in the contaminated soil, and during the movement, oil penetrates into the soil, and moves together to purify the soil as it is collected in a sump, where the water contains hydrogen peroxide. Bubbles are generated due to the decomposition of hydrogen peroxide to increase the oxygen supply in the soil as well as to make the oil components easily fall out of the soil so that the oil is easily joined to the movement of water to be collected, and then to the sump 100 When a certain amount of waste water is collected and the water level detection sensor is detected, the recovery pump 200 is automatically operated and the collected waste water is a pumping force of the recovery pump 200 along the transfer pipe 210 as a pumping force ( 300 is stored.

상기 유량조절조(300)에 저장되어진 폐수는 일정량씩 유수분리조(400)로 이동하게 되고 유수분리조(400)에서는 유량조절조(300)로 부터 넘어온 폐수를 미세기포발생기등으로서 유류를 부상시켜 물과 기름으로 1차 유수 분리하게 되고 이 분리된 물은 하측부의 물탱크에 저장하고 기름은 분리유농축조(410)로 보내되어 저장되어 지게된다. 이때 상기 분리유농축조(410)에 저장된 기름은 회수되어 폐기처분되어 지게 되고 오염물질이 일부 남아 있게 되는 폐수는 화학약품처리조에서 약품을 처리하여 슬러지성분등을 처리하여 침전시키게 되고 침전물은 탈수기에서 탈수되어 폐기처분 되어 짐과 동시에 처리수는 인젝트 방식으로 오존산화장치(500)로 이송되어 지게 되며, 상기 오존산화장치(500)로 유입되어진 처리수에 아직도 남아있는 난분해성 오염원은 오존과 접촉됨으로서 산화처리되어 완전히 정화된 처리수를 얻게 되는데, 이때 상기 오존산화접촉시에 1∼30ppm 정도의 과산화수소를 추가하여 오염물질의 분해를 촉진하여 처리원가를 낮춤과 동시에 빠른 시간안에 완벽하게 정화된 처리수를 얻을수 있게 되는 것이다.Waste water stored in the flow control tank 300 is moved to the oil-water separation tank 400 by a predetermined amount, and in the oil-water separation tank 400, the waste water from the flow control tank 300 is floated as a microbubble generator, etc. Primary oil water is separated into oil and oil, and the separated water is stored in the lower water tank, and oil is sent to the oil separation tank 410 to be stored. At this time, the oil stored in the separated oil concentration tank 410 is recovered and disposed of, and the waste water in which some contaminants remain is treated by chemical treatment in the chemical treatment tank to be treated by sludge components, etc., and the precipitate is dehydrated. At the same time as the water is dehydrated and disposed of, the treated water is transferred to the ozone oxidation apparatus 500 by the inject method, and the hardly decomposable pollutants remaining in the treated water introduced into the ozone oxidation apparatus 500 come into contact with ozone. In this case, the treated water is oxidized and completely purified, and at this time, the ozone oxidation contact adds about 1 to 30 ppm of hydrogen peroxide to promote the decomposition of pollutants, thereby lowering the processing cost and at the same time, completely purifying the water. You will get a number.

상기 오존산화장치(500)의 적정오존 주입율을 구하기 위하여 실험한 결과 오존처리량에 따른 오염량 감소를 나타내는 표1에서 보는 바와 같이 법적기준치(n-H 5ppm 이하)에 부합하는 80mgO3/L과 100mgO3/L의오존주입율이 바람직 하며, 본 실험에 선택되어지는 오존산화장치(500)의 오존발생량은 2.0g/hr이며, 발생농도는 2%(Wt.)이다.80mgO 3 / L and 100mgO to meet the legal requirement (nH 5ppm or less), as shown in indicating the contamination quantity reduction according to the results of ozone throughput experiments to obtain an adequate ozone injection rate table 1 of the ozonation apparatus 500 3 / The ozone injection rate of L is preferable, and the ozone generation amount of the ozone oxidizer 500 selected in this experiment is 2.0 g / hr, and the concentration is 2% (Wt.).

상기의 오존산화장치(500)에서 난분해성 오염원이 완벽하게 처리된 처리수는 재차 살포기(600)로 공급되어 지게 되고 살포기(600)에서는 토양이 정화될때 까지 지속적으로 물을 뿌려주게 되고 이 물은 오염토양위로 꾸준히 침투하여 오염물질과 함께 집수정(100)으로 흘러들면서 정화가 이루어지는데, 이때 상기 살포기(600)에서 물을 살포시에 1∼100ppm정도의 과산화수소를 함유하여 살포하게 됨은 물론 기름분해 미생물도 함께 오염된 토양에 살포하게 됨으로서 토양에서 기름성분이 쉽게 떨어지게 될 뿐만 아니라 산소공급을 증대시키게 되어 생물학적처리 효율을 극대화 시키게 됨은 물론 집수정(100)에 더이상 오염된 폐수가 집수되지 않으면은 역으로 기름분해 미생물을 집수정에 투입하여 심층토양 속으로 스며들수 있도록 함으로서 오염토양의 복원이 가속화 되어 지는 것이다.In the ozone oxidizer 500, the treated water in which the hardly degradable pollutant is completely treated is supplied to the sprayer 600 again, and the sprayer 600 continuously sprays water until the soil is purified. Purification is continuously carried out on the contaminated soil and flows into the sump (100) with contaminants. At this time, the sprayer 600 contains about 1 to 100 ppm of hydrogen peroxide when the water is sprayed, as well as oil-degrading microorganisms. In addition, by spraying on the contaminated soil, not only oil component is easily dropped from the soil, but also increases oxygen supply, thereby maximizing biological treatment efficiency, and conversely, when the contaminated wastewater is no longer collected in the sump 100. Restoration of contaminated soils is possible by introducing oil-degrading microorganisms into the sump to allow them to seep into deep soils. It is being accelerated.
