More specifically, the landfill layer is surrounded by a bottom order layer and a vertical order wall, which is constructed to be inclined toward the sump. In a conventional landfill facility in which leachate, such as wastewater, generated from the effluent flows into a collection basin, the leachate collected in the collection basin is located between the vertical vehicle walls and is in communication with the sump. Through the leachate inlet provided therein, the upper nonwoven fabric layer of the internal adsorption and purification portion provided inside the sand, activated carbon, functional adsorbent, loess, etc., in order to pass through the adsorbent layer and lower nonwoven layer mixed in a predetermined ratio Various harmful substances contained in leachate are absorbed and removed. It relates to a landfill leachate purification device, characterized in that only the purified water is discharged to the outside through the water purification outlet of the lower back plate of the outer wall.
종래의 매립시설은 측면둘레를 따라 연직차수벽 및 제방을 설치하고 바닥면을 깊게 파 바닥차수층을 설치하며, 상기 바닥차수층에는 침출수집수관을 설치하거나 또는 바닥차수층 자체를 집수정쪽으로 경사지게 설치하여 쓰레기 등이 매립된 매립층에서 발생되는 오폐수 등의 침출수가 상기 침출수집수관 또는 경사진 바닥차수층을 따라 집수정으로 유입되도록 하고 상기 집수정에 일시적으로 저장된 침출수는 이송관을 통하여 인근 하수종말처리장으로 보내져 정화 처리된 후 정화된 물만 하천으로 방류하도록 되어 있다.Conventional reclamation facilities install vertical order walls and embankments along side circumferences and install a bottom order layer to dig deeply into the bottom, and install a leachate collection pipe on the bottom order layer, or install the bottom order layer inclined toward the sump and receive garbage. Leachate, such as wastewater from the buried landfill, is introduced into the sump along the leachate collection pipe or inclined bottom drainage layer, and the leachate temporarily stored in the sump is sent to a nearby sewage treatment plant through a transfer pipe for purification. After that, only purified water is discharged into the stream.
그러나, 이러한 종래의 매립시설은 자체 침출수처리장의 설치 및 운영비용이 높은 관계로 인근 하수종말처리장에서 하수와 함께 침출수를 처리하도록 함으로써 그 처리효율이 떨어지며, 또한 대부분이 노천 매립식이어서 빗물의 대부분이 침출수로 전환되어 침출수의 발생량이 많고, 집중호우 등으로 인해 강수량이 급격히 증가하는 경우에는 상기 집수정에 일시적으로 모인 침출수가 곧 바로 정화처리되지 못하고 이송관을 통해 인근 하수종말처리장으로 이송된 후 정화 처리해야 하므로 인근 하수종말처리장의 용량이 초과된 양의 침출수가 공급되면 침출수의 처리불능 사태가 발생되기도 하며, 침출수가 집수정에서 넘쳐 연직차수벽과 집수정사이의 부분으로 새어나와 외부로 유출됨으로써 정화되지 않은 침출수에 의해 매립시설 주변의 토양이나 하천이 오염되는 문제점이 있었다.However, such a conventional landfill facility has a high cost of installation and operation of its own leachate treatment plant, so that the treatment efficiency is reduced by treating the leachate with sewage at a nearby sewage treatment plant. When the leachate is converted to leachate and the amount of leachate is generated, and the precipitation increases rapidly due to heavy rainfall, the leachate temporarily collected in the sump is not immediately purified but is transported to a nearby sewage treatment plant via a transfer pipe. If the amount of leachate in excess of the capacity of the nearby sewage treatment plant is supplied, the leachate may not be treated, and the leachate overflows from the sump and leaks to the part between the vertical water tank and the sump and flows to the outside. Untreated leachate can cause soil around landfills There was a problem that the river is polluted.
본 고안은 상기와 같은 문제점을 해결하기 위한 것으로 간단한 구조로 되어 있어 설치 및 운영비용이 적게 들며, 매립시설 자체에 일체로 구비된 침출수 정화장치를 제공함으로써 매립층에서 발생되는 오폐수 등의 침출수를 신속하게 정화하여 배출하도록 하고 침출수가 연직차수벽과 침출수 정화장치의 사이부분으로 유출되지 않도록 하여 매립시설 주변의 토양이나 하천이 오염되지 않도록 하는 것에 그 목적이 있다.The present invention is designed to solve the above problems, has a simple structure and low installation and operation costs, by providing a leachate purification device that is integrally provided in the landfill facility itself to quickly leach water such as waste water generated in the landfill layer The purpose of this is to purify and discharge, and to prevent the leachate from flowing into the area between the vertical water barrier and the leachate purifier, so that the soil or rivers around the landfill facility are not contaminated.
이러한 목적을 달성하기 위하여 바닥면이 집수정쪽으로 경사지게 시공된 바닥차수층 및 연직차수벽으로 둘러싸여 있어 매립층에서 발생되는 침출수가 집수정쪽으로 흘러 모이도록 되어 있는 통상의 매립시설에 있어서, 상기 연직차수벽의 사이에 위치하며 집수정과 연설되어 있어 집수정에 모인 침출수가 외부벽체부의 전면판 상부에 구비된 침출수유입구를 통해 내측으로 유입되도록 되어 있고, 내측에 구비된 내부흡착정화부의 상부부직포층과 모래, 활성탄, 기능성 흡착제, 황토 등이 일정 비율로 혼합된 흡착제층과 하부부직포층을 차례로 통과하면서 침출수에 포함되어 있는 각종 유해물질이 흡착 제거되고 유해물질이 제거된 정수만이 외부벽체부의 후면판 하부의 정수배출구를 통해 외부로 배출되도록 되어 있고 상기 외부벽체부의 전면판 및 후면판의 양측면으로 돌출된 돌출턱에 의해 침출수가 외부로 유출되지 않도록 되어 있는 것에 본 고안의 특징이 있다.In order to achieve this purpose, in a conventional landfill facility in which the leachate generated in the buried layer flows toward the sump well, the bottom surface is surrounded by the bottom order layer and the vertical order wall which is inclined toward the sump well. The leachate collected in the sump is introduced to the inside through the leachate inlet provided in the upper part of the front wall of the outer wall, and the upper non-woven fabric layer of the inner adsorption purifier is provided with sand, activated carbon, Passing through the adsorbent layer and lower non-woven fabric layer in which functional adsorbents, ocher, etc. are mixed in a certain ratio, various harmful substances contained in the leachate are adsorbed and removed. Is discharged to the outside through the front plate and the outer wall portion The feature of the present invention is that the leachate is not leaked to the outside by the protruding jaws protruding from both sides of the rear plate.

각종 쓰레기 또는 폐광물이 매립된 매립시설(7)의 매립층(6)에서 발생된 침출수는 바닥면이 집수정(2)쪽으로 경사지게 시공된 통상의 바닥차수층(3)을 따라 흘러 내려 집수정(2)으로 모이게 되고 집수정(2)에 일시적으로 모인 침출수는 외부벽체부(8)의 전면판(10) 상부에 형성된 침출수유입구(11)를 통해 내측으로 유입되고, 내부흡착정화부(9)의 상부부직포층(15)에서 1차적으로 각종 쓰레기 등의 입자가 큰 이물질이 걸러진 다음 활성탄과 모래와 기능성흡착제 등이 고르게 혼합된 흡착제층(16)을 통과하면서 각종 중금속 등의 유해물질이 흡착 제거되고, 하부부직포층(17)을 통과하면서 다시한번 미세한 이물질이 걸러진 후 각종 이물질이나 중금속 등의 유해물질이 제거된 정수만 흡착제층받침판(18)에 형성된 다수개의 정수유출공(19)을 통해 하부의 공간부(20)로 유입되고 외부벽체부(8)의 후면판(12) 하단부에 형성된 정수배출구(13)를 통해 외부로 배출된다.The leachate generated in the landfill layer 6 of the landfill facility 7 in which various wastes or waste minerals are buried flows down along the ordinary bottom order layer 3 in which the bottom surface is inclined toward the sump 2. Leachate collected in the collection well (2) temporarily flows inward through the leachate inlet (11) formed on the front plate 10 of the outer wall portion (8), the interior of the adsorption purification section (9) In the upper nonwoven fabric layer 15, foreign substances having large particles such as various wastes are filtered out first, and then harmful substances such as various heavy metals are adsorbed and removed while passing through the adsorbent layer 16 in which activated carbon, sand, and functional adsorbent are evenly mixed. After passing through the lower non-woven fabric layer 17, fine foreign matters are filtered again, and only the purified water from which various foreign substances and heavy metals are removed is removed from the lower space through the plurality of purified water outlet holes 19 formed in the adsorbent layer support plate 18. Part (20 Inflow to the outside and through the water discharge port 13 formed in the lower end of the rear plate 12 of the outer wall portion (8).
상기와 같이 본 고안에 의하면 침출수 정화장치가 간단한 구조로 되어 있어 설치 및 운영비용이 적게 들며, 매립시설 자체에 일체로 구비된 침출수 정화장치를 제공함으로써 매립층에서 발생되는 오폐수 등의 침출수를 신속하게 흡착 정화처리하여 배출할 수 있고 외부벽체부에 형성된 돌출턱에 의해 침출수가 연직차수벽과 침출수 정화장치의 사이로 유출되지 않아 침출수의 범람이나 유출로 인해 매립시설 주변의 토양이나 하천이 오염되는 것을 방지할 수 있는 효과가 있다.As described above, according to the present invention, the leachate purification device has a simple structure, which reduces installation and operating costs, and provides leachate purification device equipped with the burying facility itself so as to quickly adsorb leachate such as wastewater generated in the landfill layer. It can be discharged by purifying treatment and leachate does not flow between vertical order wall and leachate purification device by projecting jaw formed on the outer wall part, so that the soil or river around landfill facility can be contaminated by flooding or spillage of leachate. It has an effect.
