본 발명은 쓰레기 매립장의 오염 폐수 처리장치에 관한 것으로서, 더욱 상세 하게는, 쓰레기 매립장 내에서 발생하는 오염된 침출수를 분리 배출하여 정화한 후 매립지 주변 식생물에 공급하도록 한 쓰레기 매립장의 오염 폐수 처리장치에 관한 것이다.The present invention relates to an apparatus for treating contaminated wastewater in a landfill, and more particularly, an apparatus for treating contaminated wastewater in a landfill for discharging and discharging contaminated leachate generated in a landfill and supplying it to vegetation surrounding the landfill. It is about.

국내에서는 일반적으로 발생하는 생활쓰레기의 대부분을 매립지에 매립하는 방법으로 처리하는데, 매립지에서 발생하는 오염 폐수 즉, 침출수에는 유기물질과 암모니아성 질소가 고농도로 혼합되어 있으므로 이를 그대로 유출할 경우에는 지하수 등이 오염되며, 따라서 침출수를 정화 처리하여 배출하는 것이 바람직하다.In Korea, most of the household waste generated generally is disposed of in landfills. Contaminated wastewater generated from landfills, that is, leachate, contains a high concentration of organic substances and ammonia nitrogen. This is contaminated, and therefore, it is desirable to purify and discharge the leachate.

국내 생활쓰레기 매립지에서 발생하는 침출수에는 중금속과 인화합물의 농도는 낮고 유기물질 및 암모니아성질소의 농도는 높게 구성되어 있으므로, 일반적인 정화 처리방법으로는 적정한 처리가 어려운 실정이다. 특히, 국내 매립장에서 발생하는 생활쓰레기의 침출수를 외국의 쓰레기 매립지의 침출수와 비교해 볼 때, 양이 많고 그 조성물의 성분도 판이하게 달라서 외국에서 사용하는 침출수 정화처리공정을 적용하여 실시하더라도 정화처리 능률과 효율이 현저하게 떨어지게 되고, 우리나라와 생활문화가 비슷하여 생활쓰레기침출수의 성상이 가장 유사할 것으로 생각되어지는 일본의 경우에는 쓰레기를 소각의 방법으로 처리하므로 매립에 따른 침출수 처리공정을 두지 않고 있다. 또한, 침출수는 매립기간이 경과함에 따라 침출수에 함유된 오염성분이 변화하게 되므로 기존의 단일 처리공정에 따른 처리 방법은 많은 문제점이 노출되었다. 따라서 국내 생활쓰레기에 적합한 별개의 침출수의 정화처리하여 재활용하는 장치를 절실히 필요로 하고 있는 실정이다.Leachate generated from domestic garbage landfill is composed of low concentrations of heavy metals and phosphorus compounds and high concentrations of organic substances and ammonia nitrogen. In particular, when comparing the leachate of domestic garbage generated in domestic landfills with that of foreign landfills, the amount of the leachate from the landfills of foreign lands is different and the composition of the composition is very different. In Japan, where the efficiency is markedly reduced and the living culture of leachate is considered to be the most similar because of the similar life culture with Korea, wastes are treated by incineration, so there is no leachate treatment process due to landfill. In addition, the leachate has a lot of problems exposed to the conventional treatment method according to the single treatment process because the contaminant contained in the leachate changes as the landfill period elapses. Therefore, there is an urgent need for a device for the purification and recycling of separate leachate suitable for domestic garbage.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위한 것으로써, 본 발명의 목적은 쓰레기 매립장 내에서 발생하는 오염된 침출수를 분리 배출하여 정화한 후 매립지 주변 식생물에 공급하도록 한 쓰레기 매립장의 오염 폐수 처리장치를 제공하는 데 있다.Therefore, the present invention is to solve the above problems, an object of the present invention is to separate and discharge the contaminated leachate generated in the landfill and to purify the waste landfill waste landfill to supply to the vegetation surrounding the landfill To provide a processing device.
