Abstract

본 발명은 무기성 슬러지(Inorganic Sludge) 매립처분장의 침출수 처리방법, 특히,소규모 무기성 슬러지 매립 처분장의 저농도 오염물질 함유 침출수 처리 방법에 관한 것이다. 본 발명에 의하여 하루 침출수 발생량이 3000㎥ 미만이고 COD 농도가 100-300ppm인 무기성 슬러지 매립처분방으로부터의 침출수를 조정조에 유입 후 반응조(약품조)를 통해 처리하는 방법에 있어서, FeCl3, FeCl2, FeSO4, 및 그 혼합물로 구성된 군으로부터 선택된 철화합물을 침출수 기준 100ppm 이상으로 반응조에 투입하고 pH조절제(산 또는 염기)를 사용하여 반응액의 pH를 5.6∼8.6으로 조절하여 20-60분간 반응시킨 후 고분자 응집제를 투입하여 반응물을 응집시키고, 결과의 혼합물을 참전조에 유입시켜 고액을 분리시킨 다음 상등액을 모래여과기(S/F)를 통해 여과시키는 것을 특징으로 하는, 무기성 슬러지 매립 처분장의 침출수 처리방법이 제공된다.The present invention relates to a method for treating leachate in an inorganic sludge landfill, particularly a method for treating leachate containing low concentrations of contaminants in a small inorganic sludge landfill. In the method for treating leachate from an inorganic sludge landfill having a daily leachate less than 3000m 3 and a COD concentration of 100-300ppm according to the present invention into a control tank and then treating it through a reaction tank (chemical bath), FeCl 3 , FeCl Iron compound selected from the group consisting of 2 , FeSO 4 , and mixtures thereof was introduced into the reactor at 100 ppm or more based on the leachate, and the pH of the reaction solution was adjusted to 5.6-8.6 using a pH adjuster (acid or base) for 20-60 minutes. After the reaction, a polymer flocculant is added to agglomerate the reactants, and the resulting mixture is introduced into a war vessel to separate the solid solution, and then the supernatant is filtered through a sand filter (S / F). Leachate treatment methods are provided.
