Abstract
본 발명은 무기성 슬러지 매립처분장의 침출수를 처리하는 방법에 관한 것이다. 이 방법은 침출수내의 COD 원인 물질을 철염계 약품과 반응시켜 착물을 형성시키고, 그 반응물을 고분자 응집제로 침출수를 여과시킨 후 염소제 산화제로 산화처리하고, 이어서 산화처리된 침출수를 pH 5.8-8.5되게 조정하여 방출시킴을 포함한다.The present invention relates to a method for treating leachate of an inorganic sludge landfill. This method reacts COD-causing substances in leachate with iron salt-based chemicals to form a complex, leaches the leachate with a polymer flocculant, and then oxidizes it with a chlorine oxidant, and then oxidizes the leached leachate to pH 5.8-8.5. Adjusted release.
