Abstract

본 발명은 환경오염의 주요인인 분뇨나 기타 고농도 유기오수를 액상 부식법으로 응집, 고액분리처리 함에 있어서, 응집시 사용되는 염화제2철을 40-80%로 하고 이에 60-20%의 염산을 첨가 혼합한 혼합액을 응집제로 사용하므로서 염화제2철의 사용을 저감시키며, 중금속의 오염을 크게 저감시키면서 방류를 원활하게 할수 있도록한 액상부식법에 있어서의 염화 제2철 저감 방법에 관한 것이다.In the present invention, in the process of flocculation and solid-liquid separation of manure or other high-concentration organic sewage, which is a major cause of environmental pollution, the ferric chloride used for flocculation is 40-80% and 60-20% hydrochloric acid is used. The present invention relates to a method for reducing ferric chloride in a liquid corrosion method in which the use of the mixed solution mixed with an additive as a coagulant reduces the use of ferric chloride and facilitates the discharge while greatly reducing the contamination of heavy metals.
