Abstract

본 발명은 하수, 분뇨 등의 오수처리에 있어서, 탈수공정에서 철계의 염화물 및 황산염으로 이루어진 응집제 용액(1)과 여과보조제로서 탄산칼슘을 배합시킨 소석희 유화액(4)을 첨가하여 악취 발생을 방지하는 방법에 관한 것이다.In the sewage treatment of sewage and manure, the present invention adds a coagulant solution (1) consisting of iron chlorides and sulfates in a dehydration step and a Soseokhee emulsion (4) containing calcium carbonate as a filter aid to prevent odors. It is about how to.

현재 사용되고 있는 가압탈수 설비를 그대로 사용하여 오니 및 탈수 케이크로부터 악취물질이 발생하는 것을 효과적이고도 지속적으로 방지할 수 있다.It is possible to effectively and continuously prevent the generation of odorous substances from sludge and dewatering cake by using the pressurized dehydration equipment currently used.
