Abstract

이 발명은 주로 염색 공장의 전처리 설비한 정련공정에서 배출되는 알카리성 폐수를 약품에 의한 응집, 침전 및 이온교환등의 과정을 거치는 화학적처리와, 여재에 의한 여과, 활성탄 흡착, 마이크로필터를 통한 미립자제거등의 과정을 거치는 물리적 처리를 병행하여 공업용수로 재사용할 수 있게 한 폐수처리 방법 및 그 장치에 관한 것으로, 55∼65℃정도의 정련 폐수를 25∼30℃로 낮추어 교반기로 교반하면서 황산알루미늄과 고분자 응집제를 투입하여 PH를 낮춤과 동시에 부유물질을 제거한 뒤 이의 상등액을 샌드필터, AG-메디아 필터, 코오크스 타워, 다층필터, 카본필터, 이온교환기, 필터하우징을 거치도록 하여 정수하는 특징이 있다.This invention mainly treats alkaline wastewater discharged from the refining process of pretreatment facilities of dyeing plant through chemical coagulation, sedimentation and ion exchange, and filtering by filter media, activated carbon adsorption, and microparticle removal The present invention relates to a wastewater treatment method and apparatus for allowing re-use to industrial water in parallel with physical treatment through a process such as the above. The polymer coagulant is added to lower the pH and remove suspended solids. The supernatant is purified by sand filter, AG-media filter, coke tower, multilayer filter, carbon filter, ion exchanger, filter housing. .
