Claims (4)
- 중화조에 투입된 중금속이 다량 함유된 산성폐수를 수산화마그네슘의 첨가 및 공기산화에 의하여 pH 6-8.5가 되도록 중화처리하는 단계(제1단계);제1단계에서 중화처리된 산성폐수를 반응조로 옮기고, 석회류 알칼리제의 첨가 및 공기산화에 의하여 pH 9.5-12가 되도록 처리하는 단계(제2단계); 및제2단계에서 중화처리된 산성폐수를 침전 및 최종방류조로 옮기고, 황산의 첨가에 의하여 pH 5.6-8.5가 되도록 역중화시키는 단계(제3단계)를 포함하는 산성폐수의 처리방법.
- 제 1항에 있어서, 상기 석회류 알칼리제가 생석회, 석회석 또는 소석회에서 선택된 어느 하나인 것을 특징으로 하는 산성폐수의 처리방법.
- 제 2항에 있어서, 상기 제1단계 및 제2단계에서 공기산화가 산성폐수 100 내지 150 ㎥/hr당 80 내지 120 N㎥/hr의 공기를 4 내지 6 kg/㎠의 압력으로 강제로 주입하는 것을 특징으로 하는 산성폐수의 처리방법.
