摘要
采用沉淀-气浮-生化处理-气浮工艺处理洗毛废水,进水COD为6000~43000mg·L-1,处理水量为200m·d-3,COD去除率90%;水力停留时间18h,出水COD小于200mg·L-1,可以达到污水综合排放二级标准(洗毛行业)。
Dissolved air flotation(DAF) - anaerobic-biological contact oxidation process was used to treat the wool scouring manufacturing wastewater. The capacity of system was 200 m^3·d^-1 with COD 6 000-43 000 mg·L^-1. The treated water can reach second grade wastewater discharge standard when HRT is 18 hours.
