摘要
采用混凝+水解酸化+推流式接触氧化+混凝(C-HC-PBCO-C)处理针织印染废水,结果表明,此工艺能有效去除废水中污染物,出水平均CODCr、BOD5、SS和色度分别为77 mg/L、13 mg/L、35 mg/L和30倍,出水水质达到广东省DB44/26—2001《水污染排放限值》第Ⅱ时段一级排放标准。
Wastewater treatment in dyeing mills is carried out by coagulation-hydrolysis acidification-plugflow biological contact oxidation-coagulation （C-HC-PBCO-C） process,The results show that this system has high efficiency in pollutants removal. The average concentration of CODCr, BOD5, SS, and chromaticity of the water outlets are 77 mg/L, 13 mg/L, 35 mg/L and 30 times respectively. All indications of the water outlets can meet the first level of ＂ Discharge Limits of Water Pollutants＂ （ DB44/26-2001 ）.
