摘要
介绍了采用水解酸化/生物接触氧化工艺处理印染废水的应用实例。运行结果表明,该工艺能有效去除废水中的污染物,当进水CODCr为1025mg/L、BOD5为343mg/L、SS为421mg/L、色度为500倍时,处理后出水CODCr、BOD5、SS分别可达到43、16、32mg/L,色度可降低到19倍,去除率分别为95.8%、95.3%、92.4%、96.2%。经该工艺处理后的出水水质稳定,并达到了《污水综合排放标准》(GB8978—1996)一级标准。
The design and performance for dyeing wastewater treatment with hydrolytic acidification and bio-contact oxidation are discussed.The performance indicates that the removals of COD,BOD,SS and chroma can reach 95.8%,95.3%,92.4%,and 96.2% respectively,when the influent concentrations of COD,BOD,SS and chroma are 1 025,343,421 mg/L and 500 times.And the effluent concentrations of COD,BOD,SS and chroma are 43,16,32 mg/L and 19 times,respectively.The water quanlity of effluent is stable and the effluent can achieve first class of Integrated Wastewater Discharge Standard（GB 8978—1996）.
