Abstract:
Aiming at the characteristics of lowbiodegradability and high chroma of bleaching and dyeing wastewater,the hydrolysis acidification- contact oxidation-coagulation sedimentation process has been used. The running results show that:the indexes of CODCr,BOD5 ,chrom a,SS,pH, etc. in the effluent water meet the requirements of the first class Integrated Wastewater Discharge Standard(GB 8978—1996).

摘要：
针对漂染废水色度高、可生化性差的特点,工程上采用水解酸化—接触氧化—混凝沉淀的处理工艺。运行结果表明,经上述工艺处理后的出水CODCr、BOD5、色度、SS、pH等指标均能达到GB8978—1996《污水综合排放标准》一级标准。
