摘　　要：印染废水COD高、色度高、可生化性差,是较难处理的工业废水。采用水解酸化-接触氧化-混凝工艺处理印染废水,COD、BOD、SS和色度去除率分别达到86%、92.5%、88%、90%。印染废水处理后达到《纺织染整工业水污染物排放标准》(GB4287-92)1级排放标准。此工艺具有工程投资少、运行稳定、处理效果好等优点。The dyeing wastewater is a kind of industrial wastewater which is hard to be treated, with high COD, high daroma and low biochemistry. Hydrolytic acidification- contact oxidation - coagulation process is adopted to treat dyeing wastewater and the removal rates of COD, BOD, SS and chroma can reach 86%, 92.5%, 88% and 90% respectively. The effluent can reach the first grade discharge standard of ＂Water PoUutants for Dyeing and Finishing of Textile Industry＂ （GB4287 - 92）. It has advantages d low engineering investment, stable operation and high efficiency, etc.
