摘　　要：通过对浙江省某分散染料厂车间内的各个生产工艺流程的水质水量进行分析,以及对不同的水质进行单独处理和研究,提出了"分质物化预处理+综合水解,厌氧、好氧生化处理+后道物化处理"的改造工艺。通过利用微电解和芬顿处理、高效厌氧反应器、生物接触氧化和移动式生物床反应器等技术,使改造后的废水出水实现达标排放,COD(化学需氧量)去除率大于95%,色度去除率大于90%。该废水处理改造工程运行1年,效果稳定。Through the analysis of water quality and water quantity of each process in a disperse dye factory of Zhejiang province, and the separative treatment and study of different water qualities, the reform process of＂source-separated physicochemical pretreatment ＋ hydrolysis, anaerobic, aerobic biochemical treatment ＋after physicochemical treatment＂was put forward. By using micro electrolysis and Fenton technology, high efficiency anaerobic reactor, biological contact oxidation technology and mobile biological bed reactor technology, the treated wastewater could achieve discharge standards,the COD（Chemical Oxygen Demand） removal rate reached more than 95%, and the chroma removal rate reached more than 90%. The wastewater treatment renovation project has run for more than 1 year, and its effect is stable.
