摘　　要：采用一级强化混凝+缺氧水解酸化+生物膜-活性污泥共生系统处理印染废水,考察了该工艺流程和主要技术参数。结果表明,该工艺组合能有效去除印染废水中的COD和色度,当进水COD为900～1300mg·L-1,色度为500～600倍,出水达到COD为85～150mg·L-1,色度为50倍以下,达到纺织染整工业水污染排放标准(GB4287-92)一级标准和渭河水系(陕西段)污水综合排放标准(DB61-224-1996)二级别标准。An enhanced coagulation＋ hypoxia acid hydrolysis＋biofilm-activated sludge symbiosis system was used to treat the dyeing sewage. The results shown that the process can remove color and COD effectively in the dyeing sewage and reduce operating cost of 56.5%. When the sewage COD 800-1 300 mg·L^-1, the color of 500-600, Aider treatment, COD was 95-130 mg ·L^-1, the color was 50 below, which achieved ＂Weihe River Basin water pollution emission standards for industrial enterprises＂ and the first standard of ＂textile industrial pollution discharge standards＂.
