摘　　要：印染废水是纺织工业污染的主要来源,其中的多种染料和化学助剂属于难降解有机物,采用常规生物方法难以达标处理.向混凝沉淀SBR复合工艺系统中添加多菌种高效菌剂,生物强化处理COD约900mg.L-1印染废水,取得了理想的效果.废水中各项污染指标均达到排放标准,其中出水平均COD达到91mg.L-1,去除率为89.6%.证明多菌种生物强化SBR工艺处理纺织印染废水是可行的.Printing and dyeing wastewater is the main source of textile industrial pollution, since a variety of dyes and chemical agents are organic matter which is difficult to degrade, and thus the conventional biological treatment makes it difficult to attain a designated standard. In this paper, by adding high effective multi-strain microbe to coagulation-sedimentation and SBR process composite system, it was found that bioaugmentation enhanced the treatment of printing and dyeing wastewater with a COD about 900 mg · L^-1 and achieved the desired results. In the waste water each contamination index achieved the discharge standard, in which the average effluent COD reached 91 mg · L^-1 and the removal rate was 89. 6%. The study shows that multi-strain bioaugmentation SBR process is feasible and effective in treating textile-dyeing wastewater.
