摘　　要：活性染料污水 ,水质复杂、色度深、污染物难于降解。采用单一的混凝法或生化法难以达到排放标准。本研究在活性染料污水混凝法处理的基础上进行光助催化。废水中的有机物在紫外光的作用下有机物发生降解。然后进行生化处理 ,使活性染料废水排放达到国家标准。Wastewater of activity dyes is very complex, colour concentrate, and difficalt degradation. In order to achieve discharge standard, useing method of the unitary mixing coagulation or biochemistry is very difficult. On the base of mixing coagulation treatment, we used photocatalytic oxidation. The organic compounds were degraded under photoirradiation, and then treated by biochemistry. The result will achieve discharge standard.
