摘　　要：选用季铵型阳离子脱色剂与硅藻土复配,对印染废水进行深度脱色处理。结果表明,单独使用季铵型阳离子脱色剂和硅藻土处理印染废水时,废水CODCr和色度的脱除效果均不理想。采用季铵型阳离子脱色剂/硅藻土复配处理,可大大降低有机絮凝剂用量,明显提高处理效果。当季铵型阳离子脱色剂和硅藻土的投加量分别为40 mg/L和1.5 g/L时,印染废水的CODCr和色度去除率分别为75.2%和97.8%。The coagulation experiments are carried out on the printing and dyeing wastewater from the secondary biochemical treatment system with quaternary ammonium cationic decolorizing agent and diatomite. The results show that the effluent treatment with the individual flocculant cannot obtain the satisfactory results. The combined use of quaternary ammonium type cationic decolorizing agent and diatomite can reduce the flocculant of CODcr and chromaticity are 75.2% and 97.8% respectively when zing agent and diatomite are 40 mg/L and 1.5 g/L. dosage and improve the treatment efficiency. The removals the dosages of quaternary ammonium type cationic decolorizing agent and diatomite are 40 mg/L and 1.5 g/L.
