主要采用阳离子聚丙烯酰胺( CPAM)联合絮凝剂聚合硫酸铁( PFS)对直接染料废水的脱色效果及COD去除率进行了处理及测定,并分别对PFS、CPAM单独使用的效果与CPAM联合PFS使用的效果进行了比较。实验结果表明：CPAM联合PFS使用的效果明显高于PFS、CPAM单独使用的效果。 CPAM联合PFS使用时在室温条件下,废水pH=8时,PFS絮凝剂的投加量为100mg·L-1, CPAM助凝剂的投加量为5mg·L-1时,脱色效果是最佳的,脱色率可达95%以上,其COD的去除率是最好的,可达80%以上。

This experiment mainly adopts cationic polyacrylamide ( CPAM) combined flocculant PFS decolorization to process and meas-ure decolorization effect of the direct dye wastewater and COD removal rate, and makes a comparison between the effect of using PFS and CPAM alone and the effect of using CPAM combined with PFS. Experimental results show that:the effect of using CPAM combined with PFS is significantly better than the effect of the effect of using PFS and CPAM alone. If CPAM combined with PFS is used under the con-dition of room temperature, when pH = 8, PFS flocculant dosage is 100mg·L-1 and CPAM coagulant dosage is 5mg·L-1 , decolori-zing effect is the best with the decolorization rate up to over 95%, and the removal rate of COD is the best, up to over 80%.
