摘　　要：为降低处理成本,采用筛选的高效絮凝菌株EW-1与高分子化学絮凝剂复配,对印染废水进行絮凝处理,以提高生物絮凝剂的絮凝效果,并减少化学絮凝剂的用量,减少环境污染。结果表明:使用单一絮凝剂,EW-1、PAC、PAM、PAFC的投加量分别为4,7,3,4mL时絮凝效果最好;EW-1与PAC以体积比1∶2的比例复配,投加量为6mL时,絮凝效果最好,絮凝率为79.5%,COD去除率为40.2%。In order to reduce processing costs,improve the flocculation effect of biological flocculant,reduce the amount of chemical flocculant and decrease the environmental pollution,we selected the high-efficiency flocculant strain EW-1 and the macromolecular chemical flocculant to flocculate the printing and dyeing wastewater.The results showed that the flocculation effect was the best when EW-1,PAC,PAM and PAFC were added at 4,7,3 and 4 mL,respectively.EW-1 and PAC were combined in a ratio of 1 ∶2 by volume.When the dosage was 6 mL,flocculation effect was the best,with a flocculation rate of 79.5% and COD removal rate of 40.2%.
