摘要
将不同碱化度(B)的聚合氯化铁(PFC)和不同特性黏度(η)的聚环氧氯丙烷胺(EPI-DMA)按照不同的PFC的质量(以Fe计)与EPI-DMA的干重比(P)复配,用于絮凝处理模拟分散黄和活性艳红染料废水。考查了复配絮凝剂的投加方式、P值、η值和B值对脱色效果的影响,探讨了絮凝机理。实验结果表明,在本实验选用的投加方式中,处理分散黄染料废水时,先投加PFC后投加EPI-DMA脱色效果最好;而处理活性艳红染料废水时,先投加EPI-DMA后投加PFC脱色效果最好。复配絮凝剂在高η值(4200mPa.s)、低P值(0.5)和B值(0.3)时脱色效果最佳。
A series of dual-coagulants used for the treatment of synthetic disperse yellow and reactive red dyeing wastewater were prepared with different basicicity （B） of PFC, different intrinsic viscosities （η） of EPI-DMA and different ratios （P） of PFC （by weight of Fe） to dry weight of EPI-DMA. The effects of addition methods of dual-coagulants, P value, η value and B value on coagulation efficiency were studied. The results showed that first adding PFC and second adding EPI-DMA could achieve the max- imum color removal rate for synthetic disperse yellow wastewatcr, whereas the reverse adding order could obtain the best color removal rate for synthetic reactive red wastewater. The coagulant with η of 4 200 mPa·s, P of 0.5 and B of 0.3 gave the highest color removal rate in this study.
