摘要：印染废水有机污染物浓度高、可生化性差、色度深，处理难度大。本实验以CODCr和色度为指标，对取自某拉链厂的印染废水进行混凝实验，通过最佳投药量和最佳pH实验，比较了聚合硫酸铁、硫酸铁和硫酸铝三种絮凝剂的混凝效果，及PFS和PAM的最佳复配比。实验结果表明，聚合硫酸铁的混凝效果优于硫酸铁和精制硫酸铝，CODCr去除率可达80%以上。当PFS/PAM=2.5时，复配效果较好。本实验为今后相关实验提供科学的数据参考，并为印染厂的废水治理提供技术参数的参考，以期提高污水后期处理的可生化性，降低企业污水处理费用的投入，减轻对环境的污染程度。 |

Abstract: Dyeing effluent discharged contains high concentration of organic pollutant, showing poor biodegradability, deep chromaticity and the difficulty to be treated. In this study, dyeing wastewater discharged from certain slide fastener plant was collected to implement coagu-flocculation experiment under indicators of CODcr and chromar. Through dosage of coagulant and pH optimized, flocculation effects of Polymeric Ferric Sulfate（PFS）, Ferric Sulfate and Aluminium Sulfate were obtained, as well as the optimum ratio of PFS to PAM. The result showed that flocculation effects of PFS predominated over counterparts, with the removal efficiency of CODcr of 80% above. When PFS/PAM was 2.5, combinational effect reached the better case. This study provided the following relative experiment with scientific data reference, and wastewater treatment of printing and dyeing mill with technical parameters reference. We expect that biodegradability of discharge can be improved during post-treatment; cost for sewage treatment is in reduction; the level of environmental pollution decreases. keywords: Polymeric Ferric Sulfate(PFS); slide fastener plant; flocculate; printing and dyeing mill |
