复合混凝剂处理印染废水的实验研究
The Composite Coagulant Treatment of Printing and Dyeing Wastewater
摘要
Abstract
Polyaluminium chloride (PAC)and PAN-DCD compound with coagulant was used to coagulate solute colloid or suspended particles in dye wastewater from a coloured socks factory.The influence of pH,coagulant dosing quantity, coagulation settling time on the coagulant performance are investigated and the coagulant performance was evaluated by the removal rate of COD and chroma.The results indicate that:compound coagulant in the treatment effect is better than single coagulant;the best operating conditions for compound coagulant to treat the dye wastewater was:compound coagulant dosage 10 mg/L,coagulation settling time 25 minutes,pH=7.In this case,the removal rate of chroma was 97.7%,removal rate of COD was 6 7 .2%.关键词
