混凝去除污水中百菌清的研究

摘要

研究了模拟污水中百菌清污染的混凝处理措施.试验对比了三种混凝剂(聚合氯化铝、硫酸铝、三氯化铁)的反应效果,结果表明聚合氯化铝对去除百菌清有明显的优势,投加量在150 mg/L时,污水中百菌清的去除率为85.39％,COD的去除率为34.60％,浊度的去除率为87.01％.通过投加助凝剂只能改善浊度的去除效果,对百菌清和COD的去除影响不是很大.%In this paper, the effects of chlorothalonil removal by coagulation under simulated conditions were studied. By comparing the reaction effect of three coagulants (aluminum chloride, aluminum sulfate, ferric chloride) , the results showed that polyaluminum chloride has obvious advantages on the removal of chlorothalonil, With 150 mg/L dosing quantity of PAC, the removal rate of chlorothalonil could be up to 85. 39% , the removal rate of COD was 34. 60% , the removal rate of turbidity was 87. 01%. It could only improve the turbidity removal efficiency ,but the impact of chlorothalonil and COD is not great by adding coagulant.
