| 摘 要： | 针对受毒死蜱污染的原水,通过小试研究了粉末活性炭(PAC)吸附强化聚合氯化铝混凝工艺对毒死蜱的去除效果。结果表明,单独投加8mg/L聚合氯化铝和0.05mg/LPAM难以将毒死蜱浓度降低至《生活饮用水卫生标准》的限值(0.03mg/L)要求,需要采用PAC吸附与混凝沉淀联用工艺。当原水毒死蜱浓度超标5,10,20,30,40和50倍时,所对应的粉末活性炭最佳投加量分别为20,30,30,40,40和50mg/L,出水浓度均小于0.03mg/L。PAC吸附强化工艺聚合氯化铝混凝工艺可有效应对原水的毒死蜱污染,保障供水安全。

| Abstract: | A lab test was carried out to investigate the removal of chlorpyrifos in the raw water by using powder activated carbon (PAC) adsorption enhanced polyaluminium chloride coagulation.The results indicated that it was difficult to reduce the concentration of chlorpyrifos to the required value (0.03 mg/L)in the Standards for Drinking Water Quality by only dosing 8 mg/L polyaluminium chloride and 0.05 mg/L PAM,and combination process of PAC adsorption and coagulation sedimentation would be needed.The concentrati... |
