摘　　要：溴氰菊酯是净水厂原水突发水质污染的高风险物质之一。通过中试研究了原水突发溴氰菊酯污染的应急处理工艺。结果表明,仅靠常规工艺难以有效应对原水突发溴氰菊酯污染;向原水中投加粉末活性炭(PAC)与强化常规处理工艺联用可有效去除水中溴氰菊酯,保证处理后水质达到生活饮用水卫生标准要求;炭液混合和混凝澄清阶段是溴氰菊酯去除的主要阶段,去除率为42%～98%;炭砂滤柱通过吸附截留水中载有溴氰菊酯的微小絮体颗粒,实现进一步去除水中溴氰菊酯的目的;颗粒炭滤柱作为安全余量,是水质安全保障的最后关口。基于中试结果,给出了应对原水突发溴氰菊酯污染时PAC对溴氰菊酯的吸附能力。Deltamethrin is a highly risky matter in sudden raw water pollution for waterworks.This paper studied the emergency process against the deltamethrin pollution in raw water by pilot experiment.The results showed：it was difficult for the conventional process to cope with the sudden raw water deltamethrin pollution effectively;combination of powered activated carbon（PAC）with enhanced conventional process could remove deltamethrin in water effectively and make the produced water meet the sanitary standard for drinking water;the mixture of PAC and water and the coagulation clarification were the key processes to remove deltamethrin,and the removal efficiency of them could reach 42%~98%;carbon-sand filter column could intercept the micro flcos and particles carrying deltamethrin in water and reduce the deltamethrin further;as a safe clearance,granual activated carbon filter column was the last process for water quality security.Based on the pilot experiment,the absorption ability of PAC to deltamethrin in respond-ing to the sudden raw water deltamethrin pollution was determined.
