| 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。

| Abstract: | 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 d... |
