In view of the fact that the drinking water in coastal cities is affected by salt tide, the feasibility of the technologies for emergency treatment of sudden water pollution accident caused by heavy metals as well as the influence of high salinity on those technologies were discussed. The test results showed that, the lead,cadmium and nickel which caused the sudden water pollution accident could be effectively removed through adjusting pH value and enhancing coagulation; and the sudden water pollution of chromium and arsenic could be effectively controlled by Fe2+ reduction-molysite coagulation precipitation process and NaClO oxidation-molysite coagulation precipitation process respectively. It could be seen that, high salinity had little influence on the technologies for emergency treatment of sudden water pollution accident caused by heavy metals.%针对沿海城市饮用水受咸潮影响的实际情况,探讨突发重金属污染的应急处理技术的可行性及高盐度对该技术的影响,试验结果表明,调节pH值-强化混凝可以有效控制突发的铅、镉、镍污染;亚铁还原(六价铬为三价铬)-铁盐混凝法可以有效控制突发的铬污染;NaClO氧化(三价砷为五价砷)-铁盐混凝法可以有效控制突发的砷污染;高盐度对突发重金属污染应急处理技术的影响很小.
