| Abstract: | 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. |
