KDF滤池去除微污染原水中的铅和汞

KDF Filter for Removing Lead and Mercury from Micro-polluted Raw Water

重金属是微污染源水中的污染物之一,采用常规工艺处理时出水水质往往难以达到要求。以KDF为滤料,研究了接触反应时间、滤层高度和滤速对铅和汞去除效果的影响。结果表明,选择合理的接触反应时间、滤层高度和滤速能有效去除微污染原水中的铅和汞。

Heavy metal was one of the pollutants in micro-polluted source water,and it was difficult to satisfy requirement for the finished water quality by using conventional treatment process.In the KDF filter,effect of contact reaction time,filter bed height,and filtering velocity on lead and mercury removal was studied.The result shows that selection of suitable contact reaction time,filter bed height,and filtering velocity may result in efficient removal of lead and mercury.
