超滤-纳滤双膜工艺深度净化饮用水效能试验研究
Experimental study on advanced purification of drinking water by UF?NF membrane process
摘要
Abstract
The UF?NF membrane process was used to study the removal efficiency of various pollutants in advanced purification of filtrated water in waterworks. The results show that the UF?NF membrane has good removal efficiency of various indexes and fluorescent substance. Ultrafiltration process can fully guarantee the stable operation of nanofiltration membrane process. The removal rates of benzene and styrene are from 98.73% to 99.07% and 99.58% to 99.75%, and the average values of effluent are 3.060μg/L and 1.792μg/L. The removal rates of heavy metal zinc and cadmium are from 99.22% to 99.34% and 99.16% to 99.34%, and the average values of effluent are 0.025 mg/L and 0.201μg/L. The contents of constants of pollutants, trace organic, heavy metal compounds are accorded with GB 5749—2006 "standards for drinking water quality". The drinking water quality has been improved significantly, and the safety of residents drinking water has been enhanced and guaranteed.关键词
