逆渗透组合工艺去除自来水中重金属及放射性核素

Removal of Heavy Metals and Radionuclides in Tap Water with Combined Processes of RO and AC Filtration

本文研究表明微滤及活性炭均不能有效去除自来水中无机微污染物 ,而逆渗透技术对有毒重金属元素及放射性核素的去除率分别高达 95 %与 99%以上 ,经逆渗透处理后的自来水可达到很高品质。

In this paper, the results showed that both microfiltration and activated carbon could not remove significantly the inorganic pollutants in the tap water, but the reverse osmosis technique could remove the poisonous metals and redionuclides by more than 95% and 99%, respectively and thus the treated water was one of superior quality. It is believed that this technique will be useful for the advanced treatment for the tap water in the area where the source water is heavily polluted by heavy metals and radionuclides.
