| 摘 要： | 以高锰酸盐指数（CODMn)和Ames试验为评价指标,研究了反渗透为主的组合工艺对自来水中致突变性有机物的去除效果。试验表明,组合工艺中的活性炭单元可以去除自来水中约50％的有机污染物,但对自来水的致突变性没有明显改善;反渗透膜单元能达到同时去除有机污染物和改善自来水致突变性的效果。此工艺是获得安全优质饮用水的一种可行办法。

| Abstract: | Using COD Mn and Ames test as evaluation index, the reverse osmosis based process for drinking water treatment was studied on removal of mutagenic organic pollutants from tap water. The study results show that the activated carbon unit in the process can remove about 50% of organic pollutants, but the attenuation of tap water mutagenicity is poor. The reverse osmosis unit can remove organic pollutants and attenuate mutagenicity simultaneously. This combined process is feasible for providing safe potable water with good quality. |
