饮用水原水微污染及其处理技术

Light-pollution of Raw Drinking Water and Its Control

水环境污染造成的饮用水原水水质下降及传统给水处理工艺的缺陷导致饮用水中含有ＴＨＭｓ，ＭＸ等（可疑）致癌物及其它有机物，严重威胁人体健康。水处理工作者对传统工艺进行了诸多改进，并开发了种类繁多的新型物理、化学技术及生物预处理技术。本文对三者进行了系统的总结，并重点分析了后者，认为：生物预处理技术在成本上能够为我国大部分地区所接受，毒理学安全，见效快，它与改进后的传统工艺的联用应成为国内水厂改善出水水质的首选方法。

The deterioration of raw water quality caused by water pollution and the deficiency of conventional water treatment technique results in the drinking water containing THMs, MX and other organic pollutants which seriously threaten human health Scientists and engineers have improved the conventional technique in several aspects, developed many physical, chemical techniques and biological pretreatment processes This article systematically analyses these three, and more attention is focused on the third It is concluded that biological pretreatment can be accepted by most areas of China in cost, and this process is also eco-toxicologically safe, the combination of it and improved conventional technique should be the top priority for China’s water treatment plants to better the drinking water quality
