微污染水源水处理技术研究进展

Research on Treatment Technology of Micro-polluted Water Source

以微量有机物,氨氮污染为主要特征的微污染水源水给常规水处理工艺提出了挑战。常规水处理工艺对此类水源水的处理效果很差,难以达到国家的饮用水标准。通过对多种水处理技术包括强化常规处理技术,化学及生物预处理,高级氧化、吸附和膜处理技术等在微污染水源水处理中的原理、作用及优缺点等进行了探讨。

Micro - polluted water induced by micro organics and ammonia nitrogen brought forward a challenge to conventional water treatment technology. Conventional water treatment technology has little action on the polluted raw water as the effluent can not meet the Sanitary Standard for Drinking Water. The multiple water treatment technology inelucling enhaneed eonventional water treatment, chemical and biological pretreatment, advanced oxidation, adsorption and membrane ete, with their principle, ac- tion,virtue and flaw was discussed.
