微污染水源水中氨氮的危害与现代处理技术

Hazards and modern treatment technologies of ammonia nitrogen in slightly polluted water source water

在我国微污染水源水中,氨氮污染问题尤为突出,而目前自来水厂大多采用传统工艺,主要针对悬浮物、细菌和病毒,对氨氮的去除效果差,所以必须进行工艺改造。针对我国的微污染水源水中氨氮的污染现状,对当下去除微污染水源水中氨氮的常见物化法、生物法和联合处理法进行综述,介绍了它们的原理和优缺点,并对未来微污染水源中氨氮的去除技术进行了展望。

In China,the ammonia nitrogen pollution problems in slightly polluted water source water are especially prominent. At present,traditional technologies have been used in most waterworks. It is necessary to implement technological transform,because of the poor ammonium nitrogen removing effect caused by SS,bacteria,virus. Aiming at the current pollution status of ammonia nitrogen in slightly polluted water source water in China,the common physical method,biological method and combined treatment method for removing ammonia nitrogen from slightly pollution water source water are summarized. Their principles,advantages and disadvantages are introduced and the technologies of removing ammonium nitrogen from slightly polluted water sources in the future predicted.
