氨氮污染是导致江河湖泊水体富营养化的主要因素.从全国范围来看,主要水体的污染有逐年加重的趋势.能否有效地控制点源和面源氮素污染,已经成为遏制目前水体污染加剧形势的关键所在.近年来对氨氮控制的研究很多,但是利用自然基质碳源对氨氮脱除的研究却极少.本文介绍了氨氮污染的现状,探讨了目前各类脱氮技术的优缺点及未来脱氮技术的发展方向.

Ammonia pollution was a major factor leading to eutrophication of rivers and lakes. Nationwide, water pollution deteriorated year by year. Ability to effectively control point source and non-point source nitrogen pollution had become the key point of water pollution control. In recent years, there had been many studies on ammonia control, but research on the use of natural carbon matrix in the removal of ammonia was rare. This paper introduced the current status of ammonia pollution, and discussed the current advantages and disadvantages of various types of denitrification technology and the future direction of denitrification technology.
