摘要
高氨氮废水排入水体,特别是流动较缓慢的湖泊、江河、海湾,容易引起水中藻类及其他微生物的大量繁殖,从而导致水体富营养化,因此如何能经济有效地控制高氨氮废水的污染,已经是当前面临的重大课题。文章介绍了高浓度氨氮废水的来源及其危害性,概述了治理高浓度氨氮废水的一些主要物化法,并对这些方法工艺的优缺点做出了分析,最后对今后高氨氮废水的处理技术做出了展望。
The discharge of high ammonia - nitrogen wastewater into the water system, especially lakes, rivers and bays with slow flow, will cause large population of algae and other microorganisms, leading to eutrophication. Therefore, the issue of trea- ting high ammonia - nitrogen wastewater pollution with low - cost and high efficiency becomes important. The sources and dangers of high ammonia - nitrogen wastewater were introduced in this paper, while some main physical - chemical methods for treating high ammonia - nitrogen wastewater were outlined. The advantages and disadvantages of these methods were analyzed. Finally, the prospects of high ammonia - nitrogen wastewater treatment were also presented.
