氮、磷的存在通常被认为会造成水质的富营养化。氨氮在地表水中如果较高，会导致对水生生物有毒，主要是由于水中非离子氨（NH3）造成的。本文结合贵州铝厂在污水零排放前后的水质情况，主要分析了二次利用水中氨氮和磷的主要去除途径、原理及氮、磷走势对二次利用水系统的影响。%The presence of nitrogen and phosphorus is generally believed to result in the eutrophication of water quality. In the surface water if there is a higher ammonia nitrogen, can cause toxic to aquatic organisms, toxicity is mainly caused by the water ammonia(NH3). In this paper, combining with the development of Guizhou aluminum plant in before and after the zero discharge of sewage water quality, the main analysis of the reclaimed water ammonia nitrogen and phosphorus mainly removal approach, principle of nitrogen and phosphorus, and the trend of reclaimed water system influence.
