摘　　要：文章对高浓度氨氮废水进行试验研究,提出采用折点氯化法的改进方法—使用漂白粉处理二沉池出水,向烧杯中投加一定量的漂白粉,开启磁力搅拌器搅拌,在反应60、120分钟时取水样,小试二沉池出水氨氮去除效果,探讨总排水氨氮达标方案。经过试验处理后,氨氮的去除率能达到80%,该试验具有一定的中试试验及工程应用价值。The article study on the high concentration of ammonia nitrogen wastewater, an improved method of break point chlorination process is presented in this article-use bleaching powder processing the second pond water, add a certain amount of bleaching powder to the beaker, open magnetic stirrer stirring, water sampling in the reaction of 60, 120 minutes, test the secondary clarifier effluent ammonia nitrogen removal rate and explore the total drainage of ammonia project. After experimental treatment, ammonia nitrogen removal rate can reach 80 %, which has certain value in pilot testing and its application in engineering.
