摘　　要：选择絮凝剂聚合氯化铝(PAC)为研究对象,研究了通过絮凝及降解作用去除水环境中的亚硝基氮、氨氮、总凯氏氮的规律和效果,并确定了絮凝沉淀的最佳工艺参数。研究结果表明,当PAC的投加量为40mg/L时,硝基氮的去除率达到30.71%,亚硝基氮的去除率为77.27%,氨氮的去除率为37.5%,总氮(TKN)的去除率为40%。This paper mainly choose the flocculating agent polyaluminium chloride （PAC） as the research object, through the flocculation of nitrocellulose nitrogen, nitroso nitrogen, ammonia nitrogen, total kjeldahl nitrogen in water supply, and determine the optimal flocculation scheme. The researches of the experimental results show that while the concentration of PAC reached 40mg/L, the corresponding removal value of nitrate reaches 30.71%, the corresponding removal rate of nitrite is 77.27%, the removal of ammonia nitrogen is 37.5%, and the removal rate of TKN is 40%.
