摘　　要：通过检测某再生水厂生活出水中的氨氮和总氮含量,分析了氨氮和总氮含量之间的相关性.结果表明,再生水中氨氮和总氮两个监测因子之间的相关关系为：秋季最好,R为0.992 5;冬季其次,R为0.934 6;最后是春季和夏季,R分别为0.777 0和0.725 7.氨氮和总氮含量之间的比例系数为0.010～0.310,波动较大,根据各不同季节氨氮和总氮的比例系数K季均值,可以得到氨氮和总氮含量的比例系数K年均值为0.078.The relativity of ammonia nitrogen （NH3 - N） and total nitrogen （TN） was analyzed according to the amount of NH3 - N and TN detected in domestic effluent of reclaimed water plant. The results indicated there were strong relationships between NH3 - N and TN in the reclaimed water in autumn and winter, which R were 0. 992 5 and 0. 934 6, respectively, and there were little weaker in spring and summer, which R were 0.777 0 and 0.725 7, respectively. The ratio coefficients K between NH3 - N and TN were from 0.010 to 0.310 which there was a wide range. The K of annual average value （Kaav） of NH3 -N and TN was 0. 078 calculated by the K of seasonal average value （Ksav ） of in different seasons.
