摘　　要：以二级出水作为唯一补给来源的天津市某景观湖泊(J湖)为例,于不同季节对氨氮(NH_(3)-N)、总氮(TN)、总磷(TP)和化学需氧量(COD)等4个水质指标进行检测分析,并采用单因子污染指数法、内梅罗污染指数法、综合水质标识指数法等3种方法对J湖进行了水质评价.结果表明:J湖的首要优先控制污染物是TN,其次是TP;4个季节均为劣Ⅴ类水体,但春夏季节相对于秋冬季节而言,J湖污染更为严重.最后,基于TN、TP和COD的监测数据与内梅罗污染指数进行多元线性拟合提出了各季度的水污染控制数学模型.Taking a landscape lake(Lake J)in Tianjin only recharged by secondary effluent as an example,four water quality indexes,including ammonia nitrogen(NH_(3)-N),total nitrogen(TN)and total phosphorus(TP),and chemical oxygen demand(COD)were detected and analyzed in different seasons.And the water quality of Lake J was evaluated by three methods,i.e.,single factor evaluation method,Nemerow pollution index method and comprehensive water quality identification index method.The results showed that TN was the first priority pollutant in Lake J,followed by TP.The water quality of Lake J was inferior V level in all four seasons,but lake pollution was more serious in spring and summer rather than autumn and winter.Finally,the mathematical models of water pollution control for each quarter were put forward by multiple linear fitting based on the monitoring data of TN,TP and COD and Nemero pollution index.
