摘　　要：为调查城市居民生活排污情况,以天津市为例选取有代表性6个居民小区,开展了用排水量、排水水质调查与监测,分析了典型居民小区用排水量数据及人均生活排污系数。结果显示,市区COD、氨氮、TN、TP的人均生活排污系数分别为22.34~58.20、5.45~9.11、7.43~11.22、0.57~0.97g/d;郊区COD、氨氮、TN、TP的人均生活排污系数分别为13.34~40.04、0.99~8.26、1.33~8.79、0.19~0.87g/d,市区居民小区人均生活排污系数明显高于郊区。同时,采用统计年鉴的水量数据,核定了全市城镇居民人均生活排污系数,COD、氨氮、TN、TP分别为37.68、6.92、8.35、0.76g/d。Six residential areas in Tianjin were selected for investigating urban domestic pollutant discharge coefficients.Water consumption and domestic sewage production,sewage quality were monitored for collecting data of typical residential area meanwhile calculating per capita pollution discharge coefficient.The results showed that per capita pollution discharge coefficient of COD,ammonia nitrogen,TN and TP for urban residents were 22.34-58.20,5.45-9.11,7.43-11.22 and 0.57-0.97 g/d,respectively.Corresponding coefficients for suburban residents were 13.34-40.04,0.99-8.26,1.33-8.79,0.19-0.87 g/d,respectively.The per capita pollution discharge coefficients of urban residents were considerably higher than those of residents in suburban areas.Based on statistical data in statistical yearbook,the average value of per capita pollution discharge coefficient of COD,ammonia nitrogen,TN and TP were37.68,6.92,8.35,0.76 g/d,respectively.
