摘要
通过抽样、调研和取样监测,得到了各季节上海市人均自来水用量和居民生活污水主要污染物浓度的数据,计算出各季节上海市居民生活用水主要污染物产生系数.结果表明,COD产生系数在冬季最高,夏季与春(秋)季较为接近.氨氮、总氮、总磷则是冬季和春(秋)季较为接近,夏季较低.全年平均COD、氨氮、总氮、总磷产生系数分别为54.5,6.4,8.8,0.7g/(人·d).上海市各区按照单位面积居民生活用水主要污染物负荷数值大小划分为4个层次,根据所在层次可采用密集管道集中收集,分片收集,小规模生态处理等污染物削减方案.
The real data of on-site water consumption per capita and concentration of major pollutants in Shanghai were assayed.The highest coefficient of produced COD was in winter,the coefficient in summer was close to spring and autumn.The lowest coefficients of produced NH4＋-N,TN,TP was in summer,the coefficients in winter was close to spring and autumn.Then the coefficients of produced COD,NH4＋-N,TN and TP were 54.5,6.4,8.8,0.7g/（person·d）,respectively.According to the pollutants discharge load of per unit area,the districts of Shanghai could be divided into four levels.Different mitigation schemes were suggested according to the discharge load.
