中文摘要	针对上海市50座城市污水处理厂进水水质,利用实际运行数据,系统分析了水质特征以及有机物、氮、磷和悬浮物之间的概率分布和相关关系。结果表明,上海市污水中BOD5、COD、SS、NH3-N、TN和TP全年浓度分布均呈正偏态分布,月中间值分布范围分别在110~150 mg/L、260~325 mg/L、140~175 mg/L、20~30 mg/L、29~37 mg/L和3~5 mg/L。水质指标BOD5和COD、TN和TP及TN和TP之间存在显著的一元线性相关关系。进水BOD5/COD值分布在0.4~0.6之间的概率为64.6%,表明进水中生化性较好。BOD5/TN分布在4~6之间的概率为35.8%,表明进水反硝化碳源不足。BOD5/TP的平均值为32.6,且大于20的累积概率为84.1%,表明污水在处理中可以满足生物除磷的需求。TN/TP比值范围在1~25,平均值为8.6,且TN/TP>5的概率为88.1,表明进水基本满足微生物生长对氮、磷的需求。; The influents of 50 wastewater treatment plants( WWTP) in Shanghai were investigated to analyze the characteristic of water quality,the probability distribution of the main pollution indicators,and the correlations among the organic matters,suspended solids,nitrogen and phosphorus. The results showed that the trend of BOD5,COD,SS,NH3-N,TN and TP in the influents were in accordance with positively skewed distribution,and the concentrations of BOD5,COD,SS,NH3-N,TN and TP( monthly median) were in the range of 110 ~150 mg / L,260 ~ 325 mg / L,140 ~ 175 mg / L,20 ~ 30 mg / L,29 ~ 37 mg / L and 3 ~ 5 mg / L,respectively.The indicators including BOD5,COD,TN and TP have significant simple linear relationships. The probability distribution of BOD5/ COD ratios between 0. 4 and 0. 6 was 64. 6%,indicating an adequate biodegradation ability of the influents. The probability distribution of BOD5/ TN ratios between 4 and 6 was 35. 8%,which meant that the carbon source was inadequate for denitrification. 84. 1% of the BOD5/ TP ratios were above 20,and the average was 32. 6,which can meet the demand for biological phosphorus removal. The probability distribution of TN / TP ratios was in the range of 1 ~ 25,and the average was 8. 6,and 88. 1% of the values were above 5,indicating that the influents can meet the demands of nitrogen and phosphorus for microbial growth.
