摘　　要：选取江苏科技大学一村居民小区为研究区域,通过对生活污水排放量、pH、COD、NH3-N和TP的监测,研究了生活污水的排放特征和水质水量的变化规律,及与气候、居民生活方式间的关系,为城市管网系统的改造提供依据.结果表明:生活污水流量和COD值在6∶00,12∶00,20∶00达峰值,12∶00达最高峰,COD为267～336 mg/L;NH3-N和TP的浓度在凌晨时段较低,8∶00达到最大值,分别为37.83 mg/L和5.52 mg/L,之后逐渐降低趋于平稳;生活污水流量的月平均值有明显差异,与气候的变化呈现出了良好的正相关性;COD,NH3-N,TP三者均表现出夏季浓度较低,冬季浓度较高的规律.In order to evaluate pollut：ion condition of domestic wastewater in Zhenjiang city, the first village of Jiangsu University of Science and Technology is investigated. Characteristic indices of domestic wastewater, in- eluding wastewater flow rate, pH, COD, NH3-N and TP of domestic wastewater, are monitored. The results show that the wastewater flow rate and COD concentration chang over time with a general identical tendency in a whole day. COD concentration reaches the peak at 12： 00 AM 1 with 267 - 336 mg/L, and concentrations of NH3-N and TP reaches the peak at 8：00 AM with 37.83 mg/L and 5.52 mg/L respectively, then gradually re- duces. Daily average of wastewater flow rate varies significantly in the study period, and the concentrations of indices including COD, NH3-N and TP have an obvious change with season, namely lower in summer and higher in winter.
