摘要
为给镇江市合流制污水管网(简称合流管网)系统的改造提供参考依据,选择镇江市内一条具有代表性的合流管网,并从2010年7月至2011年3月(2月除外,4次/周)对管网中5个采样点的生活污水水质进行旱天监测。结果表明,生活污水中COD、SS、TP、NH3-N浓度在不同月份之间具有明显的变化差异,并且波动幅度较大,冬、春季生活污水中COD浓度皆高于夏、秋季;居民混合区排出的生活污水中污染物浓度显著高于其他4个采样点。
Five sampling sites in typical combined pipe network of Zhenjiang were selected as sampling sites to monitor the water quality of discharged sewage from July 2010 to March 20ll （four weeks a month and four times a week）. The sewage emission rule of the typical combined sewer system in dry days was studied,which would provide reference for combined sewer pipe network reconstruction in Zhenjiang. The results indicated that COD, SS, TP, NH3-N had obvious spatio-temporal variation characteristics lthe monthly variation of these pollutants presented a rel- atively large fluctuation; the concentration of sewage COD in winter and spring was higher than that in summer and autumn; the pollution of sewage discharged from residential area was more serious than that of other 4 sampling sites.
