  • 摘要: 为了解苏南某市老城区合流制管网溢流污染特征,在苏南某市D排水系统溢流口采集了2种不同降雨强度的水样,检测水样中COD、SS、TN、TP和NH3-N等污染指标的浓度,并对不同降雨强度的水质变化特征与相关性进行分析。结果表明:较高降雨强度下SS、COD、TN、NH3-N和TP的浓度变化范围分别为37~695 mg/L、119~1 441 mg/L、6.2~26 mg/L、2.3~6.3 mg/L、0.07~1.48 mg/L;较低降雨强度下SS、COD、TN、NH3-N和TP的浓度变化范围分别为22~228 mg/L、180~535 mg/L、7.9~24.7 mg/L、3.2~24.2 mg/L 1.1~1.99 mg/L。由于不同降雨强度下雨污水冲击能量不同,在降雨强度较高的情况下,COD、TN与SS的线性相关系数分别为0.6954与0.6234,具有一定的相关性,而低降雨强度下无明显相关性。较高降雨强度时截留去除SS可以有效消减溢流污水中的COD和TN,对溢流污染的控制具有一定指导意义。
    Abstract: Two kinds of combined sewer overflows (CSOs) from different intensity rainfall were collected from D drainage system in order to understand the pollution characteristics in old urban area in South Jiangsu.Water quality including COD,SS,TN,TP and NH3-N of CSOs was tested.Characteristics of water quality and correlation of different water quality indexes were analyzed.Results show that SS,COD,TN,NH3-N and TP are 37-695 mg/L,119-1 441 mg/L,6.2-26 mg/L,2.3-6.3 mg/L,and 0.07-1.48 mg/L,respectively from high intensity rainfall,and 22-228 mg/L,180-535 mg/L,7.9-24.7mg/L,3.2-24.2 mg/L,and 1.1-1.99 mg/L,respectively from low intensity rainfall.Sewer flushing effects are found to be depended on rainfall intensity.Linear correlation of TN and COD with SS in high intensity rainfall is existing,and the correlation coefficients are 0.6954 and 0.6234,respectively.However,no obvious correlation is found from low intensity rainfall.Removal of SS can effectively reduce COD and TN concentration of CSOs from high intensity rainfall,which may provide practical advice for CSOs pollution control.
