摘　　要：以陕西省宝鸡市为例,对市区的合流制管道溢流水质特性进行分析.研究认为:随着降雨历时的增加,水体中的SS、CODCr、氨氮和TP的浓度变化范围分别为1352-154.5 mg.L-11、930-210 mg.L-1、57.6-9.4 mg.L-1和8.66-1.7 mg.L-1;这些污染物浓度的变化趋势表现为先迅速增加然后逐渐降低,直至径流结束.结果表明:合流制管道溢流水质指标中的SS和CODCr受地表径流的影响较大,而氨氮和TP受旱季合流制管道水质影响较大.Taking the city of Baoji in Shaanxi Province as an illustration, the characteristics of combined sewer overflows （CSOs） were investigated because it is necessary for the treatment of CSOs and a water management plan for urban stream. CSOs in the city of Baoji were studied between May 2005 to October 2006. The results showed that the changes of concentration of SS, CODCr, NH4^＋-N and TP were 1352-154.5 mg · L^-1 .1930-210 mg · L^-1 ,57.6-9.4 mg · L^-1 and 8. 66-1.7 mg· L^-1 , respectively. The pollutant concentration increased to the peak rapidly and then decreased slowly until the end of overflows during each storm. And the water quality items （SS and CODCr） of CSOs were relative to the runoff in wet-weather, however NH4^＋-N and TP were associated with these of CSOs in dry-weather.
