摘要
市桥河流域水系主要由市桥水道和沙湾水道及多条河涌组成,根据该流域2002-2007年的水质监测资料,参照《地表水环境质量标准》(GB3838-2002),采用单因子评价法和内梅罗综合污染指数分析法,评价该流域总体水质状况。评价结果表明:①市桥河流域水体的主要污染物是粪大肠菌群、NH3-N、TP、COD、石油类;②该流域中游断面由于接纳了各镇街的大量废水,水质最差;③市桥河流域表现出以有机类(COD、BOD5等)、营养类(NH3-N、TP)污染为主的典型特征,与居民生活污水和企业员工生活污水为主的污染源特征相吻合。
The Shiqiao watershed is composed of Shiqiao Watercourse, Shawan Watercourse and some other rivers. According to Environmental Quality Standards for Surface Water in China （GB3838-2002）, the 2002-2007 monitoring data are used to evaluate and characterize the water quality condition of the Shiqiao River watershed based on the comprehensive index methods such as Nemerow Index and solo-factor assessment. Such results are obtained： （1）the main pollutants of the watershed are fecal coliform, NH3--N, TP, COD and oil genus; （2）the degree of water pollution in the middle cross-section of the watershed is the most serious, because much waste water from the towns inflow to the rivers; （3）the organic compounds pollution and the nourishment pollution are the typical characteristic of the Shiqiao River watershed, which fits right in with the fact that domestic sewage is the main pollution source
