| 摘 要： | 以1996-2006年监测数据为基本依据,采用综合污染指数及spearm an秩相关系数法对苏州市城区河道外城河的水质变化趋势及污染特征进行分析评价。结果表明,河流总体水质呈现好转趋势,外城河水系污染属有机污染类型,主要污染因子为氨氮、石油类、生化需氧量、挥发性酚和高锰酸盐指数,水质严重污染因子已经由石油类转变为NH3-N。对外城河水质转好原因进行分析,由此提出了完善城市基础设施建设、加强河道疏浚、进行引水冲污等污染防治的对策措施。

| Abstract: | According to the monitoring data of 1996 to 2006, the author analyzed their changing trend with integrated pollution index and spearman rank correlation coeflqcient method. The analysis indicated the rivers pollution situation has the change for the better,major pollution factor for NH3 - N, Oil, BOD5 , Volatile Phenol and Permanganate Index. Some countermeasures are brought forward as well. |
