摘 要:基于对太湖流域漕桥河小流域主要污染物来源构成和污染特征的分析,对污染物入河量进行了计算和修正.结果表明:漕桥河的CODCr入河总量为1 639.9 t/a,主要来源于工业污染和城镇生活污染;氨氮入河总量为174.6 t/a,主要来源于农业面源和工业污染;总氮和总磷入河总量分别为491.0和34.7 t/a,主要来源于农业面源和城镇生活污染.同时,针对河网地区水系错综复杂的特性,将客水污染纳入污染源范畴,核定客水量,为有效改善河流水环境质量提供了依据.Based on analysis of the main pollutant source composition and pollution characteristics of the Caoqiao River in the Taihu Lake Basin, the total amount of pollutants into the fiver was calculated and corrected. The results showed that the total amount of chemical oxygen demand entering the Caoqiao River was 1639.9 t/a, mostly from industrial pollution and urban life pollution. The total amount of ammonia nitrogen entering the Caoqiao River was 174.6 t/a, mostly from agricultural non-point source pollution and industrial pollution. The amounts of total nitrogen and total phosphorus entering the Caoqiao River were 491.0 and 34.7 t/a respectively, mostly from agricultural non-point source pollution and urban life pollution. In view of the complex characteristics of the fiver water system in the region, guest water is treated as the pollution source. The total amount of guest water was checked ; this provides a foundation for effectively improving water environmental quality in the small river basin.
