摘　　要：根据九江市两河治理前后水质的分析情况,综合评价黑臭水体整治后的效果。两河河道治理过程中,通过监测半年的溶解氧、氨氮、高锰酸盐富营养化指标,运用单因子指数法、综合污染指数法计算各种污染物,再结合城市水环境时空特性,分析评价两河流域上、中、下游的水质等级。经过系统化的治理措施及季节气候变化的影响,河道断面监测数据有较大变化,各污染指标均有较大幅度降低,水质状况明显好转。According to the water quality analysis before and after the treatment of two rivers in Jiujiang,the effect of black-odor water treatment is comprehensively evaluated. In the process of treatment,by monitoring the eutrophication indexes of dissolved oxygen,ammonia nitrogen and permanganate for half a year,the single factor index method and the comprehensive pollution index method are used to calculate various pollutants,combined with the temporal and spatial characteristics of urban water environment,the water quality grade of the upper,middle,lower stream is analyzed and evaluated. Through systematic treatment measures and the impact of seasonal climate change,the section showes a big change,all the pollution indexes are greatly reduced,water quality is improved.
