摘    要:针对我国城市内河污染日益严重的问题,以巢湖市老城区环城河为研究对象,拟定调水方案,进行调水试验。依据沿河水文水质情况,布设6个实时水质监测点,并将环城河概化为5个河段。应用测得的水文水质数据对各河段不同时间点的含氮污染物负荷进行估算,初步研究了各河段NH3-N、TN负荷量的变化规律。通过对比上下游各河段含氮污染物负荷去除效果,分析调水效果的影响因素,总结个别河段调水效果不佳的原因,提出4条优化意见。并结合实际情况,选取其中可行性较强的1条对其有效性进行实验验证。

关 键 词:城市内河  调水  含氮污染物  负荷变化规律

Abstract:In view of the increasingly serious pollution of urban inland river,a diversion scheme was developed and the corresponding experiments were conducted by taking Huancheng River in the old city region of Chaohu as the object. According to the hydrology and water quality,six water quality monitoring stations were set up and Huancheng River was divided into five sections. Based on the data of the hydrology and water quality,estimates were made in loads of nitrogen pollutants at different time in the five sections. Then preliminary studies were carried out on the load regularity of NH3-N and TN in each section. By comparing the removal efficiency of nitrogen pollutant loads in sections of upstream and downstream,factors affecting water diversion were analyzed in combination with the actual situation. As for the deficiencies in water diversion,four optimization suggestions about the program were proposed. And the effectiveness of the most viable option in them was verified.
Keywords:urban river  water diversion  nitrogenous pollutant  load variation regularity
