| 摘 要： | 城市河流治理是改善城市生态环境的重要一环,为了建设健康的城市水环境,有必要对改善河流水环境质量的可行技术方案进行研究。以合肥市十五里河为例,基于MIKE11软件平台构建河流一维水动力水质耦合模型,根据流域污染特征设定三种水质改善方案进行数值模拟分析,评价分析各情景方案的水质改善效果。结果表明:单纯依靠截污不能使国控断面水质达标,同时还会引起断流;考虑截污及污水处理厂尾水提标排放可使国控断面水质显著改善,但由于降雨径流非点源污染影响,部分时段水质不能达标;采取中水回用、就近引巢湖原水补水、截污及初期雨水截留组合措施,不需外调水补水,国控断面水质即可满足规划目标。

| Abstract: | Urban river restoration is an important work for improving urban ecological environment. In order to build a healthy aquatic environ-ment, it is ncessary to study the feasible technical scheme to improve waler quality. One -dimensional hydrodynamic and water quality modelwas constructed based on the MIKE11 software platform. According to the pollution features of Shiwuli basin, three scenarios using dfferentmeasures were planned to analysis and evaluate the efet on water quality improvement. The results indicate that olluant discharges alone bereduced cannot make the water quality of the cross section meet Class v, but it would cause river channel drought out. Instead, the water qualityimprovement in the basin can be achieved by reducing pollutan discharges and enhancing the efluents quality of wastewater treatment plants.However, at some times, water quality cannot meet the standard because of rainfall runoff carrying pollutants into river. The cross section waterquality can meet the standard through cutig off initial ninfal runof, reuaing relimedd water, and upplyring water wih proximity principlewithout an extermal water supply. |
