无配套市政管网的地铁车站污水排放溢流污染负荷控制方法研究

Subway Station Sewage Discharge Overflow Pollution Load Control Method without Supporting Municipal Pipe Network

为了更加有效的控制地铁车站污水排放溢流污染负荷,提出无配套市政管网的地铁车站污水排放溢流污染负荷控制方法。通过水利、水质模型软件AgSWMM,结合物联网在线监测技术以及地理信息等技术,组建无配套市政管网的地铁车站污水排放流域的水动力模型,分别设计不同的降雨时间进行场景模型,详细分析对比了地铁车站污水排放溢流污染负荷控制方法改进前后的污染物浓度削减度等,实验结果验证了所提无配套市政管网的地铁车站污水排放溢流污染负荷控制方法的综合有效性。

In order to control the sewage discharge overflow pollution load of the subway station more effectively,the control method of sewage discharge overflow pollution load of metro station without supporting municipal pipe network is proposed.Through the water conservancy and water quality model software AgSWMM,combined with the Internet of Things online monitoring technology and geographic information technology,the hydrodynamic model of the subway station sewage discharge basin without supporting municipal pipe network was established,and different rainfall time were designed to carry out the scene model.The reduction of pollutant concentration before and after the improvement of the sewage discharge overflow pollution control method of the metro station,the experimental results verify the comprehensive effectiveness of the proposed method for controlling the sewage discharge overflow pollution of the metro station without the supporting municipal pipe network.
