基于WebGIS的雨污合流排水溢流污染去除方法研究

Research on Pollution Removal Method for Rainwater and Sewage Combined Drainage Overflow based on WebGIS

针对常规的溢流污染去除方法不能同时将溢流中的COD和TP污染物质去除的问题,设计基于WebGIS的雨污合流排水溢流污染去除方法。在调蓄池入口和出口附近安装液位传感器,利用WebGIS获得污水溢流数据,并对数据进行预处理,根据数据判断污水水量,将溢流污水送入至旋流分离器,去除溢流中重金属污染物,将剩余水体送入至设计好的沉淀池中,去除水体中的其它杂质,最后利用消毒装置去除水体中的病菌完成溢流污染去除。与常规的两种方法相比,基于WebGIS的溢流污染去除方法能够同时将溢流中的COD和TP污染物质去除干净,适合应用在雨污合流排水溢流污染去除中。

Aiming at the problem that conventional overflow pollution removal methods cannot simultaneously remove COD and TP pollutants in the overflow,this paper designed a method for removing overflow pollution from rain and sewage combined drainage based on WebGIS.By Install liquid level sensors near the entrance and exit of the storage tank,it uses WebGIS to obtain sewage overflow data,and pre-process the data,determine the amount of sewage water based on the data,and send the overflow sewage to the cyclone to remove the overflow.For heavy metal pollutants,the remaining water is sent to the designed sedimentation tank to remove other impurities in the water.Finally,the disinfection device is used to remove the bacteria in the water to complete the overflow pollution removal.Compared with the conventional two methods,the overflow pollution removal method based on WebGIS can remove the COD and TP pollutants in the overflow at the same time,which is suitable for the removal of rainwater and sewage drainage overflow pollution.
