INFILTRATION AND INFLOW INVESTIGATION

我们的排查方式

污水管道存在大量外来水进入的状况，地下水、雨水或河水会通过各种途径进入到市政污水管道，致使污水处理厂进水量增多，污水浓度异常增加污水处理系统负荷。综合使用管网信息测绘、人工摸排、仪器探查、水质水量检测等手段，查明外来水来源，随后采取相应的工程或管理措施，减少外来水对污水管道的影响。

Because the infiltration and inflow of non-domestic wastewatersuch as groundwater, rainwater and river water, the volume ofwater in the municipal sewage pipe and wastewater treatmentequipments will increase. We can find out infiltration and inflowby a series methods,including drainage GlS, observation bypersonnel,instrumental detection, flow measurement, qualitytest of water, then reduce its effect by using engineering ormanagement measures.
