Method for separating rainwater from sewage
The invention provides a method for separating rainwater from sewage. The method comprises the steps that the upper end and the lower end in a sewage pipe section are thoroughly isolated by air bags,and then the sewage is emptied through a drainage pump; during upstream operation of a drainage pipe, the downstream in the sewage pipe is thoroughly isolated by the air bags, and the sewage is emptied by the drainage pump; and a wellhead corresponding to the sewage pipe section is isolated from the atmosphere by the air bags, so that a relatively sealed space is formed in the sewage pipe, then high-pressure air flow is introduced by a high-pressure fan, colored smoke is introduced into an inlet of the high-pressure fan, smoke is discharged from a rainwater pipe, a pipe orifice with the smokeis confirmed to be a vent pipe orifice for discharging sewage and waste water on site, the residual pipe is the rainwater pipe, so that the rainwater pipe mistakenly connected to the sewage pipe is exposed completely, and the confirmed rainwater pipe mistakenly connected to the sewage pipe is immediately arranged for engineering correction. The normal production process of a sewage treatment plantcan be guaranteed, and the drainage pipe of the sewage treatment plant can stably and orderly discharge reasonable and standard water flow.
一种从污水中分离雨水的方法，包括：用气囊将污水管区段内的上端及下端彻底隔离，然后用排水泵将污水排空；在排水管的上游作业时，用气囊将污水管内的下游彻底隔离，用排水泵将污水排空；在污水管段相应的井口处用气囊将井口与大气隔离，使污水管内形成一个相对密封的空间，再用高压风机通入高压气流，高压风机的进口处通入有色烟雾、雨水管就会有烟雾排出，有烟雾排出的管口经过现场确认排除污水、废水的通气管口，剩余的就是雨水管，这样错接到污水管的雨水管就会暴露无遗，经过确认的错接到污水管中的雨水管即刻安排工程进行修正。可以保证污水处理厂正常的生产工艺，可以使污水处理厂排水管稳定有序的排出合理达标的水流。
