In recent years, with the requirement of environmental protection becoming higher and higher, the requirement of sewage disposal and diversion for rainwater and sewage discharge in the field of domestic engineering becomes stricter and stricter, namely, rainwater and sewage wastewater are respectively discharged into corresponding accepting systems: rainwater is discharged into a municipal rainwater pipe network system or a water body, sewage and wastewater are discharged into the municipal sewage and wastewater pipe network system, and the sewage and wastewater are not allowed to be mixed and discharged. Because the initial rainwater quality is poor, sometimes also require to discharge according to dirty waste water. In the actual engineering, more and more drainage departments have more and more strict requirements on sewage disposal and diversion.

Municipal administration rain sewage pump station is the pump station that comes the existing rainwater of water and have dirty waste water again, including traditional civil engineering pump station and the prefabricated pump station of novel integration, the water that comes of present most pump station all belongs to this type, and the play water of this type of pump station does not make strict branch of trash cleaning measure under the general condition, and most are direct to discharge in unison according to the rainwater, if in directly discharging the relatively poor dirty waste water of quality of water rainwater system, will certainly lead to the fact certain pollution to the environment, this also does not accord with the environmental protection requirement and the trend of country.

In order to realize the respective discharge of rainwater, sewage, or initial rainwater with different water qualities, i.e., a rainwater drainage rainwater system, and a sewage drainage system (referred to as a sewage disposal shunt) with poor water quality, such as sewage or initial rainwater, two relatively independent systems of rainwater and sewage are generally arranged in a water collecting tank of a pump house, and are respectively provided with respective drainage pumps, water level control systems, drainage pipelines, and the like, as shown in fig. 1, the rainwater system adopts three water pumps (with a power of 50 KW), the sewage system adopts two water pumps (with a power of 10 KW), a liquid level automatic control system (or other control systems) is adopted to control the water pumps, and the independent pump starting and stopping water levels of the rainwater pump and the sewage pump are arranged to respectively start and stop drainage pumps of different types and numbers when the water quality and the water quantity are different; when the rainwater pump works, the sewage pump stops, and vice versa, and then different drainage routes are matched, so that the aims of cleaning and shunting are fulfilled. The sewage disposal and distribution mode has the advantages that the number of the required water pumps is large, the area of a pump room is large, and the cost of equipment and civil engineering is high; the waste water and the rainwater respectively need independent control systems, so that a pump station control system is complex.

Detailed Description

The present invention is described in more detail below with reference to specific embodiments to facilitate understanding for those skilled in the art.

FIG. 1 shows a conventional rainwater and sewage pump house cleaning and shunting manner, wherein it can be seen from the figure that a rainwater drainage system is composed of three high-power (single pump 50 KW) rainwater pumps, drainage branch pipes of the three rainwater pumps are communicated with a rainwater relief well through a rainwater drainage path, water levels of starting and stopping the rainwater pumps are set, and the rainwater pumps are started and stopped through a rainwater control system; the sewage (wastewater) discharge system is composed of two sewage pumps with small power (single pump 10 KW), and the drainage branch pipes of the two sewage pumps with small power are communicated with the sewage relief well through a sewage discharge path; similarly, the water levels for starting and stopping the sewage pump are set, and the sewage pump is started and stopped by the sewage control system. The two sets of systems respectively start and stop the drainage pumps of different types and numbers, when the rainwater pump works, the sewage pump stops, and vice versa, and then the sewage pump is matched with different drainage routes, so that the purpose of cleaning sewage and shunting is achieved.

Fig. 2 shows the utility model discloses a branch system of decontaminating. As can be seen from the figure, four drainage pumps are adopted in total (two 50KW high power drainage pumps are called as a # 1 pump and a # 2 pump and are mainly used for draining rainwater, two 10KW low power drainage pumps are called as a # 3 pump and a # 4 pump and are mainly used for draining sewage and wastewater), and drainage branch pipes of the four drainage pumps are all communicated with a main drainage pipeline 5; the rainwater drainage route 6 connected with the rainwater relief well is communicated with the main drainage pipeline 5 through a rainwater hydraulic control valve 7, and similarly, the wastewater drainage route 8 connected with the wastewater relief well is also communicated with the main drainage pipeline 5 through a wastewater hydraulic control valve 9.

The working steps are as follows:

1. when light rain, initial rainwater or sewage and wastewater need to be discharged, the water level of the water collecting tank reaches the starting water level of a sewage and wastewater pump (a 3# pump and a 4# pump), the sewage and wastewater pump and a wastewater hydraulic control valve 9 on a corresponding wastewater discharge route 8 are started, and the sewage and wastewater in the water collecting tank is discharged into a wastewater pressure relief well and enters a municipal sewage and wastewater system for treatment;

2. when heavy rain falls, the water level of the water collecting tank continuously rises until the water level reaches the pump starting water level of the first rainwater pump, the first rainwater pump works, the rainwater hydraulic control valve 7 on the rainwater discharge route 6 is opened, the wastewater hydraulic control valve 9 on the wastewater discharge route 8 is closed, water is discharged to a rainwater pressure relief well, and then the water is discharged into a water body or a municipal rainwater pipe network;

3. the water level of the water collecting tank continuously rises along with the duration of rainfall, and at the moment, the second rainwater pump can be started to quickly drain the water in the water collecting tank to a rainwater pressure relief well; if the pump room is large and the number of the rainwater pumps is large, the rainwater pumps can be gradually started, and all the rainwater pumps can be completely started when necessary so as to accelerate the rainwater drainage speed;

4. and gradually closing the redundant water pumps along with the gradual reduction of the water level of the water collecting tank until the rainfall stops, reducing the water level in the water collecting tank to the pump stopping water level, closing all the water pumps and finishing the drainage.
