The pump station rainwater treatment system is further provided with a second control valve 220 and a third control valve 230 which are respectively arranged at the front ends of the water inlet pipes of the water collecting tank 120 and the regulating reservoir 110 and are used for respectively controlling the rainwater input of the water collecting tank 120 and the regulating reservoir 110. The pump station rainwater treatment system is also provided with a fourth control valve 240, which is arranged on a main water inlet pipeline of the pump station and used for controlling rainwater or sewage to enter the pump station, and the fourth control valve 240 is opened daily and closed when the pump station is stopped or overhauled. The pump station rainwater treatment system is provided with a grid 310, and the grid 310 is arranged behind the fourth control valve 240 along the water pipe and is used for intercepting larger impurities in the inflow water. The pump station rainwater treatment system is also provided with a fifth control valve 250 which is arranged on the total water outlet pipeline of the pump station and used for controlling the treated rainwater reaching the standard to be discharged into the water environment. The pump station rainwater treatment system is also provided with a water quality instrument 320 and a water pump 330, wherein the water quality instrument 320 is arranged on an output pipeline of the oil-water separation assembly 150 and used for detecting treated rainwater, and the water pump 330 is arranged in the water collecting tank 120 and the regulating tank 110 and used for discharging the rainwater. The pump station rainwater treatment system is also provided with a sixth control valve 260 arranged on the pipeline for the rainwater which is not up to standard after the second step treatment to flow to the water collecting tank 120, so as to control the rainwater to return to the water collecting tank 120. The regulating reservoir 110 and the water collecting reservoir 120 are also provided with a level sensor 340 for transmitting a level signal.

The fourth control valve 240 is opened daily, and rainwater during rainfall and sewage generated in daily life enter the pump station through the fourth control valve 240. When rainfall does not start, the second control valve 220 is kept in an open state, the first control valve 210 and the third control valve 230 are closed, and sewage generated in daily life enters the sump 120 through the second control valve 220. When rainfall starts, after the controller 160 monitors the strong rain signal sent by the rain gauge 130, the rain and sewage passes through the fourth control valve 240 and then reaches the grid 310 to perform preliminary filtration, and the impurities with larger volume are separated from the rain and sewage to reduce the load of subsequent rain and sewage treatment facilities, so that the subsequent water pipe 40 and the water pump 330 are prevented from being blocked. After the strong rain signal received by the controller 160 reaches the preset threshold value through calculation, the rainfall at this time is larger, and a larger load is easily caused on the sewage pipe network and the sewage plant, and the controller 160 closes the second control valve 220 and opens the third control valve 230 to allow the rain and sewage to flow into the regulation reservoir 110. After the rainfall is over, the controller 160 controls the water pump 330 in the regulating reservoir 110 to transmit the rain and sewage to the pipeline, wherein whether the rainfall is stopped can be judged by calculating whether the rain intensity is zero in unit time by the controller 160, or a rainfall stopping instruction can be issued manually. The output pipeline of the regulating reservoir 110 conveys the rain and sewage to the sediment separation assembly 140, the sediment separation assembly 140 is preferably a cyclone sand remover, the sediment separation assembly 140 is started to drive the rain and sewage to rotate at a high speed, fine solids such as gravel, scale, lime and the like with high density are deposited at the bottom of the device and discharged along with sewage, the liquid with low density rises, and the liquid is discharged from a water outlet and enters the pipeline to complete the first step of treatment of diversion of the rain and sewage. The subsequent rain and sewage enter the oil-water separation assembly 150 through a pipeline, the oil-water separation assembly 150 can select an oil-water separator, the rainwater passes through an oil-water interface of the separator, grease floats to an upper layer, water is precipitated to a lower layer, and the separated water flows out of the pipeline to complete the second-step treatment of the diversion of the rain and sewage. The water quality meter 320 provided in the system detects the rainwater subjected to the above two-step treatment, detects the COD and turbidity degree of the rainwater, and the water quality meter 320 transmits the detected water quality signal to the controller 160. If the rainwater meets the index requirement, the controller 160 opens the fifth control valve 250 to discharge qualified rainwater into the river; if the rainwater does not meet the index requirement, the controller 160 opens the sixth control valve 260, the unqualified rainwater is collected into the water collecting tank 120, and the water pump 330 arranged in the water collecting tank 120 discharges the sewage into a sewage pipe network. The regulation tank 110 is also provided with a liquid level sensor 340, when rainwater in the regulation tank 110 overflows, the liquid level sensor 340 sends a signal to the controller 160, the controller 160 controls the third control valve 230 to close and open the first control valve 210, the rainwater at the moment has passed the stage of primary rain and sewage, no pollution is caused to the environment without treatment, and the first control valve 210 is opened to directly discharge the rainwater into the water environment.
In the pump station rainwater treatment system of this embodiment, the impurity with larger volume is filtered through the grid 210, the impurity with smaller volume in the rain and sewage is separated through the silt separation assembly 140, finally the grease in the rain and sewage is separated by using the oil-water separation assembly 150, and then whether the water quality meets the index requirement is detected by the water quality instrument 320, and qualified rainwater is discharged into the sewage plant after unqualified rainwater is discharged into the river. Thus, the effect of diversion of rain and sewage is achieved, the impact of the rain and sewage to a sewage pipe network is reduced, the load of a sewage plant facing a large amount of rain and sewage is also reduced, and the waste of sewage treatment medicaments is reduced.
