[0002] Urban water pollution and waterlogging caused by storm runoff are major problems that plague urban drainage system design. For a long time, people have always believed that point source pollution is the main cause of water pollution (such as various industrial wastewater, hospital wastewater, domestic wastewater, etc.), and have not realized the serious impact of non-point source pollution on water pollution (such as water pollution caused by urban rainfall surface runoff). With the improvement of urbanization level, the area of impervious surface is rising, which causes the runoff to increase greatly during rainfall. The runoff erosion can carry a large amount of sediment and pollutants, which are directly discharged into the urban water system without treatment, causing serious pollution to the water body.

[0005] The above components achieve the following effects: rainwater can be introduced into the box through the inlet pipe. The initial collected rainwater enters the inside of the bottom end of the box through the flow guide assembly, which can collect and store the initial rainwater. As the wastewater is gradually collected, the float ball can be driven upward by buoyancy until it comes into contact with the bottom end of the flow guide assembly and is sealed. The relatively clean rainwater is discharged from the drain pipe. After the rain, part of the relatively clean rainwater is temporarily stored in the flow guide assembly. The drain assembly guides the wastewater and sediment in the inside of the bottom end of the box out of the box. The float ball moves downward along the guide rod. The clean rainwater at the top end of the box enters the bottom of the box and washes the sediment deposited at the bottom, improving the drainage effect.
[0006] Preferably, the flow guide assembly includes a flow guide hopper fixed inside the box, and the bottom end of the flow guide hopper is connected with a flow guide pipe matched with the float ball.
[0007] The above components achieve the following effects: the flow guide hopper and flow guide pipe can guide the rainwater, and the float ball can seal the wastewater stored at the bottom end of the box.
[0008] Preferably, a convex ring is fixed on the guide rod, and a spring is arranged on the convex ring and sleeved on the guide rod.
[0009] The effect achieved by the above component is that the spring on the convex ring can support the floating ball.
[0010] Preferably, a side opening is formed in the top cover, and a filter piece adapted to the end side of the drain pipe is slidably inserted into the side opening.
[0011] The effect achieved by the above component is that the filter piece can filter rainwater led out from the drain pipe.
[0012] Preferably, the pollution discharge assembly comprises a pollution discharge pump, a suction pipe extending into the box body is fixed at the feed end of the pollution discharge pump, and a discharge pipe is connected to the discharge end of the pollution discharge pump.
[0013] The effect achieved by the above component is that the pollution discharge pump can cooperate with the suction pipe and the discharge pipe to lead out the temporarily stored sewage at the bottom of the box body.
[0014] Compared with the prior art, the urban initial rainwater diversion treatment and storage device has the following improvements and advantages:
[0015] The rainwater initial sewage can be collected and stored, and with the gradual collection of the sewage, the floating ball can be driven to move upward by the buoyancy until the bottom end of the flow guide assembly is abutted and blocked, relatively clean rainwater is discharged from the drain pipe, after the rainy day ends, part of the relatively clean rainwater is temporarily stored on the flow guide assembly, the pollution discharge assembly leads out the sewage and the silt in the inside of the bottom end of the box body from the box body, the floating ball moves downward along the guide rod, the clean rainwater at the top end of the box body enters the bottom of the box body to flush the silt deposited at the bottom, and the pollution discharge effect is improved.
