However, in rainy days, the flow exceeds the design capacity of the pipe network system, overflow phenomenon can occur, and pollutants remained and deposited in the pipe system in sunny days are carried up together, directly flow into the surrounding water body without any treatment, and cause pollution to the surrounding water body. Urban non-point source pollution caused by CSO becomes a non-negligible index in the current urban water environment pollution treatment, and pollutants discharged into the water body due to combined overflow pollution seriously threaten the ecological environment of the water body, and have great influence on the restoration of the water body function and the regulation of ecological balance.

In order to effectively solve the problem of combined overflow pollution, rapid purification facilities such as a regulating reservoir and the like are required to be built, and regulation and primary treatment are realized.

Therefore, in view of the above technical problems, it is necessary to provide an overflow sewage regulation device and a method for using the same.

S2. If it continues to rain outside, the water level in the first compartment will gradually increase, and the suspension plate will float up along the column and always float on the top of the liquid.

S3. When the suspension plate moves to the end of the column, the suspension plate stops rising. Some of the liquid in the first compartment pool will enter between the mounting platform and the cover plate through the channel. The cover plate is impacted by the liquid and moves away from the mounting platform. At this time, the telescopic belt is pulled and stretched, the diameter of the leakage hole becomes larger, and the liquid between the mounting platform and the cover plate will be discharged through the leakage hole and the through hole respectively.

At the same time, since the suspension plate floats on the upper side of the first compartment, the suspension plate can also block suspended matter in the liquid.

S5. When the liquid level in the first compartment exceeds the first partition, the liquid enters the second compartment through the first filter screen, and the first filter screen is used to further filter the suspended matter in the liquid.

S6. When the liquid level in the second compartment exceeds the second baffle, the liquid enters the third compartment through the third filter screen. The second and third filters can continue to filter the suspended solids in the liquid. Finally, the liquid in the third compartment enters the sewage treatment plant through the drain pipe.

S7. If the rainfall stops, the liquid in the first, second and third compartments will be discharged through the sewage pipe and introduced into the sewage treatment plant.

S8. When it is necessary to clean the bottom of the first compartment pool, connect the cleaning pipe to the clean water supply end. The clean water is sprayed onto the first compartment pool through the nozzle on the straight pipe. Some of the clean water sprayed by the nozzle will fall directly to the bottom of the first compartment pool, and some clean water will enter between the mounting platform and the cover plate through the through hole.

S9. Some of the clean water inside the installation platform is discharged directly to the bottom of the first compartment tank through the channel, and some of the clean water enters the conical groove and impacts the vibrating ball, which causes the installation column and brush bristles to swing irregularly. The irregularly swinging brush bristles can clean the dirt at the bottom of the first compartment tank. The dirt and sewage at the bottom of the first compartment tank can be discharged through the sewage pipe and introduced into the sewage treatment plant.
