[0028] like Figure 1-3 As shown, this utility model provides a circulating sewage treatment tank, including a first inlet tank 1, a first water pump 6, a reaction tank 3 and a circulating tank 4;

[0029] The first water inlet pool 1 is connected to the second water inlet pool 2 via a water flow pipe 5. The water flow pipe 5 is inclined, with the end of the water flow pipe 5 near the first water inlet pool 1 located above the end near the second water inlet pool 2. A turbine 7 is installed inside the water flow pipe 5, and the turbine 7 is connected to an energy storage battery 8. The energy storage battery 8 is connected to a first water pump 6, which is installed inside the second water inlet pool 2. The first water pump 6 is used to pump water from the second water inlet pool 2 into the first water inlet pool 1.

[0030] By adding a second inlet pool 2 to the first inlet pool 1, the problem of insufficient sewage treatment pool size during periods of high sewage discharge is solved. At the same time, it avoids the need to build a new inlet pool, thus avoiding the waste of existing resources. When the sewage in the first inlet pool 1 reaches a certain height, the water flows from the water flow pipe 5 to the second inlet pool 2, using the height difference of the water flow to form a natural flow. The turbine 7 is driven to rotate by the water flow, converting the kinetic energy of the water flow into mechanical energy, and further converting the mechanical energy into electrical energy through the connected energy storage battery 8. The energy storage battery 8 is connected to the first water pump 6 to provide power support for the first water pump 6, realizing the recycling of energy and reducing the energy consumption of the system operation.

[0031] The reaction tank 3 is connected to one side of the first inlet tank 1 through an inlet pipe 9. The end of the inlet pipe 9 connected to the reaction tank 3 is located at the center of the reaction tank 3. The reaction tank 3 is equipped with multiple annular treatment zones 10. The multiple annular treatment zones 10 have different functions and are detachable from each other, which facilitates the adjustment of the treatment process or replacement and maintenance according to actual needs. This solves the problem that rural sewage contains more organic matter and the filtration system is prone to clogging during sewage treatment.

[0032] The circulation tank 4 is located around the reaction tank 3. The circulation tank 4 is used to collect the water treated by the reaction tank 3. The circulation tank 4 is equipped with a second water pump 11, which is used to pump the water in the circulation tank 4 to the inlet pipe 9, so that it can re-enter the reaction tank 3 for circulation treatment, thereby further improving the sewage treatment efficiency. The top of one side of the circulation tank 4 is provided with a drain outlet 12, which is used to discharge the treated water.

[0033] The working principle is as follows:

[0034] Wastewater first enters the first inlet tank 1. When the wastewater volume is large, the water level in the first inlet tank 1 rises, and the water flows naturally into the second inlet tank 2 through the inclined water flow pipe 5. This design solves the problem of insufficient wastewater treatment tank capacity and avoids the waste of resources caused by building new inlet tanks. When the water flows from the first inlet tank 1 to the second inlet tank 2 through the water flow pipe 5, the height difference drives the turbine 7 to rotate, converting the kinetic energy of the water flow into mechanical energy. The mechanical energy is then converted into electrical energy and stored through the energy storage battery 8. The energy storage battery 8 provides power to the first water pump 6, which pumps the water from the second inlet tank 2 back to the first inlet tank 1, forming a water circulation flow, realizing energy recycling, and reducing system operating energy consumption. Wastewater enters the reaction tank 3 from the first inlet tank 1 through the inlet pipe 9. The outlet of the inlet pipe 9 is located at the center of the reaction tank 3, flowing from the inside out. The wastewater is filtered through infiltration. The reaction tank 3 is equipped with multiple annular treatment zones 10, each with a different function. The multi-stage treatment improves the wastewater treatment effect. The annular treatment zones 10 are designed to be detachable, which makes it easy to adjust the treatment process or replace and maintain them according to actual needs. This solves the problems of high organic content and easy clogging of the filtration system in rural wastewater. The treated water flows from the reaction tank 3 into the circulation tank 4. The second water pump 11 in the circulation tank 4 pumps part of the water back into the inlet pipe 9, mixes it with the water in the first inlet tank 1, and then enters the reaction tank 3 again for circulation treatment, further improving the wastewater treatment efficiency. The water that meets the discharge standards is discharged through the drain outlet 12 at the top of one side of the circulation tank 4.

Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
