Abstract
Description
Technical Field
[0001] This utility model discloses a metering tank, belonging to the technical field of sewage treatment equipment, specifically relating to a metering discharge device for sewage treatment. Background Technology
[0002] The core function of wastewater treatment is to purify wastewater through physical, chemical, and biological technologies to meet discharge or reuse standards, thereby achieving three core values: environmental protection, resource recycling, and public health protection. Specifically, this manifests in multiple ways, including improving water quality, preventing disease transmission, and promoting the sustainable use of water resources. Wastewater treatment can reduce pollutant emissions: by removing suspended solids, organic matter, and harmful chemicals (such as heavy metals, nitrogen, and phosphorus) from wastewater, it prevents pollutants from entering natural water bodies, avoiding black and odorous water and ecosystem damage. Secondly, it can restore aquatic ecosystems: treated wastewater replenishing rivers and lakes can restore the self-purification capacity of water bodies. Typical cases show that using treated wastewater for wetland restoration can increase biodiversity by more than 30%.
[0003] In existing wastewater treatment technologies, metering tanks are used for flow monitoring. Their design principles and application effects directly affect the operating efficiency and management accuracy of wastewater treatment. However, traditional metering tanks are usually located at the outlet, but when the flow rate at the outlet is too high, the metering tank will overflow, resulting in metering failure. Utility Model Content
[0004] Purpose of the utility model: To provide a metering and discharge device for sewage treatment, and to solve the problems mentioned above.
[0005] Technical solution: A metering and discharge device for wastewater treatment, comprising: a tank, the tank including an inlet area, a metering area, a buffer area and an outlet area;
[0006] The water inlet area has an inlet at its input end and an output end connected to the input end of the metering area. The output end of the metering area is connected to the input end of the water outlet area. The output end of the water outlet area has an outlet. The buffer zone is connected to the metering area.
[0007] The water inlet area is equipped with an energy dissipation retaining wall.
[0008] In a further embodiment, the metering zone is divided into an inlet section, a direct flow section, and an outlet section from left to right;
[0009] The inlet section and the outlet section are trapezoidal in shape. The width of one end of the inlet section is greater than the width of the other end, and the width of one end of the outlet section is less than the width of the other end. The width of one end of the inlet section and one end of the outlet section is the same as the width of both ends of the direct current section.
[0010] The bottom of the DC section slopes downwards from one end to the other, while the bottom of the outlet section slopes upwards from one end to the other.
[0011] In a further embodiment, there are two buffer zones, and the two buffer zones are set independently. The buffer zones are connected to the metering area through through holes.
[0012] In a further embodiment, one buffer zone is connected to the inlet section and the other buffer zone is connected to the DC section.
[0013] In a further embodiment, the top of the water outlet area is provided with an upwardly extending through pipe.
[0014] Beneficial effects: This invention features an energy-dissipating baffle wall inside the inlet area of the metering tank. This baffle wall reduces the pressure when sewage enters, thus preventing metering failure due to excessive inlet flow. Simultaneously, a buffer zone on one side further limits the overall flow rate of the metering tank. Therefore, this invention can accurately measure fluid flow, providing strong support for rational water resource allocation, environmental protection, and industrial process control. Real-time monitoring of flow data helps to adjust water resource usage and allocation strategies in a timely manner, improving work efficiency and resource utilization. Attached Figure Description

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0021] A metering and discharge device for wastewater treatment includes: a tank 1.
[0022] In one embodiment, such as Figures 1 to 2 As shown, the tank 1 includes a water inlet area 2, a metering area 3, a buffer zone 4, and a water outlet area 5;
[0023] The water inlet zone 2 has an inlet 6 at its input end and an output end connected to the input end of the metering zone 3. The output end of the metering zone 3 is connected to the input end of the water outlet zone 5. The output end of the water outlet zone 5 has an outlet 7. The buffer zone 4 is connected to the metering zone 3.
[0024] The water inlet area 2 is equipped with an energy dissipation barrier 8.
[0025] In one embodiment, such as Figures 1 to 2 As shown, the metering zone 3 is divided into an inlet section 9, a direct flow section 10, and an outlet section 11 from left to right;
[0026] The inlet section 9 and the outlet section 11 are trapezoidal in shape. The width of one end of the inlet section 9 is greater than the width of the other end, and the width of one end of the outlet section 11 is less than the width of the other end. The width of one end of the inlet section 9 and the width of one end of the outlet section 11 are the same as the width of both ends of the direct flow section 10.
[0027] The bottom of the DC section 10 slopes downward from one end to the other, and the bottom of the outlet section 11 slopes upward from one end to the other.
[0028] In one embodiment, such as Figures 1 to 2 As shown, there are two buffer zones 4, and the two buffer zones 4 are set independently. The buffer zones 4 are connected to the metering area 3 through the through hole 12.
[0029] In one embodiment, such as Figures 1 to 2 As shown, one buffer zone 4 is connected to the inlet section 9, and the other buffer zone 4 is connected to the direct current section 10.
[0030] In one embodiment, such as Figures 1 to 2 As shown, the top of the water outlet area 5 is provided with an upwardly extending through pipe 13.
[0031] Working principle: When this utility model is in operation, sewage enters the tank 1 through the inlet 6, first enters the inlet zone 2, then passes through the energy dissipation baffle 8 to eliminate pressure, and then enters the metering zone 3. The metering zone 3 uses the throat contraction to form a water level difference for metering. At the same time, it is connected to the buffer zone 4 through the through hole 12. When the flow rate is too large, the sewage is put into the buffer zone 4. Finally, the sewage flows out through the outlet 7 of the outlet zone 5.
[0032] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
