Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, in particular to a high-efficiency and energy-saving integrated sewage treatment equipment. Background Art

[0002] Sewage treatment equipment is a kind of equipment that treats domestic sewage and industrial wastewater through filtration, disinfection and other methods to prevent sewage and pollutants from flowing directly into water areas. It is of great significance to improving the ecological environment and protecting water resources. However, compared with cities, there are differences in economic and technical conditions in rural areas. The more mature urban sewage treatment process cannot be used in rural sewage treatment, so it is necessary to design a high-efficiency and energy-saving sewage treatment equipment.

[0003] Before sewage enters the equipment, large debris in the sewage needs to be filtered. Most existing sewage treatment equipment filters sewage by fixing a mechanical screen at the water inlet. However, when using the mechanical screen to filter larger impurities, impurities often get stuck in the gear connection of the mechanical screen, causing the mechanical screen to malfunction and resulting in reduced work efficiency. In addition, most filtration equipment discharges sewage into an aerobic tank to degrade organic matter in the water. The sewage after the degradation reaction is then discharged after a simple filtration treatment. However, the simple filtration treatment cannot filter out bacteria and residual pollutants in the water, resulting in poor sewage treatment effect.

[0004] Therefore, those skilled in the art provide a high-efficiency and energy-saving integrated sewage treatment device to solve the problems raised in the above background technology. Utility Model Content

A connecting pipe 8 is provided, a filtering system 7 is fixedly provided on the other side of the connecting pipe 8, a water outlet pipe 12 is fixedly provided on the side of the box body 1 away from the connecting pipe 8, a solar panel 9 is fixedly provided on the upper end of the box body 1 near the connecting pipe 8, a blower 10 is fixedly provided on the upper end of the box body 1 near the center, a water pump 11 is fixedly provided on the upper end of the box body 1 near the blower 10, a water inlet pipe 14 is fixedly provided on the water inlet of the water pump 11, the other end of the water inlet pipe 14 passes through the box body 1 to the membrane biological reaction system 4, a water outlet of the water pump 11 is fixedly provided with a water pipe 13, the other end of the water pipe 13 passes through the box body 1 to the purification system 6, the purification system 6 includes a dosing tank 601, and a dosing barrel 602 is fixedly provided at the center of the bottom surface of the dosing tank 601;

[0029] Specifically, by integrating the water storage system 2, anaerobic system 3, membrane biological reaction system 4, sludge pool 5, and purification system 6 into the box body 1, not only the footprint of the equipment is reduced, but also the working efficiency of the equipment is improved, while also reducing energy consumption. By designing the filtration system 7, debris in the sewage is filtered to prevent debris from entering the equipment and causing blockage, affecting the normal operation of the equipment. By designing the solar panel 9, solar energy is converted into electrical energy to power the equipment, reducing the power supply pressure of the equipment and saving energy consumption. By setting the blower 10, oxygen is provided to the aerobic microorganisms in the aerobic pool 401, so that they can degrade organic matter in the water. The function of the water pump 11 is to concentrate the filtered water into the purification system 6. By setting the dosing tank 602, disinfectant can be provided to further improve the water quality of the effluent.

The other end of the water supply pipe 203 passes through the first partition 15 and leads to the anaerobic system 3;

[0031] Specifically, by setting up a water storage system 2, the fluctuation of the water inlet flow can be balanced, avoiding the impact of excessive or insufficient water volume on the treatment system in a short period of time, and ensuring stable operation of the system. By setting up a submersible pump 202, the liquid in the water storage tank 201 can be sent to the anaerobic system 3 through the water supply pipe 203.

[0032] Reference Figure 2 The anaerobic system 3 includes an anaerobic tank 301, a stirrer 302 is fixedly provided at the center of the bottom surface of the anaerobic tank 301, and a one-way valve 304 is fixedly provided on the upper part of the second partition 16;

[0033] Specifically, by setting up an anaerobic system 3, anaerobic microorganisms are used to degrade organic matter in sewage, especially effectively removing high concentrations of biodegradable organic matter under anoxic conditions. By designing an agitator 302 to stir the liquid, the anaerobic microorganisms are fully in contact with the organic matter in the water, thereby enhancing the degradation effect. By setting up a one-way valve 304, the liquid in the anaerobic tank 301 can flow into the aerobic tank 401, while the liquid and gas in the aerobic tank 401 cannot enter the anaerobic tank 301, thereby preventing the anaerobic tank 301 from entering the air, thereby inhibiting the anaerobic microorganisms from degrading the organic matter.

[0034] Reference Figure 2-5 The membrane biological reactor system 4 includes an aerobic tank 401. A reaction cabinet 403 is fixedly provided at the center of the bottom surface of the aerobic tank 401. An MBR diaphragm 408 is fixedly provided inside the reaction cabinet 403. An output pipe 409 is fixedly provided at the upper end of the reaction cabinet 403. The output pipe 409 is sleeved inside the water inlet pipe 14. A sludge pump 405 is fixedly provided at the bottom surface of the aerobic tank 401 near the reaction cabinet 403. A sludge delivery pipe 406 is fixedly provided at the output end of the sludge pump 405. The other end of the sludge delivery pipe 406 passes through the third partition 17 and leads to the sludge tank 5.

[0035] Specifically, by setting up an aerobic tank 401, the organic matter in the sewage can be further degraded. The MBR diaphragm 408 fixed inside the reaction cabinet 403 can finely filter the sewage and filter out residual pollutants and bacteria in the water. By setting up an output pipe 409 above the reaction cabinet 403 and fitting it with the water inlet pipe 14, the filtered water can be pumped out through the water pump 11. By setting up a sludge pump 405, the sludge can be sent to the sludge tank 5 through the sludge pipe 406.

[0036] Reference Figure 2-3 The air outlet of the blower 10 is fixedly sleeved with an air supply pipe 407, and the other end of the air supply pipe 407 is fixedly sleeved with a diversion pipe 402. The upper end of the diversion pipe 402 is fixedly provided with an air outlet nozzle 404, and the air outlet nozzle 404 is located directly below the reaction cabinet 403;

[0037] Specifically, the blower 10 is provided to deliver air into the aerobic tank 401 through the air supply pipe 407. The diversion pipe 402 and the air outlet nozzle 404 are provided to increase the contact probability between air and aerobic microorganisms, thereby enhancing the degradation ability of aerobic microorganisms. At the same time, the ejected gas stirs the liquid, so that the aerobic microorganisms are in full contact with the organic matter in the water, thereby enhancing the degradation effect. The air outlet nozzle 404 is provided directly below the reaction cabinet 403, so that the reaction cabinet 403 limits the diffusion of the gas ejected from the air outlet nozzle 404, thereby increasing the degradation rate.

[0038] Reference Figure 6-7 The filtering system 7 includes a water channel 705, a storage box 701 is fixedly provided on one side of the water channel 705, a motor 702 is accommodated inside the storage box 701, a drum screen 703 is rotatably provided between the inner walls on both sides of the water channel 705, and the bearing of the drum screen 703 passes through the water channel 705 and is fixedly sleeved on the output end of the motor 702. A collecting trough 704 is fixedly provided between the inner wall of the water channel 705 on the side close to the connecting pipe 8 and the drum screen 703, and one side of the collecting trough 704 is tightly fitted with the drum screen 703;

[0039] Specifically, by setting up a motor 702 to drive the drum screen 703 to rotate counterclockwise, the rotating drum screen 703 can effectively intercept debris in the sewage while avoiding clogging of the canal 705. By designing one side of the collection tank 704 to fit closely with the drum screen 703, the rotating drum screen 703 can scrape the debris attached to the surface into the collection tank 704.

[0040] Working principle: When the device is in use, sewage is first filtered by the filtering system 7 before entering the device. During the filtering process, the motor 702 drives the drum screen 703 to rotate counterclockwise. The rotating drum screen 703 intercepts debris in the sewage while preventing the water channel 705 from being blocked. One side of the collection tank 704 is in close contact with the drum screen 703, so that the rotating drum screen 703 can scrape the debris attached to the surface into the collection tank 704.

[0041] Secondly, the filtered sewage enters the water storage tank 201 through the connecting pipe 8, and is then introduced into the anaerobic tank 301 through the submersible pump 202. In the anaerobic tank 301, the organic matter in the sewage is degraded. Then the sewage enters the aerobic tank 401 through the one-way valve 304. In the aerobic tank 401, the organic matter in the sewage is further degraded. After that, the sewage is filtered through the MBR membrane and is pumped into the purification tank by the pumping pump 11. The purified water flows out from the outlet pipe 12, and the sludge precipitated in the aerobic tank 401 is sucked into the sludge tank 5 through the sludge pump 405.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
