Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an anaerobic tank for wastewater treatment. Background Technology

[0002] Anaerobic biological treatment technology is a highly efficient wastewater treatment method in which anaerobic bacteria decompose, metabolize, and digest organic matter in wastewater under anaerobic conditions, significantly reducing the organic matter content of the wastewater and producing biogas. As an important form of biological treatment, anaerobic treatment is seeing a continuous development of new anaerobic treatment processes and structures, gradually overcoming the shortcomings of traditional anaerobic processes and achieving significant progress in both theory and practice.

[0003] When treating wastewater, existing anaerobic ponds often contain stubborn oil residue. This oil residue can impair the treatment efficiency of anaerobic bacteria. Furthermore, anaerobic ponds are typically open-air, where wastewater is left to settle and react with the bacteria. However, because the ponds are open, the high oxygen concentration at this location can easily kill or reduce the activity of the anaerobic bacteria. Utility Model Content

This can improve the activity of anaerobic bacteria and enhance the anaerobic effect. With the setting of oil suction components, the sewage in the anaerobic tank can be left to stand for a period of time, and the oil will be at the top of the sewage.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Reference Figure 1-4An anaerobic tank for wastewater treatment includes a base 1, with an anaerobic tank body 2 fixedly connected to the top of the base 1. An adjusting assembly 3 is installed inside the base 1. The adjusting assembly 3 includes a dual-shaft motor 301 fixedly installed inside the base 1. Threaded rods 302 are fixedly connected to the output shafts on both sides of the dual-shaft motor 301. Threaded sleeves 303 are threadedly connected to the surfaces of the threaded rods 302. A connecting plate 304 is fixedly connected to the top of the threaded sleeves 303. The top of the connecting plate 304 is fixedly connected to a tank cover 4. Tank covers 4 are installed on both sides of the top of the anaerobic tank body 2. An oil-absorbing assembly 5 is fixedly connected to the bottom of the tank cover 4. The oil-absorbing assembly 5 includes a storage tank 501 fixedly installed on the top of the tank cover 4. A telescopic rod 502 is fixedly connected to the bottom of the tank cover 4. A float plate is fixedly connected to the bottom of the telescopic rod 502. 503. Oil suction nozzles 504 are installed at both the front and rear positions of the inner cavity of the float plate 503. The top of the oil suction nozzle 504 is connected to a telescopic pipe 505. The top of the telescopic pipe 505 passes through the tank cover 4 and is connected to an oil delivery pipe 506. The other end of the oil delivery pipe 506 is connected to a pump body 507. The pump body 507 is connected to the storage tank 501. By setting the adjustment component 3, the two tank covers 4 can be driven to close or open, which can facilitate the sealing of the anaerobic tank body 2, reduce the contact of sewage with more oxygen, and achieve the sealing of the anaerobic tank, thereby improving the activity of anaerobic bacteria and improving the anaerobic effect. With the setting of the oil suction component 5, the sewage in the anaerobic tank can be left to stand for a period of time, and the oil will be at the top of the sewage, which can suck away the oil on the surface of the sewage, improving the treatment effect of anaerobic bacteria on sewage.

[0024] Example 2: Reference Figure 2 , Figure 3 and Figure 4 The base 1 has slide rails 6 fixedly connected to both sides of the bottom of the inner cavity. Slider 7 is slidably connected to the surface of slide rail 6. The top of slider 7 is fixedly connected to threaded sleeve 303, which can limit and guide the movement of threaded sleeve 303, increasing the stability when threaded rod 302 drives threaded sleeve 303 to move. The bottom of the inner cavity of the two storage tanks 501 is provided with a guide slope 8, which can guide the oil sludge absorbed into the storage tank 501. The opposite sides of the two storage tanks 501 are connected to a discharge pipe 9. The surface of the discharge pipe 9 is provided with a discharge valve, which can facilitate the rapid discharge of oil sludge. The anaerobic tank body 2 has drive motors 10 fixedly connected to both sides of the surface. The output shaft of drive motor 10 passes through the anaerobic tank body 2 and is fixedly connected to a stirring rod 11, which can make the sewage in the anaerobic tank constantly turn over, improving the purification effect of the anaerobic tank.

[0025] The working principle is as follows: In operation, wastewater is added to the anaerobic tank. Simultaneously, the float 503, in conjunction with the telescopic rod 502, remains afloat on the water surface. After the wastewater has settled for a period, the oil sludge will rise to the top. Then, the dual-shaft motor 301 is activated, driving the two threaded rods 302 to rotate simultaneously. These two threaded rods 302, in turn, drive the two threaded sleeves 303 to rotate. The movement of the two threaded sleeves 303 causes the connecting plate 304 to push the tank cover 4 to move. As the tank cover 4 moves and closes, the pump 507 is simultaneously activated. The oil suction nozzle 504 then sucks the oil sludge from the side of the wastewater towards the center, pumping the absorbed oil into the storage tank 501. This process removes the oil sludge from the water surface, improving the anaerobic bacteria's treatment effect on the wastewater. Furthermore, the closing of the two tank covers 4 seals the anaerobic tank body 2, reducing the wastewater's contact with oxygen and effectively enclosing the anaerobic tank. This enhances the activity of anaerobic bacteria and improves the anaerobic effect.

[0026] In summary, this anaerobic tank for wastewater treatment, by setting the regulating component 3, can drive the two tank covers 4 to close or open, thereby facilitating the sealing of the anaerobic tank body 2. This reduces the amount of oxygen that the wastewater comes into contact with, achieving a closed anaerobic tank, which in turn increases the activity of anaerobic bacteria and improves the anaerobic effect. With the oil suction component 5, the wastewater can be left to stand in the anaerobic tank for a period of time, and the oil will be at the top of the wastewater, which can be sucked away from the surface of the wastewater, improving the treatment effect of anaerobic bacteria on wastewater.
