[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 3, the utility model provides an embodiment: a precise aeration control device for sewage treatment, including an aeration tank 1, a bracket 6 is slidably connected to the top of the aeration tank 1, a storage box 7 is fixedly connected to the upper surface of the bracket 6, an aeration fan 8 is fixedly connected to the inside of the storage box 7, an air pump 9 is fixedly connected to the upper surface of the bracket 6, an exhaust pipe 10 is fixedly connected to the input end of the air pump 9, a delivery pipe 12 is fixedly connected to the output end of the air pump 9, a connecting pipe 11 is connected to the inside of the storage box 7, a sealing plate 16 is fixedly connected to the inside of the connecting pipe 11, an adjusting plate 17 is rotatably connected to the outer wall of the sealing plate 16, an outer wall of the adjusting plate 17 is rotatably connected to the inside of the exhaust pipe 10, a worm gear 18 is fixedly connected to the outer wall of the adjusting plate 17, a worm 19 is rotatably connected to the upper surface of the bracket 6, the worm 19 and the worm gear 18 are meshed, a handle 20 is fixedly connected to the top of the worm 19, and a lifting component is provided on the lower surface of the bracket 6;

[0031] Specifically, by using the worm 19 and the worm wheel 18 to adjust the outlet area on the sealing plate 16, the amount of gas entering the sewage can be controlled very accurately. This control method allows the operator to manually adjust the gas flow rate according to the treatment requirements, providing a flexible operation method to cope with different sewage treatment conditions. By accurately controlling the gas flow rate, unnecessary energy consumption can be reduced. The operation of starting and stopping the aeration fan 8 and the air pump 9 can be carried out according to actual needs, avoiding excessive aeration and energy waste.

[0032] Reference Figure 1-Figure 3 The lifting assembly includes a cylinder 5, a driving end of the cylinder 5 is fixedly connected to the lower surface of the bracket 6, a fixing plate 4 is fixedly connected to the lower surface of the cylinder 5, an outer wall of the fixing plate 4 is fixedly connected to the outer wall of the aeration tank 1, a shunt pipe 13 is fixedly connected to the bottom end of the delivery pipe 12, a plurality of aeration pipes 14 are fixedly connected inside the shunt pipe 13, and a nozzle 15 is fixedly connected to the outer wall of the aeration pipe 14;

[0033] Specifically, by adjusting the depth of the aeration tube 14, the distribution of gas can be flexibly adjusted according to the depth of the sewage and the oxidation demand. This is especially useful for pools of different depths or in cases where the water level changes greatly, ensuring that oxygen can be evenly distributed throughout the water body. Adjusting the position of the aeration tube 14 can affect the rising time of the bubbles in the water, thereby affecting the dissolution rate of oxygen. Generally speaking, the deeper the aeration tube 14, the longer the bubbles stay in the water and the higher the dissolution rate, which helps to improve aeration efficiency and reduce oxygen waste. Accurately controlling the position of the aeration tube 14 can avoid excessive aeration, thereby reducing unnecessary energy consumption. By optimizing the generation and distribution of bubbles, operating costs can be reduced while maintaining treatment efficiency.

[0034] Reference Figure 1 and Figure 4A motor 21 is fixedly connected to the upper surface of the bracket 6, a rotating rod 22 is fixedly connected to the driving end of the motor 21, an outer wall of the rotating rod 22 is rotatably connected to the inside of the bracket 6, a connecting plate 23 is fixedly connected to the outer wall of the rotating rod 22, a plurality of stirring blades 24 are fixedly connected to the outer wall of the connecting plate 23, a brush 25 is fixedly connected to the bottom end of the rotating rod 22, a filter screen 26 is fixedly connected to the inside of the aeration tank 1, an upper surface of the filter screen 26 and a lower surface of the brush 25 are fitted together, a water inlet pipe 2 is penetrated and connected to the upper end of the outer wall of the aeration tank 1, a valve 3 is arranged inside the water inlet pipe 2, a water pump 27 is fixedly connected to the lower end of the outer wall of the aeration tank 1, an input end of the water pump 27 is fixedly connected to a pumping pipe 28, an outer wall of the pumping pipe 28 is fixedly connected to the inside of the aeration tank 1, and an output end of the water pump 27 is fixedly connected to a drain pipe 29;

[0035] Specifically, by starting the stirring blades 24, the sewage is fully stirred in the aeration tank 1. This can break the static state of the water body and increase the contact area between the bubbles and the water, thereby improving the dissolution rate and utilization rate of oxygen. The movement of the stirring blades 24 helps to evenly distribute the oxygen in the entire aeration tank 1, which is very important for the activity of microorganisms in the biological treatment process because they need a uniform oxygen supply to maintain their metabolic activities. Through stirring, the suspended particles and soluble pollutants in the sewage react more fully with oxygen, which increases the biodegradation rate of organic matter, thereby improving the overall sewage treatment efficiency. The stirring process can prevent heavy substances from depositing at the bottom of the tank, maintain the fluidity of the sewage system, reduce the frequency and difficulty of cleaning the bottom of the tank, and also avoid the formation of anaerobic conditions.

[0036] Working principle: When the device needs to be used, first open the valve 3 connected to the water inlet pipe 2, and introduce the sewage into the aeration tank 1 through the water inlet pipe 2, then start the aeration fan 8 inside the storage box 7 to introduce air into the storage box 7, then start the air pump 9 to extract the air inside the storage box 7 through the exhaust pipe 10 and the connecting pipe 11, then introduce the air into the diversion pipe 13 through the delivery pipe 12, and finally discharge it through the nozzle 15 connected to the air guide pipe to aerate the sewage. When it is necessary to manually adjust the gas reserve, turn the handle 20 to rotate the worm 19, and then the rotation of the worm 19 drives the worm wheel 18 to rotate, and the worm wheel 18 drives the adjustment plate 17 to rotate in a close manner. The outer wall of the sealing plate 16 rotates, and the effective area of ​​the air outlet of the sealing plate 16 is adjusted with the adjusting plate 17 to realize the function of controlling aeration. The cylinder 5 connected to the starting fixed plate 4 moves the bracket 6 upward to adjust the height of the aeration pipe 14 inside the sewage to achieve a more precise aeration effect. Then, when the aeration effect needs to be improved, the motor 21 is started to rotate the rotating rod 22. The rotation of the rotating rod 22 rotates the fixed plate and the stirring blade 24. The sewage is fully stirred by the rotation of the stirring blade 24, and finally filtered through the filter screen 26. The water pump 27 is started to pump out the treated sewage through the suction pipe 28 and discharge it through the drain pipe 29.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
