DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figures 1 to 4As shown, an adjustable water treatment aeration tank includes an aeration tank 1, a controller 2, an aeration pipe 9 and a float type water level gauge 11. An aeration pump 7 is arranged below the left side of the aeration tank 1. The aeration tank 1 increases the oxygen content in the water body by exposing the water body to the air, promotes the degradation of organic matter and the removal of pollutants in the water body, thereby improving the water quality. The bottom end surface of the aeration pump 7 is connected to an air inlet pipe 8. The aeration pump 7 and the air inlet pipe 8 can transport bubbles to the aeration pipe 9, increase the oxygen content in the water body, promote the degradation of organic matter and the removal of pollutants in the water body, thereby improving the water quality. The aeration pipe 9 is arranged at the bottom end surface of the inner cavity of the aeration tank 1, and the two ends of the air inlet pipe 8 are respectively connected to the aeration pump 7. It is connected to the aeration pipe 9. An aeration plate 91 is arranged on the top surface of the aeration pipe 9. Several groups of aeration plates 91 are arranged, and the several groups of aeration plates 91 are arranged at equal intervals on the top surface of the aeration pipe 9. The top surfaces of the several groups of aeration plates 91 are circular structures with several small holes. The aeration pipe 9 transmits the gas delivered by the air inlet pipe 8 to the inside of the aeration plate 91, and the gas delivered by the air inlet pipe 8 is discharged by using the circular structure of several small holes on the surface of the aeration plate 91. The several groups of aeration plates 91 are arranged at equal intervals, so that the gas can be sprayed into the water body evenly and in large quantities, thereby increasing the oxygen content in the water body, promoting the degradation of organic matter and the removal of pollutants in the water body, and thus improving the water quality.

[0023] A fixing frame 10 is provided on the left side of the inner cavity of the aeration tank 1. The fixing frame 10 is provided with two groups. The two groups of fixing frames 10 can fix the float type water level gauge 11 to prevent it from loosening due to water flow. The float type water level gauge 11 is provided in the inner cavity of the two groups of fixing frames 10. The two ends of the float type water level gauge 11 are respectively installed at the center of the inner cavity of the two groups of fixing frames 10. The float type water level gauge 11 can measure the water level in the aeration tank 1, provide reliable water level monitoring data, and send a signal to the controller 2. A float 12 is sleeved at the center of the float type water level gauge 11. The outer surface of the float type water level gauge 11 is meshed with the inner surface of the float 12, and the inside of the float 12 is filled with air. The air filled inside the float 12 enables it to float and sink in the water, and is meshed with the outer surface of the float type water level gauge 11. Thus, the outer surface of the float water level gauge 11 can move up and down according to the change of the water level. A water inlet 3 is arranged above the left side of the aeration tank 1, and a first electric valve 4 is arranged at the center of the water inlet 3. The water inlet 3 controls the water inflow through the first electric valve 4, so as to keep the water level and flow in the aeration tank 1 stable. A water outlet 5 is opened at the center of the right side of the aeration tank 1, and a second electric valve 6 is arranged at the center of the water outlet 5. The water outlet 5 controls the water outflow through the second electric valve 6, so as to keep the water level and flow in the aeration tank 1 stable. The controller 2 is arranged above the left side of the aeration tank 1. The controller 2 can receive the signal of the float water level gauge 11 and control the switch of the first electric valve 4 and the second electric valve 6 to realize automatic monitoring and control of the water level.

[0024] A sludge pipe 13 is installed on the left side of the bottom end surface of the aeration tank 1, and a sludge pump 14 is arranged at the center of the sludge pipe 13. The sludge pipe 13 discharges the treated sludge from the equipment through the sludge pump 14, so as to keep the equipment clean and avoid the accumulation of sludge and pollutants, which is beneficial to the normal operation of the equipment and the stability of water quality. A transmission rod 15 is arranged in the inner cavity of the aeration tank 1. The transmission rod 15 protrudes from the right side of the aeration tank 1 and is provided with a motor 17. The transmission rod 15 is driven by the kinetic energy output by the motor 17, and the outer surface of the transmission rod 15 is provided with stirring blades 16. The stirring blades 16 are provided with eight groups. The transmission rod 15 and the stirring blades 16 are stirred by the motor 17, and the water in the pool and the sludge at the bottom are fully mixed, so that the oxygen content in the water is increased, which is beneficial to the growth and metabolism of microorganisms in the water, and promotes the degradation of organic matter and the removal of pollutants.

[0025] In summary, if Figures 1 to 4 As shown, in the adjustable water treatment aeration tank, wastewater enters the aeration tank 1 through the water inlet 3. When the water level needs to be raised, the first electric valve 4 at the water inlet 3 is controlled to be opened through the controller 2. When the water level reaches the required height, the float 12 of the float-type water level gauge 11 floats upward with the change of the water level, and the monitored signal is transmitted to the controller 2. The controller 2 closes the first electric valve 4 of the water inlet 3 to keep the water level at a stable height. When the water level needs to be lowered, the second electric valve 6 controls the water outlet 5 through the controller 2. When the water level reaches the required position, the float 12 of the float-type water level gauge 11 floats upward with the change of the water level. The water level changes downward, and when the water level is lowered to a preset position, a signal is transmitted to the controller 2. The controller 2 controls the second electric valve 6 to close the water outlet 5, and keeps the water level within the required appropriate range, thereby adjusting the height of the water level. When the water level is high, the mixing degree of oxygen solubility with the water body is lower, and the shallower the water depth, the higher the mixing degree of oxygen solubility with the water body. Therefore, by adjusting the water level of the aeration tank 1, the oxygen solubility in the water body is adjusted, so that automatic water level control can be achieved, ensuring that the water level in the equipment is always within the set water level range, thereby affecting the distribution of pollutants and nutrients in the water body;

[0026] Two sets of fixing frames 10 fix the float water level gauge 11, and the aeration pump 7 injects air into the aeration pipe 9 through the air inlet pipe 8. The aeration plate 91 releases the air transported from the aeration pipe 9 evenly into the water of the aeration tank 1. The aeration plate 91 is composed of many small holes, which are arranged at equal intervals to form a flat disc-shaped structure. When the air is released into the water through these small holes, tiny bubbles will be formed. These bubbles will float in the water and slowly rise up with the water flow. The air can be evenly released into the water, and these bubbles will float to the water surface. At the same time, during the floating process, organic matter and pollutants in the wastewater in the water body will be adsorbed onto the surface of the bubbles, thereby bringing them to the water surface, accelerating the degradation of organic matter and the removal of pollutants. During the sewage treatment process, the sludge in the aeration tank 1 will settle to the bottom, and the sludge will be pumped out through the sludge pipe 13 and the sludge pump 14 to maintain the sludge concentration and cleanliness in the aeration tank 1. The transmission rod 15 is driven by the motor 17 to make the eight groups of stirring blades 16 rotate in the water body in the aeration tank 1, thereby increasing the mixing degree of the water body and ensuring that the dissolved oxygen in the water is fully distributed.
