[0002] Aeration tank is a key component in the physical and chemical treatment process and is mainly used in the biological treatment stage. In sewage treatment, air or pure oxygen is introduced into sewage to provide the oxygen required by aerobic microorganisms, promote the growth and metabolic activities of aerobic microorganisms, and thus decompose and remove organic pollutants in sewage. Aeration is a key step in biological treatment processes such as activated sludge method, biological filter, oxidation ditch, etc. It is essential for removing pollutants such as organic matter, nitrogen and phosphorus in sewage. During the aeration process, gas is ejected through the upward aeration nozzle. Since the aeration nozzle is at the bottom of the aeration tank, a large amount of sludge and other impurities will be produced and precipitated during the decomposition process of sewage. The sludge can easily enter the air jet during the sedimentation process, causing the aeration nozzle to be blocked by the sludge, affecting the aeration effect. Utility Model Content

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with traditional aeration nozzles, during the sewage aeration process, gas is ejected through the upward nozzles. Since the aeration nozzles are at the bottom of the aeration tank, a large amount of impurities such as sludge will be generated and precipitated during the decomposition of sewage. The sludge can easily enter the air outlet during the precipitation process, causing the aeration nozzle to be blocked by the sludge, affecting the aeration effect. By setting up an aeration structure and a rotating structure in conjunction with each other, the aeration nozzles can be shielded and protected, and the sludge can be filtered and intercepted, which can avoid direct contact between the nozzles and the sludge. By setting up lateral aeration nozzles, the probability of sludge settling into the nozzles can be reduced, preventing the sludge from clogging the aeration nozzles and affecting the aeration efficiency.

[0014] 2. Use the aeration pipe to divert the air and then spray it out through the nozzle. The nozzle set on the side reduces the probability of sludge precipitation blocking the nozzle. The air outlet set at the bottom of the air hood prevents sludge from blocking the air outlet while dispersing the other air into fine bubbles, increasing the efficiency of gas and sewage mixing. The rotating driven gear drives the protective frame to rotate through the connecting shaft, thereby driving the outer rotating plate to rotate, stirring the sewage in the aeration tank body, accelerating the flow of sewage, and making the gas blown out of the nozzle and sewage mix more evenly. The sludge generated by the sludge reaction is intercepted by the filter and the protective frame to avoid interference with the internal nozzle.

[0015] 3. The sewage is discharged into the aeration tank body through the water inlet pipe for aeration treatment. After the reaction is completed, the outlet pipe is opened by using a valve, and the aerated sewage is discharged from the aeration tank body through the outlet pipe. The air is blown into the main air pipe by using an air supply pump. The air can be transported through the air supply pipe. The stirring motor is used to drive the stirring shaft to rotate. By driving the stirring rod to rotate, the sewage in the aeration tank body is stirred, so that oxygen and sewage are evenly mixed, thereby increasing the aeration efficiency. The driving motor is used to drive the driving shaft to rotate, thereby driving the driven gear to rotate through the driving gear, thereby transmitting power. BRIEF DESCRIPTION OF THE DRAWINGS
