Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an aeration tank for wastewater treatment that can avoid water overflow. Background Technique

[0002] An aeration tank is a device for biological treatment, mainly used to introduce air into organic wastewater that needs to be oxidized, providing oxygen for microorganisms to carry out respiration, thereby promoting the decomposition and purification of organic matter. This device plays a crucial role in the sewage treatment process.

[0003] During the use of the existing aeration tank, the safety water level of the aeration tank is usually monitored. When the water level exceeds the safe range, the water inlet is automatically stopped to prevent water overflow from the aeration tank and cause environmental pollution. However, during rainy days, the water level will continuously rise, and the existing technology cannot drain the wastewater in time when the water level is out of control, easily leading to water overflow from the aeration tank and causing environmental pollution. Moreover, when aerating the wastewater, there will be a large amount of floating matter on the top of the wastewater, and the floating matter will affect the contact effect between air and wastewater, affecting the aeration efficiency of wastewater.

[0004] Therefore, it is necessary to provide a new aeration tank for wastewater treatment that can avoid water overflow to solve the above technical problems. Content of the Utility Model
