Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an aeration device for wastewater treatment. Background Technology

[0002] Wastewater aeration is a core process in wastewater treatment. It increases dissolved oxygen concentration by forcibly transferring air or pure oxygen into the wastewater, supporting the metabolic activities of aerobic microorganisms. Its principle is based on the two-membrane theory, increasing the gas-liquid contact area through bubble rupture or mechanical agitation, thus accelerating oxygen dissolution. Aeration not only provides the necessary oxygen for microorganisms to decompose organic matter but also evenly distributes pollutants and microorganisms through mixing, improving reaction efficiency. Furthermore, aeration inhibits anaerobic environments, reduces the formation of harmful gases such as hydrogen sulfide, and promotes the coagulation of suspended solids into flocs, facilitating subsequent sedimentation or filtration.

[0003] Existing aeration devices fail to filter wastewater upon entry, leading to blockages in the bottom and pipes by fine particles. Furthermore, while agitation increases the contact area between wastewater and air during aeration, this method results in a low contact surface, preventing bottom wastewater from reaching the outside air and causing inefficient aeration. To overcome these drawbacks, this invention provides an aeration device for wastewater treatment. Utility Model Content
