Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an underwater oxygenation generator for sewage treatment. Background Art

[0002] At present, sewage treatment is mostly carried out by aeration, which refers to the process of forcibly transferring oxygen in the air to the liquid, with the purpose of obtaining sufficient dissolved oxygen. In addition, aeration also prevents the suspension in the pool from sinking and strengthens the contact between organic matter and microorganisms and dissolved oxygen in the pool. This ensures that the microorganisms in the pool can oxidize and decompose organic matter in the sewage under the condition of sufficient dissolved oxygen.

[0003] At present, sewage aeration treatment is mostly carried out through an oxygenator, which uses an air pump to force external air to the bottom of the sewage pool, thereby increasing the oxygen content in the pool.

[0004] However, in actual use, the oxygenation generator in the prior art mainly transports oxygen to the bottom of the sewage pool through pipes. When the equipment discharges oxygen, air is discharged from the exhaust port. When the equipment is shut down, suspended matter in the sewage is easy to fall into the exhaust port. When oxygen is discharged again, the exhaust port is easily blocked, which affects the oxygen transfer effect to the sewage pool when it is operated again. In view of this, we propose an underwater oxygenation generator for sewage treatment. Utility Model Content
