Aeration device for sewage treatment

The utility model belongs to the technical field of sewage treatment, and discloses an aeration device for sewage treatment. The aeration device for sewage treatment comprises an aeration tank, a partition plate is fixedly connected to the middle in the aeration tank, vent holes which are uniformly distributed are formed in the partition plate, a biological filter material is laid on the partition plate, and a water outlet pipe is fixedly communicated with the right wall of the aeration tank and located on the upper side of the biological filter material. According to the aeration device for sewage treatment, the oxygen mixing mechanism is arranged, the high flow speed when sewage enters a pool is reasonably utilized to enhance mixing of sewage and oxygen, compared with a traditional oxygen dissolving mode, the aeration device for sewage treatment has the advantages that sewage and oxygen enter the pool together, the mixing effect is better, and the problems proposed in the background technology are solved. 本
