Description

Technical Field

[0001] The utility model relates to the technical field of biofilm sewage treatment beds, in particular to a suspended bed biofilm sewage treatment device. Background Art

[0002] The suspended bed is a type of biofilm bed and is mainly used in the field of sewage treatment. The suspended bed is located inside the processor and is suspended in the sewage. Fillers are needed as biofilm carriers to greatly increase the biomass and biological species in the reactor.

[0003] After searching, it was found that the publication number is CN218709584U, and the name is a sewage treatment bed with a biofilm suspended carrier filler. The application proposed the existing Chinese patent publication number CN210133930U, which discloses a mobile bed biofilm suspended carrier filler for sewage treatment. During use, it needs to rely on the aeration device inside the pool to achieve full contact and mixing with water. The biofilm suspended carrier filler is relatively light, so during aeration, the biofilm suspended carrier filler will be diffused to the edge of the aeration by external force, and it is impossible to achieve aeration and full mixing and contact with water in the middle part of the filler. Therefore, the aeration effect of the contact sewage is poor, affecting the sewage treatment effect. By setting an aeration component, starting the fan to make the suction pipe suck external water into the aeration injection pipe, and enter the diversion pipe along the aeration injection pipe, and the air is dispersed through the branch pipe Dispersed into multiple aeration heads, the lower end of the plastic filler can be aerated in the middle part of the plastic filler, and the aerated water flow can fully mix and contact with the inside of the plastic filler, so that the sewage and the biofilm can be fully contacted. After sufficient aeration and oxygenation, the sewage treatment effect is better. However, in actual use, the fan in this application is located on the upper part of the plastic filler, and the fan has a large mass, which causes the overall center of gravity of the plastic filler to move upward, which can easily lead to the problem of unstable center of gravity and overturning in water, seriously affecting the safety of the fan. At the same time, the airflow out of the aeration head generates a vertical upward reaction force, which can easily cause the plastic filler to float up and down with the fluctuation of the airflow velocity, and also cause unstable suspension. At the same time, the aeration head is located below the plastic filler, and is far away from the main working surface of the plastic filler, which limits the working efficiency and can be further improved.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
