Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an automatic cleaning device for a secondary sedimentation tank. Background Technique

[0002] The secondary sedimentation tank is an important part of the sewage treatment system, mainly used to complete the solid-liquid separation in the activated sludge process. During sewage treatment, the mixed liquid after biological treatment enters the secondary sedimentation tank. Here, the activated sludge will settle to the bottom of the tank, while the supernatant will be collected and further treated or discharged. In this way, the secondary sedimentation tank not only helps to clarify the treated water, but also can recover the activated sludge. Part of it is refluxed to the aeration tank to maintain the amount of microorganisms required for biological treatment, and the remaining sludge is sent for sludge treatment.

[0003] When the secondary sedimentation tank is working, some sludge, microbial algae, etc. will adhere to the secondary sedimentation tank. The sludge at the bottom of the secondary sedimentation tank can be scraped off by a sludge scraper, while the sludge, algae, microorganisms, etc. on its side walls need to be manually cleaned. The occupied area of the secondary sedimentation tank is relatively large. If manual cleaning is used, it will waste a lot of manpower and material resources. If machine cleaning is used, it may lead to insufficient fitting and cleaning dead corners. For this reason, we propose an automatic cleaning device for a secondary sedimentation tank.
