[0002] Wastewater treatment refers to the process of treating sewage generated in production, life or other activities to reduce the content of pollutants and meet the discharge standards or reusable water quality requirements. Common wastewater treatment methods include physical treatment (such as filtration, sedimentation), chemical treatment (such as adding chemical agents for coagulation, precipitation, oxidation, etc.), biological treatment (using microorganisms to degrade organic pollutants), etc. These methods can be used alone or in combination, and the appropriate method can be selected according to the nature of the wastewater and the treatment requirements.

[0003] In the wastewater treatment process, the wastewater treatment sedimentation tank required for wastewater pretreatment is indispensable. In the sedimentation tank, there is often a large amount of silt precipitation. Therefore, in order to ensure the continuous use of the sedimentation tank, it is often necessary to regularly clean the sediment at the bottom. The common method is to pump out all the water and then use manual entry to clean the bottom. The whole process is relatively difficult to operate, and the efficiency of manual cleaning is relatively low. Utility Model Content
