Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a sedimentation tank for photovoltaic wastewater treatment. Background Art

[0002] Photovoltaic wastewater refers to the wastewater generated in the process of solar photovoltaic power generation. Photovoltaic power generation systems usually use water to cool solar panels to prevent overheating from affecting battery efficiency. These cooling waters will take away some heat and become photovoltaic wastewater.

[0003] A sedimentation tank is a type of equipment used to treat wastewater, mainly used to remove suspended solid particles and partially dissolved pollutants in wastewater. It is usually used in the primary or secondary treatment stage of a water treatment system, and is designed to separate pollutants from water by gravity sedimentation. In the sedimentation tank being transferred, the flow of wastewater in the sedimentation tank may be uneven, causing some pollutants to fail to precipitate effectively. When the existing stirring mechanism mixes the wastewater, most stirring mechanisms are unable to fully and evenly stir the wastewater and drugs to improve the sedimentation effect, resulting in reduced wastewater treatment efficiency and the inability to fully precipitate and remove pollutants in the wastewater. In addition, the inclined tube is a type of equipment for wastewater treatment and other liquid-solid separation, which allows liquid to flow in from the top, while solid particles slide down the tube wall and settle to the bottom of the tube. The lack of a quick-release mechanism may mean that the process of cleaning the inclined tube is more cumbersome, resulting in the inability to completely remove dirt and sediment on the surface of the inclined tube. This may reduce the treatment efficiency of the sedimentation tank and increase the risk of residual pollutants in the wastewater. Utility Model Content
