Technical Field

[0001] This utility model relates to the technical field of wastewater treatment and filtration equipment for thermal power plants, specifically a wastewater filtration mechanism for thermal power plants. Background Technology

[0002] Wastewater filtration equipment in thermal power plants is a key facility for achieving standard discharge and recycling of wastewater. Its core function is to remove suspended solids, particulate matter and specific pollutants from wastewater through physical, chemical or combined processes. It typically uses multi-layer filter media such as quartz sand and anthracite to remove suspended particles through interception and adsorption.

[0003] According to Chinese Patent Publication No. CN119409245A, a wastewater filtration mechanism for thermal power plants is provided, including a filter box, a filter screen, the filter screen being used to filter wastewater from thermal power plants; a dynamic mixing component, which moves and rotates with a dosing component, and is used to stir the liquid inside the filter box; and a cleaning mixing component, connected to the dynamic mixing component, which operates along with the dynamic mixing component, and is used to further stir the liquid inside the filter screen and simultaneously clean the filter screen. The filter screen can be used to filter wastewater from thermal power plants. The dynamic mixing component and the cleaning mixing component can rotate with the dosing component, thereby stirring the liquid inside the filter screen, ensuring that the treatment agent can fully contact the wastewater, improving the treatment effect of the treatment agent on the wastewater. The movement of the cleaning mixing component can clean the filter screen, preventing it from becoming clogged and affecting its use.

[0004] However, the current wastewater filtration system for thermal power plants has the following problems: it is not convenient to carry out continuous multi-channel treatment. Traditional wastewater filtration systems for thermal power plants often adopt a single-channel design, which results in overly concentrated treatment and needs to be improved. Utility Model Content
