[0002] Wastewater treatment refers to the process of removing pollutants from wastewater through physical, chemical, and biological technologies to meet discharge standards or restore it to a safe, reusable water resource. A common design for wastewater treatment sludge removal devices is a gravity settling system. It is primarily used to remove sludge generated during wastewater treatment to ensure efficient system operation. This type of sludge removal device plays a crucial role in modern wastewater treatment systems, effectively improving efficiency and economy. However, existing sludge removal devices for wastewater treatment still have certain shortcomings; for example:

This application uses the cleaning mechanism to move the sludge into the collection trough, and then uses the lifting component to move the collection trough out of the collection tank, achieving the effect of cleaning sludge. This facilitates quick and convenient sludge treatment for operators, improving the ease of sludge treatment and contributing to improved wastewater treatment quality. However, while this sludge removal device for wastewater treatment can be used effectively, it cannot agitate wastewater during operation, making it difficult to separate wastewater and sludge. Furthermore, it cannot discharge wastewater and sludge separately during sludge removal, increasing the user's workload and reducing equipment efficiency, often causing problems for users.
