The filter tank 2 and the clamping plate 4 are movably connected to the stirring shaft 5.

[0025] During use, when wastewater enters the reaction tank 1 through the water inlet pipe 10, the wastewater will be filtered through the filter tank 2. In order to prevent the filter eye from being blocked by impurities inside the wastewater, the staff starts the linear motor 9. The output shaft of the linear motor 9 drives the stirring shaft 5 to rotate. The rotation of the stirring shaft 5 drives the first stirring blade 3 and the clamping plate 4 inside the filter tank 2, so that the wastewater drives the internal impurities to rotate in the filter tank 2, thereby accelerating the filtering flow of the wastewater. At the same time, the clamping plate 4 drives the filter tank brush 401 to clean the filter eye of the filter tank 2 to prevent the filter eye from being blocked by impurities and affecting the flow of sewage. A wall brush is provided on the side of the clamping plate 4 close to the filter tank 2 and the wall of the reaction tank 1, which is convenient for flushing and cleaning the filter tank 2 and the inner wall of the reaction tank 1.

There is a gap between the filter tank 2 and the inner wall of the reaction tank 1, which is convenient for the flow filtration of the wastewater. It is also beneficial to the fusion of the reactant and the filtered wastewater, and prevents the impurities inside the filter tank 2 from affecting the fusion of the reactant and the wastewater.

[0036] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: when wastewater enters the reaction tank 1 through the water inlet pipe 10, the wastewater will be filtered through the filter tank 2. In order to prevent the filter eye from being blocked by impurities inside the wastewater, the staff starts the linear motor 9. The output shaft of the linear motor 9 drives the stirring shaft 5 to rotate. The rotation of the stirring shaft 5 drives the first stirring blade 3 and the clamping plate 4 inside the filter tank 2, so that the wastewater drives the internal impurities to rotate in the filter tank 2, thereby accelerating the filtering flow of the wastewater. At the same time, the clamping plate 4 drives the filter tank brush 401 to clean the filter eye of the filter tank 2 to prevent the filter eye from being blocked by impurities.
