A through hole adapted to the communicating pipe 8 is opened at the top of the filtering tank 3, and the communicating pipe 8 is inserted and installed in the through hole, so that the internal structures of the stirring tank 1 and the filtering tank 3 are connected and communicated;

[0024] Preferably, the mounting plate 15 is arranged in a rectangular structure and is disposed at the middle and lower part on the outer side of the stirring tank 1. An installation groove adapted to the size of the stirring tank 1 is formed in the middle of the mounting plate 15. The stirring tank 1 is located inside the mounting plate 15. Four groups of fixing blocks 16 are symmetrically mounted on the top of the mounting plate 15. The fixing blocks 16 are arranged in an L-shaped structure. The bottom of the fixing blocks 16 is fixedly connected to the mounting plate 15 through fixing bolts, and the side surface of the fixing blocks 16 is fixedly connected to the side surface of the stirring tank 1 through fixing bolts. Thus, the stirring tank 1 and the mounting plate 15 can be assembled and connected together through the four groups of fixing blocks 16. Four groups of support rods 17 are symmetrically mounted on the bottom of the mounting plate 15. The bottom of the support rods 17 is lower than the bottom of the filtration tank 3. The four groups of support rods 17 can provide support for the whole device, making the filtration tank 3 in a suspended state;

[0025] Preferably, a pipe cap is installed on the top of the liquid injection pipe 9 to seal the liquid injection pipe 9. Through the two liquid injection pipes 9, sewage and the solvent for sewage treatment can be respectively introduced into the interior of the stirring tank 1. The bottom of the rotating shaft 11 is rotatably connected to the mounting seat 13. Three fixing rods 14 are installed on the side surface of the mounting seat 13. The side surface of the fixing rods 14 is fixedly connected to the inner side of the stirring tank 1. Thus, the rotating shaft 11 and the inner side of the stirring tank 1 form a rotating connection.

Through the handle, the sealing plate 4 and the filter plate 5 can be inserted and installed into the inside of the filtration tank 3 or withdrawn from the inside of the filtration tank 3. Sliding grooves adapted to the sliders 6 installed on both sides of the sealing plate 4 and the filter plate 5 are opened on the inner wall of the filtration groove inside the filtration tank 3 and the inner wall of the through groove. The sliders 6 are located in the sliding grooves, so as to play a role in stabilizing the sealing plate 4 and the filter plate 5, enabling the water pressure and impact force received on the sealing plate 4 and the filter plate 5 to be transmitted to the overall structure of the filtration tank 3, so that the sealing plate 4 and the filter plate 5 will not shake or other unstable situations occur. During the process of sewage mixing treatment, it is necessary to insert and install the sealing plate 4 on the top of the filtration groove. At this time, the top of the filtration tank 3 is in a closed state, so that sewage will not enter the filtration groove, so as to mix and treat the sewage through the mixing tank 1. After mixing is completed, the sealing plate 4 is pulled out to the right, and the top of the filtration groove will be in an open state. At this time, sewage will enter the filtration groove. The sewage can be filtered through the filter plate 5 inserted at the bottom of the filtration groove, so that the particulate matter in the sewage stays in the filtration groove, and the sewage solution can be discharged through the drain pipe 7 installed at the bottom of the filtration tank 3. A pipe cap is installed at the bottom of the drain pipe 7 to seal the drain pipe 7. After the sewage filtration is completed, the filter plate 5 can be pulled out to clean the filter plate 5. At this time, the impurities in the filtration groove can be discharged through the drain pipe 7. When it is necessary to clean the inside of the mixing tank 1 and the filtration tank 3, the two can be disassembled and cleaned separately. The overall structure of this device is designed as a detachable structure, which is convenient for assembly and cleaning.
