[0026] Among them, as Figure 1As shown, a spiral tube 7 is connected below the annular tube 6. After the flocculant enters the annular tube 6 from the feed pipe 8, the flocculant in the annular tube 6 and the sewage enter the spiral tube 7 together. During this period, the flocculant is fully mixed in the sewage, which is beneficial to improving the subsequent sedimentation efficiency of the sewage.

[0027] Among them, as Figure 1 shown, a stirring rod 11 is inserted through the upper part of the tank body 1. A limiting plate 12 is fixedly connected to the stirring rod 11, and the limiting plate 12 is stuck above the tank body 1; a bracket 13 is supported on the stirring rod 11, and the bracket 13 is fixedly connected to the inner wall of the sedimentation tank 3; stirring impellers 14 are arranged around the stirring rod 11; a pulley A15 is installed at the top of the stirring rod 11, a belt 16 is wound around the pulley A15, and a pulley B17 is also wound around the belt 16.

[0030] The specific usage method and function of this embodiment:

[0031] In the present utility model, sewage is injected into the tank body 1 through the water inlet pipe 24, and the water level in the tank body 1 continuously rises. When the sewage passes through the filter plate 4 in the gap between the tank body 1 and the sedimentation tank 3, some contaminants in the sewage are intercepted by the filter plate 4 and remain in the filter tank. When the water level reaches the top of the tank body 1, the sewage enters the annular pipe 6 through the connecting pipe 5. The pressure pump 9 is turned on, and the flocculant stored in the storage tank 10 enters the annular pipe 6 through the feed pipe 8. The flocculant in the annular pipe 6 and the sewage enter the spiral pipe 7 together for mixing and then are injected into the sedimentation tank 3. The motor A 18 is turned on, and the stirring rod 11 is driven to rotate through the pulley B 17, the belt 16 and the pulley A 15, driving the stirring impeller 14 to stir the sewage in the sedimentation tank 3, accelerating the chemical reaction between the sewage and the flocculant. After a period of time, the stirring stops and sedimentation begins. During this period, the sediment generated by the sewage and the flocculant in the sedimentation tank 3 falls into the sewage storage tank 21 through the dirt dropping hole. After sufficient sedimentation time, the motor B 26 is turned on, and the baffle plate A 28 is driven to rotate through the rotating shaft 25, causing the dirt dropping holes of the baffle plate A 28 and the baffle plate B 29 to be misaligned, and the sedimentation tank 3 and the sewage storage tank 21 are isolated into independent spaces by the baffle plate A 28 and the baffle plate B 29. The solenoid valve B 33 is opened, and the sewage sediment in the sewage storage tank 21 is discharged through the sewage discharge pipe B 32, and the purified water in the sedimentation tank 3 is pumped out through the water outlet pipe 20.
