A plurality of stirring rods 23 are fixedly connected to the surface of the rotating shaft 22 at equal intervals around the circumference. A water inlet pipe 12 and a medicine adding pipe 13 are respectively communicated with both sides of the flocculation tank 1. A discharge pipe 14 is communicated with the surface of the flocculation tank 1 and at the bottom of the medicine adding pipe 13.

[0020] Furthermore, for the convenience of water-saving cleaning of the flocculation tank 1, a mounting plate 3 is movably connected inside the flocculation tank 1. A gear ring 4 is rotatably connected inside the mounting plate 3 through a bearing. A first driving motor 5 is fixedly connected to the top of the mounting plate 3 through a bracket. A gear 6 meshing with the gear ring 4 is fixedly connected to the surface of the output shaft of the first driving motor 5.
