[0009] Preferably, the second flocculation mechanism has the same structure as the first flocculation mechanism, and the second flocculation mechanism and the first flocculation mechanism are located between the output water pipe and the input water pipe.

[0010] Preferably, the first flocculation mechanism includes a water inlet pipe, a water pump module, a servo motor module, a transverse pipe, a nozzle, a fixing frame, a vertical rod, a connecting rod, a spiral strip, a ring seat and a fan blade.
