ozone gas is introduced into the inner cavity of the rotary water inlet centrifugal tube (16) through an ozone inlet tube (7), the ozone gas is primarily mixed with the water solution in a gas-liquid mixing cavity (15), the mixture enters the inner cavity of the centrifugal filtering container (10) through a water outlet hole (14), organic matters in the water solution are sufficiently oxidized and decomposed through the ozone gas, and insoluble products after partial organic matters are decomposed are flocculated into particles through a flocculating agent still remaining in the water body and are settled at the bottom of the centrifugal filtering container (10);
s4: opening an electromagnetic valve switch between the centrifugal filtering container (10) and the purified water collecting cavity (13), wherein the treated water solution in the centrifugal filtering container (10) enters the purified water collecting cavity (13) and is discharged outwards through a water discharging pipe (11); when the centrifugal filter container (10) has more flocculate settled, the sewage is discharged through a sewage discharge pipe (30).
