S8, performing aeration operation in the filter tank (24), namely starting a fan unit (81) to enable the output end of the fan unit (81) to output for performing aeration operation in the filter tank (24), performing aeration operation in the filter tank (24) in a large area by arranging an aeration pipeline (84) in an I shape, further increasing the gas outlet efficiency of the gas by arranging an aeration head (85) in a shape with a narrow upper part and a wide lower part, generating enough stirring and mixing effect, promoting the circulation flow of water, maintaining a certain movement speed of the mixed liquid, and keeping the rest sludge in a suspension state in the mixed liquid all the time so as to further improve the disinfection efficiency of chlorine dioxide during reaction;

S9, collecting the liquid in the filter tank (24), namely starting a fifth suction pump (93) to enable the output end of the fifth suction pump (93) to output so as to be used for sucking the liquid in the filter tank (24) into a collecting barrel (91).
