The invention discloses a water treatment filtering device and a use method thereof, relates to the related field of water treatment filtering, and aims to solve the problems that in the prior art, flocculent precipitate is generated when a flocculating agent is added into sewage, so that treated water needs to be discharged firstly, then the flocculent precipitate is discharged, and a backwashing step needs to be performed after the flocculent precipitate is completely discharged; the backwashing water can enter a treatment water tank, flocculent precipitates in a flocculation tank cannot be completely cleaned, and the demand quantity of the backwashing water is large. A middle partition plate is fixedly welded to the upper end in the filter shell, a treatment cavity is formed along the lower end of the middle partition plate, an outer sealing assembly is arranged at the lower end in the treatment cavity, and a filter assembly is arranged in the outer sealing assembly. The outer sealing assembly comprises a
