After no water drops, the positioning column 21 is taken out, the front water baffle 2 is flipped downward, the filter plate frame 41 in the combination frame 4 is taken out for replacement or cleaning, and then it can be inserted back to purify the water again.

[0021] In this embodiment, a drain port 11 is provided on the rear end face of the biofilter 1, and two sets of lifting screws 3 are symmetrically mounted on the left and right ends of the biofilter 1 through bearings; and the surfaces of the two sets of lifting screws 3 are connected with driving blocks 31.
