[0066] At this time, the servo motor 6 is started, and the servo motor 6 drives the first lead screw 423 through the transmission structure 26, and drives the second lead screw 71 on the output end, the first lead screw 423 drives the first sliding block 424 to move, the first sliding block 424 drives the moving plate 422 to move continuously, when the clamping block 4221 on the moving plate 422 is misaligned with the drain hole 4211 on the fixed plate 421, the water body can continue to flow into the bottom layer 24, and the sediment is retained on the filter membrane 41, when the second lead screw 71 rotates, the second sliding block 72 slides, the second sliding block 72 drives the placing frame 261 located above to move downward in the through opening 25 through the connecting plate 73, which drives the stirring structure 44 to move downward, and when the cleaning rod 443 abuts against the filter membrane 41, the servo motor 6 is turned off.

[0067] After waiting for the water body to enter the bottom layer 24 completely, the driving motor 43, the ozone generator 51 and the air pump 52 are started, the driving motor 43 drives the cleaning rod 443 to clean the filter membrane 41, the air pump 52 sends the ozone generated by the ozone generator 51 into the bottom layer 24 through the gas conveying pipe 53, and the ozone is mixed with the water body for the last disinfection treatment, and after the disinfection treatment is completed, the water body can be discharged from the water outlet 29.

[0068] During the disinfection waiting process, the moving block 2152 can be pushed to slide in the sliding groove 214, and the moving block 2152 drives the baffle 2151 to slide in the moving groove 211, when the bottom of the baffle 2151 is misaligned with the waste discharge opening 213, the limiting block 2155 is rotated, the limiting block 2155 drives the rotating rod 2154 to rotate to below the moving block 2152, the moving block 2152 lifts and fixes the baffle 2151, and the waste discharge opening 213 is always in an unobstructed state, and at this time, the sediment is discharged from the waste discharge opening 213 under the action of the cleaning rod 443.
