When adding new materials, the secondary feed hopper 63 of the filter material cleaning device 6 is lifted through the lifting push rod 65, and the secondary feed hopper is in butt joint with the filter material adding valve 11. Then the filter material cleaning device 6 is started and the filter material adding valve 11 is opened. The cleaned filter material enters the filter tank body 1 through the discharge chute 64 and the filter material return chute 12.

When the filter material of the filter tank is activated carbon, the filter tank has two functions of adsorption and filtration, the activated carbon can be adsorbed to reach a saturated state when used for a certain time, and the activated carbon filter material needs to be discharged out of the filter tank, namely the operation of waste discharge. When the filter chambers are multi-stage, only the first stage filter chamber has the operation of waste material discharge, and the waste material discharged from the next stage filter chamber is discharged to the previous stage and is the 'new material' of the previous stage.

When the waste is discharged, the filter material cleaning device 6 operates to the position of a filter chamber where the waste is required to be discharged, the electric push rod 57 pushes the hollow ejector rod 55 upwards to be in butt joint with the gas path butt joint valve 42, and compressed air is accessed into the equipment; the 'filter material cleaning/outward discharge switching valve 23' is opened to an outward discharge position, meanwhile, the filter material outward discharge valve 24 corresponding to the filter tank is opened, then the filter material lifting pipeline 17 descends, the pipe jacking 18 at the bottom end of the pipeline presses down and opens the deep water valve 28, then the air lifting air inlet valve 21 is opened, and the filter material is discharged out of the filter tank through the filter material lifting pipeline 17, the filter material cleaning/outward discharge switching valve 23, the outward discharge pipeline, the filter material outward discharge valve 24 and the filter material outward discharge pipeline 25.
