s1, opening the air compression pump 4 on the compressed air conveying pipeline 2, preliminarily sweeping the loaded and unloaded residual liquid in the liquid conveying pipeline 1 into the residual liquid discharging pipeline 3, and flowing into a special residual liquid storage barrel;

s2, putting activated carbon into the crushing cabin 51, starting the motors on the main crushing cutter head 55 and the auxiliary crushing cutter head 56 to enable the main crushing cutter head 55 and the auxiliary crushing cutter head 56 to rotate, enabling the activated carbon to fall into the bottom of the crushing cabin 51 downwards along with the self gravity, crushing along with the rotation of the main crushing cutter head 55 at the bottom of the crushing cabin 51, enabling activated carbon particles to flow towards the side wall of the crushing cabin 51 under the action of the rotation of the main crushing cutter head 55 and to be crushed by the auxiliary crushing cutter heads 56 on the side wall of the crushing cabin 51, enabling the activated carbon particles to form a rotational flow in the crushing cabin 51 until the activated carbon particles are crushed into powder, screening activated carbon powder meeting the particle size requirement under the action of the filter screen 57, and enabling the activated carbon powder to obliquely fall into the infusion tube 1 from top to bottom through the inclined tube body;

and S3, leading the activated carbon powder to enter the liquid conveying pipe 1 along with the movement inertia of falling downwards in an inclined way, starting the air compression pump 4 again, leading the activated carbon powder in the liquid conveying pipe 1 to pass through the liquid conveying pipe 1 and enter the residual liquid discharge pipeline 3 along with the loading and unloading of a small part of residual liquid.
