The movement of the displacement rod drives the adsorption plate to move and rotate to adsorb the petrochemical wastewater inside the adsorption cylinder.

At the same time, the filter plate shakes upward and hits the protrusion to generate vibration. The vibration of the filter plate can loosen the solid particles deposited on the filter plate and suspend them in the water, thereby reducing the blockage of the filter plate, extending the filtration cycle, and further improving the efficiency of subsequent adsorption.
