When the water nozzle sprays water to remove slag, the slag-containing wastewater falling from the wire mesh of the paper machine enters the return bucket. Under the action of the square filter bucket and filter screen, the slag-containing wastewater achieves secondary filtration. Then, it is filtered again by the cylindrical filter cover at the bottom of the water supply pipe and the activated carbon filter material filled inside. This satisfies the multi-stage filtration of slag-containing wastewater while facilitating recycling, thereby meeting the energy-saving and emission-reduction requirements of the paper machine.
