and 5: after the dephosphorization reaction and sedimentation of the paper pulp wastewater in the No. 1 treatment tank (3) are completed, the paper pulp wastewater at the top in the No. 1 treatment tank (3) flows into the No. 2 treatment tank (4) to complete solid-liquid separation, solid pollutants in the paper pulp wastewater accumulate at the bottom of the inner wall of the No. 1 treatment tank (3) to form sludge, and a sludge pump (19) is matched with a sludge pipe (20) to clean the sludge at the bottom of the inner walls of the No. 1 treatment tank (3) and the No. 2 treatment tank (4);

step 6: the pulp wastewater in the No. 2 treatment tank (4) is subjected to sun exposure treatment, and the pulp wastewater in the No. 2 treatment tank (4) enters the No. 3 treatment tank (5);

and 7: the biomembrane filter (5 a) in the No. 3 treatment pool (5) filters the effluent of the No. 2 treatment pool (4), and the lift pump (5 b) and the water outlet pipe (5 c) are matched to transfer the treated water to the outer side of the device.
