Equipment for preparing organic wastewater catalyst by using anode manganese slag

The invention relates to the technical field of solid waste treatment, in particular to equipment for preparing an organic wastewater catalyst by using anode manganese slag, the equipment comprises a grinding mechanism, and the grinding mechanism comprises a tray; the tray comprises a grinding part and a screening part; the grinding part is used for grinding anode manganese slag, and the screening part is used for screening the ground anode manganese slag; the tray can swing towards the grinding part or the screening part; when the tray swings towards the screening part, the anode manganese slag slides to the screening part along the tray, so that the small-particle anode manganese slag is screened out; when the tray swings towards the grinding part, the anode manganese slag slides to the grinding part along the tray, so that the large-particle anode manganese slag is ground again; and the tray swings in a reciprocating manner, so that the anode manganese slag is repeatedly ground and screened, continuous gri
