Sewage pool suspension cover plate and antifouling device

The invention relates to the technical field of high polymer materials and the technical field of interface chemistry, in particular to a sewage pool suspension cover plate and an antifouling device. The suspension cover plate comprises a suspension frame and a polar polyolefin sheet arranged in the suspension frame; the polar polyolefin sheet comprises a low-density polyolefin base material, a hydrophilic side group and a lipophilic side group, wherein the hydrophilic side group and the lipophilic side group are grafted on the surface of the low-density polyolefin base material; a plurality of special-shaped structures are arranged on the surface of the polar polyolefin sheet, the average size of each special-shaped structure is not smaller than 100 microns, and the height of each special-shaped structure is not larger than 20 microns; the surface grafting rate of the hydrophilic side group is 10-50%, and the surface grafting rate of the lipophilic side group is 10-50%. By adopting the suspended cover plate
