The invention discloses a point-source pollution aeration treatment method. A screen-shaped trash rack box body is fixed on a riverbed around a sewage discharge hole so that the opposite side and both sides of the sewage discharge hole are enclosed by the trash rack box body; the bottom of the trash rack box body is provided with a multi-point aeration tank connected with an air pump, the multi-point aeration tank is provided with a plurality of air holes, and the bottoms of the air holes are mutually communicated by inner pipes; 10 to 20 layers of high-density pluriciliate polymer films are hung at the upper part of the trash rack box body, and the multi-point aeration tank can uniform aeration in a water body to enhance the treatment effect; a sewage flow passes by the high-density pluriciliate polymer films, and a point-source pollution aeration treatment device is fixed on the riverbed so that the front side and both sides of the sewage discharge hole are enclosed by the trash rack box body; and the disch
