A high load VBF for treating rural dispersed sewage relates to a sewage treatment device. The VBF is cylindrical in shape, and is composed of an inlet pipe (1), a rotating distributor (2), a first VBF layer (3), a spacing layer (4), a second VBF layer (5), the spacing layer (4) and a sedimentation tank (6) from top to down; the VBF layers are sequentially provided with a grating floor (10), the aperture of which is 6-12meshes and which is consolidated with the inner wall of the VBF, a filter gauze (9) with the aperture of 2-4mm and light shale spherical porcelain granules (7) with the packingheight of 30-100cm, the diameter of 3-7mm and the density of 1.56*10<3>kg/m<3> from down to top, 15-28 thousand pieces of Eisenia foetida (8) are distributed on the surface of each square meter filling material. The spacing layer (4) is provided with a vent (11), the upper part of the sedimentation tank is provided with an overflow outlet tube (13) and the bottom is provided with a sludge discharging tube (12). The invention is characterized by reasonable structure, large hydraulic load, little occupied land area, no blockage as well as low engineering manufacture cost and operating cost, andcan be widely used for treating rural sewage.
