Example Embodiment
[0038] Example 1
[0039] The present invention is a sewage treatment device based on 3D printing biological fillers, which includes a cylinder made of plexiglass. The cylinder includes an inner cavity 2, an outer shell 1 and a cylinder cover. The inner cavity 2 and the outer shell 1 are all cylinders with a height and a diameter. The ratio is 3:1, and the cylinder cover is provided with multiple exhaust holes. The inner cavity 2 is a reaction layer, and a water bath layer is formed between the inner cavity 2 and the outer shell 1.
[0040] The structure of the filler 11 placed in the reaction layer is a five-sided three-dimensional hollow honeycomb sphere with a diameter of 30 mm. Moreover, the filler 11 is made of plastic superfine spherical powder by 3D printing technology. The plastic superfine spherical powder adopts a size of 300 mesh. The prepared filler 11 has a better surface roughness and a higher biological coating speed. fast. The filler 11 is placed in the cavity 2 ...
