Embodiment 1

[0039] The present invention is a sewage treatment device based on 3D printing biological filler, which includes a cylinder made of plexiglass. The cylinder includes an inner chamber 2, a shell 1 and a cylinder cover. Both the inner chamber 2 and the outer shell 1 are cylinders, and the height and diameter The ratio is 3:1, and there are multiple exhaust holes on the cylinder cover. The inside of the inner chamber 2 is a reaction layer, and a water bath layer is formed between the inner chamber 2 and the outer shell 1 .

[0040] The filler 11 placed in the reaction layer has a structure of a three-dimensional hollow honeycomb-like sphere with 5 sides and a diameter of 30mm. And the filler 11 is made of plastic ultrafine spherical powder through 3D printing technology. The plastic ultrafine spherical powder adopts a size of 300 mesh. The prepared filler 11 sphere has a better surface roughness and a faster biofilm formation quick. The packing 11 is placed inside the cavity 2 in...

Abstract

The invention discloses a sewage treatment device based on 3D printing biological stuffing, and belongs to the field of water pollution government devices. The device comprises a barrel body, a stirring device, an aeration device and stuffing and the device further comprises a water bath machine and a water bath machine water inlet pump, wherein the two ends of the water bath machine are respectively connected with a water bath layer water inlet tube and a water bath layer water outlet tube; a water bath layer water inlet pump is arranged between the water bath machine and the water bath layer water inlet tube; the stuffing is vertically suspended between upper gridding and lower gridding; adjacent two rows of stuffing are arranged in a staggered manner at upper and lower layers, and the spacing between the adjacent two rows of the stuffing is equal; the lower gridding is matched with the inner edge of an inner cavity; the upper gridding is matched with the outer edge of the inner cavity. The device disclosed by the invention is high in stuffing film-suspending rate, high in sewage treatment load, capable of realizing automatic control and suitable for sewage treatment for domestic sewage such as household sewage, housing estate sewage or plant sewage and similar water quality, and is not blocked.

Description

technical field [0001] The invention belongs to the field of water pollution control devices, and in particular relates to a sewage treatment device based on 3D printing biological fillers. Background technique [0002] Due to the increasing development of industrial production and the rapid increase of population, my country's water resources are being polluted from various aspects such as production and life, so sewage treatment technologies and devices have emerged as the times require. Biofilm sewage treatment technology is a widely used sewage treatment technology. The essence of this technology is that bacteria and some microscopic organisms such as protozoa and metazoans grow and breed on the surface of the filler to form biofilm. The pollution in sewage The substances are degraded by the microorganisms in the biofilm, so that the sewage is purified. There are many types of traditional fillers, including fixed honeycomb fillers, corrugated plate fillers, porous biolo...
