Embodiment 1

[0029] see figure 1 As shown, this embodiment provides a biofilm carrier 10 . The biofilm carrier 10 includes a magnetic carrier 11 made of a magnet or a magnetically permeable material, which is used for the attachment of microorganisms to form a biofilm, and is used to magnetize the water film on the surface of the biofilm. The magnetic carrier 11 is arranged on the disc of the biological turntable or directly serves as the disc of the biological turntable.

[0030] As an example, the magnets can be ferrite, rare earth magnets, alnico, iron carbon aluminum, etc., and the magnetic permeable materials can be pure iron, low carbon steel, iron-silicon alloys, iron-aluminum alloys, Nickel-iron alloys, iron-cobalt alloys, etc. When the magnetic carrier 11 is used to be installed on a disc, it can be made into a smaller block or sheet; when the magnetic carrier 11 is used directly as a disc, it can be made into a circle with a diameter of 1m to 3m. Disc. In this embodiment, the...

Embodiment 2

[0034] see figure 2 and image 3 As shown, this embodiment provides a disc 20 for sewage treatment. The disc 20 includes a skeleton 21 on which the biofilm carrier 10 described in Embodiment 1 is disposed.

[0035] When in use, the skeleton 21 is driven by the biological turntable driving device to rotate, and the biofilm carrier 10 on the skeleton 21 contacts with sewage and air alternately. see figure 2 As shown, as an example, the skeleton 21 can be a disc-shaped structure with a diameter of 1 m to 3 m, the biofilm carrier 10 is a relatively small plate, and several pieces of biofilm carriers 10 are densely distributed on the skeleton vertically or obliquely. 21, the connection method can adopt welding process. see image 3 As shown, as another example, the skeleton 21 is a dendritic structure centered on the rotation axis of the biological turntable and radiates outward. The width of the dendritic structure is 1m to 3m. The biofilm carrier 10 is For smaller sheets,...

Embodiment 3

[0038] see Figure 4 and Figure 5 As shown, this embodiment provides a disk 20 for sewage treatment, and the disk 20 includes the technical features described in Embodiment 2. In addition, the disc 20 in this embodiment further includes at least one first magnet 22 for providing a magnetic source for the biofilm carrier 10 . As an example, the first magnet 22 may be ferrite, rare earth magnet, alnico, iron carbon aluminum and so on. The magnetic carriers 11 of a plurality of biofilm carriers 10 are all made of magnetically permeable materials. As an example, the magnetically permeable materials can be selected from pure iron, low carbon steel, iron-silicon alloys, iron-aluminum alloys, nickel-iron alloys, Iron-cobalt alloys, etc. The biofilm carrier 10 is connected to the biofilm carrier 10 through a magnetic wire 23 , and the biofilm carrier 10 is connected to the first magnet 22 through the magnetic wire 23 . The first magnet 22 passes through the magnetic wire 23 to ma...

Abstract

The invention provides a biological membrane carrier applied to sewage treatment. The biological membrane carrier comprises a magnetic carrier and a water membrane, wherein the magnetic carrier is prepared from a magnet and a magnet-conduction material; the water membrane is used for forming the biological membrane by microorganism adhesion, and is used for magnetizing a water membrane on the surface of the magnetic biological membrane; the magnetic carrier is arranged on the disk of the biological rotary disk, or is indirectly taken as the disk of the biological rotary disk. The biological membrane carrier is applied to the disk, the disk is applied to the biological rotary disk; during use, the biological membrane carrier rotating out of a contact reaction groove can be used for magnetizing the water membrane, dissolved oxygen in the magnetized water membrane is increased greatly, the microorganisms can be subjected to a full aerobic reaction, sewage treatment performance is improved, a part of organic matters can be mineralized, the absorption rate of water to light is increased, and the solubility of inorganic salt is improved through the magnetization of a water body, the growth of alga is facilitated, and removing performance is improved specific to element N and P, heavy metal elements and small particles.

Description

technical field [0001] The invention relates to the technical equipment field of sewage treatment, in particular to a biofilm carrier, a disc and a biological turntable for sewage treatment. Background technique [0002] Biological turntable is a kind of equipment that uses biofilm method to realize sewage treatment, mainly including disc, rotating shaft, driving device and contact reaction tank. When working, the disk is partly immersed in the contact reaction tank filled with sewage, driven by the driving device, the rotating shaft drives the disk to rotate continuously. The turntable is alternately in contact with sewage and air, and after a period of rotation, a layer of biofilm will be attached to the disk. The part where the disc turns out of the reaction tank is in contact with the air, and the air continuously dissolves into the water film to increase its dissolved oxygen; the part where the turntable turns into the sewage, the biofilm absorbs the organic pollutants...
