Description
Technical Field
The utility model relates to a biochemical sewage treatment device field of biomembrane especially relates to a spiral biological rotating disc sewage treatment plant.
Background
The biological rotating disc process is one biological sewage treating process with biological film process, and the treating process makes microbe, protozoan and other miniature animal grow and breed on the biological rotating disc stuffing carrier to form film biological sludge, i.e. biological film, and the microbe on the biological film absorbs the organic pollutant in sewage as nutrients to purify sewage. The core technology of the biological rotating disk is that the rotation of the rotating disk is utilized to lead the microorganisms attached on the rotating disk to circulate back and forth in water and air, thereby forming a continuous biological sewage treatment process of oxygen covering, adsorption, mass transfer and oxidative degradation. Wherein, the rotating disc is about 40 percent immersed in water and about 60 percent exposed in air, and the biological film on the disc mainly adsorbs new organic matters underwater and absorbs oxygen required by metabolism in air.
When the biological rotating disk in the prior art carries out biochemical sewage treatment, only about 40% of the space in the cavity of the device is filled with sewage, and about 60% of the space is exposed in the air, so that the occupied area of the whole device is large and the space utilization rate is low. In addition, the biomembrane on the existing biological rotating disc is continuously thickened along with the increase of the biocoenosis, the biomembrane falls off after being subjected to the action of shear stress to a certain degree, and a new biomembrane is regenerated, and the generation of the shear stress requires the biological rotating disc to keep a certain rotating speed, if the rotating speed can be reduced, the original purifying effect is kept, and the biological rotating disc has excellent significance for reducing energy consumption and prolonging the service life of equipment.
Disclosure of Invention
An object of the utility model is to overcome the not enough of above-mentioned technique, provide a spiral biological rotating disc sewage treatment plant, it is little to have solved former equipment space utilization, and area is big problem reduces the energy consumption when keeping original treatment effect, improves life.
The utility model adopts the technical proposal that: the utility model provides a spiral biological rotating disc sewage treatment plant, includes hollow barrel, sets up in the water inlet at barrel top, sets up in the delivery port at barrel bottom center, its characterized in that, coaxial arrangement has the carousel axle through motor drive in the barrel, and the epaxial carousel disc of installing the helical structure of downwardly extending of carousel, set up the air channel who link up along the axle center direction in the carousel axle, the air pump is connected to the air channel on carousel axle top.
In the operation process of the device, microorganisms attached to the turntable plate absorb organic pollutants in the sewage as nutrients to purify the sewage, dissolved oxygen required by microorganism metabolism is intermittently pumped into the air by the air pump to be supplied, and meanwhile, the turntable plate with the spiral structure enables water flow to generate a rotational flow effect in the rotation process, so that the shear stress is increased, and the turntable plate can cut off the biofilm only by maintaining a low speed.
Further, the lower part of the cylinder body is of a conical structure.
Furthermore, a filter screen is installed on the upper part of the conical cylinder body and used for filtering off fallen biological films.
Furthermore, a plurality of supporting bases are installed on the outer wall of the conical barrel body and used for arranging the barrel body.
The utility model has the advantages that: an external air pump is adopted for supplying oxygen, so that the biological rotating disk can be completely immersed in sewage, the floor area of equipment is reduced, and the space utilization rate is improved; the rotational flow effect of the spiral turntable plate is utilized to improve the shear stress and reduce the rotation speed of the biological turntable, thereby reducing the energy consumption and prolonging the service life.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: the device comprises a cylinder body 1, a water inlet 2, a water outlet 3, a motor 4, a rotary table shaft 5, a rotary table disk 6, an air channel 7, an air pump 8, a conical cylinder body 9, a filter screen 10 and a supporting base 11.
Detailed Description
Example 1
As shown in fig. 1, a spiral biological rotating disc sewage treatment device comprises a hollow cylinder 1, a water inlet 2 arranged at the top of the cylinder 1, and a water outlet 3 arranged at the center of the bottom of the cylinder 1, wherein a rotating disc shaft 5 driven by a motor 4 is coaxially arranged in the cylinder 1, a rotating disc plate 6 of a downward extending spiral structure is arranged on the rotating disc shaft 5, a through air channel 7 is arranged in the rotating disc shaft 5 along the axis direction, and the air channel 7 at the top end of the rotating disc shaft 5 is connected with an air pump 8.
Wherein, the lower part of the cylinder body 1 is a conical structure, and the upper part of the conical cylinder body 9 is provided with a filter screen 10 for filtering out fallen biological membranes; the outer wall of the conical barrel 9 is also provided with a plurality of supporting bases 11 for arranging the barrel.
In the operation process of the device, microorganisms attached to the turntable plate absorb organic pollutants in the sewage as nutrients to purify the sewage, dissolved oxygen required by microorganism metabolism is intermittently pumped into the air by the air pump to be supplied, and meanwhile, the turntable plate with the spiral structure enables water flow to generate a rotational flow effect in the rotation process, so that the shear stress is increased, and the turntable plate can cut off the biofilm only by maintaining a low speed.
