The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
Specific examples are as follows:
example 1 as shown in fig. 1 to 3, a biochemical tank using a magnetic core suspended filler, the biochemical tank comprising a tank body 1 and an aeration device 17. The biochemical tank also comprises a magnetic suspension filler 4, a rotating magnetic field module 2 and a static magnetic field module 3.
The left side of the tank body 1 is provided with a water inlet pipe 11 near the upper end, and a water outlet hole 16 is arranged near the right side position and the upper end of the tank body 1 for water inlet and water outlet. An inspection manhole (not shown in the figure) is further arranged at the top of the tank body 1, so that the interior of the tank body 1 is convenient to observe and inspect.
The aeration device 17 is arranged at the bottom of the tank body 1 and is used for introducing air into the tank body 1 to supply oxygen.
The magnetic suspension filler 4 includes a magnetic core 41 and a bioadhesive body. The biological adhesion body is coated outside the magnet core 41 for adhesion of sludge containing active organisms. The magnetic suspension filler 4 is placed in the tank body 1, is suspended on the water surface under the condition of not attaching sludge, has basically the same density as sewage after attaching sludge, and is suspended in the water.
The magnetic field generated by the rotating magnetic field module 2 is continuously changed, so that the attractive force direction of the rotating magnetic field module 2 to the magnetic suspension filler 4 is also changed, the magnetic suspension filler 2 can be driven to move in sewage, the sewage is indirectly driven to generate vortex flow, the biochemical reaction is accelerated, the reaction time is shortened, and the sewage treatment efficiency is improved. In this embodiment, the rotating magnetic field module 2 may employ a rotating magnetic field assembly that drives the rotor to rotate, such as in a magnetic stirrer.
The rotating magnetic field is a magnetic field which is constant in size and rotates in space at a certain rotating speed, and is divided into a circular rotating magnetic field and an elliptical rotating magnetic field, wherein the circular rotating magnetic field and the elliptical rotating magnetic field are respectively rotating magnetic fields of which the tail ends of arrows of magnetic induction intensity vectors move along the circumference, the moving track of the tail ends of the magnetic induction intensity vectors is elliptical, and the circular rotating magnetic field is a basic condition for mutual conversion between electric energy and rotating mechanical energy, and the circular rotating magnetic field and the elliptical rotating magnetic field rotate around a fixed axis at a certain speed in space.
The magnetic field generated by the static magnetic field module 3 is kept unchanged all the time, and the magnetic attraction force with unchanged direction is kept for the magnetic suspension filler 4 so as to accelerate the sedimentation of the magnetic suspension filler, and further drive the flocculent sludge to be sedimented to the bottom of the tank body 1, thereby greatly reducing the sedimentation time. Experiments show that the whole sedimentation time can be shortened to more than 50 percent.
When the biochemical pond using the magnetic core suspended filler is used, the magnetic suspended filler 4 attached with the sludge is suspended in sewage, and the microbiota in the sludge reacts with and decomposes organic matters in the sewage, so that the purification of the water body is realized. Sewage enters the tank body 1 from the water inlet pipe 11, is purified by activated sludge in the tank body 1, and the aeration device 17 supplements oxygen for the sewage to provide conditions for biochemical reaction.
When sewage treatment starts, the rotating magnetic field module 2 is started, the rotating magnetic field module 2 drives the magnetic suspension filler 4 in sewage to move, the sewage is indirectly driven to generate vortex flow, the contact between the sewage and the sludge is increased, the biochemical reaction is accelerated, the reaction time is reduced, and the sewage treatment efficiency is improved. Meanwhile, compared with mechanical stirring equipment with strong shearing such as pumps and stirrers, flocculent sludge is easy to damage and the filler is easy to damage, the magnetic field is adopted to drive the filler to move and disturb sewage, so that the activity of the sludge can be effectively protected, the filler can be recycled by utilizing magnetism, and the cost is saved.
After biochemical reaction contacts, the rotary magnetic field module 2 is closed, the static magnetic field module 3 is started, a unidirectional magnetic field which is unchanged all the time is generated, the magnetic suspension filler 4 is kept to be attracted continuously, sedimentation of the magnetic suspension filler 4 is accelerated, the magnetic suspension filler 4 drags to drive the bottom of the flocculent sludge sedimentation value tank body 1, and sedimentation time is greatly shortened.
Further, the magnetic suspension filler 4 adopts a comet-type structure, and specifically further comprises a filament 42 and a plastic protective film shell 43. The plastic protective film case 43 covers the outside of the magnet core 41 and fixes the filament 42 outside the magnet core 41. The plastic protective film shell 43 is coated to permanently fix the filament 42 and the magnet core 41, and can prevent the magnet core 41 from being corroded, so that the service life is prolonged.
The comet type filler structure with the long fiber filaments 42 has huge specific surface area, greatly increases the sludge concentration in the reaction tank, and reduces the design tank capacity of the biochemical tank.
Further, the plastic protective film shell 43 is made of polyethylene, has good chemical stability and can resist most of acid and alkali.
Further, a horizontal porous partition plate 12 is provided in the cell body 1 near the bottom. The porous partition plate 12 isolates an upper space and a lower space, the magnetic suspension filler 4 is positioned above the porous partition plate 12, and settled sludge is positioned below the porous partition plate 12, so that the magnetic suspension filler 4 can be effectively prevented from entering the lower part of the porous partition plate 12.
In the embodiment, the aeration device 17 is arranged above the porous partition plate 12 to provide oxygen for the water body, so that the sewage purification is convenient.
Further, a sealing partition plate 13 is vertically arranged in the tank body 1 near the right side, two spaces are isolated in the tank body 1, namely a reaction treatment area 14 on the left side and a water outlet area 15 on the right side, and the communication between the reaction treatment area 14 and the water outlet area 15 is kept at the bottom of the sealing partition plate 13, so that the short flow phenomenon is effectively prevented.

Further, the prefilter module 5 includes a plurality of drawer-type filter bins and a residue bin cloth bag. The filter bins are sequentially arranged from top to bottom, and the hollow spaces of the filter bins are gradually reduced from top to bottom. The sewage to be treated is discharged into the uppermost filter bin, so that the sewage to be treated is filtered for a plurality of times by the filter bins, the solid impurities in the sewage to be treated can be better removed, and the filtered sewage enters the tank body 1 of the biochemical tank from the water inlet pipe. The residue bin cloth bag is arranged below the filter bin, solid impurities in the filter bin are poured into the residue bin cloth bag for collection after being accumulated to a certain degree, and the solid impurities in the residue bin cloth bag are treated regularly.
