It improves the pollutant degradation performance by optimizing the fluid flow state and mass transfer efficiency.

[0003] The Chinese patent with announcement number CN102126786B discloses a cyclone-type aerobic granular sludge reactor; it includes an inner tube, an outer tube, a cyclone blade, an aerator and a cyclone aeration device. The cooperation of the aerator and the cyclone aeration device allows the body and the mud-water mixture to spirally rise inside the inner tube to the outer tube, and spiral down under the action of the cyclone blade inside the outer tube.

DETAILED DESCRIPTION

[0031] Example 1, as Figure 1-Figure 5 As shown, the present invention proposes a cyclone-type aerobic granular sludge reactor for water pollution treatment, comprising a reaction mechanism, a combining mechanism and a recovery mechanism;

[0032] The reaction mechanism includes a tank body 1, a central tube 15, spiral blades 14, a pump body 6, and an aeration assembly; the central tube 15 is provided inside the tank body 1; the spiral blades 14 are provided on the central tube 15 and connected to the inner wall of the tank body 1; the aeration assembly is provided on the tank body 1 for aerating the sewage in the tank body 1; a water inlet pipe 7 is provided near the top of the tank body 1; the pump body 6 is provided on the tank body 1 and connected to the central tube 15;

[0033] It should be noted that the water inlet pipe 7 is connected to the delivery pump for conveying sewage from the outside; the sewage enters the tank body 1 through the water inlet pipe 7 and flows downward along the spiral blade 14. During the flow, under the action of centrifugal force, the aeration component continuously aerates the tank body 1, which not only supplies oxygen to the aerobic bacteria in the aerobic granular sludge, but also breaks up the sludge, impurities and aerobic granular sludge that are gathered together, thereby continuously changing the distribution of the aerobic granular sludge, making it easier for the aerobic granular sludge to fully degrade the soluble organic matter in the sewage; when the sewage flows to the end of the spiral blade 14, the water outlet 101 on the tank body 1 is discharged into the box body 3, and then under the action of the pump body 6, the central pipe 15 is cooperated to pump the sewage back to the top of the tank body 1, and the above treatment process is repeated to realize the sewage circulation treatment function.

[0034] The combination mechanism comprises a box 10, a vibration assembly and a telescopic part 9; the box 10 is arranged on the water inlet pipe 7, and a discharging groove is formed at the top end of the box 10; Fe3O4 nanoparticles are stored in the discharging groove; a combination groove is formed in the box 10, and the combination groove is used for combining the aerobic granular sludge and the Fe3O4 nanoparticles; an opening is formed in the box 10 and communicates with the combination groove, the vibration assembly is arranged on the inner side of the opening, and the vibration assembly is used for driving the aerobic granular sludge to vibrate, so that the aerobic granular sludge is in full contact with the Fe3O4 nanoparticles; the telescopic part 9 is arranged on the box 10 and connected with the vibration assembly, the telescopic part 9 comprises but is not limited to a pneumatic cylinder and the like, and the telescopic part 9 can drive the vibration assembly to move out of the combination groove, so that the aerobic granular sludge can fall into the quantitative groove in the discharging roller b20; the top end of the box 10 is provided with a box cover 11, and the Fe3O4 nanoparticles can be supplemented into the discharging groove by opening the top cover; the discharging groove is in communication with the combination groove, and the discharging roller a19 is rotationally connected to the communication position; the combination groove is in communication with the water inlet pipe 7, and the discharging roller b20 is rotationally connected to the communication position, and the discharging roller b20 extends to the inner side of the water inlet pipe 7; a plurality of strip-shaped grooves are formed in the surface of the discharging roller b20, and the strip-shaped grooves are used for increasing the friction force between the discharging roller b20 and the sewage; a plurality of circumferentially distributed quantitative grooves are formed in the outer circumferential surfaces of the discharging roller a19 and the discharging roller b20; the box 10 is provided with a motor b25; the output end of the motor b25 is connected with the discharging roller a19.

[0035] It should be noted that the Fe3O4 nanoparticle dosage concentration is usually 10-200 mg / L; the particle size is selected to be 10-100 nm (small particle size is more easily adsorbed by EPS); the Fe3O4 nanoparticles can be used as a “skeleton” for microbial adhesion, promote the close combination of bacteria-bacteria and bacteria-EPS, and enhance the mechanical strength of the aerobic sludge particles, so that the aerobic sludge particles are not easy to disintegrate under high shear force (such as aeration and stirring).

[0036] It should be noted that the combination mode of the Fe3O4 nanoparticles and the aerobic granular sludge is that the extracellular polymeric substance (EPS) (such as protein and polysaccharide) of the aerobic granular sludge has a negative charge (-COOH, -OH, etc.), and the surface of the Fe3O4 nanoparticles has a positive charge (Fe 3+ ), and the Fe3O4 nanoparticles can be combined through electrostatic adsorption and van der Waals force.

[0037] It should be noted that the discharge roller a19 is driven to rotate intermittently by the motor b25, so that the quantitative groove of the discharge roller a19 facing the lower feed trough is rotated to face the combining groove. During this process, the Fe3O4 nanoparticles can be transported to the combining groove. Under the action of the vibration component, the aerobic sludge particles are fully in contact with the Fe3O4 nanoparticles. After the combination is completed, the telescopic component 9 is used to drive the vibration component to move out of the combining groove, so that the aerobic sludge particles fall into the quantitative groove on the discharge roller b20. When the sewage flows into the water inlet pipe 7, the sewage will drive the discharge roller b20 to rotate, so that the quantitative groove facing the combining groove is rotated to face the inside of the water inlet pipe 7. During this process, the aerobic sludge particles can be transported to the water inlet pipe 7 and then enter the sewage.

[0038] The recovery mechanism includes a bottom plate 17, a surrounding plate 2, a diversion assembly, a magnetic part a12 and a box body 3; a water outlet 101 is provided on the outer peripheral surface of the tank body 1 near the bottom end; the bottom plate 17 is provided on the tank body 1 near the water outlet 101, and baffles are connected at both ends of the bottom plate 17; one side of the baffle divides the water outlet 101 into a clean water area and a sludge area; the diversion assembly is provided in the sludge area; the box body 3 is detachably connected to the bottom end of the surrounding plate 2; the surrounding plate 2 is connected to the bottom plate 17; the magnetic part a12 is provided at the bottom end of the box body 3, and the magnetic part a12 includes but is not limited to an electromagnet, and the diversion assembly includes a diversion plate 16 and a motor a18; the diversion plate 16 is rotatably provided in the sludge area; the motor a18 is provided at the bottom end of the tank body 1 and its output end is connected to the diversion plate 16; the surrounding plate 2 is provided on the ground through a support part for supporting the tank body 1; a pipe a13 for extracting clean water is provided on the surrounding plate 2.

[0039] It should be noted that, when the sewage is being treated, the diverter plate 16 is kept closed, that is, the diverter plate 16 realizes the closing function of the sludge area (refer to Figure 5 ); Sewage can only be discharged into the box body 3 through the clean water area of ​​the water outlet 101; when the sewage treatment is completed and the aerobic sludge particles are recovered, the motor a18 is used to drive the diverter plate 16 to rotate 40 °, and at this time, one end of the diverter plate 16 contacts the enclosure 2 while the sludge area of ​​the water outlet 101 is opened (reference Figure 3 and Figure 4 ), and then close the aeration assembly. As the sewage spirally flows downward along the spiral blades 14, the impurities and sludge in the sewage gather together under the action of centrifugal force and flow along the inner wall of the tank body 1. When the sewage flows to the water outlet 101, the gathered sludge and impurities pass through the sludge area under the guidance of the diverter plate 16 and flow to the bottom plate 17, and the clean water passes through the clean water area of ​​the water outlet 101 into the box body 3, realizing the rapid sedimentation and separation function of impurities and sludge in the sewage without waiting for its natural static sedimentation, thereby significantly improving the sewage treatment efficiency.

[0040] It should be noted that the magnetic component a12 can magnetically attract aerobic sludge particles combined with Fe3O4 nanoparticles, thereby realizing the function of separate recovery of aerobic sludge particles.

[0041] Example 2, as Figure 6-Figure 7 As shown, the present invention proposes a cyclone aerobic granular sludge reactor for water pollution treatment. Compared with Example 1, this embodiment also introduces in detail the structure of the vibration component, which includes a shell 26, a plate a21, a spring 23, a vibration motor 22 and a magnetic part b24; the shell 26 is slidably connected to the opening, and the shell 26 is connected to the telescopic part 9; the plate a21 is slidably arranged on the inner side of the shell 26 and is connected to the shell 26 through the spring 23; the vibration motor 22 is arranged on the plate a21; the magnetic part b24 is arranged on the inner side of the shell 26, and the magnetic part b24 includes but is not limited to an electromagnet.

[0042] It should be noted that the vibration motor 22 drives the plate a21 to vibrate up and down, and the spring 23 will intensify the vibration of the plate a21, helping the Fe3O4 nanoparticles to be fully mixed with the aerobic granular sludge. The magnetic field generated by the magnetic part b24 makes the Fe3O4 nanoparticles arranged in a directional manner to form a "magnetic skeleton", which promotes the close aggregation of sludge microorganisms.

[0043] Example 3, as Figure 8 As shown, the present invention proposes a cyclone aerobic granular sludge reactor for water pollution treatment. Compared with the second embodiment, this embodiment also includes a piston tube 8 provided on the side wall of the tank body 1; a piston block 801 is provided on the sliding inside the piston tube 8; and a piston rod 802 is connected to the piston block 801.

[0044] It should be noted that by pulling the piston block 801 to move in the piston tube 8 through the piston rod 802, part of the flowing sewage, sludge and impurities can be sampled to detect whether there is still aerobic granular sludge inside. When the sample does not contain aerobic granular sludge, it means that the aerobic granular sludge has been completely recovered; at the same time, the samples taken out can also be used to detect the treatment status of organic matter in the sewage, thereby judging the progress of sewage treatment.

[0045] Example 4, as Figure 1-Figure 3 As shown, the present invention proposes a cyclone aerobic granular sludge reactor for water pollution treatment. Compared with Example 3, this embodiment also introduces in detail the structure of the aeration component, which includes an air pump 4, a pipeline structure 5 and an aeration valve; a plurality of holes are opened on the side wall of the tank body 1 from top to bottom; the aeration valve is arranged on the inside of the hole; the air pump 4 is arranged on the support part and is connected to the aeration valve through the pipeline structure 5; the pipeline structure 5 includes a ring tube and a vertical pipe; the vertical pipe is connected to the aeration valve; the ring tube is connected to the vertical pipe and is also connected to the air pump 4.

[0046] It should be noted that the air pump 4 continuously delivers gas to the inside of the ring tube, the ring tube delivers the gas to the vertical pipes at various locations, and then the vertical pipes deliver the gas to the aeration valve, and finally the gas is ejected through the aeration valve to achieve the function of continuous aeration into the tank body 1.

[0047] In summary, when the present invention is used, the box cover 11 is opened, and the aerobic sludge particles are poured into the discharge trough. The discharge roller a19 is driven to rotate by the motor b25. When the quantitative groove of the lower trough above the lower roller a19 rotates to face the combining groove, the aerobic sludge particles inside it are poured into the combining groove and fall on the plate a21. When all the aerobic sludge particles in the lower trough are poured into the combining groove, the Fe3O4 nanoparticles are poured into the discharge trough while keeping the discharge roller a19 rotating. At this time, the Fe3O4 nanoparticles can be poured into the combining groove and fall on the plate a21, and then The vibration motor 22 is turned on, and the vibration motor 22 drives the plate a21 to vibrate. Under the action of the spring 23, the vibration of the plate a21 can be intensified to ensure that the aerobic sludge particles are in full contact with the Fe3O4 nanoparticles; at the same time, the magnetic part b24 is turned on, and the magnetic part b24 generates a magnetic field, so that the Fe3O4 nanoparticles are oriented and form a "magnetic skeleton", which promotes the close aggregation of sludge microorganisms, realizes the combination function of Fe3O4 nanoparticles and aerobic sludge particles, and enhances the mechanical strength of the aerobic sludge particles, making it difficult to disintegrate under high shear force conditions (such as aeration and stirring).

[0048] After the combination is completed, the water inlet pipe 7 is connected to the delivery pump for conveying sewage, and the delivery pump conveys the sewage to the inside of the water inlet pipe 7. During the flow of water, it will drive the discharge roller b20 to rotate (a plurality of strip grooves are provided on the surface of the discharge roller b20 to increase the friction between the discharge roller b20 and the sewage). The rotation of the discharge roller b20 causes the quantitative tank facing the combination tank to rotate to face the water inlet pipe 7, so that the aerobic sludge particles in the combination tank fall into the sewage. Since the quantitative tank conveys a certain amount each time, the aerobic sludge particles are conveyed to the sewage in multiple batches, which facilitates the uniform distribution of the aerobic sludge particles in the sewage; when the sewage enters the tank body 1, the sewage flows downward along the spiral blade 14, and the air pump 4 is turned on at the same time. The air pump 4 continuously conveys gas to the aeration valve to aerate the tank body 1. Aeration can not only supply oxygen to the aerobic bacteria in the aerobic granular sludge, but also break up the sludge, impurities and aerobic granular sludge that are gathered together, so as to continuously change the distribution of the aerobic granular sludge, so as to facilitate the aerobic granular sludge to fully degrade the soluble organic matter in the sewage; when the sewage flows to the end of the spiral blade 14, the water outlet 101 on the tank body 1 is discharged into the box body 3 at the same time, and then the sewage is pumped back to the top of the tank body 1 under the action of the pump body 6 and the central pipe 15, and the above treatment process is repeated to realize the recycling treatment function of the sewage; the piston rod 802 pulls the piston block 801 to move in the piston tube 8, so that part of the flowing sewage, sludge and impurities can be sampled, and the treatment status of organic matter in the sewage can be detected, so as to judge the treatment progress of the sewage.

[0049] After sewage treatment is completed, the magnetic member a12 at the bottom end of the box body 3 is opened. The magnetic member a12 can magnetically attract the aerobic sludge particles combined with Fe3O4 nanoparticles (Fe3O4 nanoparticles have magnetic properties). When the sewage carrying aerobic sludge particles and other impurities enters the box body 3, under the action of magnetic attraction, the aerobic sludge particles quickly settle and are magnetically adsorbed at the bottom end inside the box body 3. When the pump body 6 re-pumps the sewage and other impurities, the aerobic sludge particles will remain in the box body 3 to complete the recovery, achieving the function of separate recovery of aerobic sludge particles, avoiding the problem that free suspended solids (such as fibers) in the sewage wrap the surface of the aerobic granular sludge to hinder mass transfer or induce filamentous bacteria to swell, and avoiding the problem that part of the impurities (such as microplastics, colloids, and other organic matter) are embedded in the inside of the granules to interfere with microbial metabolism. Such a process is repeated 2-3 times to complete the recovery of the aerobic sludge particles. By pulling the piston block 801 in the piston tube 8 with the piston rod 802, part of the flowing sewage, sludge, and impurities can be sampled (by pulling the piston block 801 out of the piston tube 8, the piston tube 8 can be opened to take out the sewage and impurities extracted therein), and by detecting whether the sample contains aerobic sludge particles, it can be determined whether the aerobic sludge particles have been completely recovered.

[0050] After the aerobic sludge particles are completely recovered, the shunt plate 16 is rotated by 40° by the motor a18, at which time one end of the shunt plate 16 abuts against the surrounding plate 2, and the sludge area of the water outlet 101 is opened (refer to Figure 3 and Figure 4 ), and the air pump 4 is closed to stop aeration into the tank body 1. Since the sewage flows downward along the spiral blades 14, under the action of centrifugal force, the impurities and sludge in the sewage are aggregated together and flow along the inner wall of the tank body 1 (at this time, the aggregated impurities and sludge and the clarified sewage are in a stratified state). When the sewage flows to the water outlet 101, the aggregated sludge and impurities flow through the sludge area to the bottom plate 17 under the guidance of the shunt plate 16, and the clear water (clarified sewage) flows through the clear water area of the water outlet 101 into the box body 3, achieving the function of rapid settling and separation of impurities and sludge in the sewage, without the need to wait for natural static settling, significantly improving the efficiency of sewage treatment.

[0051] By connecting the pipe a13 on the surrounding plate 2 to an external water pump, the clear water in the box body 3 can be pumped out. Then the box body 3 is removed from the surrounding plate 2, and then the magnetic member a12 is closed, so that the aerobic sludge particles in the box body 3 can be recovered. The sludge and other impurities recovered on the bottom plate 17 can be taken out for recovery by using a shovel or other tools.

[0052] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
