Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage treatment, in particular to a microparticle biochemical high-efficiency sewage treatment integrated device. BACKGROUND

[0002] Biochemical sewage treatment is a process of degrading organic matter and pollutants in wastewater through biochemical reactions by using the metabolic action of microorganisms, for example, the patent with publication number CN118619446B discloses a microbial sewage treatment device. The invention sets up a pressurizing assembly and a nozzle. When the microbial carrier bin is rotating, the microorganisms in the microbial carrier bin are pressurized and delivered to the nozzle by the pressurizing assembly, and the one-way valve assembly is triggered to act at the same time. At the same time, the air delivery assembly delivers air into the fixed bin, so that the air and the microorganisms are delivered together from the one-way valve assembly to the mouth of the nozzle. The air enters the sewage to form small air bubbles, which wrap the microorganisms and enter the sewage. The small air bubbles are easily broken by the pressure of the sewage, so that the microorganisms can be dispersed in multiple areas below the sewage surface, increasing the microorganism content in unit volume of sewage and improving the treatment efficiency of the sewage. In existing sewage treatment devices, microparticles are used as biological carriers and placed in the sewage treatment device to treat sewage. Microparticles usually have a large specific surface area, which can increase contact with pollutants in the sewage, promote physical processes such as adsorption and sedimentation, and also help the attachment of biofilm, improving the treatment effect. However, both traditional biological sewage ponds, such as the one disclosed in the above-mentioned patent with publication number, and biological sewage ponds with added particles as carriers cannot avoid a common problem. The foam generated by aeration covers the water surface, seriously hindering oxygen dissolution, causing poor biological activity. The existing mechanical foam removal or static foam removal devices cannot adapt to the dynamic aggregation characteristics of the foam, resulting in incomplete removal. In addition, the aeration mode used by traditional aeration devices can easily lead to uneven distribution of carrier particles in the pond, which can easily accumulate at the bottom or corners of the pond. The accumulation of carriers can significantly reduce the contact efficiency of microorganisms and pollutants, affecting the stability of the treatment. SUMMARY

[0025] The working principle of the present application is as follows: By pouring sewage and particles into the water tank 1, the height of the sewage needs to be higher than the annular partition 102 but lower than the guide plate 103, the particles can be used as microbial carriers during sewage treatment, allowing them to adhere to the outer wall. By opening the air supply device and periodically opening and closing the first electromagnetic valve installed in the inner wall of the inclined nozzle 105 and the vertical nozzle 107 through the controller, the air supply device supplies air, and the gas is periodically sprayed through the inclined nozzle 105 and the vertical nozzle 107. When the vertical nozzle 107 sprays air, the inclined nozzle 105 is closed. When the inclined nozzle 105 sprays gas, the vertical nozzle 107 is closed. When the vertical nozzle 107 sprays gas, the air is vertically aerated in the straight-flow zone to form a plug flow. Particles float and settle in the straight-flow zone. Some particles enter the spiral-flow zone through the flow gap between the annular partition 102 and the guide plate 103 and the water tank 1. When the inclined nozzle 105 sprays gas, the air is aerated obliquely to generate a tangential force, causing the sewage to form a cyclone and pushing the particles to rise along the annular path in the spiral-flow zone (by adjusting the air supply device, the air rising speed needs to be >0.3 m / s to ensure carrier suspension). The particles are driven to flow back to the straight-flow zone through the flow gap between the annular partition 102 and the guide plate 103. The straight-flow zone and the spiral-flow zone are alternately aerated (the cycle is recommended to be 10-15 min, which can be set by the controller or automatically adjusted according to the operating parameters). The time difference creates a pressure difference, driving the particles to circulate inside, avoiding the accumulation of particles inside caused by single aeration; The sewage forms a cyclone in the spiral flow area and flows in the process, the sewage drives the fan plate 207 to drive the connecting frame 206, the connecting sleeve ring 205 and the rotating shaft 203 to rotate, the rotating shaft 203 drives the fixed point ball to rotate in the process of rotating, the fixed point ball is driven to reciprocatingly ascend and descend in the inner wall of the rotating shaft 203 through the thread connection with the reciprocating thread groove, the hollow pipe 204 is driven to descend in the process of being driven to descend, and the collecting tray 225 is driven to descend into the sewage, the sewage in the process of cyclone flow drives the foam generated by aeration to float on the water surface and gather at the middle position, the collecting tray 225 is driven to descend into the sewage in the process of cyclone flow (the height of the collecting tray 225 descending into the sewage is kept within 1 cm below the water surface, so that the foam floating on the water surface cannot be collected by the collecting tray 225 when the collecting tray 225 is driven to ascend, and the depth of the collecting tray 225 is shallow, so that too much sewage is avoided), the foam is gathered at the middle position of the water surface and above the collecting tray 225 through cyclone, then the hollow pipe 204 is driven to ascend and drive the collecting tray 225 to ascend, the collecting tray 225 drives the foam floating on the water surface to ascend into the fixed cover 208 (when the collecting tray 225 is driven to ascend into the fixed cover 208 and is only air-tightly and slidably connected, the sealing property is limited to preventing the leakage of sewage / foam), the collecting tray 225 drives the square plate 213 to contact the extrusion cover 209 in the process of ascending, the extrusion cover 209 extrudes the square plate 213 to drive the air-tight slide plate 212 to slide downward on the inner wall of the water collecting tank 210, so that the inside of the water collecting tank 210 is communicated with the upper end surface of the collecting tray 225 through the water inlet and outlet 211, and the foam can flow into the water collecting tank 210 through the water inlet and outlet 211 to be collected, the hollow pipe 204 drives the collecting tray 225 and the water collecting tank 210 to ascend in the process of ascending, which synchronously drives the linkage plate 218 to air-tightly and slidably ascend on the inner wall of the fixed pipe 219, the second one-way valve in the linkage plate 218 is closed, and the air in the fixed pipe 219 flows outward through the opened first one-way valve 224; When the hollow tube 204 drives the collection tray 225 to descend again with the water collecting tank 210, the first one-way valve 224 is closed, the extrusion cover 209 stops extruding the square plate 213, the air-tight sliding plate 212 air-tightly slides to block the water inlet and outlet 211 in the water collecting tank 210, the second one-way valve is opened, the linkage plate 218 generates negative pressure when the air pressure in the fixed tube 219 decreases with the descent of the hollow tube 204, the lifting plate 215 will air-tightly slide upwards with the foam in the water collecting tank 210 and compress the second spring 217 when the air pressure in the fixed tube 219 decreases, the foam and part of the sewage above the lifting plate 215 in the water collecting tank 210 will flow along the inner wall of the hollow tube 204 and flow into the fixed tube 219 through the second one-way valve, after the air pressure in the fixed tube 219 decreases to exceed the set threshold value, the pressure monitoring element arranged in the fixed tube 219 generates an electric signal, the controller controls the voltage input to the second electromagnetic valve 222 through the generated electric signal to make the second electromagnetic valve 222 open, the foam and part of the sewage extracted above the linkage plate 218 will flow into the sewage discharge pipe 226 through the second electromagnetic valve 222 and be discharged for unified collection, which can effectively avoid that the foam covering the water surface will hinder the oxygen dissolution in the aeration process, resulting in a decrease in the dissolved oxygen concentration, and the sensitivity of aerobic microorganisms (such as nitrifying bacteria) to dissolved oxygen, and the insufficient dissolved oxygen will inhibit the metabolic activity of the aerobic microorganisms, reducing the organic matter degradation and ammonia nitrogen removal efficiency; It should be noted that during the reciprocating lifting of the linkage plate 218 in the inner wall of the fixed tube 219, the linkage plate 218 will drive the connecting head 221 and the second electromagnetic valve 222 to compress and expand the folded isolation plate 223 to prevent the foam and sewage in the fixed tube 219 from leaking, and the connecting head 221 will drive the air-tight isolation sliding piece 220 to lift together in the fixed tube 219 to maintain the air tightness of the fixed tube 219, so that the second electromagnetic valve 222 will lift together with the linkage plate 218 during the lifting and lowering of the linkage plate 218, and as long as the second electromagnetic valve 222 is opened, the sewage can be discharged into the sewage discharge pipe 226 through the second electromagnetic valve 222, compared with the traditional fixed sewage discharge pipe 226, the movable sewage discharge pipe 226 can lift together with the linkage plate 218 and keep the foam and sewage in a horizontal state, effectively avoiding the horizontal height difference between the sewage and the sewage discharge pipe 226, which causes the sewage to be unable to be effectively discharged; After the sewage is treated by the biological method, the residual particles and sludge in the water tank 1 are discharged into the cleaning slide 305 through the discharge pipe 302 by opening the electric control valve after the sewage is discharged. It is to be noted that if the sludge concentration in the water tank 1 is high after the sewage in the water tank 1 is discharged, the sludge particles are mixed together and cannot effectively flow into the cleaning slide 305 through the discharge pipe 302, and a certain amount of cleaning water needs to be discharged into the water tank 1 to reduce the sludge concentration, until the thickness of the sludge layer at the bottom of the water tank is diluted to about 1 / 3-1 / 2 of the original thickness, so as to improve the flowability. The sludge entering the cleaning slide 305 can flow to a position away from the discharge pipe 302 through the inclination angle between the rotating plate 304 and the cleaning slide 305 and the second support plate 301. Referring to Figure 9 The inclination angle between the rotating plate 304 and the cleaning slide 305 can be adjusted by twisting the screw on one side of the second support plate 301. The sliding plate 307 and the brush plate 308 are driven to reciprocate in the cleaning slide 305 by opening the first driving member. The particles and sludge between the brush plate 308 and the cleaning slide 305 will roll, and the brush plate 308 reciprocating in the rolling process will clean the aging biofilm and sludge attached to the surface of the particles. Water is supplied to the water jet head 309 through the connected water pipe, and the water jet head 309 sprays water into the cleaning slide 305 to increase the effect of cleaning the particles and sludge by the brush plate 308; The transmission column 402 is driven to rotate by opening the second driving member, and the rotating transmission belt 403 drives the fixed frame 405 to rotate. The plurality of fixed frames 405 arranged on the outer wall of the transmission belt 403 will in turn drive the material loading box 406 to rise at one end of the cleaning slide 305. The particles cleaned in the cleaning slide 305 will flow into the material loading box 406, and the water filter 407 will filter out the sludge and sewage after cleaning, so that the particles remain in the material loading box 406. As the material loading box 406 continuously rises, the electrically conductive head 410 will slide to the position of the discharge port 404 to separate from the contact with the electrically conductive coil. After the electromagnet 412 disconnects the voltage supplied by the electrically conductive coil, it loses magnetism and stops the magnetic attraction with the magnetic block 409. The weight of the inclined discharge plate 408 drives the material loading box 406 to rotate on both sides of the fixed frame 405. The particles in the material loading box 406 rotate through the inclined discharge plate 408 to the upper end surface of the guide plate 413, and then slide to the inside of the water tank 1 through the guide plate 413 for reuse. After the discharge, the electrically conductive head 410 is driven to re-contact the electrically conductive coil to supply power, so that the electromagnet 412 and the magnetic block 409 restore the magnetic attraction.
