Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an intelligent sensing and control shock wave mass transfer aeration system. Background Technology

[0002] Wastewater treatment employs aeration systems to forcibly oxygenate the wastewater, increasing the dissolved oxygen content and thus promoting the activity of aerobic microorganisms, accelerating the decomposition and metabolism of organic matter. The aeration process increases the dissolved oxygen concentration in the water, and simultaneously, through agitation, it thoroughly mixes organic matter and other suspended solids in the wastewater, ensuring their even distribution and increasing the contact opportunities between microorganisms and organic matter, thereby accelerating the degradation process.

[0003] In existing technologies, wastewater treatment plants consume a large amount of electricity, accounting for a significant proportion of their operational costs. The aeration portion of this electricity consumption constitutes a large portion of the total electricity consumption. Reducing the electricity consumption of the aeration portion is crucial for achieving energy conservation, carbon reduction, and green standards in wastewater treatment. However, existing aeration technologies, such as blower aeration and jet aeration, suffer from drawbacks including low oxygen transfer efficiency, high power consumption, reduced aeration volume, and difficulty in precise control.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Please see Figures 1 to 7The present invention provides the following technical solution: an intelligent sensing and control shock wave mass transfer aeration system, which includes an aeration tank 1, an aeration module 2, and a floating mechanism 3. The aeration module 2 includes a water pump 7 and a shock wave mass transfer aerator 10. Both the water pump 7 and the shock wave mass transfer aerator 10 are installed in the sewage in the aeration tank 1. The liquid inlet portion at the top of the shock wave mass transfer aerator 10 is below the water surface. A blower unit 12 is installed on the side of the aeration tank 1 via a second support plate 11. The blower unit 12 includes a blower 12, a frequency converter, and a wind speed measuring instrument. The wind speed measuring instrument is used to measure the wind speed at the inlet of the blower 12. The frequency converter is used to change the operating power of the blower 12. The blower 12 is connected to the shock wave mass transfer aerator 10 through the air supply pipe 13, the diversion pipe 14 and the air intake pipe 15 to provide the corresponding air volume to the shock wave mass transfer aerator 10. The control system collects real-time data of dissolved oxygen, pH and oxidation-reduction potential through sensors, analyzes and processes the data, and plans the control path according to the relationship between dissolved oxygen, pH, oxidation-reduction potential and air volume. It adjusts the number of water pumps 7 in operation, the operating time and the operating power of the frequency converter and the blower 12 in a timely manner. A slag discharge bin 4 is also set at the bottom of the aeration tank 1.

[0030] In this system, the intelligent sensing and control shockwave aeration system includes a sensor unit, a control system, a shockwave aeration module, and a blower unit 12. The sensor unit includes a dissolved oxygen sensor, a pH sensor, and a redox potential sensor. The shockwave mass transfer aerator 10 can be one or more units. The entire system, with the help of the intelligent sensing and control system, maintains the entire microbial biochemical reaction in an optimal state while significantly reducing power consumption and achieving carbon emission reduction. It features high oxygen transfer efficiency, more uniform mixing, less clogging, and wear resistance. The sensors continuously capture dissolved oxygen, pH, and redox potential data in the biochemical reaction zone, providing complete control over the biochemical reaction status. Based on the intelligent algorithm in the control system, the operation of the water pump 7 and the shockwave mass transfer aerator 10 is precisely controlled, achieving accurate and quantitative aeration and significantly reducing energy consumption. An anemometer continuously senses the amount of air drawn into the shockwave mass transfer aerator 10. Using the dissolved oxygen sensor readings, the control system can adjust and match the optimal air intake in real time.

[0031] In this embodiment, a first support plate 6 is provided on the inner wall of the aeration tank 1. A water pump 7 is screwed onto the surface of the first support plate 6. One end of the water pump 7 is connected to a circulation pipe 8, and the other end of the water pump 7 is connected to a conveying pipe 9. The end of the conveying pipe 9 is connected to the top of a plurality of shock wave mass transfer aerators 10. One end of the blower 12 is connected to an air supply pipe 13. A plurality of diversion pipes 14 are inserted into the end of the air supply pipe 13. A plurality of suction pipes 15 are installed on the surface of the diversion pipes 14. The end of each suction pipe 15 is embedded in the top region of the shock wave mass transfer aerator 10. The blower 12 delivers airflow into the interior of each shock wave mass transfer aerator 10. A drainage pipe 19 is installed on the side of the aeration tank 1.

[0032] Specifically, during system operation, the water pump 7 on one side of the partition 16 draws in the wastewater from the bottom, which is then transported along the conveying pipe 9 to the top of each shock wave mass transfer aerator 10. There, the wastewater mixes with the airflow delivered by the blower 12 in the air intake pipe 15 at the top of the shock wave mass transfer aerator 10, and flows downwards along the interior of the aerator 10. When bubbles enter the treatment area of ​​the shock wave mass transfer aerator 10, due to hydrodynamic effects, the size and number of bubbles continuously change, forming vortices and shock waves. During the dissolution process of the bubbles, oxygen molecules in the air are rapidly adsorbed onto the bubble surface and then quickly transferred to the water, improving aeration efficiency. The blower 12 delivers oxygen to the distribution pipe 14 through the air supply pipe 13, which then connects to the top of the shock wave mass transfer aerator 10 through multiple air intake pipes 15. This location, through negative pressure and multiple connection points with the airflow, allows oxygen to mix efficiently with the wastewater.

[0033] In this embodiment, a partition 16 is installed inside the aeration tank 1, and a lifting groove 17 is formed inside the partition 16. The floating mechanism 3 is embedded inside the lifting groove 17. The floating mechanism 3 includes a lifting plate 20 and a floating plate 21. The lifting plate 20 is installed at the bottom of the floating plate 21, and multiple notches 22 are formed on the surface of the floating plate 21. A diversion plate 23 is provided at the top of the lifting plate 20. A top-level guide hole 25 is formed at the top of the diversion plate 23, and a bottom-level guide hole 24 is formed at the bottom of the diversion plate 23. The bottom end of the lifting plate 20 is embedded inside the lifting groove 17. The top of the shock wave mass transfer aerator 10, as well as the diversion pipe 14 and the air intake pipe 15, all pass downward through the inside of the notches 22. The partition 16 is used to divide and separate the interior of the aeration tank 1. A partition 16 is installed inside the aeration tank 1, which divides the aeration tank 1 into two areas. With the help of the floating mechanism 3, the injected sewage can be circulated from the two areas respectively, thereby avoiding the stratification of sewage. This allows sewage injected into any area to receive equivalent aeration treatment through the aeration system, and the mixing efficiency of sewage and oxygen is higher.

[0034] Specifically, during the wastewater treatment process, the top floating plate floats synchronously with the rise and fall of the liquid level. This causes the bottom lifting plate 20 to move up and down along the inside of the lifting trough 17. The bottom of the floating plate 21 is separated into the top guide hole 25 and the bottom guide hole 24 by the partition 16. This allows the wastewater areas on both sides of the shock wave mass transfer aerator 10 to enter the side where the water pump 7 is located from different guide holes. With the blocking effect of the lifting plate 20 and the partition 16, it can be ensured that the wastewater sprayed from the bottom of the shock wave mass transfer aerator 10 will flow synchronously towards the top and then flow evenly into the other side of the partition 16. This avoids the problem that there is only a local circulating flow area in the entire aeration tank 1.

[0035] In this embodiment, the top of the slag discharge bin 4 is provided with multiple settling tanks 26, and each settling tank 26 is equipped with an independent settling mechanism 18. The front end of the slag discharge bin 4 is provided with a slag discharge pipe 5. The settling mechanism 18 includes a conical column 28, a pressure-bearing blade 30, and a scraper blade 32. A support shaft 33 is inserted into the bottom of the conical column 28, and a central shaft 29 is inserted into the top of the conical column 28. The pressure-bearing blade 30 is provided on the side of the central shaft 29, and a linkage rod 31 is provided in the middle of the bottom of the pressure-bearing blade 30. A scraper blade 32 is provided at the bottom of the linkage rod 31. The bottom of the shock wave mass transfer aerator 10 is provided with a nozzle 27, and the central axis of each nozzle 27 coincides with the central axis of the central shaft 29. The settling tank 26 has guide inclined plates 34 on its side, and a base 35 is integrally formed at the bottom of the settling tank 26. A collection cavity 36 is opened in the middle bottom of the base 35, and a slag discharge channel 37 is opened inside the collection cavity 36. The slag discharge pipe 5 is connected to the inside of the slag discharge channel 37. The support shaft 33 is embedded in the bottom of the collection cavity 36, and a gap is provided between the surface of the support shaft 33 and the inner wall of the collection cavity 36. The bottom of the scraper 32 is pressed against the surface of the base 35. A corresponding settling mechanism 18 is provided at the bottom of each shock wave mass transfer aerator 10. The water flow sprayed from the shock wave mass transfer aerator 10 drives the settling mechanism 18 to operate, thereby centrally treating the sediment and impurities in the aerated wastewater. During the continuous circulation process, the sediment is separated and discharged, further reducing the probability of blockage in the entire pipeline system.

[0036] Specifically, the wastewater, carrying impurities and sediments, is sprayed out towards the bottom through the nozzle 27 at the bottom of the shock wave mass transfer aerator 10. The impact force of the water flow acts on the pressure-bearing blade 30, which in turn drives the scraper blade 32 below to rotate in conjunction with the linkage rod 31 in the middle of the bottom. The sediment in the wastewater has a higher density and impacts the bottom due to inertia. Then, it is pushed towards the collection cavity 36 at the bottom of the settling tank 26 by the scraper blade 32, thereby concentrating the sediment in the collection cavity 36. The main body of the wastewater then diffuses and flows towards the top and all sides along the guide plate 34. The impurities concentrated inside the collection cavity 36 are then discharged through the slag discharge channel 37 and the slag discharge pipe 5.

[0037] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
