Description

Technical Field

[0001] The present invention relates to the technical field of organic sewage treatment, and in particular to a multi-stage treatment device for organic sewage. Background Art

[0002] Traditional organic wastewater treatment technologies often rely on a single process, resulting in low efficiency, high energy consumption, and fragmented equipment. For example, conventional aeration systems rely on fixed nozzles, which can lead to uneven bubble distribution and limited gas-liquid contact efficiency. Sedimentation and filtration processes are often independent units, requiring manual intervention and poorly adapting to water quality fluctuations. Furthermore, existing equipment lacks real-time monitoring and feedback mechanisms, making it impossible to dynamically adjust operating parameters based on pollutant concentrations, which can lead to wasted resources or incomplete treatment. Therefore, we propose a multi-stage organic wastewater treatment device to address this issue. Summary of the Invention

[0018] 1. In the present invention, the multi-stage treatment device for organic sewage is described. Organic wastewater is introduced into the aeration box, and the air pump and the driving motor are started. The air pump introduces air into the connecting pipe drum through the air inlet pipe. At the same time, the driving motor drives the driving gear to rotate, and the driving gear drives the driven gear and the horizontal shaft to rotate. The horizontal shaft drives the first bevel gear and the third bevel gear to rotate through the second bevel gear. The third bevel gear drives the connecting pipe and the horizontal pipe to rotate. The horizontal shaft drives the mounting frame and the counterweight plate therein to perform circular motion. The counterweight plate is thrown outward under the action of centrifugal force and drives the spiral column to rotate through the cooperation of the spiral drum and the spiral column. The spiral column drives the connecting shaft to rotate, and the connecting shaft drives the connecting disk and the arc-shaped stirring blade to rotate. The connecting disk drives the rotating drum to rotate, so that the circular hole on the rotating drum gradually coincides with the nozzle, so that the air in the rotating drum is ejected through the circular hole and the nozzle. Bubbles are formed in the organic wastewater. During the rising process of the bubbles, the oxygen in the air gradually dissolves in the water, increasing the dissolved oxygen concentration of the water body and providing living conditions for microorganisms. The domesticated aerobic microorganisms (such as bacteria and protozoa) in the water body use dissolved oxygen as an electron acceptor and organic pollutants (such as carbohydrates, proteins, and oils) as a nutrient source for metabolism. The microorganisms secrete extracellular enzymes to hydrolyze large molecular organic matter into small molecules. The microorganisms completely mineralize small molecular organic matter (such as glucose) into carbon dioxide and water through respiration. Some organic matter is converted into microbial cell substances to support the proliferation of the bacterial colony, thereby reducing the concentration of organic matter in the wastewater. The first bevel gear drives the rotating shaft and the dispersion blades to rotate. The dispersion blades and the arc-shaped stirring blades make the air fully contact with the organic wastewater during rotation, further increasing the oxygen content in the water and improving the aeration treatment effect.

[0057] In use, the organic wastewater is introduced into the aeration tank 101, and the air pump 801 and the driving motor 701 are started. The air pump 801 introduces air into the connecting pipe 803 and the rotating drum 807 through the air inlet pipe 802. At the same time, the driving motor 701 drives the driving gear 702 to rotate, which drives the driven gear 613 and the horizontal shaft 507 to rotate. The horizontal shaft 507 drives the first bevel gear 505 and the third bevel gear 508 to rotate through the second bevel gear 506. The third bevel gear 508 drives the connecting pipe 803 and the cross pipe 804 to rotate. The horizontal shaft 507 drives the mounting frame 901 and the counterweight plate 907 inside it to move in a circular motion. The counterweight plate 907 is thrown outward under the action of centrifugal force and drives the spiral column 905 to rotate through the cooperation of the spiral cylinder 906 and the spiral column 905. The spiral column 905 drives the connecting shaft 902 to rotate, which drives the connecting disc 810 and the arc-shaped stirring blade 904 to rotate. The connecting disc 810 drives the rotating drum 807 to rotate, so that the circular holes 809 on the rotating drum 807 gradually coincide with the nozzles 805. The air in the rotating drum 807 is sprayed out through the circular holes 809 and the nozzles 805 to form bubbles in the organic wastewater. During the rising process of the bubbles, the oxygen in the air gradually dissolves in the water, which increases the dissolved oxygen concentration of the water body and provides living conditions for microorganisms. The domesticated aerobic microorganisms (such as bacteria and protozoa) in the water body use dissolved oxygen as an electron acceptor and organic pollutants (such as carbohydrates, proteins, and fats) as a nutrient source for metabolism. Extracellular enzymes secreted by microorganisms hydrolyze macromolecular organic matter into small molecules. Microorganisms completely mineralize small molecular organic matter (such as glucose) into carbon dioxide and water through respiration. Part of the organic matter is converted into microbial cell material to support the proliferation of the bacterial population, thereby reducing the concentration of organic matter in the wastewater. The rotating shaft 503 and the dispersion blade 504 are driven to rotate by the first bevel gear 505. The dispersion blade 504 and the arc-shaped stirring blade 904 make the air and the organic wastewater fully contact during rotation, further increasing the oxygen content in the water and improving the aeration treatment effect.

[0058] The driven gear 613 drives the connecting column 612 and the connecting cylinder 611 to perform circular motion. The connecting cylinder 611 drives the guide rail 609 to move up and down through the cooperation of the sliding seat 610 and the guide rail 609. The guide rail 609 drives the piston plate 607 to move up and down through the connecting rod 608. When the piston plate 607 moves downward, the water at the bottom of the aeration box 101 enters the compression box 601 through the liquid inlet pipe 604 and the second one-way valve 605, and the sensor 606 detects the organic matter content in the water. When the piston plate 607 moves upward, the water in the compression box 601 is re-circulated through the liquid outlet pipe 602 and the first one-way valve 603. The water is newly refluxed into the aeration box 101 and comes into contact with the outside air during the reflux process, further increasing the oxygen content in the water. The detection sensor 606 transmits the detection data to the controller 11. When a high organic matter content is detected, the controller 11 controls the air pump 801 and the drive motor 701 to accelerate, thereby increasing the air intake volume and the rotation speed of the driving gear 702. At the same time, the horizontal pipe 804 and the dispersion blade 504 are accelerated to rotate, thereby improving the stirring effect. The counterweight plate 907 is further thrown outward under the action of centrifugal force, so that the overlap between the nozzle 805 and the circular hole 809 is increased, thereby increasing the jet volume of the nozzle 805 and improving the aeration effect.

[0059] By starting the first water pump 202, the wastewater in the aeration tank 101 is introduced into the sedimentation tank 201. After sedimentation, the second water pump 204 is started to generate suction in the liquid extraction pipe 205. The supernatant in the sedimentation tank 201 is extracted through the extension pipe 209 and introduced into the filter cartridge 401. The filter cartridge 401 filters the impurities in the water, driving the side plate 208 and the extension pipe 209 to move up and down, thereby adjusting the height of the extension pipe 209 according to the height of the sediment.

[0060] By starting the rotating motor 405 to drive the rotating shaft 503 and the filter cartridge 401 to rotate, the sewage filtration rate is increased under the action of centrifugal force. At the same time, by loading the purification agent into the liquid inlet hopper 302 and opening the regulating valve to introduce the purification agent into the filter box 301, the rotating shaft 503 drives the stirring paddle 404 to rotate, so that the purification agent is mixed with the sewage to achieve a purification effect. For example, the purification agent uses Fenton's reagent to generate strong oxidizing hydroxyl free radicals, which completely degrade difficult-to-decompose organic matter (such as dyes and pesticides).
