Description

Technical Field

[0001] The present invention relates to the technical field of sewage, and specifically relates to a marine sewage comprehensive treatment device. Background Art

[0002] A marine sewage comprehensive treatment device is a device applied to ships, aiming to efficiently treat various types of marine sewage. Its working process usually includes multiple links: First is the pretreatment link, where large solid debris in the sewage is intercepted by devices such as grilles and filters to prevent it from clogging or damaging subsequent treatment equipment; then comes the physical treatment stage, where methods such as sedimentation and flotation are used to separate suspended particles, oils and fats, etc. in the sewage; then it enters the biochemical treatment stage, relying on the metabolic function of microorganisms to decompose organic pollutants in the sewage and convert them into harmless carbon dioxide and water; finally is the advanced treatment link, where means such as filtration and disinfection are used to further remove residual impurities and pathogens in the sewage to ensure that the treated sewage meets strict international discharge standards, so that it can be safely discharged into the ocean, effectively protecting the marine ecological environment.

[0003] In the existing marine sewage comprehensive treatment device, in the biochemical treatment stage, aerobic organisms and anaerobic organisms are generally used to achieve purification, and the amounts of impurities that aerobic organisms and anaerobic organisms in the sewage can purify are different in different stages. The existing treatment method is to uniformly add the same quantity and proportion of aerobic organisms and anaerobic organisms to the two pools, which leads to an imbalance in the purification loads of the aerobic treatment pool and the anaerobic treatment pool, resulting in the situation that the organisms (aerobic organisms or anaerobic organisms) in the aerobic treatment pool and the anaerobic treatment pool have a decline in activity or even death due to an excess or shortage of "food"; at the same time, organic pollutants in the sewage cannot be efficiently decomposed in a targeted manner, making the purification efficiencies and purification effects of the two treatment stages significantly different, ultimately resulting in low overall sewage treatment efficiency, unstable treatment effects, being difficult to continuously meet international discharge standards, and affecting the compliant discharge of ship sewage and marine environmental protection. Summary of the Invention

[0004] Aiming at the above-mentioned shortcomings of the existing technology, the present invention provides a marine sewage comprehensive treatment device, which can effectively solve the problem that the aerobic treatment pool and the anaerobic treatment pool in the existing technology uniformly add the same quantity and proportion of aerobic organisms and anaerobic organisms, resulting in an imbalance in the purification loads of the two pools due to the different amounts of impurities purified by aerobic organisms and anaerobic organisms in the sewage at different stages.

[0006] Preferably, a controller is installed on the side of the base; The purification component includes a sewage tank fixedly connected to the upper end face of the base. A partition plate is fixedly connected to the central position inside the sewage tank. The partition plate divides the inside of the sewage tank into an aerobic area and an anoxic area.

Detectors are fixedly connected inside both the aerobic area and the anoxic area, and the detectors are electrically connected to the controller. A water inlet pipe is fixedly connected to the side of the aerobic area, and the other end of the water inlet pipe is communicated with the previous process. A transfer pipe is fixedly connected to the bottom of the aerobic area. A water outlet pipe is fixedly connected to the bottom of the anoxic area, and the other end of the water outlet pipe is communicated with the next process; Porous bottom plates are fixedly connected to the lower positions inside both the aerobic area and the anoxic area. One-way disks are rotatably connected inside the holes of the porous bottom plates.

[0007] Preferably, the aerobic component includes a first cover plate fixedly connected to the upper end face of the aerobic area. An oxygenation blower is fixedly connected to the upper end face of the first cover plate, and the oxygenation blower is electrically connected to the controller.

A liquid discharge pipe rack is fixedly connected to the bottom of the second cover plate, and the liquid discharge pipe rack is communicated with the output end of the communication valve.

[0008] Preferably, the air extraction component includes a liquid deaerator fixedly connected to the side of the base.

The output end of the liquid deaerator is fixedly communicated with a communication pipe, and the other end of the communication pipe is communicated with the input end of the communication valve.

[0009] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art: 1. Through the purification component, aerobic component, anoxic component and air extraction component in the sewage purification mechanism, the purification of sewage by aerobic organisms and anoxic organisms can be achieved. Among them, the purification component realizes the storage of sewage and constitutes two environments of aerobic and anoxic to achieve the purification of sewage by aerobic organisms and anoxic organisms. When the aerobic component realizes the purification of sewage by aerobic organisms, it continuously supplements the oxygen required for aerobic organisms to purify sewage. When the air extraction component realizes the transfer of sewage from the aerobic environment to the anoxic environment, it extracts the air existing in the sewage and cooperates with the anoxic component to ensure the anoxic environment required for anoxic organisms to purify sewage when organisms purify sewage, thereby efficiently removing organic pollutants in the sewage, utilizing the different metabolic characteristics of aerobic organisms and anoxic organisms, improving the comprehensiveness and effect of sewage purification, reducing energy consumption, and improving the treatment efficiency.

[0010] 2. Through the gas delivery component and liquid delivery component in the biological delivery mechanism, the number control of the delivery box components put into the sewage and the timely replenishment of new organisms (aerobic organisms or anoxic organisms) to the used delivery box components can be realized. Among them, the gas delivery component realizes the number of delivery box components put into the sewage through the number of connected delivery box components, and then determines the amount of aerobic organisms or anoxic organisms put into the sewage for purifying sewage. The liquid delivery component realizes the delivery of a liquid containing new aerobic organisms or anoxic organisms to the delivery box components after the delivery box components put into the sewage are used up, to supplement the loss of organisms when the delivery box components are put into the sewage. After the delivery box components are used, a liquid containing fresh aerobic organisms or anoxic organisms is timely replenished to quickly restore the number of organisms and ensure the continuous and efficient operation of the biological purification process.

[0011] 3. Through the delivery box components and biological racks in the biological delivery mechanism, the limitation of aerobic organisms or anoxic organisms can be realized, and then the number of aerobic organisms or anoxic organisms can be controlled. Among them, the biological rack is used for attaching aerobic organisms or anoxic organisms, and the number of aerobic organisms or anoxic organisms attached to the biological rack is limited by the volume of the biological rack. The delivery box components are opened when they sink into the sewage, so that the sewage contacts the biological rack located inside it, to promote the full contact of the aerobic organisms and anoxic organisms attached to the biological rack with the sewage. The delivery box components automatically open when they sink into the sewage, so that the internal biological rack is fully contacted with the sewage, maximizing the reaction area between microorganisms and pollutants, improving the purification efficiency, and at the same time preventing the loss or damage of organisms during the delivery process.

Detailed implementation mode

[0015] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0016] The present invention will be further described below with reference to the embodiments.

[0017] Embodiment: Refer to Figures 1 to 14 , a marine sewage comprehensive treatment device, comprising: Base 1; Sewage purification mechanism 2, the sewage purification mechanism 2 includes a purification component 21 arranged on the upper end surface of the base 1, an aerobic component 22 and an anoxic component 24 are arranged in parallel on the upper end surface of the purification component 21, and an air extraction component 26 communicating with the aerobic component 22 and the anoxic component 24 is arranged on the side surface of the base 1; Biological delivery mechanism 4, there are two pairs of biological delivery mechanisms 4, and the two pairs of biological delivery mechanisms 4 are respectively arranged on the upper end faces of the aerobic component 22 and the anoxic component 24. The biological delivery mechanism 4 includes a protective box 41 arranged on the upper end faces of the aerobic component 22 and the anoxic component 24. The upper end face of the protective box 41 is successively provided with a gas delivery component 42 and a liquid delivery component 43 from bottom to top. A plurality of delivery box components 44 are arranged inside the protective box 41. A biological rack 45 is arranged inside each delivery box component 44. Biological breeders 46 and air compressors 47 are fixedly connected to the two sides of the base 1 corresponding to the aerobic component 22 and the anoxic component 24 respectively.

[0018] The purification component 21 in the sewage purification mechanism 2 is used to respectively carry out aerobic biological and anoxic biological purification of sewage. When the aerobic component 22 is used to purify sewage by aerobic organisms, air is continuously delivered into the sewage to increase the oxygen content in the sewage, thereby enhancing the purification effect of aerobic organisms on sewage. When the anoxic component 24 is used to purify sewage by anoxic organisms, the oxygen content in the sewage is reduced, thereby enhancing the purification effect of organisms on sewage. And the air extraction component 26 is used to extract the air in the sewage when the sewage is transferred from the aerobic biological purification environment to the anoxic biological purification environment, so as to ensure that the oxygen content of the sewage entering the anoxic biological purification environment is low.

[0019] Refer to Figures 1 to 3 、 Figure 6 A controller is installed on the side of the base 1; The purification component 21 includes a sewage tank 211 fixedly connected to the upper end face of the base 1. A partition plate 212 is fixedly connected to the central position inside the sewage tank 211. The partition plate 212 divides the inside of the sewage tank 211 into an aerobic area and an anoxic area. Exhaust holes 213 are linearly arranged on both opposite sides of the aerobic area. A gas plate 214 is hingedly connected to the inside of each exhaust hole 213. Detectors 215 are fixedly connected to the inside of the aerobic area and the anoxic area, and the detectors 215 are electrically connected to the controller. A water inlet pipe 216 is fixedly connected to the side of the aerobic area, and the other end of the water inlet pipe 216 is communicated with the previous process. A transfer pipe 217 is fixedly connected to the bottom of the aerobic area. A water outlet pipe 218 is fixedly connected to the bottom of the anoxic area, and the other end of the water outlet pipe 218 is communicated with the next process; Porous bottom plates 27 are fixedly connected to the lower positions inside the aerobic area and the anoxic area. One-way disks 28 are rotatably connected to the holes of the porous bottom plates 27.

[0020] The partition plate 212 is used to divide the sewage tank 211 into an aerobic area and an anoxic area. The biological breeder 46 located in the aerobic area is used to cultivate and breed aerobic organisms, and the biological breeder 46 located in the anoxic area is used to cultivate anoxic aerobic organisms. And the exhaust holes 213 in the aerobic area are used to deliver air from the aerobic component 22 into the sewage in the aerobic area to ensure the stability of the air pressure in the aerobic area.

[0021] Reference Figures 1 to 2 、 Figure 4 The aerobic component 22 includes a first cover plate 221 fixedly connected to the upper end surface of the aerobic zone. An aeration fan 222 is fixedly connected to the upper end surface of the first cover plate 221, and the aeration fan 222 is electrically connected to the controller. A exhaust pipe rack 23 is fixedly connected to the bottom of the first cover plate 221, and the output end of the aeration fan 222 is communicated with the exhaust pipe rack 23; The anoxic component 24 includes a second cover plate 241 fixedly connected to the upper end surface of the anoxic zone. At least two one-way exhaust valves 242 and a communication valve 243 are fixedly communicated with the upper end surface of the second cover plate 241. A liquid discharge pipe rack 25 is fixedly connected to the bottom of the second cover plate 241, and the liquid discharge pipe rack 25 is communicated with the output end of the communication valve 243.

[0022] The air extraction component 26 includes a liquid degasser 261 fixedly connected to the side surface of the base 1. The other end of the transfer liquid pipe 217 is communicated with the input end of the liquid degasser 261. The output end of the liquid degasser 261 is fixedly communicated with a communication pipe 262, and the other end of the communication pipe 262 is communicated with the input end of the communication valve 243.

[0023] The first cover plate 221 in the aerobic component 22 is used to seal the aerobic zone, and the aeration fan 222 is communicated with the exhaust pipe rack 23, so that the exhaust pipe rack 23 discharges air into the sewage, increasing the oxygen content in the sewage in the aerobic zone. The second cover plate 241 in the anoxic component 24 seals the anoxic zone, and the input end of the air extraction component 26 is communicated with the transfer liquid pipe 217, so that the sewage is sucked out of the aerobic zone through the transfer liquid pipe 217.

[0024] Reference Figures 1 to 3 、 Figure 7 It further includes a liquid stirring mechanism 3. There are two pairs of the liquid stirring mechanisms 3, and each pair of the liquid stirring mechanisms 3 corresponds to the aerobic zone and the anoxic zone respectively. The liquid stirring mechanism 3 includes a liquid frame 31 fixedly communicated with the aerobic zone and the anoxic zone. A plurality of hydraulic rods 32 are fixedly connected to the inner wall of the liquid frame 31 in a linear array, and the hydraulic rods 32 are electrically connected to the controller. The telescopic ends of the hydraulic rods 32 are commonly fixedly connected to a slide plate 33, and the slide plate 33 is hermetically slidably connected to the inner wall. On the other side of the slide plate 33, multiple groups of concave-convex plates 34 and a plurality of V-shaped plates 35 are alternately fixedly connected. Each group of the concave-convex plates 34 has at least two, and they are linearly arrayed in the width direction of the slide plate 33.

[0025] The slow reciprocating movement of the hydraulic rods 32 in the liquid stirring mechanism 3 is used to push the slide plate 33 to reciprocate in the liquid frame 31. As the slide plate 33 reciprocates, the concave-convex plates 34 and the V-shaped plates 35 cannot move, and then the sewage in the aerobic zone and the anoxic zone is pushed through the concave-convex plates 34 and the V-shaped plates 35 to form small-amplitude waves.

[0026] Reference Figure 1 and Figures 8 to 9 At an upper position inside the protection box 41, a limiting plate 411 is fixedly connected, and a perforated plate 412 is fixedly connected to the bottom of the protection box 41; The gas delivery assembly 42 includes a ventilation pipe 421 fixedly connected to the upper end face of the protection box 41. The ventilation pipe 421 has one input end and multiple output ends. The input end of the ventilation pipe 421 is fixedly communicated with an air delivery pipe 422. The output ends of the ventilation pipe 421 are fixedly communicated with gas solenoid valves 423 through pipes, and the gas solenoid valves 423 are electrically connected to the controller. The output ends of the gas solenoid valves 423 are fixedly communicated with telescopic pipes 424. The other ends of the telescopic pipes 424 penetrate through the protection box 41 and the limiting plate 411 and extend into the interior of the protection box 41.

[0027] By connecting with the air compressor 47 corresponding to the ventilation pipe 421 in the gas delivery assembly 42, the compressed air in the air compressor 47 is transmitted to the gas solenoid valves 423. The number of opened gas solenoid valves 423 determines how many dosing box assemblies 44 descend into the sewage. When the air compressor 47 sucks air, the dosing box assemblies 44 start to rise.

[0028] Reference Figure 1 and Figures 8 to 9 The liquid delivery assembly 43 includes a liquid delivery pipe 431 fixedly connected to the upper end face of the ventilation pipe 421. The liquid delivery pipe 431 has one input end and multiple output ends. The input end of the liquid delivery pipe 431 is fixedly communicated with an infusion pipe 432. The output ends of the liquid delivery pipe 431 are fixedly communicated with liquid solenoid valves 433 through pipes, and the liquid solenoid valves 433 are electrically connected to the controller. The liquid solenoid valves 433 have at least two output ends and one input end. The output ends of the liquid solenoid valves 433 are fixedly communicated with liquid supplement pipes 434. The other ends of the liquid supplement pipes 434 penetrate through the protection box 41 and the limiting plate 411 and extend into the interior of the protection box 41 and are fixedly communicated with convex magnetic heads 435.

[0029] By connecting the infusion pipe 432 in the liquid delivery assembly 43 with the corresponding biological propagator 46, the liquid containing organisms in the biological propagator 46 is transported into the dosing box assembly 44 that has descended into the sewage for purification, thereby supplementing the organisms lost by the biological racks 45 in the dosing box assembly 44.

[0030] Reference Figure 8 and Figures 9 to 12, the number and position of the holes in the dosing box assembly 44 correspond one by one to those of the porous plate 412. The dosing box assembly 44 includes a dosing box 441 slidably connected inside the porous plate 412. The upper end face of the dosing box 441 is fixedly communicated with a concave magnetic head 442 corresponding to the convex magnetic head 435, and the convex magnetic head 435 and the concave magnetic head 442 are magnetically adsorbed. A drain pipe 4421 corresponding to the concave magnetic head 442 is fixedly connected to the inner top of the dosing box 441, and the drain pipe 4421 penetrates the inner top of the dosing box 441 and is communicated with the concave magnetic head 442. The other end of the telescopic pipe 424 is fixedly communicated with the upper end face of the dosing box 441. A pair of air-permeable blocks 443 are fixedly communicated with the upper end face of the dosing box 441.

[0031] By using the magnetic attraction between the concave magnetic head 442 in the dosing box assembly 44 and the convex magnetic head 435 of the liquid supply pipe 434, the connection between the liquid supply pipe 434 and the drain pipe 4421 can be realized. Furthermore, the liquid passing through the opened liquid solenoid valve 433 can be injected into the dosing box 441 through the drain pipe 4421, so as to replenish the organisms in the dosing box 441 for the biological reproducer 46. The lifting height of the dosing box 441 limited by the limiting plate 411 ensures the position correspondence between the convex magnetic head 435 and the concave magnetic head 442.

[0032] Refer to Figures 12 to 13 , opening and closing structures 444 are arranged around the dosing box 441. The opening and closing structures 444 include a multi-port plate 4441 fixedly connected to the side of the dosing box 441. A telescopic plate 4442 is slidably connected in each port of the multi-port plate 4441. The telescopic ends of adjacent two telescopic plates 4442 facing the inside of the dosing box 441 are jointly fixedly connected with an interlinking rod 4443. A linkage rod 4445 is jointly fixedly connected to the central positions of the interlinking rods 4443. A spring 4444 is fixedly connected to one side of the linkage rod 4445, and the other end of the spring 4444 is fixedly connected to the inner top of the dosing box 441. The other side of the linkage rod 4445 penetrates the inner bottom of the dosing box 441 and is fixedly connected with a counterweight seat 4446.

[0033] By using the multi-port plate 4441 in the opening and closing structure 444 to cooperate with the telescopic plate 4442, the sealing of the dosing box 441 can be realized. When the dosing box 441 touches the bottom of the aerobic zone or the anaerobic zone, the counterweight seat 4446 enables the self-weight of the dosing box 441 and the weight of the biological rack 45 to make the linkage rod 4445 rise, thereby driving the interlinking rod 4443 to open the telescopic plate 4442, so that the sewage in the corresponding area enters the dosing box 441 from the ports of the multi-port plate 4441 and contacts the organisms attached to the biological rack 45, and cooperates with the liquid stirring mechanism 3 to realize the purification of the sewage of the organisms attached to the biological rack 45.

[0034] Refer to Figures 10 to 11A sliding frame 445 is slidably connected to the lower side of the delivery box 441, and a bottom plate 446 is fixedly connected to the bottom of the side of the delivery box 441. Air bags 447 and force storage springs 448 are fixedly connected to the opposite surfaces of the sliding frame 445 and the bottom plate 446 respectively. A pair of pressure relief holes that are interconnected are provided at the bottom of the delivery box 441 and the bottom plate 446, and a pressure door 449 is clamped inside the pressure relief hole. The biological rack 45 is fixedly connected to the inner bottom of the delivery box 441.

[0035] The airbag 447 and the force storage spring 448 are used to achieve buffering when the holes of the porous plate 412 overlap with the sliding frame 445 when the delivery box 441 returns to the protection box 41, and the pressure door 449 is used to discharge the sewage that enters the delivery box 441 during the recovery process.

[0036] Reference Figure 12 , Figure 14 The biological propagator 46 and the air compressor 47 are both electrically connected to the controller, and the base 1 and the two sides corresponding to the aerobic component 22 and the anaerobic component 24 are fixedly connected with a dividing valve 461 and an air dividing valve 471, and the dividing valve 461 and the air dividing valve 471 each have an input end and two output ends, the output end of the biological propagator 46 is connected to the input end of the dividing valve 461 through a pipeline, the other end of each pair of infusion tubes 432 is connected to the output end of the dividing valve 461, and the other end of each pair of air supply tubes 422 is connected to the output end of the air dividing valve 471.

[0037] The biological propagator 46 located in the aerobic zone is used to cultivate and reproduce aerobic organisms, and the biological delivery mechanism 4 of the aerobic component 22 is transmitted through the distribution valve 461, while the biological propagator 46 located in the anoxic zone is used to cultivate and reproduce anoxic organisms.

[0038] The operating principle of this embodiment is as follows: The first step: First, it is connected to the previous process through the water inlet pipe 216 (the previous process refers to the physical treatment stage). The sewage tank 211 is divided into an aerobic zone and an anoxic zone by the partition board 212. Therefore, the water inlet pipe 216 will first transport the sewage to the aerobic zone of the sewage tank 211. The sewage transported to the aerobic zone will be discharged into the aerobic zone through the porous bottom plate 27 located in the aerobic zone. However, a one-way disk 28 is rotatably connected inside the holes of the porous bottom plate 27. The one-way disk 28 rotates with the inflow of sewage inside the holes of the porous bottom plate 27, adjusting the water flow direction to evenly diffuse the sewage. At the same time, its one-way conduction characteristic prevents the sewage in the aerobic zone from flowing back into the water inlet pipe 216, and also reduces the formation of turbulent flow in the aerobic zone, ensuring the stability of the living environment of microorganisms in the aerobic zone and creating favorable conditions for the attachment and growth of microorganisms and the decomposition of organic pollutants. When the water level detector located in the aerobic zone detects the presence of sewage (the water level detector is a prior art, so it is not shown in the figure), it will feedback information to the controller, thereby starting the aeration fan 222 of the aerobic component 22 (the aeration fan 222). With the start of the aeration fan 222, the aeration fan 222 inhales the outside air, performs aeration treatment, and then transports it to the exhaust pipe rack 23. The exhaust pipe rack 23 can discharge the air into the sewage in the aerobic zone to increase the oxygen content in the sewage.

[0039] Among them, since the first cover plate 221 covers the upper end surface of the aerobic zone, it plays a good sealing role, preventing oxygen leakage and the entry of external impurities. As the exhaust pipe rack 23 continuously discharges air into the aerobic zone, it will cause the air pressure in the aerobic zone to increase. Therefore, exhaust holes 213 are opened on both sides of the aerobic zone, and a gas plate 214 is hinged inside each exhaust hole 213. When the air pressure in the aerobic zone increases, the gas plate 214 will open under the action of the air pressure, allowing the air to be discharged smoothly, ensuring the stability of the air pressure in the aerobic zone. When the external air pressure changes or the air pressure in the aerobic zone decreases, the gas plate 214 will automatically close, effectively preventing the reverse entry of external air into the aerobic zone, thereby maintaining a stable aerobic environment in the aerobic zone; And the sufficient oxygen supply provides the necessary living conditions for the dosing box assembly 44 with aerobic organisms put in by the biological dosing mechanism 4 corresponding to the subsequent aerobic component 22. Aerobic organisms can decompose organic pollutants in sewage more efficiently in an aerobic environment. They use their own metabolic mechanisms to convert organic pollutants into harmless substances such as carbon dioxide and water, realizing the aerobic purification of sewage. The detector 215 located in the aerobic zone can detect multiple key indicators in the sewage, including the content of organic pollutants, the concentration of dissolved oxygen, the activity of microorganisms, etc. The detector 215 continuously transmits these data to the controller, and then the controller can determine the number of dosing box assemblies 44 with aerobic organisms to be put in according to the data.

[0040] Step 2: Among them, when the sewage enters the aerobic zone and the aerobic component 22 starts the oxygenation treatment of the sewage, the controller then starts the air compressor 47 in the aerobic zone to rotate forward to suck in outside air. With the start of the air compressor 47, after the air compressor 47 compresses the outside air, it is transported to the ventilation pipe 421 through the air delivery pipe 422. The ventilation pipe 421 has multiple output ends, and each output end is connected to a gas solenoid valve 423 through a pipe. The gas solenoid valve 423 is electrically connected to the controller, and its opening and closing states are controlled by the controller; When the gas solenoid valve 423 is opened, the compressed air sequentially passes through the ventilation pipe 421, the gas solenoid valve 423, and the telescopic pipe 424, thereby causing the telescopic pipe 424 to start extending. As the telescopic pipe 424 extends, it will drive the corresponding dosing tank assembly 44 to disengage from the protective box 41 and start descending towards the corresponding aerobic zone. Therefore, by controlling the number of gas solenoid valves 423 opened or closed by the controller, the number of connected dosing tank assemblies 44 can be accurately controlled. The controller controls the number of gas solenoid valves 423 based on the content of organic pollutants that need to be aerobically purified in the aerobic pond feedback by the detector 215. For example, when the content of organic pollutants in the sewage is relatively high and the detector 215 detects that the pollution degree of the sewage exceeds the set threshold, the controller will instruct more gas solenoid valves 423 to open, causing more dosing tank assemblies 44 to sink into the sewage to increase the number of organisms participating in the purification and improve the purification effect.

[0041] Among them, when each telescopic pipe 424 causes the dosing tank assembly 44 to descend towards the aerobic zone, when the dosing tank assembly 44 touches the porous bottom plate 27 of the aerobic zone, it means that the telescopic pipe 424 can no longer extend. As a result, the air compressor 47 is affected. At this time, the compressed air continuously delivered by the air compressor 47 cannot push the dosing tank assembly 44 to descend further, resulting in the air in the telescopic pipe 424 and the connected air path being unable to be discharged smoothly, and the internal pressure of the air compressor 47 increases accordingly. The pressure sensing device provided in the air compressor 47 monitors that the pressure exceeds the normal working range and transmits a signal to the controller. The controller issues an instruction according to the preset program to turn off the air compressor 47 to stop its operation, and at the same time closes the corresponding opened gas solenoid valve 423 to cut off the air path, so that the gas originally in the telescopic pipe 424 is stored in the telescopic pipe 424 to maintain the extended state of the telescopic pipe 424 and prevent the telescopic pipe 424 from contracting, which may cause the dosing tank assembly 44 to rise.

[0042] Among them, when the dosing tank assembly 44 contacts the porous bottom plate 27 in the aerobic zone, due to the self-weight of the dosing tank 441, the weight of the biological rack 45, and the thrust of the telescopic pipe 424 in the extended state, a downward pressure will be generated on the counterweight seat 4446 of the opening and closing structure 444. The counterweight seat 4446 is connected to the linkage rod 4445. Under the action of the pressure, the linkage rod 4445 moves upward. The upward movement of the linkage rod 4445 will pull the interlinkage rod 4443, and the interlinkage rod 4443 is connected to multiple telescopic plates 4442, thereby opening the telescopic plates 4442. At this time, the sewage in the aerobic zone will pour into the dosing tank 441 from the opening of the multi-port plate 4441 and come into full contact with the organisms attached to the biological rack 45 (the aerobic organisms maintained by the biological rack 45 before the dosing tank assembly 44 detaches, and the specific replenishment situation will be described below). Under the action of the water flow disturbance generated by the liquid stirring mechanism 3, the mass transfer between the sewage and the organisms is more sufficient, further promoting the decomposition of organic pollutants in the sewage by the organisms; When the detector 215 detects that the aerobic organisms in the aerobic zone have completed the purification of sewage organic matter, it will feedback information to the controller, so that the controller controls the air compressor 47 to reverse to suck the air in the ventilation pipe 421, so that the ventilation pipe 421 is in a negative pressure state. At the same time, the controller will open the gas solenoid valve 423 corresponding to the descending dosing tank assembly 44 to reconnect the gas path. Then, the gas originally stored in the telescopic pipe 424 is sucked and is in a negative pressure state, which causes the telescopic pipe 424 to contract. As the telescopic pipe 424 contracts, it acts on the dosing tank assembly 44, and the dosing tank assembly 44 starts to rise and detach from the porous bottom plate 27 in the aerobic zone under the action of its pulling force. During this process, the air compressor 47 continuously supplies stable air, and the gas solenoid valve 423 remains open until the dosing tank assembly 44 reaches the position of the limit plate 411, the telescopic pipe 424 cannot be telescoped, the air compressor 47 continuously sucks air to increase the internal negative pressure, and the pressure sensing device transmits the signal to the controller. The controller issues an order to turn off the air compressor 47 and the corresponding gas solenoid valve 423, cut off the gas path, stabilize the gas state in the telescopic pipe 424, ensure the stability of the equipment, and facilitate subsequent operations.

[0043] Among them, when the dosing tank assembly 44 completes the purification task and rises, the biological reproducer 46 in the aerobic zone is started accordingly. The liquid delivery assembly 43 is connected to the biological reproducer 46 through the infusion pipe 432. The biological reproducer 46 simulates a suitable environment inside and continuously cultivates aerobic organisms for purifying sewage. At the same time, the controller also opens the liquid solenoid valve 433 corresponding to the amount of sewage input by the dosing tank assembly 44. When the dosing tank assembly 44 rises to the position of the limit plate 411, the convex magnetic head 435 of the liquid replenishment pipe 434 will be magnetically adsorbed to the concave magnetic head 442 on the upper end surface of the dosing tank 441, so that the liquid replenishment pipe 434 is connected to the drain pipe 4421; At this time, the liquid solenoid valve 433 is opened, and the liquid containing new organisms in the biological incubator 46 will, under pressure, pass through the liquid supply pipe 434, the convex magnetic head 435, and the concave magnetic head 442, and be injected into the dosing tank 441 through the drain pipe 4421. This process can timely supplement the biomass reduced due to metabolism and loss during the sewage purification process by the biological rack 45, ensuring that there is always a sufficient quantity and activity of organisms on the biological rack 45 for the next use.

[0044] Among them, in the aerobic zone, after the sewage is preliminarily purified by aerobic organisms, some of the organic pollutants in it have been decomposed and transformed. When the detector 215 located in the aerobic zone detects that the purification degree of the sewage reaches the standard and meets the condition for transfer to the anoxic zone, the controller will start the liquid degasser 261, so that the sewage is sucked out from the bottom of the aerobic zone through the transfer pipe 217 and enters the liquid degasser 261, and the liquid degasser 261 realizes the extraction of air in the sewage, effectively reducing the oxygen content in the sewage. The degassed sewage is transported to the anoxic zone through the connecting pipe 262. When the water level detector in the aerobic zone cannot detect the sewage, the corresponding aerobic components 22, the air extraction component 26, the gas transmission component 42, the liquid transmission component 43, and the dosing tank component 44 in the aerobic zone will be closed through the controller.

[0045] Step 3: When the connecting pipe 262 transports the sewage to the anoxic zone, due to the connecting pipe 262 and the connecting valve 243, and the connecting valve 243 is connected to the drain pipe rack 25, the drain pipe rack 25 can discharge the sewage into the anoxic zone. After the water level detector in the anoxic zone detects the presence of sewage, it will repeat the steps of the gas transmission component 42, the liquid transmission component 43, and the dosing tank component 44 in Step 2. However, at this time, the liquid transmission component 43 is connected to the biological incubator 46 to cultivate anoxic organisms for purifying sewage. Thus, in the anoxic environment, the anoxic organisms use their unique metabolic methods to further decompose the residual organic pollutants in the sewage and convert them into harmless substances, achieving the deep purification of the sewage. Among them, when the sewage has undergone purification treatment in the anoxic zone and the detector 215 detects that the organic pollutants in the sewage have reached the discharge standard, at this time, the next process will suck out the sewage from the bottom of the anoxic zone through the outlet pipe 218, thus realizing the purification of impurities in the sewage in the biochemical treatment stage.

[0046] It should be noted that during the operation of the dosing tank component 44 of the biological dosing mechanism 4 in the anoxic zone, the air permeable block 443 balances the air pressure inside and outside the dosing tank when the dosing tank component 44 descends and rises, ensuring the stability of the biological living environment; when the dosing tank component 44 descends, the airbag 447 is compressed by the water pressure to store elastic potential energy and provides buffer protection.

[0047] Step 4: It should be supplemented that when purifying sewage by using the biological (aerobic or anoxic organisms) attached to the biological rack 45 in the dosing box assembly 44 placed in the aerobic zone and the anoxic zone, the controller will correspondingly activate the liquid stirring mechanism 3 corresponding to the aerobic zone and the anoxic zone. The liquid stirring mechanism 3 mainly consists of a liquid frame 31 fixedly connected to the corresponding area and a plurality of hydraulic rods 32 installed on the inner wall of the liquid frame 31 in a linear array. The hydraulic rods 32 receive the instructions issued by the controller and will perform slow reciprocating telescopic movements. As the hydraulic rods 32 expand and contract, the sliding plate 33 reciprocates in the liquid frame 31. When the sliding plate 33 reciprocates, the concave-convex plate 34 and the V-shaped plate 35 also move accordingly. They continuously stir in the sewage, causing the sewage to form small but continuous and stable waves. The generation of such tiny waves increases the contact area and contact frequency between the sewage and the aerobic organisms attached to the biological rack 45. On the one hand, more sewage can directly contact the aerobic organisms, enabling the aerobic organisms to fully absorb the organic pollutants in the sewage; on the other hand, the frequent contact promotes mass exchange and speeds up the decomposition rate of the organic pollutants, thus significantly improving the purification efficiency.
