Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an integrated continuous flow vertical stratified A0A-AGS reactor device. Background Technology

[0002] Traditional wastewater treatment processes such as A² / O and oxidation ditches generally suffer from problems such as large footprint, high energy consumption, and easy sludge expansion. In recent years, aerobic granular sludge technology has received widespread attention due to its excellent settling performance, high biomass concentration, and simultaneous nitrogen and phosphorus removal capabilities. However, existing AGS reactors mostly adopt a sequencing batch operation mode, which has shortcomings such as complex operation and difficulty in achieving continuous flow treatment. When existing technologies attempt to combine AOA (Anaerobic-Aerobic) processes with AGS (Aerobic-Suspended System), they either use physical partitions to forcibly separate anaerobic, aerobic, and anoxic zones. This rigid separation disrupts the integrity of the hydraulic flow field inside the reactor, which is detrimental to the formation and maintenance of granular sludge. Alternatively, although a partitionless design is used, the dissolved oxygen gradient in the vertical direction is not precisely controlled, resulting in the inability of the microbial community to form a stable stratified structure. Anaerobic, aerobic, and anoxic bacteria interfere with each other, weakening the short-cut nitrification and denitrification advantages of the AOA process. Summary of the Invention

[0003] The purpose of this invention is to address the problem that although the existing technology adopts a partitionless design, it fails to accurately control the dissolved oxygen gradient in the vertical direction, resulting in the inability of the microbial population to form a stable stratified structure. This leads to mutual interference between anaerobic, aerobic, and anoxic bacteria, weakening the short-cut nitrification and denitrification advantages of the AOA process. Therefore, an integrated continuous flow vertical stratified AOA-AGS reactor device is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An integrated continuous flow vertical stratified A0A-AGS reactor device includes a steel reactor. The interior of the steel reactor is arranged from bottom to top as an anaerobic zone, an aerobic zone, and an anoxic zone. A notch is formed at the top of the outer wall of the steel reactor, and a guide slot is formed inside the notch. The guide slot has an arc-shaped structure, and an arc-shaped sealing plate is inserted into the guide slot. The sealing plate moves up and down along the guide slot. A recovery box is fixedly connected to the top of the sealing plate. The recovery box has an arc-shaped box structure with an open top. A triangular effluent weir is fixedly connected to the side of the recovery box near the inner wall of the steel reactor. The triangular effluent weir moves up and down with the sealing plate and controls the flow of water from the steel reactor into the recovery box.

[0005] Preferably, an air separator is fixedly connected to the top of the outer wall of the steel reactor. An air inlet is provided on the outer side of the air separator in a linear array. An inclined surface is provided on the right end of the air separator, and an air outlet is provided on the inclined surface.

[0006] Preferably, a sludge return unit is fixedly connected to the inner side of the steel reactor. The sludge return unit includes a uniform sludge discharge structure. A DO sensor and an ORP sensor are fixedly connected to the inner wall of the steel reactor, with the ORP sensor located above the DO sensor.

[0007] Preferably, a water distribution support is fixedly connected to the inner side of the steel reactor. The water distribution support has an annular structure, and water distribution pipes are fixedly connected in an annular array on the inner wall of the water distribution support. The water distribution pipes are inclined and communicate with the water distribution support.

[0008] Preferably, a water inlet pipe is fixedly connected to the outer wall of the water distribution support, and a steel reactor extends outward from the water inlet end of the water inlet pipe. The water inlet pipe is connected to the water distribution support, and a water inlet pump is fixedly connected to the outer wall of the water inlet pipe. The water inlet pump is used to control the flow rate and volume of the water entering the water distribution support.

[0009] Preferably, an aeration support is fixedly connected to the inner wall of the steel reactor. The aeration support has an annular structure and is located above the water distribution support. An air inlet pipe extending out of the steel reactor is fixedly connected to the outer side of the aeration support. An air inlet pump is fixedly connected to the outer wall of the air inlet pipe.

[0010] Preferably, a porous aeration disc is fixedly connected to the inner wall of the aeration support. Aeration holes are arranged in a ring array on the top surface of the porous aeration disc. The aeration holes and the porous aeration disc are connected to the aeration support and are used to aerate the interior of the steel reactor to form an aerobic zone.

[0011] Preferably, a support base plate is fixedly connected to the outer wall of the steel reactor. There are two support base plates, which are symmetrically fixed to the outer wall of the steel reactor. A servo push rod is fixedly connected to the top surface of each of the two support base plates.

[0012] Preferably, a support top plate is fixedly connected to the top of the servo push rod, the support top plate is fixedly installed on the outer wall of the recycling box, and a flocculent sludge sorting plate is fixedly connected to the inner wall of the recycling box, with sorting holes opened in the internal annular array of the flocculent sludge sorting plate.

[0013] Preferably, a connecting support plate is fixedly connected to the inner wall of the recycling bin, a connecting guide rod is fixedly connected to the bottom end of the connecting support plate, and a water immersion sensor is fixedly connected to the bottom end of the connecting guide rod. The water immersion sensor is used to detect the water level inside the steel reactor and is electrically connected to a servo push rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, by setting components such as a sealing plate, a guide slot, a recovery box, a triangular outlet weir, a servo push rod, and an immersion sensor, the immersion sensor detects the water level inside the steel reactor and is electrically connected to the servo push rod. This allows the servo push rod to drive the recovery box to move the sealing plate up and down along the guide slot according to the water level change, thereby causing the triangular outlet weir to change the overflow liquid level. This device can solve the problem of the difficulty in dynamically adjusting the effluent water level under different operating conditions, and avoid sludge loss or effluent water quality deterioration due to water level fluctuations.

[0015] 2. In this invention, by setting the interior of the steel reactor into an anaerobic zone, an aerobic zone, and an anoxic zone from bottom to top without physical partitions, and by using DO and ORP sensors to monitor the dissolved oxygen concentration and redox potential at different heights in real time, this device can utilize hydrodynamics and dissolved oxygen gradients to naturally form a stable vertical stratified structure of microorganisms. This solves the problem in the prior art where hard partitions disrupt the hydraulic flow field or the dissolved oxygen gradient is not accurately controlled, leading to mutual interference between anaerobic, aerobic, and anoxic bacteria, thereby improving the synergistic effect of nitrogen and phosphorus removal.

[0016] 3. In this invention, by setting up a water distribution support and an inclined water distribution pipe, the sewage forms a uniform swirling water inlet pattern at the bottom of the steel reactor, solving the problem of uneven water distribution leading to local hydraulic impact or dead zones. By setting up an air separator and its air inlet and outlet, this device can perform wind separation of the light flocs escaping from the top of the steel reactor, solving the problem of light sludge being lost with the effluent. By setting up a floc separation plate and its internal annular array of separation holes, this device can screen granular sludge and flocculent sludge, solving the problem of excessive flocculent sludge residue in the effluent system.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Example, refer to Figure 1 - Figure 8An integrated continuous flow vertical stratified A0A-AGS reactor device includes a steel reactor 1. The interior of the steel reactor 1 is arranged from bottom to top as follows: an anaerobic zone 101, an aerobic zone 1011, and an anoxic zone 1012. A notch is formed at the top of the outer wall of the steel reactor 1, and a guide slot 2 is formed inside the notch. The guide slot 2 has an arc-shaped structure, and an arc-shaped sealing plate 7011 is inserted into the guide slot 2. The sealing plate 7011 moves up and down along the guide slot 2. A recovery box 6011 is fixedly connected to the top of the sealing plate 7011. The recovery box 6011 has an arc-shaped box structure with an open top. A triangular effluent weir 7 is fixedly connected to the side of the recovery box 6011 near the inner wall of the steel reactor 1. The triangular effluent weir 7 moves up and down with the sealing plate 7011 and controls the flow of the steel reactor 1. The water in the reactor enters the recovery tank 6011. A wind separator 201 is fixedly connected to the top of the outer wall of the steel reactor 1. An air inlet 2011 is opened on the outer linear array of the wind separator 201. An inclined surface is opened on the right end of the wind separator 201, and an air outlet 2012 is set on the inclined surface. The sealing insert 7011 moves up and down along the guide slot 2, which drives the triangular water outlet weir 7 to move accordingly. This allows for precise control of the water level of the overflow in the steel reactor 1 into the recovery tank 6011, solving the problem of the difficulty in dynamically adjusting the water level under different operating conditions. A sludge return unit 3 is fixedly connected to the inner side of the steel reactor 1. The sludge return unit 3 includes a uniform sludge discharge structure. A DO sensor 301 and an ORP sensor 3011 are fixedly connected to the inner wall of the steel reactor 1. The ORP sensor 3011 is located above the DO sensor 301.

[0021] Furthermore, a water distribution support 4 is fixedly connected to the inner side of the steel reactor 1. The water distribution support 4 has a ring structure, and a water distribution pipe 401 is fixedly connected in a ring array on the inner wall of the water distribution support 4. The water distribution pipe 401 is inclined and communicates with the water distribution support 4. An inlet pipe 4011 is fixedly connected to the outer wall of the water distribution support 4. The inlet end of the inlet pipe 4011 extends outward from the steel reactor 1 and communicates with the water distribution support 4. An inlet pump 4012 is fixedly connected to the outer wall of the inlet pipe 4011. The inlet pump 4012 is used to control the flow of water into the water distribution support 4. The water flow velocity and flow rate of the part are controlled to generate directional airflow through the air inlet 2011 and air outlet 2012 on the air separator 201, which is used to separate the light flocs overflowing from the top of the steel reactor 1 by air force. This solves the problem of light sludge being lost with the effluent and affecting the effluent quality. An aeration support 5 is fixedly connected to the inner wall of the steel reactor 1. The aeration support 5 has a ring structure and is located above the water distribution support 4. An air inlet pipe 501 extending out of the steel reactor 1 is fixedly connected to the outer side of the aeration support 5. An air inlet pump 5011 is fixedly connected to the outer wall of the air inlet pipe 501.

[0022] Furthermore, a porous aeration disc 5012 is fixedly connected to the inner wall of the aeration support 5. Aeration holes 5013 are arranged in a ring array on the top surface of the porous aeration disc 5012. Both the aeration holes 5013 and the porous aeration disc 5012 are connected to the aeration support 5 and used for aeration towards the interior of the steel reactor 1, forming an aerobic zone 1011. A support base plate 6 is fixedly connected to the outer wall of the steel reactor 1. Two support base plates 6 are provided, symmetrically fixed to the outer wall of the steel reactor 1. Servo push rods 601 are fixedly connected to the top surface of each of the two support base plates 6. This enables real-time monitoring of dissolved oxygen and oxidation-reduction potential at different heights within the reactor using the sludge return unit 3 in conjunction with the DO sensor 301 and the ORP sensor 3011. This allows for precise control of the microbial environment in the anaerobic zone 101, aerobic zone 1011, and anoxic zone 1012, solving the problem of maintaining a stable dissolved oxygen gradient in the vertical direction. A support plate 6012 is fixedly connected to the top of the servo push rod 601. The support plate 6012 is fixedly set on the outer wall of the recovery box 6011. A flocculent sludge sorting plate 7012 is fixedly connected to the inner wall of the recovery box 6011. The flocculent sludge sorting plate 7012 has sorting holes in its internal annular array. This realizes the formation of a uniform swirling water inlet mode at the bottom of the reactor by using the annular water distribution support 4 in conjunction with the inclined water distribution pipe 401. This solves the problem of uneven water distribution causing local hydraulic impact or dead zones in the anaerobic zone 101. A connecting support plate 7013 is fixedly connected to the inner wall of the recovery box 6011. A connecting guide rod 7014 is fixedly connected to the bottom end of the connecting support plate 7013. A water immersion sensor 7015 is fixedly connected to the bottom end of the connecting guide rod 7014. The water immersion sensor 7015 is used to detect the water level inside the steel reactor 1 and is electrically connected to the servo push rod 601. A drain pipe 701 is fixedly connected to the outer side of the recovery box 6011.

[0023] In operation, the wastewater to be treated is first introduced into the inlet pipe 4011 via the inlet pump 4012 and then enters the annular water distribution support 4. An inclined array of water distribution pipes 401 is fixedly connected to the inner wall of the water distribution support 4. The wastewater is evenly released into the bottom area of ​​the steel reactor 1 through the water distribution pipes 401 in a swirling manner. This inlet method creates a uniform upward flow field at the bottom of the reactor, avoiding the impact of concentrated inlet flow on localized areas and providing a stable hydraulic environment for subsequent microbial zoning. The wastewater flows slowly from bottom to top inside the steel reactor 1. Since no aeration device is installed at the bottom of the reactor, the dissolved oxygen concentration in the bottom area is naturally maintained at a low level, thus forming the anaerobic zone 101. In the anaerobic zone 101, the wastewater is in full contact with the sludge at the bottom of the reactor. Microorganisms utilize the organic matter in the wastewater for anaerobic phosphorus release and hydrolysis acidification reactions, providing carbon sources and substrate conditions for the subsequent phosphorus uptake and denitrification processes in the aerobic zone 1011. As the wastewater continues to flow... The air flows upward and enters the aeration zone above the anaerobic zone 101. A ring-shaped aeration support 5 is fixedly connected in this zone. A porous aeration disc 5012 is fixedly connected to the inner wall of the aeration support 5. Aeration holes 5013 are arranged in a ring array on the top surface of the porous aeration disc 5012. External air is sent into the aeration support 5 through the air inlet pipe 501 and the air pump 5011, and then evenly released into the water body through the aeration holes 5013, forming the aerobic zone 1011. In the aerobic zone 1011, the dissolved oxygen concentration in the wastewater increases, and aerobic microorganisms multiply and metabolize in large quantities in this area, further degrading the organic matter in the wastewater. Simultaneously, ammonia nitrogen is oxidized to nitrate or nitrite, and the aerobic phosphorus uptake reaction is completed. Due to the inclined arrangement of the water distribution pipe 401 and the position design of the aeration discs, the upward flow velocity and aeration intensity are matched, keeping the microorganisms in the aerobic zone 1011 in suspension and gradually agglomerating into a granular structure, which is beneficial for the formation and maintenance of aerobic granular sludge. Above the aerobic zone 1011, the dissolved oxygen concentration in the water naturally decreases as the oxygen introduced by aeration is gradually consumed by microorganisms during its ascent, forming the anoxic zone 1012. In the anoxic zone 1012, microorganisms use nitrates or nitrites produced in the aerobic zone 1011 as electron acceptors to carry out denitrification, reducing nitrogen oxides to nitrogen gas which escapes from the water, thus completing nitrogen removal. The three zones—anaerobic, aerobic, and anoxic—are naturally connected vertically without the need for physical partitions. The dissolved oxygen gradient between the zones is naturally formed and remains relatively stable through hydraulic conditions and aeration intensity. A DO sensor 301 and an ORP sensor 3011 are fixedly connected to the inner wall of the steel reactor 1. The ORP sensor 3011 is located above the DO sensor 301. The two sensors monitor the dissolved oxygen concentration and oxidation-reduction potential of the aerobic zone 1011 and the anoxic zone 1012, respectively, providing real-time data to the external control system to adjust the aeration rate of the air pump 5011, thereby maintaining the environmental conditions required for microbial activity in each zone. After being treated in three functional zones, the water continues to rise to the upper part of the steel reactor 1. The upper part is equipped with an effluent and sludge screening structure. A notch is formed at the top of the outer wall of the steel reactor 1, and an arc-shaped guide slot 2 is formed inside the notch. An arc-shaped sealing plate 7011 is inserted into the guide slot 2. A recovery box 6011 is fixedly connected to the top of the sealing plate 7011. The recovery box 6011 is an arc-shaped box structure with an open top. A triangular effluent weir 7 is fixedly connected to the side of the recovery box 6011 closest to the inner wall of the steel reactor 1. The rising water overflows into the recovery box 6011 through the triangular effluent weir 7. The overflow height of the weir 7 determines the water level inside the reactor. By adjusting the position of the triangular outlet weir 7, the effluent flow rate and sludge settling time can be controlled to prevent the loss of a large amount of light sludge with the effluent. A support base plate 6 is fixedly connected to the outer wall of the steel reactor 1. A servo push rod 601 is fixedly connected to the top surface of the support base plate 6. The top of the servo push rod 601 is fixedly connected to the outer wall of the recovery box 6011 through the support top plate 6012. The servo push rod 601 drives the recovery box 6011 to move the sealing insert plate 7011 up and down along the guide slot 2, thereby driving the triangular outlet weir 7 to rise and fall synchronously, changing the overflow liquid level height of the water body. A connecting support plate 7013 is fixedly connected to the inner wall of the recycling bin 6011. A water level sensor 7015 is fixedly connected to the bottom end of the connecting support plate 7013 via a connecting guide rod 7014. The water level sensor 7015 extends into the steel reactor 1 and detects the water level. The water level sensor 7015 is electrically connected to a servo push rod 601. When the water level changes, the water level sensor 7015 transmits a signal to the servo push rod 601, which automatically adjusts the height of the recycling bin 6011 to ensure that the triangular outlet weir 7 is always in a suitable overflow position, thereby maintaining a relatively stable water level inside the reactor and preventing excessive sludge loss due to excessively high water levels. The treatment effect may be affected by the low water level. After the water enters the recycling tank 6011, it flows through the flocculent sludge sorting plate 7012 fixedly connected to the inner wall of the recycling tank 6011. The flocculent sludge sorting plate 7012 has sorting holes in the internal annular array. When the granular sludge and flocculent sludge in the water pass through the sorting holes, they are screened. Granular sludge with better settling performance is difficult to pass through the sorting holes due to its higher density and is retained in the steel reactor 1 to continue to participate in the reaction. Light flocculent sludge passes through the sorting holes with the water and is eventually discharged from the reactor. This screening mechanism helps to enrich aerobic granular sludge with good settling performance and improve the biomass concentration and reaction efficiency in the reactor. A wind separator 201 is fixedly connected to the top of the outer wall of the steel reactor 1. Air inlets 2011 are arranged in a linear array on the outer side of the wind separator 201. An inclined surface is provided at the right end of the wind separator 201, and an air outlet 2012 is provided on this inclined surface. External air enters the wind separator 201 through the air inlets 2011 and is then blown out from the air outlet 2012 in the form of a directional airflow. The airflow sweeps across the water surface at the top of the steel reactor 1, blowing away and collecting the light flocs escaping from the water surface, further reducing the possibility of flocculent sludge being lost with the effluent, and preventing the light flocs from accumulating and clogging the outlet. The inner side of the reactor 1 is fixedly connected to a sludge return unit 3. The sludge return unit 3 lifts the sludge deposited at the bottom of the steel reactor 1 to the top of the reactor, so that the sludge forms a circulation flow inside the reactor. On the one hand, it maintains the uniform sludge concentration in each area of ​​the reactor and prevents excessive accumulation of sludge at the bottom. On the other hand, it transports the sludge that has completed the phosphorus release reaction in the anaerobic zone 101 to the aerobic zone 1011 and the anoxic zone 1012, so that the microorganisms in the sludge experience different environmental conditions in sequence to complete the complete phosphorus release, phosphorus uptake and denitrification metabolic process, thereby achieving the simultaneous removal of carbon, nitrogen and phosphorus in wastewater.
