[0051] See also Figure 1 The utility model provides an integrated aerobic granular sludge sewage treatment device, comprising a tank body 1 and a partition plate 2, wherein the partition plate 2 is used to separate the interior of the tank body 1 into an anaerobic zone and an aerobic zone, and a water supply pipe 21 extending to the aerobic zone is formed on the partition plate 2 to achieve communication between the anaerobic zone and the aerobic zone.

[0052] Specifically, an anaerobic tank 3 is provided in the anaerobic zone. The anaerobic tank 3 can be specifically configured to include a tank body 31, a water inlet pipe 32, an anaerobic granular sludge discharge pipe 33 and an anaerobic zone water outlet 34. The anaerobic zone water outlet 34 is opened at the upper part of the anaerobic tank 3. A water gap is formed between the outer wall of the anaerobic tank 3 and the inner wall of the tank body 1. After the sewage enters the anaerobic tank 3 from the water inlet pipe 32, it can flow out from the anaerobic zone water outlet 34 and flow through the water gap to enter the aerobic zone. The tank body 1 is connected to a water outlet pipe 11 and an aerobic granular sludge discharge pipe 12 connected to the aerobic zone, and an exhaust port 13 is opened on the top of the tank body 1. An air supply unit 4 is provided in the aerobic zone to supply oxygen-containing gas into the aerobic zone via the air supply unit 4, so as to maintain the oxygen content in the sewage in the aerobic zone.

[0053] An exhaust port 13 needs to be opened at the top of the tank body 1 so that gases such as methane generated during the anaerobic treatment process can be discharged through the exhaust port 13, so as to maintain the pressure balance inside and outside the tank body 1 of the aerobic granular sludge sewage treatment integrated equipment. Similarly, the oxygen-containing gas overflowing from the aerobic zone into the anaerobic zone can also be discharged in time through the exhaust port 13, thereby ensuring that the amount of oxygen-containing gas dissolved in the sewage in the anaerobic zone is small, so as to ensure that the anaerobic zone is not easily disturbed by the aerobic zone. In addition, the oxygen-containing gas can be discharged from the exhaust port 13 through the water gap from the water outlet of the water supply pipe 21. In the process of the oxygen-containing gas moving upward, it can fully contact with the sewage that has been anaerobically treated, thereby increasing the oxygen content in the sewage, so as to facilitate better aerobic treatment.

[0054] Furthermore, a containing chamber suitable for containing sewage and anaerobic granular sludge is formed in the tank body 31 of the anaerobic tank 3, and a first partition plate 311 and a connecting pipe 312 are provided in the containing chamber. The first partition plate 311 itself can be enclosed to form an anaerobic filtration chamber, an anaerobic zone water outlet 34 is provided at the upper part of the anaerobic reaction chamber, a connecting port is provided at the bottom of the anaerobic reaction chamber, an anaerobic reaction chamber is formed between the first partition plate 311 and the inner wall of the tank body 31, a water inlet pipe 32 is connected to the anaerobic reaction chamber, the bottom of the anaerobic reaction chamber is connected to the anaerobic granular sludge discharge pipe 33, the bottom end of the connecting pipe 312 is provided at the bottom of the anaerobic reaction chamber, the top end of the connecting pipe 312 extends through the connecting port into the anaerobic filtration chamber, and an anaerobic zone reflux channel is formed between the connecting port and the connecting pipe 312.

[0055] After the sewage enters the anaerobic tank 3 from the water inlet pipe 32, it first enters the anaerobic reaction chamber to anaerobically treat the sewage through the anaerobic granular sludge in the anaerobic reaction chamber. During the anaerobic treatment process, the newly formed (i.e., already granulated) anaerobic granular sludge will be deposited at the bottom of the anaerobic reaction chamber to enter the anaerobic granular sludge discharge pipe 33. It can be understood that an electric-controlled gate can be provided at the outlet end of the anaerobic granular sludge discharge pipe 33, so that the anaerobic granular sludge in the anaerobic granular sludge discharge pipe 33 can be discharged in time by controlling the intermittent opening and closing of the electric-controlled gate. In the process of anaerobic treatment, the newly formed unformed anaerobic sludge is deposited at the bottom of the anaerobic reaction chamber to enter the anaerobic granular sludge discharge pipe 33. The anaerobic granular sludge (that is, the anaerobic granular sludge that has not formed into granules and is still in flocculent form) will enter the anaerobic filter chamber along the connecting pipe 312 under the action of the sewage flow, so as to carry out the final anaerobic treatment on the sewage in the anaerobic filter chamber. Subsequently, the unformed anaerobic granular sludge and the formed anaerobic granular sludge in the anaerobic filter chamber will enter the anaerobic reaction chamber again along the anaerobic zone reflux channel under the action of gravity to continue the anaerobic treatment of the sewage, thereby forming the recycling of anaerobic granular sludge and the timely treatment of failed anaerobic granular sludge, thereby eliminating the need to frequently add new anaerobic granular sludge, which prolongs the maintenance period of the equipment.

[0056] Furthermore, a second partition plate 313 and a third partition plate 314 are further provided in the accommodating chamber of the anaerobic tank 3. The second partition plate 313 is provided between the first partition plate 311 and the inner wall of the tank body 31, so as to form a first anaerobic reaction chamber between the first partition plate 311 and the second partition plate 313, and the water inlet pipe 32 is communicated with the first anaerobic reaction chamber. The third partition plate 314 is provided between the second partition plate 313 and the inner wall of the tank body 31, and the bottom of the third partition plate 314 is connected to the outer wall of the connecting pipe 312, so as to form a second anaerobic reaction chamber between the second partition plate 313 and the third partition plate 314, and a third anaerobic reaction chamber is formed between the third partition plate 314 and the inner wall of the tank body 31. The bottom of the first anaerobic reaction chamber extends to the bottom of the second anaerobic reaction chamber and is communicated with the second anaerobic reaction chamber. An overflow port is provided on the upper part of the second partition plate 313, so as to be communicated with the third anaerobic reaction chamber via the overflow port, and the anaerobic granular sludge discharge pipe 33 is communicated with the third anaerobic reaction chamber.

[0057] Based on the above structure, the sewage will first enter the first anaerobic reaction chamber, then enter the second anaerobic reaction chamber from the bottom of the first anaerobic reaction chamber, and gradually rise in the second anaerobic reaction chamber to overflow from the overflow port at the top of the second anaerobic reaction chamber into the third anaerobic reaction chamber, thereby extending the flow path of the sewage in the anaerobic reaction chamber to obtain a better anaerobic treatment effect, and the sewage entering the third anaerobic reaction chamber will enter the anaerobic filter chamber along the connecting pipe 312 under the action of the sewage flow, so as to perform the final anaerobic treatment on the sewage in the anaerobic filter chamber, and then the unformed anaerobic granular sludge and the formed anaerobic granular sludge in the anaerobic filter chamber will enter the anaerobic reaction chamber again along the anaerobic zone reflux channel under the action of gravity to continue to perform anaerobic treatment on the sewage to achieve circulation.

[0058] Furthermore, an anaerobic zone filter structure 341 is required to be provided at the anaerobic zone water outlet 34, and an anaerobic zone water diversion structure 3121, such as a conical water diversion plate, can be provided at the top of the connecting pipe 312, the tip of the conical water diversion plate is toward the water outlet at the top of the connecting pipe 312, and the round bottom end of the conical water diversion plate is toward the anaerobic zone water outlet 34, so that the sewage entering the anaerobic filtration chamber can be evenly distributed through the anaerobic zone water diversion structure 3121, so as to prevent all the sewage from rushing to one position of the anaerobic zone filter structure 341, causing local blockage of the anaerobic zone filter structure 341. In addition, a guide ring 3122 can be provided on the outer wall of the connecting pipe 312 in the first anaerobic reaction chamber, so that the anaerobic granular sludge refluxed from the anaerobic zone reflux channel to the first anaerobic reaction chamber can be evenly distributed in the first anaerobic reaction chamber under the action of the guide ring 3122, so that the anaerobic treatment of the sewage in the first anaerobic reaction chamber can be more uniform.

[0059] In addition, it should be noted that the vertical height of the overflow port should be less than or equal to the vertical height of the connecting port to ensure that the sewage entering the first anaerobic reaction chamber will preferentially overflow from the second anaerobic reaction chamber to the third anaerobic reaction chamber, so as to reduce the situation where the sewage directly enters the anaerobic filtration chamber in the second anaerobic reaction chamber from the first anaerobic reaction chamber, resulting in poor anaerobic treatment effect.

[0060] Furthermore, a first enclosure 5 and a second enclosure 6 are provided in the aerobic zone. Specifically, the top of the first enclosure 5 is connected to the partition plate 2, and the bottom of the first enclosure 5 is connected to the bottom wall of the tank body 1, so as to enclose and form a first aerobic reaction chamber suitable for accommodating sewage and aerobic granular sludge. The water supply pipe 21 is communicated with the first aerobic reaction chamber. The second enclosure 6 is provided between the first enclosure 5 and the side wall of the tank body 1, and the top of the second enclosure 6 is connected to the partition plate 2, and the bottom of the second enclosure 6 is connected to the bottom wall of the tank body 1, so as to form a second aerobic reaction chamber between the first enclosure 5 and the second enclosure 6.

It can be understood that an electric control gate needs to be provided at the discharge end of the aerobic granular sludge discharge pipe 12, so that the aerobic granular sludge in the aerobic granular sludge discharge pipe 12 can be discharged in time by controlling the intermittent opening and closing of the electric control gate. The above design enables the sewage after anaerobic treatment to pass through the first aerobic reaction chamber and the second aerobic reaction chamber in sequence and be discharged from the aerobic filtration chamber through the outlet pipe 11, and the aerobic treatment has been completed, and the aerobic granular sludge generated by the aerobic treatment can be discharged from the aerobic granular sludge discharge pipe 12 in time.

[0061] Furthermore, the air supply unit 4 can be configured to include multiple air supply nozzles, and the multiple air supply nozzles are evenly distributed at the bottom of the first aerobic reaction chamber, so that the oxygen-containing gas can be evenly supplied to the first aerobic reaction chamber, so that the aerobic treatment of the sewage is more uniform; the water outlet end of the water supply pipe 21 is arranged at the top of the first aerobic reaction chamber, so that the oxygen-containing gas in the first aerobic reaction chamber overflows into the water gap, so that the sewage in the water gap can fully contact with the sewage that has been anaerobically treated, thereby increasing the oxygen content in the sewage, so as to better perform aerobic treatment, and an aerobic separation structure 14 is provided at the water outlet end of the water supply pipe 21, so that the sewage can be evenly introduced into the first aerobic reaction chamber through the aerobic separation structure 14, so that the sewage can be evenly mixed with the aerobic granular sludge, so that the effect of aerobic treatment is better.

[0062] Furthermore, a first aerobic reaction chamber water outlet 51 is provided at the upper portion of the first enclosure 5, and a second aerobic reaction chamber water outlet 61 is provided at the lower portion of the second enclosure 6. It should be noted that the position of the first aerobic reaction chamber water outlet 51 should be lower than the water outlet end of the water supply pipe 21 to ensure that the sewage can smoothly flow from the first aerobic reaction chamber water outlet 51 into the second aerobic reaction chamber, and a sludge drainage plate 62 is spirally wound on the inner wall of the second enclosure 6, so that the mixture of sewage and aerobic granular sludge flows from the first aerobic reaction chamber water outlet 51 to the second aerobic reaction chamber water outlet 61. During the process, it can rotate under the guidance of the sludge drainage plate 62, so that the formed aerobic sludge particles in the sewage hit the inner wall of the second enclosure 6 under the action of centrifugal force, and fall on the upper surface of the sludge drainage plate 62, and then move along the sludge drainage plate 62 to the bottom of the second aerobic reaction chamber, and a collecting cavity 15 is provided at a position relative to the lower end of the sludge drainage plate 62 at the bottom of the second aerobic reaction chamber to collect the formed aerobic sludge particles, and the aerobic granular sludge discharge pipe 12 is connected to the collecting cavity 15 to facilitate the discharge of aerobic sludge particles.

[0063] Furthermore, an aerobic zone filter structure 7 is provided at the upper part of the aerobic filter chamber, and a plurality of drainage tubes 8 are provided between the first aerobic reaction chamber and the aerobic filter chamber, one end of each drainage tube 8 is connected to the first aerobic reaction chamber, and the other end of each drainage tube 8 is connected to the aerobic filter chamber, and the port of the drainage tube 8 connected to the aerobic filter chamber is provided below the aerobic zone filter structure 7, and a diverter ring plate 63 is connected to the outer wall of the second enclosure 6 below the port of the drainage tube 8, so as to drain the aerobic granular sludge below the aerobic zone filter structure 7 into the first aerobic reaction chamber via the diverter ring plate 63 and the drainage tube 8, so that the aerobic sludge particles filtered by the aerobic zone filter structure 7 can fall onto the diverter ring plate 63 and then can flow back to the first aerobic reaction chamber through the drainage tube 8 to continue the reaction, thereby realizing the automatic circulation of aerobic granular sludge without the need for frequent addition of aerobic granular sludge.
