Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering.

[0003] Wastewater ecological purification systems are needed for water environment treatment. Existing wastewater ecological purification systems consist of equalization tanks, anaerobic tanks, aerobic tanks, and secondary sedimentation tanks. The purification process is carried out through the cooperation of each part. However, when the membrane fibers of the MBR membrane bioreactor in the aerobic tank of the existing purification system break, a large amount of wastewater will enter the reactor channel, causing the reactor channel to be contaminated and making the subsequent reactors unable to be used normally.

[0004] Therefore, it is necessary to invent a wastewater ecological purification system for water environment management to solve the above problems. Summary of the Invention

[0011] Furthermore, the recoil assembly includes: a horizontal tube, a connecting tube, a straight tube, and a sealing assembly;

[0012] The horizontal tubes are installed inside the support, and the number and position of the horizontal tubes correspond to the pipes. The horizontal tubes and aeration tubes are connected by connecting pipes. An air injection port is provided on the outside of the connecting pipes. The straight tubes are fixedly installed at equal intervals on the outside of the horizontal tubes. The straight tubes are connected to the horizontal tubes. One end of the straight tube extends into the inside of the pipe and corresponds to the position of the joint. The straight tubes are fixedly connected to the pipes.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0031] This invention provides a wastewater ecological purification system for water environment treatment, such as... Figures 1 to 6 As shown, it includes: a treatment tank 1, and inside the treatment tank 1, from left to right, there are an equalization tank 2, an anaerobic tank 3, an aerobic tank 4, and a secondary sedimentation tank 5. Inside the aerobic tank 4, there is an anti-fouling membrane reactor. The anti-fouling membrane reactor can treat sewage and prevent sewage from entering its internal channels after the membrane fibers break.

[0032] The equalization tank 2, anaerobic tank 3, aerobic tank 4, and secondary sedimentation tank 5 are the equalization tank, anaerobic tank, aerobic tank, and secondary sedimentation tank in the existing integrated sewage treatment equipment. The specific working principle will not be described in detail here.

[0033] The anti-fouling membrane reactor includes: support frame 6, pipes 7, sealing plate 8, membrane fibers 9, aeration pipe 16, extraction equipment, and anti-intrusion components;

[0034] The support frame 6 is installed inside the aerobic tank 4. The support frame 6 has a channel inside. Pipes 7 are symmetrically and equidistantly fixed inside the support frame 6 and are connected to the channel. The sealing plate 8 is fixedly installed on the side of the pipe 7 near the center of the support frame 6. Membrane fibers 9 are equidistantly arranged between opposite sealing plates 8. Aeration pipes 16 are equidistantly arranged inside the lower part of the support frame 6. The extraction device is located on the top of the support frame 6 and is connected to the channel. The extraction device is a water pump. The anti-intrusion component can prevent sewage from entering the membrane fibers 9.

[0035] In use, the wastewater in the aerobic tank 4 is extracted by the extraction equipment, so that the wastewater is filtered through the membrane pores of the membrane fiber 9 and enters the membrane fiber 9. Then, it is pumped away by the extraction equipment through the pipe 7 and the channel and injected into the secondary sedimentation tank 5. By injecting airflow into the aeration pipe 16, the oxygen in the airflow enters the wastewater in the aerobic tank 4 to assist in wastewater treatment. When the membrane fiber 9 breaks, the anti-intrusion component treats the broken membrane fiber 9 to prevent wastewater from entering the channel through the broken end of the membrane fiber 9 and contaminating the channel.

[0036] like Figures 2 to 6 As shown, the anti-intrusion assembly includes: housing 10, slide bar 11, ring plate 12, push ring 13, spring 14, connector 15, and recoil assembly;

[0037] The housing 10 is slidably sleeved on the outside of the membrane filament 9. The housing 10 is threadedly connected to the sealing plate 8. The slide rod 11 slides symmetrically through the housing 10. The ring plate 12 is fixedly sleeved on the outside of the membrane filament 9. The ring plate 12 is fixedly connected to the slide rod 11. The push ring 13 is located inside the pipe 7. The push ring 13 is fixedly connected to the slide rod 11. The connector 15 is fixedly connected to one end of the membrane filament 9 located inside the pipe 7. The connector 15 is fixedly connected to the push ring 13. The spring 14 is sleeved on the outside of the slide rod 11. The two ends of the spring 14 are fixedly connected to the housing 10 and the push ring 13 respectively. The ring plate 12 and the housing 10 are connected by a telescopic cover 26. The backwash assembly can inject airflow into the interior of the membrane filament 9.

[0038] When in use, if the membrane fiber 9 is intact, the spring 14 is in a compressed state. When the membrane fiber 9 breaks, the compressed spring 14 pushes the push ring 13, connector 15, slide rod 11, ring plate 12, and membrane fiber 9 to move, causing the two parts of the broken membrane fiber 9 to move away from each other. Subsequently, in conjunction with the backflushing assembly, airflow can be injected into the membrane fiber 9. The continuously injected airflow backflushes the membrane fiber 9, causing the sewage inside the membrane fiber 9 to be flushed outward, preventing external sewage from entering the membrane fiber 9 and thus preventing it from entering the pipe 7 and the channel. When the membrane fiber 9 needs to be replaced later, the backflushing assembly continuously injects airflow to prevent sewage from accumulating inside the membrane fiber 9, thus preventing sewage accumulated inside the membrane fiber 9 from entering the pipe 7 when replacing the membrane fiber 9.

[0039] like Figures 2 to 6 As shown, the backflush assembly includes: a horizontal pipe 17, a connecting pipe 18, a straight pipe 19, and a sealing assembly;

[0040] The horizontal pipe 17 is installed inside the support 6. The number and position of the horizontal pipe 17 correspond to the pipe 7. The horizontal pipe 17 and the aeration pipe 16 are connected by the connecting pipe 18. The connecting pipe 18 is provided with an air injection port on the outside. The straight pipe 19 is fixedly installed at equal intervals on the outside of the horizontal pipe 17. The straight pipe 19 is connected to the horizontal pipe 17. One end of the straight pipe 19 extends into the inside of the pipe 7 and corresponds to the position of the connector 15. The straight pipe 19 is fixedly connected to the pipe 7. The sealing component is installed inside the straight pipe 19. The sealing component can seal the straight pipe 19. The end of the connector 15 is provided with pointed cone blocks 23 that can break the sealing component at equal intervals.

[0041] Connect the air inlet to an external aerator. The aerator injects airflow into the connecting pipe 18, horizontal pipe 17, and aeration pipe 16 through the air inlet. The airflow enters the sewage through the pores on the surface of the aeration pipe 16 to provide oxygen. Due to the sealing of the straight pipe 19, the airflow cannot enter the pipe 7. When the connector 15 moves, it carries the pointed cone 23 with it. Finally, the pointed cone 23 breaks open the sealing component, and the airflow enters the connector 15 and the membrane fiber 9 through the straight pipe 19 for backflushing.

[0042] like Figure 5 and Figure 6 As shown, the enclosure assembly includes: a fixing tube 20, a support 21, a sealing membrane 22, and a retractable assembly;

[0043] The fixed tube 20 is threaded to one end of the straight tube 19 located inside the pipe 7. The support 21 is fixedly installed inside the fixed tube 20. The sealing membrane 22 is fixedly connected inside the support 21. The retractable component can prevent the sealing membrane 22 from entering the membrane fiber 9 and blocking the channel of the membrane fiber 9 after the sealing membrane 22 is damaged. The strength of the sealing membrane 22 can ensure that it will not be broken by the airflow. When the membrane fiber 9 is not broken, the pointed cone block 23 cannot contact the sealing membrane 22.

[0044] After the membrane fiber 9 breaks, when the push ring 13, connector 15 and membrane fiber 9 move, the push ring 13 moves to contact the fixed tube 20. At this time, the connector 15 contacts the support 21, and the pointed cone block 23 punctures the edge of the sealing membrane 22. At this time, the connection between the sealing membrane 22 and the support 21 is canceled. The retracting assembly retracts the sealing membrane 22, so as to prevent the sealing membrane 22 from entering the membrane fiber 9 and blocking the channel of the membrane fiber 9. At this time, the airflow can enter the membrane fiber 9 for backflow.

[0045] like Figure 5 and Figure 6 As shown, the retractable assembly includes: a circular block 24 and an elastic cord 25;

[0046] The round block 24 is fixedly installed in the middle of the sealing membrane 22, and the elastic rope 25 fixes the round block 24 to the fixing tube 20.

[0047] After the airflow enters the straight pipe 19, it impacts the sealing membrane 22 and the round block 24, causing the sealing membrane 22 to tighten. At this time, the tension rope 25 is in a stretched state. When the edge of the sealing membrane 22 is punctured and separated from the support 21, the sealing membrane 22 is impacted by the airflow and is in a retracted state, which reduces the contact area between the sealing membrane 22 and the airflow. The tension rope 25 recovers, causing the round block 24 and the sealing membrane 22 to move. Finally, the round block 24 and the sealing membrane 22 come into contact with the inner wall of the fixed pipe 20, so that the sealing membrane 22 will not enter the interior of the membrane filament 9, thus avoiding clogging the membrane filament 9.

[0048] like Figure 5 As shown, the push ring 13 and the fixed tube 20 are each provided with a matching inclined surface at their opposite ends.

[0049] By setting the bevel, the sealing of the contact point can be improved after the push ring 13 comes into contact with the fixed tube 20, thus preventing air leakage.

[0050] like Figure 5 As shown, the membrane pores on the membrane filament 9 are distributed in the region between two opposing annular plates 12.

[0051] This allows impurities in wastewater to be filtered through the membrane pores, thus achieving the filtration of impurities.

[0052] The spring 14 is galvanized. The elastic force of the spring 14 can quickly push the push ring 13 down to contact the fixed tube 20 after the diaphragm wire 9 breaks, and can also work with the pointed cone block 23 to cut the edge of the sealing membrane 22.

[0053] Working principle: Wastewater is treated after passing through equalization tank 2, anaerobic tank 3, aerobic tank 4, and secondary sedimentation tank 5;

[0054] Wastewater in aerobic tank 4 is extracted by an extraction device, allowing it to be filtered through the membrane pores of membrane fiber 9 before entering the membrane fiber 9. It is then pumped into secondary sedimentation tank 5 through pipe 7 and channel. The air injection port is connected to an external aerator, which injects airflow into connecting pipe 18, horizontal pipe 17, and aeration pipe 16 through the air injection port. The airflow enters the wastewater through the pores on the surface of aeration pipe 16 to provide oxygen. Due to the closure of straight pipe 19, the airflow cannot enter pipe 7. The oxygen in the airflow enters the wastewater in aerobic tank 4 to assist in wastewater treatment.

[0055] When the membrane filament 9 breaks, the compressed spring 14 pushes the push ring 13, connector 15, slide rod 11, ring plate 12, and membrane filament 9 to move, causing the two parts of the broken membrane filament 9 to move away from each other. The push ring 13 moves until it contacts the fixed tube 20, and the connector 15 contacts the support 21. The pointed block 23 punctures the edge of the sealing membrane 22. After the edge of the sealing membrane 22 is punctured and separated from the support 21, the sealing membrane 22 is impacted by the airflow and retracts, reducing the contact area between the sealing membrane 22 and the airflow. The tension rope 25 returns to its original state, causing the circular block 24 and the sealing membrane 22 to move. The final round block 24 and the sealing membrane 22 abut against the inner wall of the fixed pipe 20, so that the sealing membrane 22 will not enter the interior of the membrane fiber 9, thus avoiding clogging the membrane fiber 9. The continuously injected airflow enters the connector 15 and the interior of the membrane fiber 9 through the straight pipe 19, and backflushes, so that the sewage inside the membrane fiber 9 is flushed outward, preventing external sewage from entering the membrane fiber 9, and thus preventing it from entering the pipe 7 and the channel. When the membrane fiber 9 needs to be replaced later, the continuous injection of airflow will prevent sewage from accumulating inside the membrane fiber 9, thus preventing the sewage accumulated inside the membrane fiber 9 from entering the pipe 7 when replacing the membrane fiber 9.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
