[0003] In the process of sewage treatment, it is usually necessary to perform anaerobic and aerobic treatment on the sewage to decompose the organic matter in the sewage, so that the treated sewage is not likely to cause eutrophication of natural water bodies after discharge.

[0004] In the prior art, in order not to occupy surface space, sewage treatment equipment is usually buried underground. Since the degradation of organic matter in sewage using anaerobic sludge particles and aerobic sludge particles will continue to produce more sludge particles, it is necessary to promptly treat the sludge particles generated during the sewage treatment process to prevent the sludge particles from clogging the sewage treatment equipment.

[0048] See also Figures 1 to 6The utility model provides an underground integrated sewage treatment equipment, including a box body 1, a plurality of partition plates 2 and a plurality of sludge lifting units 3. The partition plates are arranged in the box body 1 and can sequentially divide the interior of the box body 1 into an anaerobic tank 4, an aerobic tank 5 and an equipment cabin 6 along the length direction of the box body 1. The box body 1 is provided with a water inlet 11 connected to the anaerobic tank 4 and a water outlet 12 connected to the aerobic tank 5. An air pump 61 and a control unit 62 are arranged in the equipment cabin 6. An anaerobic tank 4 is provided with an anaerobic precipitation recess 41, an aerobic tank 5 is provided with an aerobic precipitation recess 51, and an aerobic tank 5 is also provided with an aeration pipe 58. The air pipe 58 extends along the aerobic bent flow channel, and the aeration pipe 58 is connected to the air pump 61 so as to evenly supply oxygen-containing gas to the aerobic tank 5, thereby improving the effect of aerobic treatment. In addition, it can be understood that three inspection ports 13 can be opened on the box body 1, and the anaerobic tank 4, the aerobic tank 5 and the equipment cabin 6 are each matched with an inspection port 13, so that the inspection port 13 can be connected with the interior of the anaerobic tank 4, the aerobic tank 5 and the equipment cabin 6 for convenient maintenance. In addition, the inspection port 13 corresponding to the aerobic tank 5 can also serve as exhaust, and the inspection port 13 corresponding to the equipment cabin 6 can also serve as air intake. Each sludge lifting unit 3 is inserted into the box body 1 from the top of the box body 1 and connected to the corresponding anaerobic precipitation recess 41 and / or aerobic precipitation recess 51, and the sludge lifting unit 3 is also electrically connected to the control unit 62, so that the sludge lifting unit 3 can be controlled by the control unit 62 to lift the anaerobic granular sludge in the anaerobic precipitation recess 41 and the aerobic granular sludge in the aerobic precipitation recess 51 upward and discharge them from the top of the box body 1 to the outside of the box body 1.

[0049] The underground integrated sewage treatment equipment of the utility model comprises an anaerobic tank 4, an aerobic tank 5 and an equipment cabin 6, so as to perform anaerobically and aerobically treatment on sewage, so that the organic matter content and solid impurities in the water discharged after treatment are less, and it is not easy to cause eutrophication of the water body, and the sewage treatment equipment has a higher degree of integration and occupies a small area, so as to be easily buried underground; the anaerobic precipitation depression 41 in the anaerobic tank 4 and the aerobic precipitation depression 51 in the aerobic tank 5 are both suitable for storing sludge particles settled in the tank, and the sludge lifting unit 3 is connected with the anaerobic precipitation depression 41 and the aerobic precipitation depression 51, so as to timely lift the sludge particles in the anaerobic precipitation depression 41 and the aerobic precipitation depression 51 upward and discharge them from the top of the box body 1 to the outside of the box body 1 for treatment, so that the sludge particles will not be directly discharged into the underground pipeline, causing the underground pipeline to be blocked.

[0050] Furthermore, if Figure 2As shown, the anaerobic tank 4 may be provided with a plurality of anaerobic baffles 42 which are parallel to each other and vertically arranged, so that the internal space of the anaerobic tank 4 is divided into an anaerobic bending flow channel through the anaerobic baffles 42, and an anaerobic overflow port is provided at the top of a section of the anaerobic bending flow channel close to the aerobic tank 5, and an anaerobic filtration structure 43 needs to be provided at the anaerobic overflow port. The sewage enters the anaerobic tank 4 from the water inlet 11 and can flow along the anaerobic bending flow channel, so that the sewage has a longer flow path, so that the anaerobic treatment can be more sufficient and the anaerobic treatment effect can be better. The sewage after anaerobic treatment can flow through the anaerobic overflow port into the aerobic tank 5, and the corresponding anaerobic granular sludge will remain in the anaerobic tank 4 under the filtering action of the anaerobic filtration structure 43 to prevent interference with the subsequent aerobic treatment.

[0051] See also Figure 4 As a specific embodiment of the present invention, an anaerobic tank 4 in the present invention is further provided with an anaerobic stirring unit, which specifically includes an anaerobic disturbance scraper 44, an anaerobic stirring screw 45 and an anaerobic stirring drive motor 46. The aperture of the anaerobic disturbance scraper 44 is less than or equal to the diameter of the formed anaerobic granular sludge, so that the unformed or flocculent anaerobic granular sludge can freely pass through the mesh of the anaerobic disturbance scraper 44, while the formed anaerobic granular sludge cannot pass through the mesh of the anaerobic disturbance scraper 44. The scraper 44 is provided with a slot suitable for inserting the anaerobic baffle 42, so that the anaerobic disturbance scraper 44 can be longitudinally inserted into the bottom of the anaerobic tank 4. The anaerobic stirring screw 45 is rotatably arranged on the top of the anaerobic tank 4, and the anaerobic stirring screw 45 is parallel to the plate surface of each anaerobic baffle 42. Based on the above-mentioned design of the anaerobic stirring screw 45, an anaerobic precipitation recess 41 can be formed at a position corresponding to the lower side of the two ends of the anaerobic stirring screw 45 in the anaerobic tank 4.

[0052] The top of the anaerobic disturbance scraper 44 is screwed to the anaerobic stirring screw 45, and the anaerobic stirring screw 45 is connected to the anaerobic stirring drive motor 46 for driving the anaerobic stirring screw 45 to rotate forward or reversely via the anaerobic stirring drive motor 46. When the anaerobic stirring screw 45 rotates, the anaerobic disturbance scraper 44 can move along the axial direction of the anaerobic stirring screw 45, so as to stir the sewage and anaerobic granular sludge in the anaerobic tank 4 during the movement, so that the unformed anaerobic granular sludge can be fully mixed with the sewage, thereby improving the effect of anaerobic treatment, and the formed anaerobic granular sludge will be stopped by the anaerobic disturbance scraper 44 in the anaerobic tank 4 and move along the moving direction of the anaerobic disturbance scraper 44 toward the anaerobic precipitation recessed parts 41 at both ends of the anaerobic tank 4.

[0053] Similar to the anaerobic tank 4, the aerobic tank 5 may be provided with a plurality of aerobic baffles 52 which are parallel to each other and vertically arranged, so that the internal space of the aerobic tank 5 is divided into an aerobic bending flow channel through the aerobic baffles 52, and an aerobic overflow port is provided at the top of a section of the aerobic bending flow channel close to the equipment cabin 6, and an aerobic filtering structure 53 is provided at the aerobic overflow port, and an aerobic water outlet pool 54 is also provided on one side of the aerobic overflow port close to the equipment cabin 6, and the water outlet 12 is connected to the aerobic water outlet pool 54. The sewage flows into the aerobic tank 5 from the anaerobic overflow port and can flow along the aerobic curved flow channel, so that the sewage has a longer flow path, thereby making the aerobic treatment more complete and the aerobic treatment effect better. The sewage after aerobic treatment can flow into the aerobic outlet tank 54 through the aerobic overflow port and flow out from the outlet 12, and the corresponding aerobic granular sludge will remain in the aerobic tank 5 under the filtering action of the aerobic filtration structure 53, so that there are fewer impurities in the water discharged from the outlet 12.

[0054] Furthermore, an aerobic stirring unit is also provided in the aerobic tank 5, and the aerobic stirring unit includes an aerobic disturbance scraper 55, an aerobic stirring screw 56 and an aerobic stirring drive motor 57. The aperture of the aerobic disturbance scraper 55 is less than or equal to the diameter of the formed aerobic granular sludge, so that the unformed or flocculent aerobic granular sludge can freely pass through the mesh of the aerobic disturbance scraper 55, while the formed aerobic granular sludge cannot pass through the aerobic disturbance scraper 55. The aerobic disturbance scraper 55 is provided with a slot suitable for inserting the aerobic baffle 52, so that the aerobic disturbance scraper 55 can be longitudinally inserted into the bottom of the aerobic tank 5. The aerobic stirring screw 56 is rotatably arranged on the top of the aerobic tank 5, and the aerobic stirring screw 56 is parallel to the plate surface of each aerobic baffle 52. Based on the above-mentioned design of the aerobic stirring screw 56, an aerobic precipitation depression 51 can be formed at a position corresponding to the lower side of the two ends of the aerobic stirring screw 56 in the aerobic tank 5.

[0055] The top of the aerobic disturbance scraper 55 is screwed to the aerobic stirring screw 56, and the aerobic stirring screw 56 is connected to the aerobic stirring drive motor 57 for driving the aerobic stirring screw 56 to rotate forward or reversely via the aerobic stirring drive motor 57. When the aerobic stirring screw 56 rotates, the aerobic disturbance scraper 55 can move along the axial direction of the aerobic stirring screw 56, so as to stir the sewage and aerobic granular sludge in the aerobic tank 5 during the movement, so that the unformed aerobic granular sludge can be fully mixed with the sewage, thereby improving the effect of aerobic treatment, and the formed aerobic granular sludge will be stopped by the aerobic disturbance scraper 55 in the aerobic tank 5 and move along the moving direction of the anaerobic disturbance scraper 44 toward the aerobic precipitation recesses 51 at both ends of the aerobic tank 5.

[0056] Furthermore, if Figures 2 to 5As shown, an anti-agitation cover plate 7 may be provided at the upper end of the anaerobic sedimentation depression 41 and the aerobic sedimentation depression 51. A material passage is provided on the anti-agitation cover plate 7. A plurality of strip plates 71 are provided at the material passage. The length direction of each strip plate 71 is perpendicular to the flow direction of the sewage. Each strip plate 71 gradually tilts upward in the flow direction of the sewage to form a gap suitable for the granular sludge to pass through between two adjacent strip plates 71. When the sewage passes through the anti-agitation cover plate 7, it will be blocked by the strip plates 71. Only a small part of the sewage will enter the corresponding anaerobic sedimentation depression 41 or the aerobic sedimentation depression 51 at a relatively small flow rate, so that the granular sludge entering the sedimentation depression will not be easily agitated again.

[0057] Specifically, Figure 4 and Figure 6 As shown, the sludge lifting unit 3 can be specifically configured to include a lifting pipe 31, a lifting screw 32 and a lifting motor 33. One end of the lifting pipe 31 is connected to the anaerobic precipitation recess 41 or the aerobic precipitation recess 51. The lifting screw 32 is inserted into the lifting pipe 31 and one end of the lifting screw 32 extends into the anaerobic precipitation recess 41 or the aerobic precipitation recess 51. The other end of the lifting screw 32 is transmission-connected to the lifting motor 33. The lifting motor 33 can drive the lifting screw 32 to rotate, so as to lift the anaerobic granular sludge or the aerobic granular sludge upward along the lifting pipe 31 and discharge it into the box 1. In addition, it can be understood that the lifting pipe 31 can be arranged vertically, and the lifting motor 33 can be arranged to drive the lifting screw 32 to rotate at a relatively low speed, so that in the process of driving the anaerobic granular sludge or the aerobic granular sludge upward along the lifting pipe 31, it is not easy to bring out the sewage. In order to ensure that the anaerobic granular sludge or the aerobic granular sludge and the upper surface of the spiral structure of the lifting screw 32 are not easily moved relative to each other, a stopping mesh plate 321 can be arranged on the upper surface of the spiral structure of the lifting screw 32 to stop the anaerobic granular sludge or the aerobic granular sludge via the stopping mesh plate 321.

[0058] In addition, a connecting tank 8 can be set between the anaerobic tank 4 and the aerobic tank 5. The connecting tank 8 includes a connecting side and an overflow side. The connecting side is connected to the anaerobic overflow port, and the overflow side is connected to the aerobic tank 5. The lifting pipe 31 runs through the connecting tank 8 and extends to the anaerobic precipitation recess 41 or the aerobic precipitation recess 51. The lifting pipe 31, that is, the sludge lifting unit 3 is set at the connecting tank 8. The lifting pipe 31 will not occupy the space in the anaerobic tank 4 or the aerobic tank 5, thereby facilitating the movement of the anaerobic disturbance scraper 44 and the aerobic disturbance scraper 55, and also facilitating the installation of the anaerobic filtration structure 43.

However, the present invention is not limited to the specific details in the above embodiments.
