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

[0020] Example 1 like Figures 1 to 3 As shown, this embodiment provides an AnMBR wastewater treatment system, including a membrane tank 1, a support frame 2, and two sets of symmetrically distributed membrane modules 3. The membrane module 3 includes a support plate 301 slidably connected to the support frame 2. Multiple membrane tubes 302 are fixed on the support plate 301. The free ends of the membrane tubes 302 are connected to pipes 303 fixedly connected to the support frame 2. The multiple pipes 303 are connected to a permeate pipe 305. A pipe connector 306 is connected to the permeate pipe 305 for quick connection to a permeate pump.

[0021] The bottom of the support frame 2 is provided with a bubble generating component 6, which includes multiple parallel conduits 601. Multiple venturi tubes 602 are provided on the conduits 601. The free ends of the venturi tubes 602 are connected to a porous circular plate 603 for generating nanobubbles.

[0022] In use, first, the wastewater pretreated by the previous process is injected into the membrane pool 1, while ensuring that the membrane pool 1 is in an anaerobic environment, when the wastewater in the membrane pool 1 gradually floods the membrane assembly 3, the membrane tube 302 in the membrane assembly 3 is a silicon carbide ceramic membrane, which is used for filtering solid substances in the wastewater, and allows water molecules to enter the membrane tube 302, in this process, the biogas generated in the anaerobic environment is separated by a biogas separation device to obtain hydrogen and carbon dioxide in a certain proportion and water is injected into the conduit 601, and under the action of the Venturi tube 602, nanobubbles are generated by hydraulic cavitation, so that the nanobubbles in the wastewater occur gas floatation to remove suspended solids in the wastewater, and the nanobubbles break under pressure to produce micro-jet and micro-vortex effects on the membrane tube 302, which can remove the coagulum adhered to the membrane tube 302, and can ensure the flux of the membrane tube 302 and the efficiency of the wastewater filtration, wherein the biogas separation device and the Venturi tube 602 are prior art, and the specific structure and working principle will not be described again, and the water production pump is used to extract the liquid in the membrane tube 302.

[0023] Example two In use, it is found that since the position of the membrane tube 302 in the wastewater does not change, the coagulum is easily adhered to the outer wall of the membrane tube 302, although the nanobubbles can clean the coagulum on the membrane tube 302 to some extent, but due to the fixed position of the membrane tube 302, the cleaning effect of the nanobubbles on the coagulum on the membrane tube 302 is poor, which easily affects the flux of the membrane tube 302 and reduces the efficiency of the wastewater filtration, therefore, based on the above embodiment, further improvement is made.

[0024] As shown in Figures 3 to 7 The adjusting assembly 4 includes two adjusting plates 401 located between the two groups of membrane assemblies 3 and slidingly connected with the support frame 2, the push rod 402 is fixed to one end of the support plate 301 close to the adjusting plate 401, and the guide plate 403 is fixed to one side of the adjusting plate 401 close to the support plate 301.

[0025] The flow sensor 304 is arranged on the support frame 2, which is used to detect the flow change in the membrane tube 302, when the flow is greater than the first flow threshold, the adjusting plate 401 does not slide, when the flow is between the first flow threshold and the second flow threshold, the adjusting plate 401 slides to drive the adjacent two support plates 301 to horizontally alternate reciprocating sliding through the push rod 402.

[0026] The end face of the adjusting plate 401 close to the support plate 301 is a wavy surface, and the free end of the push rod 402 is in contact with the wavy surface of the adjusting plate 401.

[0027] The support frame 2 is fixed with auxiliary plates 407 on both sides, the auxiliary plates 407 are provided with a plurality of sliding grooves 408 corresponding to the support plates 301, the sliding grooves 408 are slidably connected with connecting blocks 409, the support plates 301 are fixed with sliding rods 410 away from the adjusting plates 401, the sliding rods 410 are slidably connected with the connecting blocks 409 on the corresponding side, and the connecting blocks 409 are provided with elastic elements 411 connected with the sliding rods 410.

[0028] The support frame 2 is provided with a driving assembly 5 on one side of the adjusting plate 401, the driving assembly 5 comprises a fixed plate 501 fixedly connected with the support frame 2, the adjusting plate 401 is slidably connected with the fixed plate 501, the fixed plate 501 is provided with a waterproof box 502 away from the adjusting plate 401, the waterproof box 502 is provided with an electric push rod 503, an output end of the electric push rod 503 extends out of the waterproof box 502 and is fixed with a push plate 504, the push plate 504 is fixedly connected with the corresponding adjusting plate 401 at both ends, the electric push rod 503 is electrically connected with a flow sensor 304 through a control panel, and the flow sensor 304 is located on a water production pipe 305 and used for detecting the liquid flow in the water production pipe 305.

[0029] In use, when the flow sensor 304 detects that the liquid flow in the water production pipe 305 is greater than a first threshold value, the adjusting plate 401 is in a static state and the position of the membrane tube 302 is not changed, at this time, the flux of the membrane tube 302 is in a normal unblocked state, when the flow sensor 304 detects that the liquid flow in the water production pipe 305 is between the first threshold value and a second threshold value, at this time, the flow sensor 304 controls the electric push rod 503 to reciprocatingly stretch and shrink in a small amplitude through the control panel, so that the electric push rod 503 drives the adjusting plate 401 to slide along the fixed plate 501 through the push plate 504, and the adjusting plate 401 slides in a small amplitude, when one of the push rods 402 slides from the convex part to the concave part of the wave-shaped surface of the adjusting plate 401, at this time, the adjusting plate 401 no longer drives the push rod 402, and the elastic element 411 drives the support plate 301 to slide towards the adjusting plate 401 through the sliding rod 410 under the action of the elastic element 411, since the membrane tube 302 has a certain toughness and relaxation, the support plate 301 drives the membrane tube 302 to tilt and move towards the adjusting plate 401, At the same time, the adjacent push rod 402 slides from the recess to the protrusion of the adjusting plate 401, so that the push rod 402 drives the support plate 301 to slide away from the adjusting plate 401, the support plate 301 drives the sliding rod 410 to slide into the connecting block 409, the elastic member 411 is compressed, and the support plate 301 drives the membrane tube 302 to tilt and move away from the adjusting plate 401, so that the adjacent membrane tubes 302 move in different directions to disturb the wastewater and generate vortex, which cleans the solidified substances on the outer wall of the membrane tube 302, and further accelerates the breaking of the nano bubbles in the wastewater, improves the cleaning effect of the nano bubbles on the solidified substances on the outer wall of the membrane tube 302, and continuously reciprocatingly moves and offsets under the action of the adjusting plate 401, which improves the cleaning efficiency of the solidified substances on the outer wall of the membrane tube 302. When the flow sensor 304 detects that the flow in the water production pipe 305 is greater than the first threshold value, the flux of the membrane tube 302 returns to the normal range, so that the electric push rod 503 drives the adjusting plate 401 to return to the initial position through the push plate 504, so that the adjusting plate 401 drives the plurality of membrane tubes 302 to return to the initial state through the push rod 402 and the support plate 301.

[0030] In summary, through the cooperative arrangement of the adjusting plate 401 with a wave-shaped surface, the push rod 402, the support plate 301, the sliding rod 410, the elastic member 411 and the nano bubbles, not only can the adjacent two groups of membrane tubes 302 be driven to horizontally reciprocate and offset by the adjusting plate 401, the push rod 402 and the support plate 301, so that the membrane tube 302 disturbs the wastewater to a certain extent to generate vortex, which can not only clean the solidified substances on the surface of the membrane tube 302, but also press the nano bubbles to accelerate the breaking, so that the microjet generated after the breaking of the nano bubbles acts on the membrane tube 302, improves the cleaning efficiency of the solidified substances on the outer wall of the membrane tube 302, and effectively ensures that the flux of the membrane tube 302 is within the normal range, and improves the efficiency of wastewater treatment.

[0031] Example Three In the above use process, it is also found that due to the existence of a certain gap between each group of membrane tubes 302, the water flow disturbance generated by the horizontal reciprocating movement of the membrane tube 302 has low cleaning effect on the stubborn solidified substances on the outer wall of the membrane tube 302, which easily leads to continuous adhesion of solidified substances on the outer wall of the membrane tube 302, resulting in a large decrease in the flux of the membrane tube 302. Therefore, based on the above embodiment, further improvement is made.

[0032] As Figures 3 to 8As shown, the guide plate 403 is provided with a plurality of guide slots 404 corresponding to the support plates 301, the push rod 402 is fixed with a connecting plate 405, the free end of the connecting plate 405 is fixed with a telescopic rod 406 inserted into the corresponding guide slot 404, when the flow is less than the second flow threshold, the adjusting plate 401 slides and drives the adjacent two support plates 301 to vertically and alternately reciprocate, while the adjacent support plates 301 horizontally and alternately reciprocate.

[0033] The guide slot 404 is composed of two inclined slots 4041 and a horizontal slot 4042, and the two inclined slots 4041 form a V shape, and the openings of the V shapes of the two inclined slots 4041 in the adjacent two guide slots 404 are opposite.

[0034] The side of the guide plate 403 close to the support plate 301 is provided with a constraint plate 412 fixedly connected with the adjusting plate 401, the constraint plate 412 is provided with a constraint slot 413 consistent with the shape of the guide slot 404, and the output end of the telescopic rod 406 extends out of the corresponding constraint slot 413.

[0035] In use, when the flow sensor 304 detects that the liquid flow in the water production pipe 305 is less than the second threshold, at this time, the flow sensor 304 controls the electric push rod 503 to reciprocate greatly through the control panel, so that the electric push rod 503 drives the push plate 504 to slide the adjusting plate 401 along the fixed plate 501, and the adjusting plate 401 slides greatly, when one of the push rods 402 slides from the convex part to the concave part of the wave-shaped surface of the adjusting plate 401, and when the push rod 402 drives the telescopic rod 406 to slide along the horizontal slot 4042 of the guide slot 404 to the inclined slot 4041 through the connecting plate 405, the push rod 402 drives the telescopic rod 406 to extend or retract through the connecting plate 405, so that one of the telescopic rods 406 slides downward and then upward under the action of the inclined slot 4041, the telescopic rod 406 drives the push rod 402 to move downward and then upward through the connecting plate 405, the push rod 402 drives the membrane tube 302 to move downward and then upward through the support plate 301, and the support plate 301 drives the connecting block 409 to slide along the sliding groove 408 through the sliding rod 410, the constraint plate 412 and the constraint slot 413 are arranged to enable the fixed end of the telescopic rod 406 to be stably positioned in the guide slot 404, and the output end of the telescopic rod 406 can pass through the constraint slot 413.

[0036] At this time, the adjacent telescopic rods 406 first slide upward and then slide downward under the action of the chute 4041, the telescopic rods 406 drive the push rod 402 to first move upward and then move downward through the connecting plate 405, the push rod 402 drives the membrane tube 302 to first move upward and then move upward through the support plate 301, so that the adjacent two groups of membrane tubes 302 can reciprocatingly and alternately vertically move, one group of membrane tubes 302 gradually tightens downward, so that the wastewater can comprehensively clean the surface of the membrane tube 302, and the adjacent group of membrane tubes 302 gradually relaxes upward, the membrane tube 302 gradually bends to increase the area covered by the nano bubbles, so that the nano bubbles better act on the outer wall of the membrane tube 302 for cleaning, and at the same time, the distance between the adjacent two groups of membrane tubes 302 is reduced, and at the same time, under the action of the adjusting plate 401, the vertically and alternately sliding support plate 301 synchronously horizontally and alternately reciprocatingly slides under the action of the adjusting plate 401, at this time, the water flow disturbance generated by the horizontal movement of the membrane tube 302 can better act on the outer wall of the membrane tube 302, so as to comprehensively remove the stubborn solidified substances on the outer wall of the membrane tube 302, further ensure the flux of the membrane tube 302, and improve the efficiency and quality of the wastewater treatment, when the flow sensor 304 detects that the liquid flow in the water production pipe 305 is greater than the first threshold value, at this time, the water production flux of the membrane tube 302 returns to the normal range, at this time, the plurality of membrane tubes 302 can return to the initial state through the adjusting plate 401, the guide plate 403 and the guide groove 404.
