The first fixed guide vane 260 and the second fixed guide vane 270 are respectively arranged on both sides of the fixed guide seat 220. The microorganism implantation 240, the first fixed guide vane 260 and the second fixed guide vane 270 are all spiral-shaped. The surfaces of the first rotating seat 210 and the second rotating seat 230 are rotatably mounted with an eccentric wheel ring 250. One end of the microorganism implantation 240 is fixedly connected with a rotating wheel 241, and the rotating wheel 241 is rotatably sleeved on the inner side of the eccentric wheel ring 250.

[0034] A crankshaft rod 231 is fixedly connected to one side of the rotating wheel 241, and one end of the crankshaft rod 231 is drivingly connected to the output end of the driving motor 110. The center of the rotating wheel 241 deviates from the axis of the eccentric wheel ring 250. A plurality of densely distributed microporous centrifugal guide components 300 are provided on the surface of the microorganism implantation 240, including a pump box 310 and a centrifugal impeller 320 rotating inside the pump box 310. One end of the centrifugal impeller 320 is in sliding contact with the surface of the second rotating seat 230, and a liquid passage hole located at the axis of the microorganism implantation 240 is opened on the surface of the second rotating seat 230. A plurality of centrifugal flow channels 321 are arranged through the surface of the centrifugal impeller 320.

[0035] In this embodiment, the microbial degradation cylinder 200 is a cylindrical structure, and its two ends are fixedly connected and sealed to the ends of the driving bracket 100 and the centrifugal guide assembly 300 respectively, and the outer peripheries of the first rotating seat 210, the fixed guide seat 220 and the second rotating seat 230 are fixedly connected to the inner side of the driving bracket 100.

[0036] In this embodiment, the microbial bed 240 is constructed of zeolite material, and microbial communities for water pollution degradation treatment are attached to the surface of the microbial bed 240 and the inside of the micropores.

[0037] Specifically, the porous and loose structure of the zeolite structure is utilized to form an attachment bed structure for microorganisms to improve the attachment strength, and the surface micropores allow water and air to pass through.

[0038] In this embodiment, the lengths of the microbial bed 240, the first stator guide vane 260 and the second stator guide vane 270 are the same, the ends of the first stator guide vane 260 and the second stator guide vane 270 on both sides of the stator guide seat 220 are evenly slidably abutted against the surface of the stator guide seat 220, and the first stator guide vane 260 and the second stator guide vane 270 are respectively slidably abutted against the surfaces of the eccentric wheel ring 250 on both sides.

[0039] In this embodiment, the centers of both ends of the crankshaft rod 231 are coaxial with the center of the eccentric wheel ring 250, and an eccentric shaft located inside the microorganism implantation 240 is provided in the middle of the crankshaft rod 231, and the center of the eccentric shaft is coaxial with the center of the rotating wheel 241.

[0040] Specifically, the eccentric movement of the impeller 241 and the microorganism bed 240 is realized during the rotation of the crankshaft rod 231. This movement squeezes the water between the microorganism bed 240 and the first stator guide vane 260. Part of the water overflows through the micropores on the surface of the microorganism bed 240 under the positive pressure, so that the water is in full contact with the surface of the microorganism bed 240 and the microorganisms in the micropores.

[0041] In this embodiment, the water inlet groove 221 is located on the inner side of the fixed guide seat 220 and at the axis of the microorganism implantation bed 240 , and the other side flow channel outlet 222 is located on the outer periphery of the microorganism implantation bed 240 .

[0042] Specifically, water at the axis of the fixed guide seat 220 on one side is input through the water inlet groove 221 and discharged from the flow channel outlet 222 to the periphery of the zero-one microorganism implantation 240 for secondary microbial treatment.

[0043] In this embodiment, the crankshaft rod 231 passes through the impeller 241 and is connected to the centrifugal impeller 320 , and the centrifugal impeller 320 is coaxially arranged with the eccentric ring 250 .

[0044] Furthermore, the centrifugal flow channel 321 is evenly distributed in the circumferential direction, and a water inlet ring connected to the port of the centrifugal flow channel 321 is provided on one side of the centrifugal impeller 320, and the through hole groove on the surface of the second rotating seat 230 is sealingly engaged and slidably abutted with the surface water inlet ring of the centrifugal impeller 320.

[0045] Specifically, when the microorganism implantation 240 rotates the crankshaft 231, the centrifugal impeller 320 inside the centrifugal guide assembly 300 is synchronously driven to rotate to centrifugally discharge the water. A negative pressure effect is formed at the axis of the microorganism implantation 240 and the second stator guide vane 270. The water passes through the through hole groove and the water inlet ring, thereby increasing the flow rate of the water inside the microbial degradation cylinder 200.

[0046] The working principle and use process of the present invention:

[0047] In the use of the sewage treatment device, water is introduced into the interior of the microbial degradation cylinder 200 through the liquid inlet 120. The water inlet amount is adjusted according to the water level inside the liquid inlet 120 so that the water level is continuously lower than the surface of the microbial implantation 240. Driven by the drive motor 110, the two microbial implantation 240 respectively move in the compartments formed on both sides of the fixed guide seat 220. Under the eccentric rotation of the crankshaft rod 231 and the guiding movement of the runner 241 and the eccentric wheel ring 250, the water in the compartment moves between the microbial implantation 240 and the first microbial implantation 240. Under the guiding action of the fixed guide vane 260, the water gradually enters the center of the first fixed guide vane 260, and the water between the microorganism implantation 240 and the first fixed guide vane 260 is squeezed by the movement. Part of the water overflows through the micropores on the surface of the microorganism implantation 240 under the positive pressure, so that the water is fully in contact with the surface of the microorganism implantation 240 and the microorganisms in the micropores. In this process, the water and the gas entering the microorganism implantation 240 pass through the micropores on the surface of the microorganism implantation 240, forming an aeration effect, thereby increasing the dissolved oxygen content of the water body.

[0048] The water on one side of the fixed guide seat 220 flows into the other side of the microbial degradation cylinder 200 through the water inlet groove 221 and the flow channel outlet 222. Under the action of the microbial implantation 240 and the second fixed guide vane 270 on this side, microbial contact reaction and water aeration are further carried out. The microbial implantation 240 rotates and synchronously drives the centrifugal impeller 320 inside the centrifugal guide assembly 300 to rotate to centrifugally discharge the water, reduce the pressure effect at the axis of the microbial implantation 240 and the second fixed guide vane 270, and increase the flow rate of the water inside the microbial degradation cylinder 200. The water after microbial degradation is discharged through the centrifugal flow channel 321.
