[0018] The technical effects and advantages of the present invention: 1. In the present invention, a diversion groove with a stepped structure is provided on the surface of the treatment tank. During the treatment process of sewage, the sewage can flow along the diversion groove. A filtering part is arranged at the stepped structure of the diversion groove, and a biofilm is arranged inside the filtering part. When the sewage flows along the diversion groove, it can enter the filtering part and pass through the biofilm. The biofilm can decompose the organic matter in the sewage. A circulation pipe is arranged outside the treatment tank, and the circulation pipe can pump the sewage inside the treatment tank to the top of the diversion groove to realize the circulation of the sewage. During the circulation process, the sewage can be in full contact with the air to achieve the effect of aeration.

[0019] 2. In the present invention, a pressurizing pipe is provided above the treatment tank. A water guide cover is arranged at the bottom end of the pressurizing pipe, and a water outlet pipe is arranged outside the water guide cover. An air inlet nozzle is arranged inside the water outlet pipe. When the sewage circulates under the guidance of the circulation pipe, the sewage passes through the pressurizing pipe, the water guide cover and the water outlet pipe in sequence. When the sewage passes through the water outlet pipe, the flow rate of the sewage inside the water outlet pipe is relatively fast. At this time, the water outlet pipe and the air inlet nozzle draw in the outside air under the Venturi effect and inject it into the sewage to achieve the purpose of improving the aeration effect of the sewage, thereby improving the decomposition efficiency of the organic matter in the sewage.

[0020] 3. In the present invention, through the cooperation of multiple components such as biofilms, frames and connecting rods, when there are too many impurities on the biofilm, the electric telescopic part reciprocates, thereby driving the slider and the connecting rod to move. During the movement of the connecting rod, it drives the frame to change the angle relative to the bottom surface of the diversion groove, and uses the downward flowing impact generated by the sewage overflowing from the transition groove to wash the impurities on the surface of the biofilm, thereby improving the filtering effect of the biofilm.

[0021] 4. In the present invention, through the cooperation of components such as a rotating plate, a top plate and an electromagnetic part, it is convenient to clean the dirt on the surface of the biofilm. By controlling the electromagnetic part to generate reciprocating adsorption and repulsion on the permanent magnetic part on the rotating plate, the rotating plate is driven to rotate. During the rotation of the rotating plate, it drives the top plate to vibrate the adjacent ends of two adjacent biofilms and vibrate and clean the dirt at one end of the biofilm, thereby improving the cleaning effect of the biofilm. At the same time, during the rotation of the rotating plate, it pushes the push plate, so that the push plate squeezes the water flow in the water spraying tank. The water subjected to the extrusion sprays out through the spray holes and cleans the surface of the biofilm, thereby improving the filtering effect of the biofilm.

[0022] 5. Through the cooperation of components such as the rotating plate, top plate, and electromagnetic part, the present invention facilitates the extrusion of moisture in the biofilm when replacing the biofilm, preventing the contamination of other areas. The electromagnetic part attracts the rotating plate, causing the rotating plate to drive the top plate to squeeze one end of the biofilm during rotation. By controlling the repulsive force generated by adjacent electromagnetic parts on the rotating plate, the rotating plate drives the top plate to squeeze the other end of the biofilm during rotation. At the same time, the top plate of the biofilm squeezes both sides of the biofilm, facilitating the extrusion of moisture in the biofilm by the top plates on both sides when extracting the biofilm, preventing the contamination of other areas due to excessive moisture on the biofilm when removing the biofilm, and also facilitating the subsequent treatment of the removed biofilm.

When the push plate 513 is no longer pushed, the reset member 515 starts to reset and push the push plate 513 to reset, generating suction in the water spraying tank 512, and sucking the water in the external water tank into the interior of the water spraying tank 512 through the pipeline and the one-way valve; the push plate 513 is slidably arranged inside the corresponding water spraying tank 512; the reset members 515 are provided in multiple groups and are fixedly arranged between the corresponding push plates 513 and the water spraying tanks 512; the electromagnetic parts 516, which are electrically connected to the control system, are provided in multiple groups and are all fixedly arranged on the tops of the water spraying tanks 512. Through the cooperation of the electromagnetic parts 516 and the permanent magnetic parts, the rotating plates 510 and the top plates 511 can be flipped so as to achieve the squeezing of the biofilm 503 by the top plates 511.

[0046] It should be noted that the number of biofilms 503 can be set according to requirements, and the corresponding components will increase or decrease accordingly.

[0047] A circulation part, which is used to transport the sewage in the treatment tank 1 to the transition tank 3 for re - filtration; a circulation pipe 6, which is located outside the treatment tank 1 and is connected to the cavity inside the treatment tank 1. The circulation pipe 6 can extract and transport the sewage inside the treatment tank 1 to the uppermost end of the diversion tank 2. A pressurizing pipe 61, which is located above the top of the transition tank 3 and is connected to the top of the circulation pipe 6, is used for discharging the sewage.

[0048] A water guiding cover 62, which is located at the bottom end of the pressurizing pipe 61 and above the top of the transition tank 3.

[0049] A water outlet pipe 63, which is located at the tangent of the outer side wall of the water guiding cover 62, and the height of the water outlet pipe 63 is lower than the overflow weir 31. The overflow weir 31 can block the sewage ejected from the water outlet pipe 63 to avoid sewage splashing; through the cooperation of the water guiding cover 62 and the water outlet pipe 63, it is used to guide the discharge of sewage.

[0050] An air inlet nozzle 64, which is located inside the water outlet pipe 63 and is aligned with the outlet direction of the water outlet pipe 63. The air inlet nozzle 64 and the water outlet pipe 63 extract external air through the Venturi principle and inject it into the sewage for aeration.

[0051] A spiral plate 621, which is used to increase the flow rate of sewage. It is located inside the pressure pipe 61 and can rotate inside the pressure pipe 61. A driving motor 622, which is electrically connected to the control system. It is located at the top of the pressure pipe 61 and is drivingly connected to the top of the spiral plate 621. The driving motor 622 is used to drive the spiral plate 621 to rotate.

[0052] A flow guiding block 623, which is located at the bottom end of the pressure pipe 61 and is provided with a hemispherical structure. The flow guiding block 623 is used to guide the sewage discharged from the pressure pipe 61 to be evenly dispersed.

[0053] An air inlet pipe 641, which is located at one end of the air inlet nozzle 64, and the top end of the air inlet pipe 641 extends to the outside of the pressure pipe 61. The air inlet pipe 641 is used to extract external air, and it can extend to the outside of the chassis 8.

[0054] A circulation pump 65 is provided in the middle of the circulation pipe 6. The circulation pump 65 can realize the extraction and transportation of sewage.

[0055] When using the sewage treatment device for decomposing organic matter of this embodiment, sewage can enter the cavity inside the treatment tank 1 through the guidance of the pipeline. The circulation pipe 6 can extract the sewage inside the treatment tank 1 under the action of the circulation pump 65 and transport it to the top end of the diversion trough 2 through the circulation pipe 6, the pressure pipe 61, the water guide cover 62, the water outlet pipe 63 and the transition trough 3. The sewage can flow along the stepped diversion trough 2 and fill the multiple transition troughs 3. With continuous injection, the sewage in the transition trough 3 overflows. The overflowing sewage flows out through the overflow trough 32. The sewage overflowing through the overflow trough 32 can enter the filtering part 5. At this time, there is a gap between adjacent biofilms 503. The sewage contacts with the adjacent biofilms 503 when passing through this gap. The biofilm 503 can decompose and adsorb the organic matter in the sewage to achieve the effect of sewage treatment. The treated sewage can flow along the diversion trough 2 to the through groove 4 and then flow back into the treatment tank 1 to realize the cyclic treatment of sewage, thereby ensuring the sewage treatment effect.

[0056] During the process of the sewage circulating through the circulation pipe 6, the sewage enters the pressurizing pipe 61 through the circulation pipe 6. At this time, the driving motor 622 drives the spiral plate 621 to move. The spiral plate 621 can transport the sewage in the upper part of the pressurizing pipe 61 downward to achieve the effect of increasing the speed of the sewage. Then the sewage enters the water guide cover 62 after passing through the pressurizing pipe 61 and is discharged through the water outlet pipe 63 outside the water guide cover 62. At this time, the flow velocity of the sewage inside the water outlet pipe 63 is greater than the flow velocity of the outside air. At this time, the air inlet nozzle 64 inside the water outlet pipe 63 extracts the outside air through the air inlet pipe 641 under the Venturi effect and injects the air into the sewage to achieve the aeration effect of the sewage, so as to provide an environment such as oxygen for the biofilm 503 to decompose and adsorb the organic matter in the sewage, so as to achieve the purpose of improving the sewage treatment efficiency.

[0057] When the biofilm 503 is in long-term use, due to the continuous attachment of other impurities such as microorganisms in the sewage, the thickness of the biofilm 503 increases, affecting the filtration effect. At this time, by controlling the electric telescopic member 505 to drive the slider 506 to move, the slider 506 pushes the connecting rod 504 during the movement process, so that the connecting rod 504 can move along the chute 507 during the pushing process. At this time, the pushed connecting rod 504 drives multiple groups of frames 502 and the biofilm 503 to be inclined relative to the bottom surface of the diversion groove 2, that is, to move from the initial state to the second position, as Figure 8 and Figure 9 shown. The above process is reciprocally operated so that the water flowing out of the transition tank 3 can wash the impurities and dirt on the biofilm 503, thereby improving the filtration effect of the biofilm 503.

[0058] When there is too much dirt attached to the biofilm 503, by starting the electromagnetic part 516, using the adsorption and repulsion of the electromagnetic part 516, controlling the rotating plate 510 to rotate around the groove 509, and during the rotation of the rotating plate 510, driving the top plate 511 to reciprocally vibrate the adjacent two biofilms 503, and vibrating and cleaning the dirt or impurities on the biofilm 503 through the reciprocal vibration.

[0059] While the rotating plate 510 rotates around the groove 509, the rotating plate 510 generates a thrust on the push plate 513. The push plate 513 under the thrust moves in the water spray tank 512 and squeezes the water and the reset member 515 in the water spray tank 512. The squeezed water is sprayed onto the biofilm 503 through the spray holes. The water sprayed onto the biofilm 503, on the one hand, the sprayed water can wash and clean the dirt that falls on the biofilm 503 or the side wall of the frame 502 during the vibration cleaning, and on the other hand, the water flow sprayed from the water spray tank 512 can cooperate with the vibration cleaning to strengthen the cleaning of the biofilm 503, thereby improving the filtration effect of the biofilm 503.

[0060] When the biofilm 503 needs to be replaced according to the usage requirements, one of the electromagnetic parts 516 is turned on, so that the electromagnetic part 516 attracts the rotating plate 510. The attracted rotating plate 510 drives the top plate 511 to squeeze against one side wall of the biofilm 503 during rotation. At the same time, the adjacent electromagnetic part 516 is turned on to repel the rotating plate 510, and the repelled rotating plate 510 drives the top plate 511 to squeeze against the other side wall of the biofilm 503 during rotation. As Figure 10 shown, it is convenient to squeeze the internal moisture when removing the biofilm 503, prevent the moisture on the biofilm 503 from contaminating other areas when the biofilm 503 is taken out, and at the same time facilitate the subsequent treatment of the removed biofilm 503; at the same time, when other biofilms 503 are taken out, the above operations are also carried out.

[0061] When the rotating plate 510 drives the top plate 511 to squeeze against the other side wall of the biofilm 503 during rotation, the bottom of the rotating plate 510 pushes the push plate 513. The pushed push plate 513 moves in the water spraying tank 512 and squeezes the water and the reset part 515 in the water spraying tank 512. The squeezed water is sprayed onto the biofilm 503 through the spray holes to remove the impurities on the biofilm 503.

[0062] Through the cooperation of multiple components such as the biofilm 503, the frame body 502, and the connecting rod 504, when there are too many impurities on the biofilm 503, the electric telescopic part 505 reciprocates, thereby driving the slider 506 and the connecting rod 504 to move. During the movement of the connecting rod 504, the frame body 502 is driven to change the angle relative to the bottom surface of the diversion groove 2, and the impurities on the surface of the biofilm 503 are washed by the downward flowing impact generated by the sewage overflowing from the transition groove 3, thereby improving the filtering effect of the biofilm 503.

[0063] Through the cooperation of components such as the rotating plate 510, the top plate 511, and the electromagnetic part 516, it is convenient to clean the dirt on the surface of the biofilm 503. By controlling the electromagnetic part 516 to generate reciprocating adsorption and repulsion on the permanent magnetic part on the rotating plate 510, the rotating plate 510 is driven to rotate. During the rotation of the rotating plate 510, the top plate 511 is driven to vibrate the adjacent ends of two adjacent biofilms 503 and vibrate and clean the dirt at one end of the biofilm 503, thereby improving the cleaning effect of the biofilm 503. At the same time, during the rotation of the rotating plate 510, the push plate 513 is pushed, so that the push plate 513 squeezes the water flow in the water spraying tank 512. The squeezed water is sprayed out through the spray holes and cleans the surface of the biofilm 503, thereby improving the filtering effect of the biofilm 503.

[0064] Through the cooperation of components such as the rotating plate 510, the top plate 511, and the electromagnetic part 516, it is convenient to squeeze the moisture in the biofilm 503 when replacing the biofilm 503, preventing the pollution of other areas. The electromagnetic part 516 attracts the rotating plate 510, causing the rotating plate 510 to drive the top plate 511 to squeeze one end of the biofilm 503 when rotating. By controlling the adjacent electromagnetic parts 516 to repel the rotating plate 510, the rotating plate 510 drives the top plate 511 to squeeze the other end of the biofilm 503 when rotating. At the same time, the top plate 511 of the biofilm 503 squeezes both sides of the biofilm 503, facilitating the squeezing of the moisture in the biofilm 503 by the top plates 511 on both sides when extracting the biofilm 503, preventing the biofilm 503 from polluting other areas due to excessive moisture when the biofilm 503 is taken out, and also facilitating the subsequent treatment of the taken-out biofilm 503.
