[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1-5 The diagram shows a mirror-like contaminant cleaning and collection mechanism for a wastewater treatment bioreactor. It includes a wastewater treatment reactor body 1, with first dividing plates 7 on both inner walls of the body 1. A movable plate 5 connects the two dividing plates 7. A biofilm assembly 8 is located inside the wastewater treatment reactor body 1, below the first dividing plates 7. A first gear 2 is located inside the front side wall of the wastewater treatment reactor body 1 and connected to the top cover. The first gear 2 meshes with a first rack 4 located inside the front side wall of the wastewater treatment reactor body 1. A second gear 3 also meshes with the first rack 4. A connecting plate 12 is fixedly connected to the movable plate 5. A second rack 13 is fixedly connected to the end of the connecting plate 12. A third gear 14 meshes with the second rack 13. The second gear 3 and the third gear 14 are connected by a connecting rod. Both the first rack 4 and the second rack 13 are located inside the side wall of the wastewater treatment reactor body 1, and clearances for their movement are reserved in the side wall.

[0027] The sewage treatment reactor body 1 is fixedly connected with a floating ball 11 at the lower end of the top cover, and an air inlet pipe 10 is connected to one side wall of the sewage treatment reactor body 1 and penetrates through the side wall of the sewage treatment reactor body 1 and is located below the biological reaction membrane assembly 8. When sewage enters, large garbage and suspended solids in the sewage fall on the filter screen 6, and the preliminarily filtered sewage flows into the sewage preliminary filtration treatment layer. When the sewage in the layer gradually accumulates, the floating ball 11 floats on the sewage and gradually lifts the top cover. With the overturning of the top cover, the first gear 2 connected with the rotating shaft rotates, drives the first rack 4 engaged therewith to move upward, and further drives the second gear 3 to rotate. The second gear 3 drives the third gear 14 to rotate, and the second rack 13 moves with the rotation of the third gear 14, and further moves the moving plate 5 into the hollow of the first partition plate 7 on the right side.

[0028] The biological reaction membrane assembly 8 comprises a biological reaction membrane, a plurality of air holes are formed in the biological reaction membrane, and a water baffle is arranged outside the biological reaction membrane. The oxygen introduced through the air inlet pipe 10 passes through the air holes and reaches the biological reaction membrane, so that the microorganisms on the biological reaction membrane can better oxidize and improve the cleaning efficiency.

[0029] The biological reaction membrane assembly 8 is connected with a transverse sliding rod 9 at the lower end, the end of the transverse sliding rod 9 is connected with a sliding rail, the sliding rail is located in the inner wall of the rear side of the sewage treatment reactor body 1, and the end of the sliding rail is further connected with a driving motor. The transverse sliding rod 9 is provided with a sewage cleaning brush, and the transverse sliding rod 9 slides in the sliding rail under the driving of the driving motor to clean the impurities on the water baffle outside the biological reaction membrane.

[0030] Holes are arranged in the middle of the two first partition plates 7, and the two ends of the moving plate 5 are located in the holes of the two first partition plates 7. When the moving plate 5 moves into the hole, the preliminarily filtered sewage can enter the membrane unit decontamination layer in the lower layer from the sewage preliminary filtration treatment layer.

[0031] The second rack 13 is located in the rear side wall of the sewage treatment reactor body 1, and a groove is formed in the rear side wall of the sewage treatment reactor body 1. The second rack 13 can move in the groove, and the second rack 13 moves with the rotation of the third gear 14 and further drives the engaged second rack 13 to move, so that the moving plate 5 moves into the hollow of the first partition plate 7 on the right side, and the preliminarily filtered sewage enters the membrane unit decontamination layer in the lower layer.

[0032] The floating ball 11 is located at the center position of the lower end of the top cover of the sewage treatment reactor body 1, and the floating ball 11 is made of corrosion-resistant floating material. The floating ball 11 is prevented from being damaged under the soaking of the sewage and causing the top cover to be unable to be lifted.

[0033] The working principle of this device is as follows: Wastewater is introduced into the main body 1 of the wastewater treatment reactor. Large particles, suspended solids, and other larger waste materials in the wastewater fall onto the filter screen 6. After preliminary filtration, the wastewater flows into the preliminary filtration treatment layer. As wastewater gradually accumulates in this layer, the float 11 floats on top, gradually lifting the top cover. As the top cover flips, the first gear 2 connected to its rotating shaft rotates, driving the first rack 4 meshing with it to move upward, which in turn drives the second gear 3 to rotate. The rotation of the second gear 3 drives the third gear 14 to rotate, and the second rack 13 moves with the rotation of the third gear 14. This causes the moving plate 5 to move into the hollow space inside the first partition plate 7 on the right. At this time, the sewage enters the decontamination layer of the lower membrane unit and undergoes a biological reaction with the bioreactor membrane assembly 8. Oxygen is introduced through the air inlet pipe 10 to increase the contact area between the microorganisms and oxygen in the bioreactor membrane, thereby improving the efficiency of sewage purification and completing the purification of sewage. When the sewage treatment reactor has been used for a long time, the baffle plate and other materials outside the bioreactor membrane assembly 8 become full of impurities. At this time, the drive motor starts, and the transverse sliding rod 9 slides along the sliding track under the drive of the drive motor to clean the impurities on the baffle plate outside the bioreactor membrane and keep it clean.

[0034] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
