There are four timing pulleys 10 dynamically connected, and the surfaces of the timing pulleys 10 on the upper and lower sides are sleeved with timing belts 11, which are meshed with the timing belts 11, and positioning plates 12 are fixed to the surfaces of the front and rear sides of the timing belts 11. An exhaust pipe 13 is connected to the right side of the top of the purification tank body 1, an air inlet pipe 14 is provided on the right side of the purification tank body 1, and the left side of the air inlet pipe 14 passes through the interior of the purification tank body 1, and a plurality of aeration plates 15 are provided at the lower part of the interior of the purification tank body 1, and the aeration plates 15 are connected to the air inlet pipe 14, and fixing plates 16 are embedded at the upper and lower parts of the front surface of the purification tank body 1.

[0028] A number of holes are provided on the surfaces of the upper and lower sides of the storage bag 6. The purification filler 7 is a BioFilter nanoporous bio-enzyme filler. After the domestic sewage is discharged through the drainage hole 5, the sewage can directly contact the purification filler 7 through the holes on the surface of the storage bag 6. The surface of the filler is attached with bio-enzymes, which can catalyze the decomposition of organic matter in the sewage and improve the treatment efficiency. The porous structure allows the filler to accommodate more microorganisms, forming a rich biofilm, further enhancing the sewage treatment capacity.

[0029] The water distribution pipe 3 is arranged in a square shape as a whole, and there are a plurality of drainage holes 5, which are evenly distributed on the inner surface of the water distribution pipe 3. Through the arrangement of the water distribution pipe 3 and the drainage holes 5, the discharged sewage can be evenly distributed above the storage bag 6 below, thereby improving the treatment effect of the sewage, so that the sewage can be evenly contacted with the purification filler 7.

[0030] The driving structure 9 includes a motor 91, a rotating rod 92, a first bevel gear 93, a connecting shaft 94 and a second bevel gear 95. The motor 91 is fixed to the front side of the installation box 8, the rotating rod 92 is rotatably connected to the inside of the installation box 8, and the output shaft of the motor 91 is fixedly connected to the front end of the rotating rod 92. The first bevel gear 93 is fixed to the front and rear sides of the surface of the rotating rod 92, the connecting shaft 94 is fixed to the surface of one side of the timing pulley 10 below, and one end of the connecting shaft 94 passes through the inside of the installation box 8 and is rotatably connected to the installation box 8. The second bevel gear 95 is fixed At the end of the connecting shaft 94 away from the timing pulley 10, the second bevel gear 95 is meshed with the first bevel gear 93. When the motors 91 on both sides are turned on, the output shaft of the motor 91 will drive the rotating rod 92 to rotate, thereby rotating the first bevel gear 93 on the surface of the rotating rod 92. Since the first bevel gear 93 is meshed with the second bevel gear 95, the connecting shafts 94 on the front and rear sides will rotate, and the connecting shafts 94 will drive the timing pulleys 10 on the lower sides to rotate, so as to adjust the position of the storage bag 6 inside the purification tank body 1.

[0031] There are several positioning plates 12, and the positioning plates 12 are used in pairs. The storage bag 6 is located between the positioning plates 12. Several flexible protrusions 19 are bonded to the surfaces of the positioning plates 12 facing each other, and the material of the flexible protrusions 19 is wear-resistant rubber. The positioning plates 12 can be arranged to locate the positions of multiple storage bags 6 inside the purification tank body 1, and the storage bags 6 are arranged from top to bottom. The flexible protrusions 19 can further improve the positioning effect of the storage bag 6 and prevent the storage bag 6 from moving inside the purification tank body 1, so that the purification filler 7 inside the storage bag 6 can purify the sewage.

[0032] A shielding cover is installed on the top of the exhaust pipe 13. The discharge height at the top of the exhaust pipe 13 is higher than the air intake height at the top of the air inlet pipe 14. The air inlet pipe 14 is arranged in an L shape as a whole, and a vertical axis fan 18 is installed on the surface of the air inlet of the air inlet pipe 14. When the height of the air inlet is lower than the air outlet, a natural air flow circulation can be formed, which can avoid the upward airflow when the air is taken in, reduce the possibility of reverse airflow and disturbance of the air flow at the exhaust port, thereby improving the ventilation efficiency. Moreover, the installation of the vertical axis fan 18 can further enhance the ventilation effect, so that the aeration plate 15 can oxygenate the interior of the purification tank body 1 to provide sufficient oxygen for microorganisms to degrade the target pollutants.

[0033] A disassembly rack 17 is fixed on both the left and right sides of the back of the fixed plate 16, and the disassembly rack 17 is L-shaped as a whole. A plurality of fixed grooves 20 are provided on the surface of the disassembly rack 17 on the upper part of the purification tank body 1, and a grid is fixed inside the fixed groove 20. When the upper fixed plate 16 is pulled out, the disassembly rack 17 on both sides of the back of the upper fixed plate 16 will hook out the top storage bag 6, and the disassembly rack 17 on the back of the lower fixed plate 16 can lift and support the bottom storage bag 6. The fixed grooves 20 on the surface of the upper disassembly rack 17 can facilitate the contact between the sewage and the purification filler 7 inside the lower storage bag 6, thereby avoiding the disassembly racks 17 on both sides of the upper side from blocking the holes on the surface of the storage bag 6.

[0034] Working principle: When the purification tank is in use, domestic sewage enters the water distribution pipe 3 through the control valve 4. At this time, the drainage hole 5 on the inner surface of the water distribution pipe 3 discharges the sewage. After the sewage flows down, it will directly contact the uppermost storage bag 6 below. The purification filler 7 inside the storage bag 6 will purify the sewage. The biological enzyme attached to the surface of the filler catalyzes the decomposition of organic matter in the sewage, and removes organic matter, nitrogen and phosphorus pollutants in the sewage. The sewage is effectively treated from top to bottom through the multiple layers of storage bags 6. The vertical axis fan 18 on one side is driven by natural wind force, so that the outside air enters the interior of the air inlet pipe 14, and the aeration plate 15 injects air into the purification tank body 1 to oxygenate the interior of the purification tank body 1. Finally, the gas is discharged through the exhaust pipe 13. After a period of use, when the work When personnel need to replace the purification filler 7 inside the top storage bag 6, the staff can remove the upper fixing plate 16, so that the upper disassembly and assembly rack 17 can hook out the top storage bag 6, and then the staff turns on the motors 91 on both sides, so that the timing pulleys 10 at the bottom of the left and right sides inside the purification tank body 1 rotate, so that the timing belt 11 moves, and the timing belt 11 drives the positioning plate 12 to move, so that all the storage bags 6 inside the purification tank body 1 move up as a whole, and then the staff removes the lower fixing plate 16, and the staff places the storage bag 6 with new purification filler 7 on the disassembly and assembly rack 17 on the surface of the lower fixing plate 16, and then the staff can reinstall the fixing plate 16 back to the surface of the purification tank body 1 to complete the filler replacement operation.
