The unit groups are equipped with assembly components, which can be used to assemble the first unit 13, the second unit 14, the third unit 15, and the fourth unit 16. The problem of transportation by freight can be solved by hoisting and transporting each unit separately and assembling it on site. Each unit is small in size and light in weight, saving costs during hoisting. The corrugated plate 12 has greater rigidity and the structure is more robust and durable. At the same time, the frame structure replaces the grid rib structure, which greatly reduces the workload of material cutting, welding and other processes during processing. The installation frame 10 also has better structural stability.

[0025] Reference Figure 1 In a preferred embodiment, an assembly component is provided, comprising wire rope cables 17 and tie rods 18. The wire rope cables 17 are connected to the first unit 13, the second unit 14, the third unit 15, and the fourth unit 16, respectively.

The settled clear water can be discharged into the clear water tank 8, and after meeting the discharge requirements, it can be discharged through the clear water outlet 9.

[0027] Reference Figures 1-3 In a preferred embodiment, an aerobic tank 4 is installed on the front side of the inner wall of the mounting frame 10. The back of the aerobic tank 4 is connected to an anoxic tank 3, and the left side of the anoxic tank 3 is connected to an anaerobic tank 2. The surface of the anaerobic tank 2 is connected to a sewage inlet 1, through which sewage can be transported to the aerobic tank 4. In this way, anaerobic microorganisms can be used in the aerobic tank 4 to decompose the organic matter in the sewage. The sewage containing anaerobic microorganisms is then discharged into the anaerobic tank 2, where anaerobic microorganisms can decompose the organic matter in the sewage. The anoxic tank 3 mainly utilizes bacteria to achieve sewage denitrification and adjust the pH value of the sewage. In addition, the fourth unit 16 includes a secondary sedimentation tank 5, which is connected to a stirring tank 6. The secondary sedimentation tank 5 can use a physical method of sedimentation to remove sediments in the sewage, which can settle impurities decomposed by microorganisms.

The length of the steel wire ropes 17 can be adjusted by tightening the steel wire rope buckles 19, thereby adjusting the prestress. During sewage treatment, the sewage is discharged from the sewage inlet into the anaerobic tank 2. Anaerobic microorganisms are added to the anaerobic tank 2 to promote anaerobic microbial growth. The wastewater is thoroughly mixed with anaerobic microorganisms and then discharged into anoxic tank 3. In anoxic tank 3, bacteria are used to denitrify the wastewater and adjust its pH value. The wastewater is then discharged into aerobic tank 4, where anaerobic microorganisms decompose the organic matter in the wastewater. The wastewater is then discharged into secondary sedimentation tank 5 for sedimentation. Next, the wastewater is discharged into mixing tank 6 where chemical agents are added. After being discharged into final sedimentation tank 7, the wastewater is treated by flocculation and sedimentation under the action of chemical agents. The clear water is then discharged into clear water tank 8 and then discharged from clear water outlet 9.
