[0002] At present, with the continuous acceleration of economic development in large, medium and small cities and towns, the amount of water required to be treated by various sewage treatment plants and stations in my country is constantly increasing. Coupled with the continuous improvement of requirements for effluent water quality, most of the early sewage treatment plants and stations are faced with the task of upgrading and transformation.

[0003] Existing suspended biological fillers can generally be directly placed inside the sewage treatment pool. They have the characteristics of a suspended full three-dimensional structure, a large specific surface area, no need for fixation, easy biofilm formation, and no clogging. If suspended biological fillers are needed in conventional renovation projects, it is necessary to add iron meshes and other devices to the water holes between the pool walls in advance to prevent the fillers from leaking. The inventor believes that the iron mesh currently used to prevent the fillers from leaking is inconvenient to install on the pool wall of the sewage treatment pool. Summary of the invention

[0035] Reference Figure 1 and Figure 2 The suspended biological filler device 1 includes a mounting plate 11, a guide rail 12, a lower panel 13, a quick connector 14, a side elevation module 15 and a traction member 16. The lower panel 13 is a mesh structure. The lower panel 13 is horizontally arranged inside the sewage treatment tank 2. The four top corners of the lower panel 13 are provided with embedding grooves 131. There are four guide rails 12, and the four guide rails 12 are respectively vertically arranged inside the four embedding grooves 131 of the lower panel 13. The mounting plate 11 is horizontally arranged on one side of the guide rail 12 close to the side wall of the sewage treatment tank 2 and is aligned with the upper end surface of the sewage treatment tank 2. The mounting plate 11 is detachably mounted on the side wall of the sewage treatment tank 2 by means of fixing bolts 17; the quick connector 14 is arranged between the guide rail 12 and the lower panel 13 and keeps the positions of the two relatively fixed; two groups of side facade modules 15 are arranged in total, and the two groups of side facade modules 15 are arranged in sequence along the length direction of the sewage treatment tank 2; the side facade modules 15 are arranged between the two guide rails 12 and are detachably connected to the two guide rails 12; the traction member 16 is arranged on the sewage treatment tank 2 and can drive the guide rail 12 to move upward or downward inside the sewage treatment tank 2.

[0036] Before adding the suspended biological filler 3 into the sewage treatment tank 2, the four guide rails 12 are first moved to the four embedding grooves 131 of the lower panel 13, and the two are fixed together using the quick connector 14; then, the guide rails 12 and the lower panel 13 are lowered into the sewage treatment tank 2 by the traction member 16, and then two sets of side facade modules 15 are installed in sequence along the length direction of the sewage treatment tank 2.
