The stepped ring packing 3 has the characteristics of large flux and low resistance, and the stepped ring has a smaller height-to-diameter ratio, so that the gas and liquid can be distributed more evenly;

[0036] After the sewage is diverted, more microorganisms can quickly attach to the stepped ring filler 3.

[0037] Soft fiber filler 2 is crafted to mimic the shape of natural aquatic plants. Made from aldehyde-treated polyester, the fiber or polyester yarn is attached to a central rope through a process of drawing and woolening. Soft fiber filler 2 has a large specific surface area and good elasticity, allowing for easy biofilm formation and removal.

[0046] The working principle of the present invention is as follows: when in use, sewage first enters the bottom shell 4 in the sewage treatment tank 8 through the water inlet pipe 9; as the water level continues to rise, the sewage will flow upward through multiple step ring fillers 3. The step ring fillers 3 have the characteristics of large flux and small resistance, and the step ring has a smaller height-to-diameter ratio, so that the gas and liquid can be distributed more evenly; after the sewage is diverted, more microorganisms can quickly attach to the step ring fillers 3.

[0047] Soft fiber filler 2 is crafted to mimic the shape of natural aquatic plants. Made from aldehyde-treated polyester, the fiber or polyester yarn is attached to a central rope through a process of drawing and woolening. Soft fiber filler 2 has a large specific surface area and good elasticity, allowing for easy biofilm formation and removal. It offers advantages such as a large specific surface area, rapid biofilm formation, and excellent treatment results.

[0048] Moreover, the soft fiber filler 2 and the stepped ring filler 3 are installed in a straight-up and straight-down manner, and the water flow direction rises vertically along the soft fiber filler 2, which effectively solves the problem of traditional water flow horizontally impacting the soft fiber filler 2 and causing breakage, and also avoids the problem of the soft fiber fillers 2 being entangled with each other.

[0049] When a certain soft fiber filler 2 needs to be replaced, the hook is directly removed from the crossbar 5, and then the bottom hook is also removed from the stepped ring filler 3, so that the effect of separate removal and replacement can be achieved.
