[0002] With the acceleration of industrialization and the continuous growth of population, water pollution is becoming more and more serious, and the requirements for sewage treatment technology are becoming higher and higher. Moving bed biofilm reactor (MBBR), as a new type of biofilm sewage treatment technology, came into being in this context. This technology was developed by researchers in the late 1980s on the basis of biological contact oxidation and biological fluidized bed, by absorbing the advantages of both and combining the research results of modern biotechnology and materials science.

[0003] The core of MBBR technology lies in the biofilm suspension filler it uses. The filler has a large specific surface area and is easy for biofilm to grow on the surface. At the same time, its ingenious structural design makes the filler less likely to clump and clog during use. Microorganisms can attach to these fillers and fully contact with sewage as the fillers move, thereby achieving degradation and purification of organic matter in sewage.

[0004] The traditional moving bed biofilm reactor is directly aerated at the bottom, and the gas cannot fully stir the water flow, and thus cannot fully stir the biofilm suspended filler, resulting in incomplete degradation and purification of organic matter in sewage and low efficiency. Therefore, we proposed a combined device of ozone and moving bed biofilm reactor. Utility Model Content
