Under the graduated design of information provided and water emissions, the current design using aerobic biological sulfide fluidized bed technology. Biological Process water, biological fluidized bed technology is a new type of membrane technology, 20 in the early 1970s to develop the beginning of the 20th century, after the 1980s, the technology applications become more active. Biological fluidized bed as a new water treatment technology has shown its advantages, there is good prospects for development. At the moment it promote the use of energy is one of the factors other than biological treatment slightly larger. To reduce energy consumption, from the reactor to the rational design of the structure, Carrier selection and operation of the optimal control parameters such as conducting studies. Because China's research in this area work started late, funding and manpower inputs limited, it is difficult to industrial technology. In the future this area must strengthen basic research, to promote the use of technology to provide the foundation. Biological fluidized bed technology is a new type of aerobic biological treatment, It is common activated sludge and biofilm organically combines the advantages together, and the introduction of the flow of technology to the treatment of organic wastewater, which is high-volume load, biodegradable fast, The size of a small, infrastructure investment and the advantages of low cost operations, is the most advanced aerobic biological treatment. The design of the aeration biological fluidized bed with a three-dimensional hollow cylindrical packing for the carrier filling in bed, through aeration sewage in a certain velocity flow from top to bottom, in the flow of carrier-hormone another coating device. As the tanks fill active surface area, as a general pool of biochemical 16-20 times (with unit volume). Therefore tanks to maintain high biomass, high speed the removal of organic pollutants purposes.
