FBC technology is Thunip Water (Beijing) Co., Ltd. original phosphorus denitrification new process, is the world, temperate climate conditions, 250,000 tons / day large-scale wastewater treatment plant to achieve mainstream anaerobic ammonia oxidation of the first successful application of the leading international level.FBC technology is mainly used in the new wastewater treatment plant, wastewater treatment plant upgrading, industrial wastewater treatment, etc., low-temperature and low carbon and nitrogen ratios, save carbon sources. The low temperature and low carbon to nitrogen ratio can save carbon source, and the discharge standard can be up to quasi-IV water body.

FBC technology through the anaerobic area and anoxic area, aerobic area by adding fluidized biological filler to the activated sludge activity system optimization or set up an independent post anoxic filler area, is to strengthen the biological nitrogen removal of phosphorus and improve the quality of wastewater treatment plant effluent water - an effective method. fbc process is the traditional biofilm process and the activated sludge process in the anaerobic, anoxic, aerobic section of the organic combination of the process, that is, with the help of moving bed biofilm process and activated sludge process in the anaerobic, anoxic, aerobic section of the organic combination. That is, with the help of the characteristics of the moving bed biofilm process, in the biological reaction tank, add suspended filler can hang film, filler has a high specific surface area, biofilm in the filler inside and outside the surface of a large number of growth. In anoxic or anaerobic reactor, FBC process is realized by mechanical mixing and pushing flow; in aerobic zone, FBC process is realized by air mixing. This process realizes anaerobic ammonia oxidation and strengthens anaerobic hydrolysis and acidification in anaerobic zone; anaerobic ammonia oxidation, short-range denitrification and traditional denitrification in anoxic zone; and carbonization and nitrification in aerobic zone. fbc process is a kind of energy-saving and carbon-saving process, and it can also reduce the sludge output.
