    • Biological nutrient removal (BNR) in municipal wastewater treatment to remove carbonaceous substrates, nutrients and phosphorus, has recently become increasingly popular worldwide due to increasingly stringent regulations. Biological fluidized bed (BFB) technology, which could be potentially used for BNR processes, can provide some advantages such as high efficiency and compact structure. This present invention incorporates the fixed-film biological fluidized bed technology with the biological nutrient removal in a liquid-solid circulating fluidized bed, which has achieved the simultaneous elimination of organic carbon, nitrogen and phosphorus, in a very efficient manner and with very compact space requirements. The BNR-LSCFB has two fluidized beds, running as anoxic/anaerobic and aerobic processes to accomplish simultaneous nitrification and denitrification and to remove carbonaceous substrates, nutrients and phosphorus, with continuous liquid and solids recirculation through the anoxic/anaerobic bed and the aerobic bed. The new BNR-LSCFB system is not only an excellent alternative for conventional activated sludge type BNR technologies but is also capable of processing much higher loadings and suitable for industrial applications.
    • 在城市污水处理中去除碳质底物,营养物质和磷的生物营养物去除(BNR)由于日益严格的法规,近来在全世界越来越流行。 生物流化床(BFB)技术可用于BNR工艺,具有效率高,结构紧凑等优点。 本发明将固定膜生物流化床技术与生物养分去除技术结合在液固循环流化床中,该技术以非常有效的方式实现了同时消除有机碳,氮和磷,并具有非常紧凑的空间 要求。 BNR-LSCFB具有两个流化床,作为缺氧/厌氧和好氧工艺来完成同时的硝化和反硝化作用,并去除含碳底物,营养物质和磷,连续液体和固体再循环通过缺氧/厌氧床和好氧床。 新的BNR-LSCFB系统不仅是传统活性污泥型BNR技术的极佳替代品,而且还能够处理更高的负荷并适用于工业应用。
