摘要： Biological nutrient removal (BNR) in 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 twin liquid-solid 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-LSFB 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-LSFB 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.
摘要翻译：废水处理中的生物营养物去除（BNR）在去除碳质底物，营养物质和磷的情况下，由于日益严格的规定，在全球越来越受欢迎。可以用于BNR工艺的生物流化床（BFB）技术可以提供高效率，结构紧凑等优点。本发明结合了固定膜生物流化床技术与双液固体流化床中的生物营养去除技术，以非常有效的方式实现了有机碳，氮和磷的同时消除，并且非常紧凑的空间要求。 BNR-LSFB具有两个流化床，作为缺氧/厌氧和需氧过程运行，以通过缺氧/厌氧床和需氧床连续的液体和固体再循环来完成同时硝化和反硝化并除去含碳底物，营养物和磷。新的BNR-LSFB系统不仅是常规活性污泥型BNR技术的出色替代品，而且还能够加工更高的载荷并适用于工业应用。

摘要： 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.
