摘　　要：归纳了生物铁法的类型和适用条件,分析了不同生物铁法强化污水生物处理的作用机理、优缺点和运行成本;总结了各类型生物铁法在脱氮除磷和难降解有机废水处理中的应用研究现状。与Fe(Ⅲ)-生物铁法和Fe(Ⅱ)-生物铁法相比,认为Fe^0-生物铁法具有投资和运行成本低、工艺简单、强化效率高等特点,是生物铁法强化污水处理研究与应用的新方向。为了能更好地实现Fe^0-生物铁法工程化应用,还需在新型零价铁材料的开发和工艺参数的优化等领域进行进一步研究。The type and application condition of different bioferric process in wastewater treatment was concluded, strengthening mechanism, advantages, disadvantages and operating cost were analyzed simultaneously. The research situation of applications of different bioferric process in nitrogen and phosphorus removal and refractory organic wastewater treatment were also summarized. Compared with Fe(Ⅲ)-bioferric process and Fe(Ⅱ)-bioferric process, Fe0- bioferric process was characterized by low investment and operating cost, simple process and high efficiency, which was supposed to be the new trend of research and application on biological enhanced wastewater treatment. Meanwhile, in order to promote the widely engineering application of Fe0- bioferric process, more research should be focused on the development of new type zero-valent iron materials and optimization of technological parameters.
