摘　　要：当氨氮废水中盐度过高时会抑制微生物活性,故常采用成本较高的物理化学方法进行处理。总结了近年来处理高盐废水中氨氮的有效生物方法,从处理效果和耐盐能力的角度,比较了各方法的优缺点,阐述出生物膜、污泥颗粒化、生物多样性和膜组件对提升生物法处理高盐废水氨氮的作用。同时,对废水高含盐量引起的(溶液中亚硝酸盐积累、污泥中难生物降解物质增加、出水浑浊、耐盐驯化时间长等)一系列问题进行了分析,并提出相应的解决方案。When the salinity of ammonia nitrogen wastewater is too high,microorganisms will be inactivated. Therefore,physicochemical methods high cost of treatment are often involved to treat this kind of wastewater. Many of effective biological treatment methods for ammonia nitrogen in high-salt wastewater were summarized in terms of treatment effect and salt tolerance. The advantages and disadvantages of each method were compared and the effects of biofilm,granular sludge,biodiversity and membrane module on the biological treatment of ammonia nitrogen in highsalt wastewater were elaborated. Some problems(nitrite accumulation in solution,inert content accumulation in sludge,turbidity in effluent,long term acclimation of salt tolerance) caused by the high-salt in waster wastewater were analyzed,and then the corresponding solutions were proposed.
