摘　　要：研究以陶粒粒子为载体,采用快速排泥挂膜法,在内循环三相流化床反应器运行过程中逐渐加大进水量和进水浓度,使微生物适应高氨氮废水环境;研究了水力停留时间、NH4+-N浓度负荷冲击对NH4+-N去除率的影响.结果表明:内循环三相流化床可用于处理高NH4+-N废水;底物浓度越高水力停留时间越长;内循环三相流化床具有较好的抗负荷冲击能力,有利于解决实际废水水质不稳定难以达标排放的困难.In the present study,the microbiology was adjusted to the wastewater which contains high level nitrogen by gradually increasing the inflow and influent concentration in the inner-loop three-phase biological reactor with ceramic particles as the carrier and using fast discharging sludge method to culture aerobic biofilm.The influence of hydraulic retention time,ammonia nitrogen concentration on ammonia nitrogen removal rate was also investigated.The results showed that inner-loop three-phase fluidized bed can be used to treat the wastewater which contains overrich ammonia nitrogen.The elevating capacity of inner-loop three-phase fluidized bed was better than other reactors and could be used to make the wastewater reach the emission standard.
