摘　　要： 在自制的流化床光生物反应器中加入固定化藻菌小球来处理饮料废水,主要探讨了反应器中气速、液速以及固定化藻菌小球密度对系统去处效率的影响。在平均停留时间为6h,光照强度为4000lx,温度为室温,试验结果表明:COD的去除率最高可达到91.8%,NH+4-N的去除率最高可达到89.4%,对BOD、PO43--P的去除率也达到较好的效果,分别达到72.1%～85.5%和59.5%～68.0%。 The experiments carried in the fluidized photobioreactor for treating beverage wastewater by putting in the immobilized algal-bacterial beads, with discussion of the effect of gas velocity,liquid velocity and the density of immobilized algal-bacterial on the removal efficiency. At the room temperature,HRT was 6 hours and the light intensity was about 4000lx, experiment results showed that the highest removal efficiency of COD and NH4＋-N were 91.8%and 89.4% respectively. It also indicated that good removal efficiency of BOD and PO4^3-P, which were 72.1%-85.5% and 59.5%-68.5% respectively.
