摘　　要：该文研究了水温24.2～31.0℃,HRT=1.5h的工况条件下,不同气水比对曝气生物滤池处理碱法草浆中段废水效果的影响;发现对浊度去除率的影响不大;气水比为3:1时的容积负荷可达4.3kgCOD/(m3·d),出水CODcr平均值为325mg/L,UV254去除率可达56.7%。The effect of different ratio of gas and water on treating soda straw pulping effluent using biological aerated filter is studied when temperature is 24.2-31.0℃ and HRT is 1.5 h; Small effect on removal of turbidity is observed; when the ratio is 3：1, load capacity can reach 4.3 kgCOD/（m3·d） ,average CODcr about outlet water is 325 mg/L, and removal of UV254 is over 56.7 %.
