| 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4．3kg COD／（m^3·d），出水CODcr平均值为325mg／L，UV254去除率可达56．7％。

| Abstract: | 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 %. |
