摘要
研究水温24.2～31.0℃,HRT=1.5h的工况条件下,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;气水比为3:1时COD的容积负荷可达4.3kg·m-3·d-1,出水CODCr平均值为325mg·L-1,UV254去除率可达56.7%。
The effect of different ratio of air and water on treating soda straw pulping effluent using biological aerated filter was studied when temperature was 24.2-31.0℃ and HRT was 1.5h; Small effect on removal of turbidity was observed; when the ratio was 3：1, COD load capacity could reach 4.3 kg·m^-3·d^-1, average CODc, about outlet water was 325mg·L^-1, and removal of UV254 was over 56.7%.
