| 中文摘要 |
| 进行了空气提升内循环生物流化床反应器内液体内循环速度、有机物降解动力学、载体表面生物膜脱落与增长动力学的研究。结果表明,内循环生物流化床内循环速度分别与反应器高度及升流区表观气速ug的0.5次方成正比;当内循环流量很大时,反应器可视为CSTR;生物膜的脱落率分别与ug及膜厚δ的一次方、载体数量的2/3次方成正比。 |
| 英文摘要 |
| Study on the liquid circulation velocity,organic matter degradation kinetics and bio film detachment rate in airlift biofilm suspension reactor was conducted.The results showed that the inner circulation velocity is proportional to the reactor height and the 0.5 power of the superficial gas velocity in the riser. The reactor can be treated as CSTR when inner circulation flux is high. The biofilm detachment rate is proportional to the first power of suPerficial gas velocity in riser and the biofilm thickness and the 2/3 power of carrier quantity in reactor,respectively. |
