| 摘 要： | 考察了移动床生物膜反应器（MBBR）处理石化废水时在相同水力停留时间下，不同填充率对污染物去除率和氧传递速率的影响。结果表明，填料填充率为30％时，污染物COD和氨氮去除率达最大值，其中COD去除率达90．98％；氧总传递系数12．66，是无填料时的1．48倍；温度20℃时氧传递系数达10．98，是无填料时的1．44倍。因而在MBBR处理石化废水时，适宜的填料填充率为30％。 |

| Abstract: | The influences of different packing percentages on removal of pollutants and rate were investigated in the same hydraulic retention time （HRT） when treating refinery the oxygen - transfer wastewater with moving bed biofilm reactor （MBBR）. The results indicated when the packing percentage was 30%, the removal rate of COD,and ammonia - nitrogen was the best with the former up to 90.98%, and the total transfer coefficient for oxygen was 12.66 which was 1.48 times of that with empty bed, and the total transfer coefficient was 10.98 at 20 ℃ which was 1.44 times of that with empty bed. So the suitable packing percentage on treatment of refinery wastewater with MBBR was 30%. |
