固定化Ralstonia metallidurans CH34在三相流化床中降解苯酚的研究

Study on Phenol-degradation by Immobilized Ralstonia Metallidurans CH34 in Three-phase Fluidized-bed

摘要:

通过探索固定化细菌Ralstonia metallidurans CH34在三相流化反应器中降解苯酚的反应条件，对固定化细胞处理工业废水进行模拟研究，以期提高R.metallidurans CH34降解苯酚的能力和效率。结果表明，固定化R.metallidurans CH34在三相流化反应器中明显提高了降解苯酚的能力，耐抗金属性也有较大的提高，而且能够在模拟工业废水中批次培养3-4次，其降酚能力退化并不明显。这为R.metallidurans CH34实际应用提供了可靠的基础。

Abstract:

The phenol degradation in three-phase fluidized-bed was investigated by using immobilized Ralstonia metallidurans CH34 cells with the aim to improve the efficiency of phenol degradation.The results indicated that the abilities to degrade phenol and resistant to heavy metals of R.metallidurans CH34 have been greatly improved by immobilized cells in three-phase fluidized-bed.The immobilized cells were stable after used for 3~4 batches repeatedly.The present results provided the reliable basis for the application of R.metallidurans CH34 in bio-treatment of phenol-containing industrial waster water.
