摘　　要：采用新型两相分配式生物反应器(TPPB)和前期研究得到的高效苯酚降解菌对高盐废水中苯酚的降解进行研究,研究中确定煤油为反应系统的最佳有机溶剂,并考察了废水苯酚含量、废水盐度以及搅拌器搅拌速度对苯酚降解的影响。结果表明,反应系统能正常降解苯酚含量为1 000～2 500 mg/L的高盐苯酚废水;反应系统在含盐量为100 g NaCl/L、搅拌速度为50 r/min的运行工况条件下,降解时间缩短为52 h,总酚去除率为20.58 mg/(L.h)。Degradation conditions of phenol based on the novel two-phase partitioning bioreactor （TPPB） and the phenol-degrading bacteria which overcomes the difficulties found in the removal of phenol in high salinity wastewater were studied. Optimal organic solvent of the reaction system was kerosene. And the phenol concentration, salinity and agitation speed of the process were examined. The experimental results reveal that the reaction system could degrade phenol range from 1 000 mg/L to 2 500 mg/L. Under the optimal operation conditions of the salt concentration of 100 g/L and agitation speed of 50 r/min, the degradation time was shortened to 52 h with total phenol removal rate of 20. 58 mg/（ L · h）.
