摘　　要：微好氧颗粒污泥工艺能够同时进行好氧氧化和厌氧还原过程,是处理五氯酚(PCP)的理想方法。对影响好氧颗粒污泥降解PCP的因素水力学上升流速、碱加入量以及水力停留时间进行考察。结果表明,水力学上升流速为4.58 m/h,进水NaHCO3浓度为900 mg/L,水力停留时间为24 h时,处理效果比较好。It is an approved technology of microaerobic granular sludge to degrade pentachlorophenol （PCP） because aerobic oxidation and anaerobic reduction can simultaneously occur. In this paper, effects of hydraulic upward velocity, the addition amount of NaHCO3 and hydraulic retention time on PCP degradation with microaerobic granules were studied. The results showed satisfactory treatment efficiency was obtained when hydraulic upward velocity was. 4.58 m/h, the addition amount of NaHCO3 was 900 mg/L and hydraulic retention time was 24 h.
