摘　　要：研究了矿化垃圾生物反应床处理含酚废水的工艺参数。矿化垃圾生物反应床在经过驯化后,形成了稳定的微生物系统,反应床对有机酚具有较高的去除率。有机酚的去除率受湿干比影响较大,随着配水速率的提高,反应床对有机酚的去除率逐渐下降,配水速率大于0.342cm/min时,去除率急速下降。在进水有机酚质量浓度为20mg/L,连续配水时间6h,湿干比为1∶8,配水速率为0.254cm/min的条件下,反应床出水可达到或接近国家三级排放标准。A bioreactor made by the aged refuse was investigated to treat the wastewater containing phenolic pollutants. The parameters such as introduction time of wastewater, hydraulic load, phenolic concentrations in wastewater etc. , were tested to get the optimum operational conditions. After 6 months of domestication, stable microorganism system was formed. The aged-refuse hioreactor can be used to effectively remove the phenolic pollutants from the aqueous solutions, and the hydraulic load had great effect on the pollutants removal, when it reached 0.342 cm/min, the removal efficiency was declined rapidly. When the bioreactor was operated at 6 h of continuous water allocation, 1 ： 8 of wet/dry ratios, 0.254 cm/min of hydraulic load, the effluent of bioreactor conforms to the requirement of third Grade National Discharge Standard.
