摘要
以陈垃圾和煤渣作为生物滤池反应器填料,分别构建了单一陈垃圾、煤渣以及复合该2种填料的生物反应器,对渗滤液中的污染物进行了去除效果实验.结果表明,煤渣生物滤池对于渗滤液中COD和氨氮的去除效果高于陈垃圾滤池,但是总氮的去除率低于陈垃圾.复合填料滤池对于负荷和低温变化具有较好的耐受能力.电镜观察和微生物计数结果表明,2种载体适合微生物挂膜生长.粒径分析结果表明,2种载体的颗粒粒径组成对于滤池通透性能以及污染物去除有重要影响.
Two different media,aged refuse and cinder were used to construct three biofilters,aged refuse biofilter,cinder biofilter and complex biofilter,and their treatment efficiency on landfill leachate pollutants were investigated.Cinder biofilter had higher COD and NH3-N removal rates than that of the aged refuse biofilter,while lower removal rate of total nitrogen.Complex biofilter had better resistance to shock loading and lower temperature.SEM observation and microbial counting found that two media were hospitable for bacterial attachment and growth.The particle composition of two media may have important effects on biofilter＇s permeability and pollutants removal.
