【摘要】 采用厌氧生物滤池—好氧移动床工艺(AF—MBBR)处理垃圾卫生填埋场高盐渗滤液。结果表明:好氧移动床生物反应器对渗滤液中的氨氮具有非常高的去除率;但高盐量对AF—MBBR去除COD产生了明显的抑制作用,致使对COD的平均去除率仅为22%。经研究发现从垃圾渗滤液中分离、筛选出的专性耐盐菌,对高盐渗滤液生物处理系统具有显著的强化作用。更多还原

【Abstract】 An experiment on the biological treatment of landfill leachate with high salinity from Binhai landfill was carried out.A combined biofilm process of the Anaerobic Biofilter(AF) and the Moving Bed Biofilm Reactor(MBBR) were used.The experimental results indicate that the MBBR can remove ammonia nitrogen with high efficiency;but high salinity causes a remarkable inhibited effect on the removal of COD by AF-MBBR,causing the average removal efficiency of COD to be 22%.The specific strain of halotolerant bacteria isolated and screened from the landfill leachate has a remarkable enhanced effect on the biological treatment system.更多还原
