摘　　要：研究了用高铁酸盐处理经SBR法处理后的垃圾渗滤液。结果表明,COD和氨氮去除的最佳pH值分别为5和9,随着高铁酸盐用量的增加,去除率先达到一个峰值后经历一个回落阶段,然后再继续上升,COD和氨氮的最大去除率分别为80%和73%。Treatment of landfill leachate from SBR process by ferrate was studied. The results showed that the optimal pH on COD and NH3-N removal were 5 and 9, respectively. As the dose of ferrate increased, the removal rates underwent decline steps after reached peak values, then mounted up sequentially. The maximal removal rates of COD and NH3-N were 80%and 73%.
