摘　　要：在实验室中,通过人工药物加强的方式制造一系列的氧化还原带,观察各氧化还原带对渗滤液降解率的影响。实验结果表明:TOC降解率自大到小分别为氧还原带>产甲烷带>硫酸盐还原带>硝酸盐还原带>铁还原带,氨氮降解率基本相同,分别为:15.1%、15.1%、14.2%、15.7%、14.7%。In the laboratory,a series of redoxzones were made through artificial and chemical intensification,and the influences of each redoxzone on the degradation rate of the leachate were observed.The results show that TOC degradation rate of oxygen reduction zone （16%）〉 TOC degradation rate of methanogenic zone （12.6%）〉 TOC degradation rate of sulfate reduction zone （10.1%）〉 TOC degradation rate of nitrate reduction zone（9.0%） 〉TOC degradation rate of iron reduction zone（6.2%）;ammonia nitrogen degradation rates of abovementioned five zones are essentially the same：15.1%,15.1%,14.2%,15.7% and 14.7%.
