摘　　要：采用倒置A2/O工艺同步处理垃圾渗滤液与城市污水脱氮.结果表明:水力停留时间对脱氮影响较为显著,试验条件下水力停留时间至少应维持9 h;好氧池溶解氧浓度增加对总氮去除不利;在60%～100%的范围内提高污泥回流比对有机物和总氮去除有利;混合液回流比对有机物和氨氮的去除基本不产生影响,在100%～200%范围内增加对反硝化有一定促进作用.Nitrogen removal in the consolidated treatment of leachate and municipal wastewater by reversed A2/O process was studied,in the experiment,the results showed that HRT was the key factor for nitrogen removal efficiency.HRT should be long to 9 hours under the test conditions.The dissolved oxygen of the aerobic basin increase is hurt to total nitrogen removal.At the range of 60% to 100%,improving the sludge return ratio could get better organic and denitrification removal treatment effect.At the range of 100% to 200%,improving the mixed-liquor return ratio could get better denitrification removal treatment effect.
