| 摘 要： | 建立了模拟填埋试验中试装置,研究了准好氧填埋渗滤液NH3-N的变化特性和稳定期垃圾对渗滤液NH3-N的处理效果.结果表明,准好氧填埋结构下渗滤液NH3-N衰减很快,下降率可达99.6%,没有出现传统填埋场累积的现象,为渗滤液后续处理解决了氨氮浓度过高的难题;随着水力负荷的增大,NH3-N的去除率呈下降趋势,去除率由低水力负荷时的99.9%,下降到高水力负荷时的87.7%;准好氧填埋垃圾对低可生化性、高浓度氨氮的渗滤液有很好的处理能力,但反硝化能力不足;较高有机物浓度有利于反硝化作用,使氨氮彻底转化为氮气. |

| Abstract: | Two landfill installations were built according to semi-aerobic and anaerobic landfilling theories.In order to study the influence of landfill structure on removal of ammonia nitrogen,leachate was recirculated into a semi-aerobic landfill and an anaerobic landfill and the concentrations of NH_3-N were detected regularly.The results showed that,leachate recirculation in semi-aerobic landfill is beneficial to the decrease of NH_3-N in leachate,and the reducing rate of NH_3-N had reached to 99.6%.The affect of the hydraulic loading on removal of ammonia nitrogen is more important than concentrations of NH_3-N. |
| Keywords: | semi-aerobic ammonia nitrogen landfill leachate |
