| 摘 要： | 在渗滤液回灌基础上,结合垃圾堆体本身为厌氧环境的特性,开发出的生物反应器垃圾堆体渗滤液原位脱氮技术已成为目前的研究热点。文章以从杭州市固体废弃物处理有限公司天子岭填埋场采集的不同填埋龄垃圾为试材,利用系列自制生活垃圾生物反应器模拟装置,通过回灌硝酸盐溶液,探讨了不同填埋龄垃圾在碳源充足情况下的反硝化性能特征。结果表明当垃圾堆体自身降解的有机物量充足时,1~12 a垃圾的反硝化性能均较强,且差异不大;所有反应器在最初的1 h内硝酸盐去除率最高,达70%~92%。这说明开发生物反应器垃圾堆体渗滤液原位脱氮技术具有一定的现实可行性。

| Abstract: | In-situ ammonia removal technique involving ex situ nitrification coupled with the use of landfill as a bioreactor for denitrification is under development.Refuse at different landfill ages were sampled from Hangzhou Tianziling Landfill and the denitrification capacities of the refuse were studied.Results showed that refuse at different landfill ages all had a considerably high denitrification capacity when the refuse body itself could provide enough organic carbon for denitrification.Nitrate reduction rates could reach up to 70%~92% in the first hour,which indicated that developing an new way for nitrogen removal with use of landfill as a bioreactor for denitrification had certain feasibility. |
