| 摘 要： | 从杭州市固体废弃物处理有限公司天子岭填埋场采集了1~12年填埋龄垃圾,通过对其基本理化性质的分析发现,不同填埋龄垃圾中以类似腐殖质的混合物为主,其次为塑料类;混合类物质含量随垃圾填埋龄的增加而上升。另外,由于填埋场含水率低,pH、TN(总氮)、BDM(生物可降解物)、HE(腐殖质可提取物)等指标在垃圾填埋4年后基本趋于稳定,垃圾进入降解缓慢期。这表明填埋场的传统操作模式不利于垃圾稳定化,开发以渗滤液回灌为特征的生物反应器填埋技术具有现实意义。

| Abstract: | Refuse of 1,2,3…12 years were sampled from Hangzhou Tianziling Landfill and the refuse properties were analyzed.The results showed that the mixtures which had similar performance with soil comprised the highest proportion in the refuse of different landfill ages,followed by plastics.Refuse in the landfill became relatively stable but not fully aged after being placed for four years primarily due to low water content.Therefore,in order to accelerate refuse decomposition,a reasonable approach is to develop bioreactor landfills characterized by leachate recirculation. |
