废弃物作垃圾填埋场覆盖材料室内试验研究

通过采集自来水厂污泥、脱水疏浚污泥、焚烧炉底灰、污水厂消化污泥以及污水厂未消化污泥 ,对其进行了物理性、力学性、水力性、热学性等一系列室内土工试验 ,考察其作为垃圾填埋场覆盖材料的可行性。根据试验结果 ,探讨了其特性产生的微观原因 ,初步筛选出可作为覆盖材料的废弃物 ,并认为需对研究对象改性处理。

Indoor Testing Study on Wastes as Covering Material of Refuse Landfill Yard

Through collecting waterworks sludge, dewatering and dredging sludge, fly-ash from incinerator, digestion sludge and un-digestion sludge from wastewater plant the paper makes a serious of indoor civil geo- technical test such as physical, mechanical, hydraulic and thermodynamic properties in order to investigate the feasibility of using it as the covering material of refuse landfill yard. According to the test result the paper approaches to the microscopic reason of the properties and the wastes that could be the covering material is preliminarily selected , but it remains the treatment before the application.
