淮安市垃圾填埋场地质特征及其防渗评价
|
摘要
正确分析评价垃圾填埋场的地质特征和防渗方案,对垃圾填埋场的选址、设计以及施工运营极为重要。从自然环境、地层结构及岩性特征等方面阐述了淮安市某垃圾填埋场的地质特征,分析了填埋区含水层分布、厚度、赋水性等水文地质条件;结合室内试验和野外试验,综合确定了填埋区岩土层渗透系数大于1×10~(-7)cm/s,表明填埋区不具备天然防渗的条件,需采用人工防渗系统才能有效的阻滞垃圾渗滤液对周边环境的影响。
Correct analysis and evaluation of municipal waste landfill geological characteristics and seepage program play a very important role in municipal waste landfill siting and design and construction operations.The geological characteristics of municipal waste landfill in Huaian city,such as natural environment,Stratigraphic structure and lithology are described, hydrogeological conditions of municipal waste landfill,as well as aquifer distribution,aquifer thickness and permeable are analysed in detail in the paper.On the basis of laboratory test and in-situ tests,comprehensive determined of the strata permeability coefficient greater than 1×10~(-7)cm/s in municipal waste landfill siting,indicated that does not have natural anti-seepage conditions,must use the artificial anti-seepage system to be able effective to prevent pollution of environment form the leachate of refus.
