摘要
以武汉市二妃山垃圾填埋场为例 ,阐述了其垃圾填埋场的地形、地貌、水文地质等基本条件 ,并剖析了垃圾填埋过程中渗滤液产生的机理和特征 ;采用污染物在饱和与非饱和孔隙介质中迁移的基本方程式 ,预测评价了其渗滤液垂直下渗锋面影响到下伏含水层所需的时间 (年 ) ;根据场地内不同地段影响到含水层时间的长短 ,对照渗滤液的产生周期 ,并结合场地及其周边水文地质条件 ,提出了场地周边及其衬底防止渗滤液下渗的相关措施及对策。
Taking Er'feishan landfill site in Wuhan City as an example,we have first expounded such pestulates as terrain,physiognomy and hydrogeology and analysed.The mechanism and characteristics of the filtrate generated in the course of garbage filling.Then,we have predicted and evaluated the time(year) for the vertical leakage to affect the underlying acquifer.Finally,we have put forward some measurements and tactics to prevent the filtrate from leaking downward according to site how long the acquifer is affected in different areas of the landfill,the generation period of the leakage and the hydrogeology of the site and its surrounding areas.
