摘要
生物反应器填埋场要求临时覆盖材料具有较强的渗透能力和一定的均衡回灌渗滤液流动的能力。通过比较,认为生物反应器填埋场在运营前期宜采用粉质砂土、黄土或轻亚粘土作临时覆盖材料,后期采用稳定垃圾分选的细粒物作临时覆盖材料,在雨季时还可配合使用塑料布防止过多的降水进入场内。
Materials used for temporary cover of bioreactor landfills should have moderate abilities of penetration and unbalanced seepage of garbage. This paper indicates that silty sand soil, loess and light sub clay are suitable for this kind of use in the early stage of landfill operation and soil separated from the stabilized garbage can be used in later stage. However during rainy season, it is recommended to use plastic blankets keeping water from entering into the landfill site.
