【摘要】：根据国内外新型导排水材料——毛细透排水带的现有应用和相关研究,结合填埋场导排系统容易发生堵塞的现状,首次提出将毛细透排水带用于国内填埋场渗滤液导排系统的全新应用方向;并开展了室内模拟对比实验研究。结果表明,毛细透排水带在渗滤液导排系统未发生堵塞时,不能起到关键性作用,而当其发生堵塞时,毛细透排水带可大大增强渗滤液的导排能力,使渗滤液及时排出;且实验结果证明,水头越高,越有利于毛细透排水带发挥导排作用,导排层被堵塞的越严重,导排效果越好。
[Abstract]:According to the existing application and related research of the new type of conductive and drainage materials-capillary permeable drainage belt at home and abroad, combined with the current situation that the guided-discharge system of landfills is prone to clogging. It is the first time to put forward the new application direction of capillary permeable drainage belt in domestic landfill leachate drainage system. The results show that the capillary permeable drainage zone can not play a key role when the leachate drainage system is not blocked, but when it occurs, the experiment results show that the capillary permeable drainage zone can not play a key role when the leachate drainage system is not blocked. Capillary permeable drainage zone can greatly enhance the leachate drainage capacity, so that the leachate can be discharged in time; The experimental results show that the higher the water head, the more conducive to the capillary permeable drainage zone to play the role of guide and drainage, the more serious the guide layer is blocked, the better the effect of guide and drainage.
