Anti-seepage adsorption lining for refuse landfill in loess area and application of anti-seepage adsorption lining
The invention belongs to the technical field of household garbage sanitary landfill anti-seepage system treatment, and particularly relates to a novel anti-seepage adsorption lining for a loess area garbage landfill and application of the novel anti-seepage adsorption lining. The anti-seepage adsorption lining is composed of 70%-85% of loess, 10% of attapulgite and 5%-20% of auxiliary materials, wherein the auxiliary materials are lime or cement. The preparation method of the anti-seepage adsorption lining comprises the following steps: preparing the loess, the attapulgite and the auxiliary materials according to the optimal water content, and carrying out layered filling and compaction to reach the maximum dry density, so as to obtain the anti-seepage adsorption lining. The attapulgite is adopted to modify the loess, the optimal ratio of the attapulgite to the loess is researched, and finally the novel composite lining with seepage-proofing and adsorption functions is prepared. The invention provides a novel impermeable composite material with low price for construction of the refuse landfill in the loess area, and the cost of impermeable treatment of the refuse landfill is greatly reduced.
本发明属于生活垃圾卫生填埋场防渗系统处置技术领域，具体涉及一种用于黄土地区垃圾填埋场的新型防渗吸附内衬及其应用。该防渗吸附内衬由70％‑85％黄土、10％凹凸捧土和5％‑20％辅料组成，其中辅料为石灰或水泥。该防渗吸附内衬的制备方法为将黄土、凹凸棒土和辅料按照最佳含水率进行配置，分层填筑击实以达到最大干密度，得到防渗吸附内衬。本发明采用凹凸捧土改性黄土，研究出凹凸棒土和黄土的最佳配比，最终制得兼具防渗和吸附功能的新型复合内衬。本发明为黄土地区垃圾填埋场的修建提供了一种价格低廉的新型防渗复合材料，大大降低了垃圾填埋场防渗处理的成本。
