Durable and stable pollutant degradation system for refuse landfill
The invention relates to the technical field of garbage treatment, and particularly relates to a durable and stable pollutant degradation system for a refuse landfill. The durable and stable pollutantdegradation system for the refuse landfill comprises anti-seepage isolation layers, a biodegradation layer, a rainwater blocking layer, an underground drainage system and a supporting frame; the anti-seepage isolation layers are located on the periphery and inner side of the bottom of the landfill and used for carrying out seepage isolation on the landfill; the biodegradation layer covers the upper surface of a garbage body and is used for decomposing garbage and landfill gas; the rainwater blocking layer covers the top of the biodegradation layer and is used for blocking rainwater at the topof the landfill; the underground drainage system is located on the lower layer of the anti-seepage isolation layers at the bottom; the supporting frame is formed by splicing module units, each moduleunit comprises a rod body structure with the section being an isosceles trapezoid, a cavity is formed inside each rod body structure, the surface where the lower bottom of the trapezoid is located faces the inner side of the landfill, and filtering holes are evenly distributed in the surface where the two waists of the trapezoid are located; and the longitudinal support part is buried in a rubberlayer. According to the durable and stable pollutant degradation system for the refuse landfill, the pollutant degradation system for the refuse landfill maintains long-term structural stability andhas a better use effect.
本发明涉及垃圾处理技术领域，具体涉及一种耐久稳定型垃圾填埋场污染物降解系统，包括：防渗液隔离层，位于填埋场四周及底部内侧，用于对填埋场进行渗透隔离；生物降解层，覆盖于垃圾堆体上表面，用于对垃圾和填埋气进行分解；雨水阻隔层，覆盖于生物降解层顶部，对填埋场顶部进行雨水阻隔；地下排水系统，位于底部的防渗液隔离层下层；支撑框架，通过模块单元拼接而成，模块单元包括截面为等腰梯形的杆体结构，杆体结构内部为空腔，梯形的下底所在面朝向填埋场内侧，梯形的两腰所在面上均匀分布有过滤孔；纵向支撑部分填埋在碎石层内。通过本发明，使得垃圾填埋场污染物降解系统保持长期的结构稳定性，具有更优的使用效果。
