Solid waste landfill bottom anti-seepage system leakage point repairing method and repairing material thereof
The invention provides a method for repairing a leakage point of an anti-seepage system at the bottom of a solid waste filling field. The method comprises the following working steps: S1) accurately positioning a leakage point part in the solid waste filling field; s2) directionally drilling an inclined shaft from the outer side of the slope of the solid waste landfill to the direction of the potential leakage point part, wherein the inclined shaft extends into the solid waste landfill to cover the leakage point part; 3) extracting and collecting leachate, sludge and residues accumulated in the inclined shaft, and performing subsequent harmless treatment; and S4, a waste biomass leakage point repairing material based on loaded sodium percarbonate is injected into the inclined shaft, oxidation repairing is conducted on soil and underground water around the leakage point, and then a thermoplastic protection film is sprayed on the repairing material. The technical problems that in the prior art, the repairing work amount of the bottom leakage points of the solid waste landfill is large, cost is high, consumed time is long, and peculiar smell is large can be solved.
本发明提供一种固废堆填场底部防渗系统漏点修复方法，包括如下工作步骤：S1）准确定位固废堆填场中的漏点部位；S2）自固废堆填场边坡的外侧向所述潜在漏点部位的方向定向钻斜井，所述斜井延伸至所述固废堆填场内覆盖所述漏点部位；3）抽取并收集所述斜井内积存的渗沥液、淤泥及残渣，进行后续无害化处置；S4）向所述斜井中注入基于负载过碳酸钠的废弃生物质漏点修复材料，对渗漏点周围土壤地下水进行氧化修复，再在修复材料上喷涂热塑保护膜。本发明能够解决现有技术中固废堆填场底部漏点修补工程量大、成本高、耗时长、异味大的技术问题。
