Safe closure method for hazardous waste flexible landfill
The invention relates to the technical field of flexible landfills, in particular to a safe closure method for a hazardous waste flexible landfill, which comprises the following steps: measuring a laying area of a landfill body, and selecting a matched laying material according to the measured size; the hazardous waste layer is compacted, and a silicon powder layer is laid on the hazardous waste layer; a gas guide layer, an impermeable layer, a drainage layer and a vegetation layer are sequentially laid on the upper portion of the silicon powder layer from bottom to top, the edge of the impermeable layer is arranged in the anchoring ditch, the edge of the drainage layer is arranged in the flood intercepting ditch, and the flood intercepting ditch is arranged on the side, away from the landfill body, of the anchoring ditch; fixing the edges of the impermeable layer and the drainage layer; carrying out geogrid fixation on the vegetation layer; and checking and accepting the laid closure system. The closure structure is stable, soil layer landslide caused by rainwater erosion is avoided, environmental friendliness is achieved, the ecological restoration and reclamation utilization speed of the landfill is increased, and higher safety is achieved.
本发明涉及柔性填埋场技术领域，具体为一种危险废物柔性填埋场安全封场方法，包括以下步骤：对填埋场本体的铺设区域进行丈量，根据丈量的尺寸选择相匹配的铺设材料；将危险废物层压实，并在危险废物层上面铺设硅粉层；在硅粉层上方从下到上依次铺设导气层、防渗层、排水层、植被层，所述防渗层边缘设置在锚固沟内部，所述排水层边缘设置在截洪沟内部，截洪沟设置在锚固沟远离填埋场本体的一侧；对防渗层、排水层边缘进行固定；对植被层进行土工格栅固定；对铺设完成的封场系统进行检验验收。本发明封场结构稳定，避免雨水冲蚀产生的土层滑坡，对环境友好，提高了填埋场的生态修复和复垦利用速度，更具有安全性。
