Novel in-situ double-sealing treatment process for full-amount recycling of landfill leachate
The invention belongs to the technical field of harmless treatment of refuse landfills, and particularly relates to a novel in-situ double-sealing treatment process for full-amount recycling of landfill leachate. The in-situ double-sealing treatment process comprises a sealing slurry, a mixing ratio of the sealing slurry, and a slurry preparation and spraying sealing process. The sealing slurry comprises power plant furnace bottom slag or mineral slag, mixed grinding ash, cement and curing agent powder. The slurry preparation and spraying sealing process comprises the following steps: S1, pre-drying the power plant furnace bottom slag or mineral slag, and adding the pre-dried power plant furnace bottom slag or mineral slag into a large stirrer of a stirring station arranged at a proper position of a refuse landfill; S2, extracting the landfill leachate from a landfill leachate pool, adding the landfill leachate into a stirrer, and stirring for 3-6 min; S3, sequentially adding the mixed grinding ash, the cement and the curing agent into a stirrer through automatic metering according to the matching amount, and stirring for 2-3 min; and S4, unloading the uniformly stirred slurry into a spraying vehicle through the stirrer, and pulling to a garbage yard for spraying and covering the garbage.
本发明属于垃圾填埋场无害化处理技术领域，具体涉及垃圾渗滤液全量资源化原位双封固处理新工艺，所述的原位双封固处理新工艺包括封固浆料及其配合比以及制浆及喷涂封固工艺流程；所述的封固浆料包括电厂炉底渣或矿渣、混磨灰、水泥、固化剂粉体，所述制浆及喷涂封固工艺包括以下步骤，S1：将电厂炉底渣或矿渣预烘干，加入设在垃圾填埋场合适位置的搅拌站之大型搅拌机中；S2：从垃圾填埋场渗滤液池中抽取垃圾渗滤液，加入搅拌机，搅拌3～6分钟；S3：依次按配比量经自动计量将混磨灰、水泥、固化剂依次加入搅拌机，搅拌2～3分钟；S4：将搅拌均匀后的浆体由搅拌机卸入喷涂车，拉至垃圾场进行对垃圾的喷涂覆盖。
