摘要
针对北京市安定垃圾填埋场渗滤液采用回喷法处理的技术缺陷 ,提出了有效的物理化学处理工艺流程 :混凝—氧化—吸附剂吸附作为回喷法的预处理。实验结果表明 :COD去除率可达 80 %以上 ,色度去除率达 90 %以上 ,臭味消失。经过该流程处理后的渗滤液可以回喷处理或用做灌溉、绿化 。
Since there exist defects in present leachate sprayi ng-back circulation treatment technology, an effective physical-chemistry treatm ent process was introduced as pretreatment before spraying-back circulation: co agulating-oxidation-adsorption by inhalant. The experiment showed that the eli mination rate of COD is more than 80% and that of chroma is more than 90% and t he offensive odor disappeared. The possibility of leachate recycle in landfill s ite was discussed. The leachate can be recirculated and spray on the solid waste or be used for irrigation and planting.
