渗滤液处理工艺调试运行出水水质达标的研究——工艺参数及活性污泥的驯化培养

Research on Adjusting and Running the Leachate Treatment Process to Meet the Standards of Effluent Water Quality:Process Parameters and Domestication Culture of Activated Sludge

渗滤液是垃圾填埋过程中产生的高浓度有机废水,成分复杂,若处理不当,会严重危害周边环境和污染地下水。渗滤液处理工艺的调试阶段极为重要,影响后期运行是否稳定和处理后的渗滤液是否能够达标排放,处理工艺的参数设置和活性污泥的培养驯化是十分重要的步骤。本文对北京市海淀区六里屯垃圾填埋场渗滤液处理设施工艺调试运行阶段的参数及活性污泥驯化培养进行了研究,在单项设施试运行和活性污泥培养的基础上,进行整个工艺的调试,以确保水处理能够按照设计标准达标排放。

Leachate is a high concentration organic wastewater generated during the landfill process,with complex components.If not treated properly,it can seriously harm the surrounding environment and pollute groundwater.The debugging stage of the leachate treatment process is extremely important,which affects the stability of later operation and whether the treated leachate can meet the discharge standards.The parameter setting of the treatment process and the cultivation and domestication of activated sludge are very important steps.This article studies the parameters and domestication cultivation of activated sludge during the process debugging and operation stage of the leachate treatment facility at the Liulitun landfill site in Haidian District,Beijing.Based on the trial operation of individual facilities and the cultivation of activated sludge,the entire process is debugged to ensure that the water treatment can meet the design standards for discharge.
