浅析城市生活垃圾填埋场渗滤液处理工艺

Analysis of Treatment Technology of Landfill Leachate in City Life

城市生活垃圾以填埋为主,受各种因素的影响,垃圾填埋场渗滤液的污染问题尤为突出。文章首先分析了城市生活垃圾渗滤液的来源和特点,研究认为,渗滤液主要来源于大气降水、地下水、地表水、游离水和垃圾的化学分解;然后,就渗滤液的处理工艺从物理处理、化学处理和生物处理三个方面进行了详细阐述;文章认为,在选择渗滤液处理工艺时应具有针对性,因地制宜,采用最为合理的组合处理工艺。

City life waste is mainly filled with landfill.Influenced by various factors,pollution of landfill leachate is prominent particularly.Firstly,this paper analyzes source and characteristics of city life garbage leachate.It is believed that leachate mainly comes from chemical decomposition of atmospheric precipitation,groundwater,surface water,free water and garbage.Then,treatment process of leachate is elaborated from three aspects:physical treatment,chemical treatment and biological treatment.It is suggested that the most reasonable combined treatment process should be adopted in accordance with local conditions.
