某高龄期大型垃圾填埋场矿化垃圾理化特性与资源化利用研究*张俊文，苏兴国，李湛江，黄亚玲，李瑾（广州市城市管理技术研究中心，广东广州510170）【摘要】为探索高龄期大型垃圾填埋场矿化垃圾资源化利用情况，以某80年代末垃圾填埋场矿化垃圾为例，多点勘探采集矿化垃圾和渗滤液样品进行理化特性分析，并对垃圾堆体开展沉降监测。结果表明：填埋场堆体沉降趋于稳定，渗滤液无法满足排放要求，须处理达标后排放；矿化垃圾中可燃组分含量约为23%~31%，腐殖土含量约为65%~75%，其湿基低位热值符合垃圾焚烧处理最低热值要求，但灰分含量较高（约为62%），不宜直接焚烧处理；建议矿化垃圾按可燃组分、腐殖土、金属类和砖瓦石块筛分分类进行资源化利用。【关键词】封场；填埋场；资源化利用；矿化垃圾；理化特性中图分类号：X705；X703文献标识码：A文章编号：1005-8206（2023）01-0081-06DOI：10.19841/j.cnki.hjwsgc.2023.01.013ResearchonthePhysicochemicalCharacteristicsandResourceUtilizationofMineralizedWasteinAnOldLargeLandfillZHANGJunwen，SUXingguo，LIZhanjiang，HUANGYaling，LIJin（GuangzhouCityManagementTechnologyResearchCenter，GuangzhouGangdong510170）【Abstract】Inordertoexploretheresourceutilizationofmineralizedwastefromanoldlargelandfill，themineralizedwastefromalandfillinthelate1980swastakenasanexample.Thephysicochemicalpropertiesofmineralizedwasteandleachatesampleswereanalyzedbymulti-pointexploration，andsettlementmonitoringwascarriedout.Theresultsshowedthatthelandfillpilesettlementtendedtobestable，leachatecouldnotmeetthedischargerequirementsandmustbedischargedaftertreatmenttomeetthestandards.Thecombustibleingredientsofthemineralizedwastewasabout23%~31%，thehumuswasabout65%~75%，anditswet-basedlowcalorificvaluemettheminimumcalorificvaluerequirementofwastetreatmentbyincineration.However，theashcontentwashigh（about62%），andwasnotsuitablefordirectincinerationtreatment.Itwasrecommendedthatthemineralizedwasteshouldbescreenedandclassifiedaccordingtocombustible，humus，metalandbrickstonesforresourceutilization.【Keywords】closureoflandfill；landfill；resourceutilization；mineralizedwaste；physicalandchemicalproperties1引言垃圾...
