WASTE VOLUME REDUCTION TREATMENT METHOD IN LANDFILL WASTE DISPOSAL SITE
PROBLEM TO BE SOLVED: To provide a waste volume reduction treatment method where a volume reduction treatment can be performed even in a waste disposal site capable of not maintaining a compaction hole in a landfill and the like since the volume reduction treatment method of the waste disposal site that excavated waste as it is is compacted to a pore wall to form a non-discharge excavated hole (compaction hole) and surface layer refuse and transported refuse are charged into the compaction hole is hardly performed in a landfill waste disposal site in which a hydrous laminate waste layer A exists.SOLUTION: In a waste volume reduction treatment method, a volume reduction treatment step where a new waste disposal space consisting of a non-discharge excavated hole D is formed and a surface layer waste E is charged is performed after a drain compaction step where a drain material is installed in the volume reduction object range of a laminate waste in a landfill waste disposal site and seepage water in a hydrous laminate waste layer A is compacted to a non-hydrous laminate waste layer B by performing forced discharge due to vacuum suction.
【課題】含水積層廃棄物層Ａが存在する埋立地廃棄処分場は、そのままの状態では掘削ゴミを孔壁に圧密して無排出掘削孔（圧密孔）を形成し、前記圧密孔に表層ゴミや搬入ゴミを投入する廃棄物処分場の減容処理工法が困難である。このような埋め立て地等の圧密孔を維持できない廃棄物処分場でも、前記減容処理を可能とする。【解決手段】埋立地廃棄物処分場の積層廃棄物の減容対象範囲にドレーン材を打設して、含水積層廃棄物層Ａ内の浸透水を真空吸引による強制排除を行って非含水積層廃棄物層Ｂに圧密する排水圧密工程の後、無排出掘削孔Ｄからなる新規廃棄物投棄空間を形成して、表層廃棄物Ｅを投入して減容処理工程を行う。【選択図】図４
