Description

【０００１】
【発明の属する技術分野】
本発明は、産業廃棄物や焼却残灰等の廃棄物を埋立処理し、又は焼却炉や集塵処理装置等の環境処理装置を解体処理する密閉空間内における廃棄物の処理方法及びその処理施設に関するものである。
【０００２】
【従来の技術】
従来より、産業廃棄物や焼却残灰等の廃棄物については、一般に山間の谷地を切り開いて造成した埋立地に、この廃棄物と覆土とを交互に投棄して埋立処理している。この場合、廃棄物に含まれた有害成分が雨水によって埋立地の周囲に漏出し、河川水や地下水、或いは周辺の土壌、生物を汚染する公害が多発していた。そこで、有害成分が雨水によって埋立地外に漏出しないように対策を講じる必要がある。
【０００３】
この有害物質の漏出を防止するために種々の埋立処理方法が提案されている。例えば、埋立地の内面をゴムシートや合成樹脂シート等の遮水シートで覆うことにより、廃棄物中に雨水が浸透しても埋立地外に漏れ出ないようにする処理方法がある。また、埋立地の周縁に側溝を設けて、雨水が埋立地内に流れ込むのを防止する方法がある。このような単純な処理方法では、何らかの理由で遮水シート等に穴が開いた場合、雨水による有害物質の漏出は防止できなかった。
【０００４】
そこで、埋立地の内面に下部遮水シートを敷設することに加えて、最上層の仕上げ層中に上部遮水シートを埋設し、更に、埋立地の底面に排水溝を設ける埋立処理方法が提案されている。この埋立処理方法では、雨水が廃棄物層中に浸透することを上部遮水シートによって防止することに加えて、仮に上部遮水シート及び下部遮水シートが破れても、安全性を向上させるために、下部遮水シートの穴から漏れ出た水を排水溝に集めて処理するようになっている。
【０００５】
【発明が解決しようとする課題】
しかし、上述した従来の埋立処理方法では、最上層の仕上げ層まで廃棄物の埋立が完了するまで、その埋立を露天で行っているため、埋立処理工程中に埋立地からダイオキシン類の有害物質が飛散して周囲の環境に悪影響を及ぼしていた。特に、風により有害物質、悪臭又は粉塵を広範囲に飛散させやすいという問題を有していた。
【０００６】
一方、埋立地への廃棄物の投棄は長い期間にわたって行われるもので、その間における降雨、地域によっては降雪等が流れ込む。特に、この種の埋立地は山間地に造成されることが多いため降雨量も多い。上記従来の埋立処理方法では、埋立処理工程中に埋立地内に降った雨や雪はそのまま廃棄物層及び覆土層に浸透するので、汚染水が埋立地外に漏出しやすいという問題を有していた。更に、廃棄物が水と反応したり醗酵したりして、メタンガス等のガスが発生したり発熱したりする現象も発生しやすいという問題も有していた。
【０００７】
本発明は、上述した問題点を解決するために創案されたものである。すなわち本発明の目的は、フレキシブルな膜構造の屋根を用いることにより、廃棄物を埋立処理するとき又は環境処理装置を解体するときに生じるダイオキシン類等の有害物質の飛散を防止すると共に、雨水の浸入を防止することにより埋立地の土壌、地下水への汚染を防止することができる密閉空間内における廃棄物の処理方法及びその処理施設を提供することにある。
【０００８】
【課題を解決するための手段】
本発明の埋立処理方法によれば、廃棄物（２）を埋立処理するために埋立地（１）を窪地状に造成し、該窪地状の埋立地（１）の内面を遮水シート（４）で覆い、前記埋立地（１）の底面に、廃棄物（２）等から浸出する液体を集めて該埋立地（１）の外部に排出するための下部排水路（９）を設け、前記埋立地（１）の全体を覆い、内部の気圧を維持するように吸排気しながら密閉空間を形成する膜構造の屋根（１０）を設け、前記埋立地（１）に廃棄物（２）と覆土（３）とを交互に積層し、最上層に仕上げ層を盛り土し、該最上層に水平排水層（１５）を設ける、ことを特徴とする密閉空間内における廃棄物の処理方法が提供される。
【０００９】
また、廃棄物（２）を埋立処理するための埋立地（１）の周囲に擁壁（２１）を形成し、前記埋立地（１）の底面に、廃棄物（２）等から浸出する液体を集めて該埋立地（１）の外部に排出するための下部排水路（９）を設け、前記埋立地（１）の全体を覆い、内部の気圧を維持するように吸排気しながら密閉空間を形成する膜構造の屋根（１０）を設け、前記擁壁（２１）内に廃棄物（２）と覆土（３）とを交互に積層し、最上層に仕上げ層を盛り土し、該最上層に水平排水層（１５）を設ける廃棄物の処理方法がある。
【００１０】
前記埋立地（１）とこれを覆う膜構造の屋根（１０）内に飛散する有害物質と悪臭を、活性炭で吸着除去する、ことが好ましい。
【００１１】
前記埋立地（１）とこれを覆う膜構造の屋根（１０）内に飛散する有害物質に対して定期的に散水することにより、Ｈｃｌ系、Ｎｏｘ系又はＳｏｘ系等の有害ガスを中和反応して除去する、ことが好ましい。
【００１２】
上記発明の方法では、廃棄物（２）の埋立処理工程中においては、この埋立地（１）又は擁壁（２１）がフレキシブルな膜構造の屋根（１０）によって覆われているため、その埋立処理工程中に生じるダイオキシン類の有害物質、悪臭又は粉塵等が埋立地（１）に周囲に飛散することを防止して周囲環境への悪影響を防止することができる。
【００１３】
また、膜構造の屋根（１０）は、降雨や降雪があってもその埋立地（１）又は擁壁（２１）内の廃棄物（２）層中に雨水等が浸透することを防止することができる。このように雨水の浸入を防止することにより埋立地（１）又は擁壁（２１）内の土壌、地下水への汚染を防止することができる
【００１４】
特に、埋立地（１）とこれを覆う膜構造の屋根（１０）内において飛散する有害物質と悪臭を、活性炭で吸着除去する。更に、これらの有害物質を、ラジカル反応ガス状態にすることにより、活性炭表面上でも触媒反応効果が持続し、更にダイオキシンを分解して除去することができる。埋立工程中にも良好な環境で埋立作業が可能である。
【００１５】
本発明の解体処理方法によれば、焼却炉や集塵処理装置等の環境処理施設（２２）の全体を覆い、内部の気圧を維持するように吸排気しながら密閉空間を形成する膜構造の屋根（１０）を設け、前記埋立地（１）とこれを覆う膜構造の屋根（１０）内に飛散する有害物質と悪臭を、活性炭で吸着除去しつつ前記環境処理施設（２２）を解体処理すること、を特徴とする密閉空間内における廃棄物の処理方法が提供される。
【００１６】
この解体処理方法では、焼却炉や集塵処理装置等の環境処理装置（２２）を解体するときに生じやすいダイオキシン類等の有害物質や粉塵等が処理施設の周囲に飛散することを防止しながら解体処理することができる。特に、環境処理装置を覆う屋根がフレキシブルな膜構造の屋根（１０）であるために、焼却炉施設のように高くそびえる煙突があっても、この煙突の途中まで包むようにして焼却炉施設本体の大部分を密閉空間にすることができる。そこで、外部へ有害物質や粉塵等を飛散させることなく施設や装置を解体することができる。
【００１７】
本発明の処理施設によれば、埋立地（１）に廃棄物（２）と覆土（３）とを交互に積層し、最上層に仕上げ層を盛り土する廃棄物の処理施設であって、前記廃棄物（２）を埋立処理するために窪地状に造成すると共に、その内壁面に遮水シート（４）を張り付けた埋立地（１）と、前記廃棄物（２）等から浸出する液体を集めて埋立地（１）外に排出するために前記埋立地（１）の底面に設けた下部排水路（９）と、前記埋立地（１）の全体を覆い、密閉空間を形成するように設けた膜構造の屋根（１０）と、該膜構造の屋根（１０）内の気圧を維持するように、吸気する吸気装置（１１）及び排気する排気装置（１２）と、を備えた、ことを特徴とする密閉空間内における廃棄物の処理施設が提供される。
【００１８】
また、埋立地（１）に廃棄物（２）と覆土（３）とを交互に積層し、最上層に仕上げ層を盛り土する廃棄物の処理施設であって、前記廃棄物（２）を埋立処理するための埋立地（１）の周囲に形成した擁壁（２１）と、前記廃棄物（２）等から浸出する液体を集めて埋立地（１）外に排出するために前記埋立地（１）の底面に設けた下部排水路（９）と、前記埋立地（１）の全体を覆い、密閉空間を形成するように設けた膜構造の屋根（１０）と、該膜構造の屋根（１０）内の気圧を維持するように吸気する吸気装置（１１）及び排気するに排気装置（１２）と、を備えることができる。
【００１９】
前記排気装置（１２）に、飛散する有害物質等をラジカル反応ガス状態にすることにより、活性炭表面上でも触媒反応効果が持続し、更にダイオキシン類を分解して除去する活性炭フィルターカセット（１２ａ）を設けることができる。
【００２０】
前記膜構造の屋根（１０）に、前記埋立地（１）内に飛散する有害物質に対して定期的に散水するスプリンクラー（１３）を、備えることが好ましい。
【００２１】
前記膜構造の屋根（１０）から垂れ落ちた雨水や融雪を埋立地（１）外に流出させる外周水路（９）を設けることが好ましい。
【００２２】
上記構成の処理施設では、膜構造の屋根（１０）が施設内部の有害物質等の飛散を防止すると共に、降雨等の水の浸入を防止することができる。膜構造の屋根（１０）がフレキシブルであるために、覆う対象物に応じて容易に変形させることができる。
【００２３】
特に、施設内は廃棄物の処理工程中において排気装置（１２）により有害物質や悪臭を除去し、内部環境を良好にしているので、埋め立て処理完了後に、この埋立地（１）をすぐに屋根付きの施設として種々の目的に使用することができる。
【００２４】
【発明の実施の形態】
以下、本発明の好ましい実施の形態を図面を参照して説明する。なお、各図において、共通する部分には同一の符号を付し重複した説明を省略する。
図１は本発明の密閉空間内における廃棄物の処理方法による処理施設を示す断面図である。図２は廃棄物の埋立てが完了した状態を示す処理施設の断面図である。図３は処理施設における吸排気装置を示す断面図である。図４は埋立処理施設における汚水処理施設と入り口を示す断面図である。
本発明の密閉空間内における廃棄物の処理方法は、図１と図２に示すように、一般廃棄物や産業廃棄物等を埋設する埋立地１内に廃棄物２と覆土３とを交互に積層し、最上層に仕上げ層を盛り土することにより廃棄物２を処理する方法である。
【００２５】
本発明の処理方法は、先ず、一般廃棄物や産業廃棄物等の廃棄物２を埋立処理するために、埋立地１は山間地の谷間等において、この谷を削って堰堤でせき止めることによって窪地状に造成する。
【００２６】
この窪地状の埋立地１の内壁面は、合成樹脂製又はゴム製等の適宜素材から成る遮水シート４を張り付ける。この遮水シート４の上に、覆土３と廃棄物２とをならしながら交互に投棄し、最上面を仕上げ層とする。なお、埋立地１の内部は長年にわたって徐々に沈下するため、この遮水シート４は、沈下しても張力が生じないように予め十分なゆとりを持たせた状態で敷設しておく。そこで、埋立地１の内壁面は、吹き付けコンクリート５で固めておくことが好ましい。
【００２７】
埋立地１の底面となる基礎地盤６の上面に、吹き付けコンクリート５で固めた浸出水排水層７を設ける。この浸出水排水層７の中心部に浸出水排水渠８を設ける。この浸出水排水渠８において廃棄物２等から浸出する液体を集め、下部排水路９を介して埋立地１の外部に排出する。この下部排水路９に集められた水は、埋立地１の外側に設置した汚水処理施設１６に集められる。また、下部排水路６は、沈下し切った状態で埋立地１の外側に向けて傾斜するように設定しておくことが好ましい。
【００２８】
埋立地１は、その全体をフレキシブルな膜構造の屋根１０で覆い、密閉空間を形成する。この膜構造の屋根１０は、図示例では半球状の屋根が形成されるような透明なシート材から成る。このシート材の素材は特に限定はないが、耐久性と透光性等の点からは、例えばポリエステル系等の合成樹脂製のものが好ましい。特に、紫外線の透過を完全に又は部分的に遮断する素材を使用するのが好ましい。なお、シート材（膜構造の屋根１０）は、帯状の原反を熱融着や接着、縫合等の適当な手段で接合することにより、広い面積に形成したものである。
【００２９】
膜構造の屋根１０内は、吸気装置１１と排気装置１２により内部の気圧を維持するようになっている。この内部の気圧を維持することにより、膜構造の屋根１０は主柱や骨格がある構造のときは勿論のこと、主柱や骨格がない構造でも、シート材をドーム状又はテント状の形状を維持することができるようになっている。
【００３０】
本発明の埋立地１は、膜構造の屋根１０によって覆われているため、その埋立処理工程中に生じるダイオキシン類の有害物質、悪臭又は粉塵等が埋立地１に周囲に飛散することを防止して周囲環境に悪影響を防止することができる。
【００３１】
特に、埋立地１とこれを覆う膜構造の屋根１０内に飛散する有害物質と悪臭を、排気装置１２内に設けた活性炭フィルターカセット１２ａで、ラジカル反応ガス状態にすることにより、活性炭表面上でも触媒反応効果が持続し、更にダイオキシン類を分解して除去することができる。
【００３２】
この活性炭フィルターカセット１２ａは、排気装置１２内において交換可能に並列したものであり、埋立地１と膜構造の屋根１０によって形成される容量に応じて、その個数を増減することができる。また、この活性炭フィルターカセット１２ａは、多孔質の板材からなるケース内に、所定の物性を有する粒状の活性炭を充填したものである。多孔質の板材と粒状の活性炭との間にカーボン繊維フィルターを配置してある。
【００３３】
膜構造の屋根１０にスプリンクラー１３を設け、飛散する有害物質に対して定期的に散水する。この散水により、Ｈｃｌ系、Ｎｏｘ系又はＳｏｘ系等の有害ガスを中和反応して除去することができる。更に、膜構造の屋根１０には夜間作業を可能にするための照明装置１４を設ける。
【００３４】
また、膜構造の屋根１０は、その埋立地１内に降雨や降雪があっても廃棄物２層中に水が浸透することを防止することができる。そこで、埋立地１内に廃棄物２と覆土３とを交互に積層し、最上層に仕上げ層を盛り土しながら、廃棄物２を埋め込むことができる。また、埋立終了後には、最上層に水平排水層１５により、廃棄物２層中への雨水や融雪の浸透を防止することができる（図２参照）。このように雨水の浸入を防止することにより埋立地１の土壌、地下水への汚染を防止することができる。
【００３５】
埋立地１の全体を覆う膜構造の屋根１０には、下部排水路９に集められた水の水質を浄化する汚水処理施設１６を埋立地１の外側に設置する（図４参照）。また、膜構造の屋根１０には、内部の有害物質や塵芥が外部に出ないようにする二重扉１７を設ける。
【００３６】
図５は埋立処理施設の入口におけるエアカーテンを示す説明図である。図６は埋立処理施設の出口における洗車装置を示す説明図である。
膜構造の屋根１０の入口には、作業車ｃが入る際に、内部の有害物質や塵芥が外部に出ないようにするエアカーテン１８を設ける。また、膜構造の屋根１０の出口には、有害物質や塵芥が付着した作業車ｃがそのまま外部に出ないように洗車装置１９で洗車する。
【００３７】
膜構造の屋根１０から垂れ落ちた雨水や融雪を埋立地１の外部に流出させる外周水路２０を設ける。
【００３８】
図７は本発明の密閉空間内における廃棄物の処理施設の他の実施の形態を示す断面図であり、（ａ）は埋立途中の状態であり、（ｂ）は埋立が完了したものである。
廃棄物２を埋立処理するための埋立地１は、窪地状に造成する代わりに埋立地１の周囲に擁壁２１を形成することも可能である。このように擁壁２１を形成することで、埋立地１の全体を覆う膜構造の屋根１０を設けることにより、この擁壁２１で囲まれた埋立地１内に廃棄物２と覆土３とを交互に積層し、最上層に仕上げ層を盛り土し、廃棄物２を処理することができる。
【００３９】
本発明の処理施設では、膜構造の屋根１０が施設内部の有害物質等の飛散を防止すると共に、降雨等の水の浸入を防止することができる。特に、膜構造の屋根１０がフレキシブルであるために、覆う対象物に応じて容易に変形させることができる。
【００４０】
特に、施設内は廃棄物の処理工程中に排気装置１２により有害物質や悪臭を除去しているので、内部環境を良好にしてあるので、埋め立て処理完了後直に、埋め立て処理完了した施設内は、屋根付きの施設として種々の目的に使用することができる。
【００４１】
図８は密閉空間内において環境処理施設を解体する処理方法を示す断面図である。
本発明の処理方法は、焼却炉や集塵処理装置等の環境処理装置２２を解体するときに生じやすいダイオキシン類等の有害物質や粉塵等が処理施設の周囲に飛散することを防止しながら解体処理することができる。環境処理施設２２を解体処理するために、環境処理施設２２の全体を覆い、密閉空間を形成するように膜構造の屋根１０を設け、膜構造の屋根１０内の気圧を維持するように吸排気しながら環境処理施設２２を解体処理する。
【００４２】
この解体処理方法では、環境処理装置２２を覆う屋根がフレキシブルな膜構造の屋根１０であるために、焼却炉施設のように高くそびえる煙突２２ａがあっても、焼却炉施設本体の大部分を密閉空間にすることができる。
【００４３】
なお、上述した例では、埋立地１にフレキシブルな膜構造の屋根１０を設けた方法と施設について詳述したが、有害物質の飛散を防止すると共に、雨水の浸入を防止できるものであれば、本発明はこのような実施の形態に限定されず、本発明の要旨を逸脱しない範囲で種々変更できることは勿論である。
【００４４】
【発明の効果】
上述したように、本発明の密閉空間内における廃棄物の処理方法は、埋立地がフレキシブルな膜構造の屋根によって覆われているため、その埋立処理工程中に生じるダイオキシン類の有害物質、悪臭又は粉塵等が埋立地に周囲に飛散することを防止して周囲環境に悪影響を防止することができる。
【００４５】
また、この膜構造の屋根によって、降雨や降雪があっても廃棄物層中に水が浸透することを防止するので、雨水等の浸入による埋立地内の土壌、地下水への汚染を防止することができる
【００４６】
本発明の廃棄物の処理施設は、膜構造の屋根がフレキシブルであるために、覆う対象物に応じて容易に変形させることができ、あらゆる処理施設に利用することができる。
【００４７】
また、施設内は廃棄物の処理工程中において排気装置により有害物質や悪臭を除去し、内部環境を良好にしているので、埋め立て処理完了後に、すぐ埋め立て処理完了した施設内は、屋根付きの施設として種々の目的に使用することができる、等の優れた効果を有する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method and a facility for treating waste in an enclosed space for landfilling waste such as industrial waste and incineration ash, or dismantling environmental treatment equipment such as incinerators and dust collection equipment. It is about.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, waste such as industrial waste and incineration ash has been landfilled by alternately dumping the waste and cover soil in a landfill created by cutting a mountain valley. In this case, harmful components contained in the waste leaked around the landfill due to rainwater, and polluting the river water and groundwater, or surrounding soil and organisms occurred frequently. Therefore, it is necessary to take measures to prevent harmful components from leaking out of the landfill by rainwater.
[0003]
Various landfill methods have been proposed to prevent this leakage of harmful substances. For example, there is a treatment method in which the inner surface of a landfill is covered with a waterproof sheet such as a rubber sheet or a synthetic resin sheet so that even if rainwater permeates the waste, it does not leak out of the landfill. There is also a method of providing a gutter on the periphery of the landfill to prevent rainwater from flowing into the landfill. With such a simple treatment method, if a hole is formed in the impermeable sheet or the like for some reason, leakage of harmful substances due to rainwater cannot be prevented.
[0004]
Therefore, in addition to laying a lower seepage control sheet on the inner surface of the landfill, a landfill treatment method is proposed in which an upper seepage control sheet is buried in the uppermost finishing layer and a drainage channel is provided at the bottom of the landfill. Have been. In this landfill treatment method, in addition to preventing rainwater from penetrating into the waste layer by the upper waterproof sheet, even if the upper waterproof sheet and the lower waterproof sheet are torn, safety is improved. In addition, the water leaked from the holes in the lower impermeable sheet is collected in a drain and treated.
[0005]
[Problems to be solved by the invention]
However, in the above-mentioned conventional landfill method, the landfill is performed on the open land until the landfill of the waste is completed up to the top finishing layer, so that harmful substances such as dioxins are discharged from the landfill during the landfill process. It was scattered and had an adverse effect on the surrounding environment. In particular, there has been a problem that harmful substances, bad smells or dusts are easily scattered over a wide range by wind.
[0006]
On the other hand, the dumping of waste into landfills takes place over a long period of time, and during that time rainfall and, depending on the area, snowfall, etc., flow. In particular, this type of landfill is often built in mountainous areas, and therefore has a large amount of rainfall. In the above-mentioned conventional landfill method, rain and snow falling in the landfill during the landfill process directly penetrate into the waste layer and the soil cover layer, and thus have a problem that contaminated water is likely to leak out of the landfill. Was. Further, there is a problem that a phenomenon in which the waste reacts with water or is fermented to generate gas such as methane gas or generate heat is likely to occur.
[0007]
The present invention has been made to solve the above problems. That is, an object of the present invention is to use a roof having a flexible membrane structure to prevent scattering of harmful substances such as dioxins generated when landfilling waste or dismantling an environmental treatment device, and to prevent rainwater It is an object of the present invention to provide a method for treating waste in a closed space and a treatment facility therefor that can prevent soil and groundwater in a landfill by preventing intrusion.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In each of the drawings, common portions are denoted by the same reference numerals, and redundant description will be omitted.
FIG. 1 is a sectional view showing a treatment facility according to the method for treating waste in an enclosed space of the present invention. FIG. 2 is a cross-sectional view of the treatment facility showing a state in which the landfill of waste has been completed. FIG. 3 is a cross-sectional view showing a suction and exhaust device in the processing facility. FIG. 4 is a sectional view showing a sewage treatment facility and an entrance in a landfill treatment facility.
As shown in FIGS. 1 and 2, the method for treating waste in an enclosed space according to the present invention is to alternately arrange waste 2 and cover soil 3 in a landfill 1 where general waste, industrial waste, etc. are buried. This is a method of treating waste 2 by stacking and embedding a finishing layer on the top layer.
[0025]
According to the treatment method of the present invention, first, in order to landfill waste 2 such as general waste and industrial waste, the landfill 1 is cut into a valley in a mountainous area, etc. Create a shape.
[0026]
A water-blocking sheet 4 made of an appropriate material such as synthetic resin or rubber is attached to the inner wall surface of the depression-shaped landfill 1. The soil 3 and the waste 2 are alternately dumped on the water-impervious sheet 4 while being leveled, so that the uppermost surface is a finished layer. Since the interior of the landfill 1 gradually sinks for many years, the water-blocking sheet 4 is laid in advance with sufficient clearance so that tension does not occur even if it sinks. Therefore, it is preferable to solidify the inner wall surface of the landfill 1 with the sprayed concrete 5.
[0027]
A leachate drainage layer 7 solidified with sprayed concrete 5 is provided on the upper surface of the foundation ground 6 serving as the bottom surface of the landfill 1. A leachate drainage channel 8 is provided at the center of the leachate drainage layer 7. The liquid leached from the waste 2 and the like in the leachate drainage 8 is collected and discharged to the outside of the landfill 1 through the lower drainage channel 9. The water collected in the lower drainage channel 9 is collected in a sewage treatment facility 16 installed outside the landfill 1. In addition, it is preferable that the lower drainage channel 6 is set so as to be inclined toward the outside of the landfill 1 in a state where the lower drainage channel 6 is completely sunk.
[0028]
The landfill 1 is entirely covered with a roof 10 having a flexible membrane structure to form an enclosed space. The membrane-structured roof 10 is made of a transparent sheet material that forms a hemispherical roof in the illustrated example. The material of the sheet material is not particularly limited, but is preferably made of a synthetic resin such as a polyester resin from the viewpoint of durability and light transmission. In particular, it is preferable to use a material that completely or partially blocks transmission of ultraviolet light. In addition, the sheet material (the roof 10 having a membrane structure) is formed in a wide area by joining a belt-shaped raw material by an appropriate means such as heat fusion, adhesion, or stitching.
[0029]
The air pressure inside the roof 10 having the membrane structure is maintained by an intake device 11 and an exhaust device 12. By maintaining the internal air pressure, the sheet material can be formed into a dome-shaped or tent-shaped shape even when the roof 10 having the membrane structure has a main pillar or a skeleton, as well as a structure having a main pillar or a skeleton. Can be maintained.
[0030]
Since the landfill 1 of the present invention is covered by the roof 10 having a membrane structure, it is possible to prevent harmful substances such as dioxins, odors, dusts, and the like generated during the landfilling process from scattering around the landfill 1. As a result, adverse effects on the surrounding environment can be prevented.
[0031]
In particular, harmful substances and odors scattered in the landfill 1 and the roof 10 having a membrane structure covering the landfill 1 are converted into a radical reaction gas state by the activated carbon filter cassette 12a provided in the exhaust device 12, so that the odorous substance and odor can be removed on the activated carbon surface. The catalytic reaction effect is maintained, and dioxins can be further decomposed and removed.
[0032]
The activated carbon filter cassettes 12a are exchangeably arranged in the exhaust device 12, and the number thereof can be increased or decreased according to the capacity formed by the landfill 1 and the roof 10 having the membrane structure. Further, the activated carbon filter cassette 12a is one in which granular activated carbon having predetermined physical properties is filled in a case made of a porous plate material. A carbon fiber filter is arranged between the porous plate and the granular activated carbon.
[0033]
A sprinkler 13 is provided on the roof 10 having a membrane structure, and water is periodically sprinkled against scattered harmful substances. By this watering, harmful gases such as Hcl, Nox or Sox can be neutralized and removed. Further, the roof 10 having the membrane structure is provided with a lighting device 14 for enabling nighttime work.
[0034]
In addition, the roof 10 having the membrane structure can prevent water from penetrating into the two layers of waste even if rainfall or snowfall occurs in the landfill 1. Therefore, the wastes 2 and the covering soil 3 are alternately stacked in the landfill 1, and the wastes 2 can be embedded while embedding the finishing layer on the uppermost layer. After the landfill, the horizontal drainage layer 15 at the top prevents rainwater and snowmelt from penetrating into the two waste layers (see FIG. 2). By preventing rainwater from penetrating in this way, it is possible to prevent soil and groundwater in the landfill 1 from being contaminated.
[0035]
A sewage treatment facility 16 for purifying the quality of water collected in the lower drainage channel 9 is installed outside the landfill 1 on the roof 10 having a membrane structure that covers the entire landfill 1 (see FIG. 4). Further, the roof 10 having the membrane structure is provided with a double door 17 for preventing harmful substances and dust inside from going outside.
[0036]
FIG. 5 is an explanatory diagram showing an air curtain at the entrance of the landfill treatment facility. FIG. 6 is an explanatory diagram showing a car washing device at an exit of a landfill treatment facility.
An air curtain 18 is provided at the entrance of the roof 10 having a membrane structure so that harmful substances and dust inside the work vehicle c do not go outside when the work vehicle c enters. Further, at the exit of the roof 10 having the membrane structure, the work vehicle c to which harmful substances and dust are attached is washed by the car wash device 19 so as not to go outside.
[0037]
An outer waterway 20 is provided for draining rainwater or snowmelt from a roof 10 having a membrane structure to the outside of the landfill 1.
[0038]

The landfill 1 for landfilling the waste 2 may have a retaining wall 21 formed around the landfill 1 instead of being formed in a depression. By forming the retaining wall 21 in this manner, by providing the roof 10 having a membrane structure that covers the entire landfill 1, the waste 2 and the soil 3 are placed in the landfill 1 surrounded by the retaining wall 21. The waste 2 can be treated by alternately stacking and embedding a finishing layer on the top layer.
[0039]
In the treatment facility of the present invention, the roof 10 having the membrane structure can prevent scattering of harmful substances and the like inside the facility, and can prevent intrusion of water such as rainfall. In particular, since the membrane structure roof 10 is flexible, it can be easily deformed according to the object to be covered.
[0040]
In particular, since the harmful substances and odors are removed by the exhaust device 12 during the waste treatment process in the facility, the internal environment is improved. It can be used for various purposes as a covered facility.
[0041]
