Abstract
Description
以下に本発明を詳述する。
上記流量確保部に透水性を付与する手段としては、例えば、流量確保部に開口部を設ける方法等が挙げられる。
このような管路内浄化装置としては、例えば、外管と、透水性を有する内管とからなる二重管構造を有し、上記内管内が流量確保部となり、上記外管と上記内管との間隙が水浄化部となる管路内浄化装置(以下、二重管構造を有する管路内浄化装置ともいう)や、管路内を上部区画と下部区画とに分ける透水性の間仕切りを有し、上記上部区画が流量確保部となり、上記下部区画が水浄化部となる管路内浄化装置(以下、間仕切りを有する管路内浄化装置ともいう)等が挙げられる。
なお、本発明において管路とは、流体等を輸送するための管であり、閉じた横断面を持つ導管だけでなく、開渠(蓋無しの水路又は簡単に蓋をはずせる構造のもの)、暗渠(地下に埋設されている水路)を含むものとする。
なお、本明細書において「管路径」とは、管路の内側断面の外接円の直径を意味する。
上記内管に透水性を付与する手段としては、例えば、内管に開口部を設ける方法等が挙げられる。
上記架台の形状としては、例えば、プレート状、支持部と脚部とを有する形状、半割管状等が挙げられる。なかでも、加工が容易であることから、プレート状が好ましい。
上記「微生物担体」とは、好気性微生物や嫌気性微生物等を付着させるために使用する粒状や小片の材料を意味し、汚水の通水開始後1~4週間程度経過した後に好気性微生物や嫌気性微生物等が自然に微生物担体に付着し、増殖する。
上記微生物担体は、酸素と微生物とを効率よく接触させる必要があるため、比表面積が大きく、かつ、目詰まりをしにくい繊維状体、発泡体、多孔質体、網状体等を用いることが好ましい。
上記微生物担体に発泡体を用いる場合は、微生物担体内部まで汚水が透水することが好ましいことから、独立気泡タイプの発泡体よりも、連続気泡タイプの発泡体を用いることが好ましい。
なお、本明細書において上記「空隙率」とは、単位体積当たりにおける隙間の割合を100分率で表したものを意味する。
二重管構造を有する管路内浄化装置において、上記微生物担体を充填する高さの好ましい下限は、上記外管の管路径の20%である。上記微生物担体を充填する高さが、上記外管の管路径の20%未満であると、高い浄化性能が得られないことがある。
上記微生物担体の充填率は、上記外管と上記内管で囲まれた体積に対する微生物担体の体積の割合で定義され、その好ましい下限は10%、好ましい上限は100%である。上記充填率が10%未満であると、高い浄化性能が得られないことがある。
上記担体保持材の材料としては、例えば、ポリエチレン、ポリプロピレン等が挙げられる。上記担体保持材は、管状の担体保持管であり、水浄化部の容積を調節し、かつ、保持する機能を有することが好ましい。
上記担体保持管に透水性を付与する手段としては、例えば、担体保持管に開口部を設ける方法等が挙げられる。
上記水浄化部における流下性能を充分に確保することができるとともに、管路内清掃等のメンテナンス作業を容易に行うことができるため、上記底部連続間隙の管路径方向断面積は7cm2以上であることが好ましい。上記底部連続間隙を設ける方法としては、上記外管と上記内管との間に微生物担体を略上側、底部連続間隙を略下側となるように分ける透水性の間仕切りを設ける方法や、上記外管と上記内管との間に微生物担体を略上側、底部連続間隙を略下側となるように分ける透水性を有する底部連続間隙保持材を設置する方法等が挙げられる。上記底部連続間隙保持材は上記担体保持材と同じく透水性を有するため、上記担体保持材に微生物担体を封入せず、そのまま上記底部連続間隙保持材として用いてもよい。
本発明の管路内浄化装置では、流量確保部から供給され、水浄化部にて浄化された水は、そのまま水浄化部を流れることとなる。そのため、このような管路内浄化装置では、下流側になるほど、流量確保部を流れる水が少なくなって充分な流下性能が得られなくなる。そこで本発明者らは鋭意検討した結果、人孔において、上流側の管路内浄化装置の水浄化部を流れてきた水が、下流側の管路内浄化装置の流量確保部へ流れ込むように接続することにより、一旦水浄化部に供給された水を再び流量確保部に戻すことで、優れた流下性能と優れた浄化性能とを両立させることができることを見出した。
本発明の管路内浄化装置の接続構造では、上記人孔において、上記管路内浄化装置Aの水浄化部を流れてきた水が、上記管路内浄化装置Bの流量確保部へ流れ込むように、上記管路内浄化装置Aと上記管路内浄化装置Bとが接続されている。このような人孔によって、管路内浄化装置Aの流量確保部から水浄化部に供給され、そのまま管路内浄化装置Aの水浄化部を流れてきた水が、管路内浄化装置Bの流量確保部に供給されることとなり、流下性能を低下させることなく優れた浄化性能を発揮することができる。
上記管路内浄化装置Aと上記管路内浄化装置Bとの高さに差を設ける方法としては、例えば、上記人孔に、上記管路内浄化装置Aの水浄化部以下の高さ、かつ、上記管路内浄化装置Bの流量確保部以上の高さとなる水路を設ける方法等が挙げられる。上記人孔の水路は、管路内浄化装置Aの水浄化部及び上記管路内浄化装置Bの流量確保部と同じ高さでそれぞれの管路内浄化装置と接続することが好ましい。
本発明の管路内浄化装置は、図1に示すように、外管1と、開口部4を有する内管3とによる二重管構造を有し、かつ、上記二重管構造の間隙に微生物担体5が充填されることにより構成されている。
本発明の管路内浄化装置は、図2、図3のように外管1と内管3の配置を変えたものであってもよい。図2のように外管1と内管3の配置を変えた場合、微生物担体5が空気に触れている時間は長くなるが、その充填量は少なくなる。これに対して、図3のように外管1と内管3の配置を変えた場合、上記微生物担体5の充填量は多くなるが、上記微生物担体5が汚水中に浸漬している時間は長くなる。このように、外管1と内管3の配置を変えることにより、汚水の流量、性状に対応した処理が可能となる。
本発明の管路内浄化装置は、図4のように外管1と内管3の間隔を保持するために、担体保持管8を設けたものであることが好ましい。担体保持管8は、内管3の重量を支えるのに充分な強度を保持しており、かつ、外周から汚水が浸透しやすくなるように、開口部を設けている。担体保持管8の内部に、耐荷重が小さく、比表面積の大きな微生物担体5を充填することにより、上記微生物担体5自体に内管3による荷重が掛かり、圧密されることを防ぐ働きをする。上記担体保持管8は、隣接する担体保持管同士の間に間隙9を設けることにより、微生物担体5をそのまま充填した場合に比べ、汚水中の固形物等による目詰まりが起こりにくくなる。
本発明の管路内浄化装置は、図1に示すように、外管1が、間仕切り13によって上部区画15と下部区画16とに分けられた構造を有する。
図10の管路内浄化装置では、微生物担体5が担体保持管8により固定されている。担体保持管8の内部に、微生物担体5を充填することにより、微生物担体5の流出を防止することができる。また、担体保持管8は、各担体保持管8間に流路となる間隙9を形成するように設置されており、該間隙9が流路となることで、微生物担体5をそのまま充填した場合(図8)に比べ、汚水中の固形物等による目詰まりが起こりにくくなる。
一方、表2に示したように、図1に示したような微生物担体を利用した管路内浄化装置において、管路径350mmの外管と管路径200mmの内管を用い、その間隙の1/2に微生物担体として比表面積3000m2/m3のスポンジ状担体を充填した場合では、外管の管路軸方向1m当たりの担体表面積は、96m2/mとなる。このように二重管構造の間隙に比表面積が大きい微生物担体を充填することにより、管路内面の生物膜を用いる場合と比較して、100倍以上の表面積を保持することができる。
また、表3に示したように、図8に示したような微生物担体を利用した管路内浄化装置において、管路径350mmの外管の管路内を、間仕切りにより、上部区画と下部区画とが容積比で1:1となるように分け、充填量が40L/mとなるように微生物担体を充填し、微生物担体に比表面積3000m2/m3のスポンジ状担体を用いた場合では、下部区画1m当たりの担体表面積は、120m2/mとなる。このように下部区画に比表面積が大きい微生物担体を充填することにより、管路内面の生物膜を用いる場合と比較して、100倍以上の表面積を保持することができる。
表1に示したように、微生物膜によるBOD表面積負荷量を5g/m2・d、BOD除去率を90%とすると、図12のような微生物膜を利用した管路内浄化装置の管路軸方向1m当たりの1日当たりBOD除去量は2.5g/m・dと試算される。一方、表2、3に示したように、微生物担体のBOD容積負荷量を1kg/m3・d、BOD除去率を90%とすると、図1及び図8のようなスポンジ状担体を利用した管路内浄化装置の管路軸方向1m当たりの1日当たりBOD除去量は29g/m・dと試算される。このように、二重管構造と微生物担体を用いることにより、微生物膜の10倍以上にもなるBOD除去量を達成することができる。
図13の管路内浄化装置では、内管3の底部の形状に沿った切欠きが形成されたプレート状の架台20が外管1に設置されており、内管3は架台20上に設置されている。プレート状の架台20と外管1の底部との間には、管軸方向に沿って連続した流路となる底部連続間隙12が形成されており、外管1と内管3との間における汚水の流下性能が確保されている。
図14の管路内浄化装置では、内管3の底部に沿った形状の支持部と脚部とを有する架台20が外管1に設置されており、内管3は架台20上に設置されている。このような架台20を用いる場合、内管3を安定して設置し、かつ、内管3と架台20とがずれたり、架台20から内管3が外れたりすることを防止するため、架台20は、外管1及び内管3と固定されていることが好ましい。架台20と外管1の底部との間には、管軸方向に沿って連続した流路となる底部連続間隙12が形成されており、外管1と内管3との間における汚水の流下性能が確保されている。
図15の管路内浄化装置では、3つの半割管が連なってなる架台20が外管1に設置されており、内管3は架台20上に設置されている。図15の管路内浄化装置では、架台20の3つの半割管により、3点で内管3を支持している。架台20と外管1の底部との間には、各半割管によって管軸方向に沿って連続した流路となる底部連続間隙12が形成されており、外管1と内管3との間における汚水の流下性能が確保されている。
本発明の管路内浄化装置の接続構造は、図16、17に示したように、上流側の管路内浄化装置A100と、下流側の管路内浄化装置B200とを、水路301を有する人孔300を介して接続した構造を有する。
図18の管路内浄化装置の接続構造で接続される管路内浄化装置A100及び管路内浄化装置B200は、外管101、201が、それぞれ間仕切り105、205によって、上部区画と下部区画とに分けられた構造を有する。図18に示した管路内浄化装置A100及び管路内浄化装置B200では、上部区画がそれぞれ流量確保部103、203となり、下部区画がそれぞれ水浄化部104、204となる。
