Description
例えば、特許文献1には、管路の内面に有用微生物群を含有したセラミック材の膜を設けることによって汚水を有用微生物と接触させ、汚水を浄化する管路用汚水浄化装置が開示されている。
また、酸素供給手段を用いる場合には、設備費、施工費が高価になる等の問題があった。さらに、管路用浄化装置は、汚水の流下性能を充分に確保し、埋設時等に生じる応力による破損を防止する必要がある。
また、特許文献4記載の管路内浄化装置および管路内浄化装置の接続構造は、高効率で汚水を浄化することができるが、構造が複雑で作業工数が多く費やされる。
一局面に従う管路内浄化装置は、管路内に設置される管路内浄化装置において、断面の少なくとも一部が管路の曲面に沿って形成された曲面状部材と、曲面状部材の少なくとも一部の周囲または内周側に、微生物担体が形成されたものである。ここで、微生物担体は、管路内に設置された場合の管路の最下部表面で欠損している。
ここで、微生物担体は、管路内に設置された場合の管路の最下部表面で欠損しているので、管路の最下部において確実に流速を確保することができる。また、流量が少ない場合には、流速を低下させることがなく、流量が多い場合には、浄化を行うことができる。
第2の発明にかかる管路内浄化装置は、一局面に従う管路内浄化装置において、曲面状部材が管路内に設置された場合の管路の最下部表面で欠損していてもよい。
第3の発明にかかる管路内浄化装置は、一局面または第2の発明にかかる管路内浄化装置において、微生物担体は、曲面状部材の両端部にそれぞれ配設される第1の微生物担体と第2の微生物担体と、を含んでもよい。

そのため、上記のサイズであることが好ましい。

また、曲面状部材400dの曲面率を一定にしているが、これに限定されず、少なくとも一部が、配管200の内周面に沿っていればよい。
管路内浄化システム500dは、配管200内に管路内浄化装置100dを設けることにより浄化の効率を高めることができる。

このように、容易に面811,812を、管路内浄化装置100cと容易に嵌合することができる。
さらに、曲面状部材400,400a,~,400gが配管200の長手方向に沿って連続して延在する場合について説明したが、これに限定されず、配管200の長手方向に部分的に、または断続的に配設されていてもよい。
