Description
上記実施の形態では、開口16は辺11〜14の長手方向に連続して設けられているが、途切れ途切れに一辺当り複数個設けられてもよい。この場合でも、各開口の幅は開口長手方向において均一である。なお、各開口は各辺において等間隔に設けられることが好ましい。
屋外に設置した撹拌機を設けない直径150cm、水深150cmの沈殿槽の底部から10cmの高さに図5に示すディストリビュータを設置した。ディストリビュータの管外径は114mm、管内径は107mm、各辺11〜14の長さは110cm、辺12〜14の開口16の長さはそれぞれ70cm、辺11の開口16の長さはそれぞれ20cmである。開口16の開き角度θは表1の通りである。管の材質は塩化ビニルである。ディストリビュータより下方の沈殿槽内部を邪魔板によって基端側(原水導入管15側)と先端側とに区画し、原水が手前側と奥側とに均等に供給されているか確認できるようにした。
ディストリビュータとして図8に示すものを用いたこと以外は実施例3と同一条件として実験を行った(開き角度θも120°であり、実施例3と同一である。)。その結果、ディストリビュータ基端側からの流出量は4.5m3/hr、先端側からの流出量は25.5m3/hrであり、先端側から著しく多量に流出した。
実施例3において、ディストリビュータの各辺の開口16をすべて連続させて一続きとした。このディストリビュータを用いたこと以外は実施例3と同一条件にて原水を供給したところ、基端側からの流出量は25m3/hrであり、先端側からの流出量は5m3/hrであり、基端側から著しく多量に流出した。

Claims (6)
- 汚泥を含む液を被処理液として沈殿槽に流出させるためのディストリビュータであって、管状の通水部材と、該通水部材の底面に設けられ、通水部材の長手方向に延在する液流出用開口とを有するディストリビュータにおいて、
該通水部材の管軸に対する該開口の開き角度θが60〜180°であることを特徴とするディストリビュータ。 - 請求項1において、該開き角度θが90〜150°であることを特徴とするディストリビュータ。

- 槽体の下部に請求項1ないし3のいずれか1項に記載のディストリビュータが前記開口を下方に向けて設置されている沈殿槽。
- 請求項4において、前記ディストリビュータの平面視形状が枠状又は環状であることを特徴とする沈殿槽。
- 請求項4又は5の沈殿槽を運転する方法であって、前記ディストリビュータに供給する液の比重d1と前記槽体内の液の比重d2との差が0.0001〜0.1であり、かつd2>d1であることを特徴とする沈殿槽の運転方法。
