循環水が流れる循環流路と、
前記循環流路を流れる循環水を使用する、住居、テナント、及び事務所の内の少なくとも一種からなる小口水需要体が複数集まって構成される水需要体、から排出される排出水を前記循環流路へ排出する排出流路と、
前記循環流路を流れる前記排出水を含む循環水を浄化する浄化手段と、
前記浄化手段で浄化された循環水を前記水需要体に供給する供給流路と、
複数の前記小口水需要体の各々に対して夫々設けられる、前記供給流路から前記循環水を取水するための複数の取水部と、
複数の前記取水部に対して夫々設けられる、前記小口需要体の各々に対して供給される前記循環水を夫々殺菌処理する複数の殺菌処理手段と、を少なくとも含む。
これに対して本循環水利用システムでは、循環水を取水するための取水部に循環水を殺菌処理する殺菌処理手段が設けられている。このため、利用者である複数の小口需要体の各々が循環水を利用する直前の段階で循環水を殺菌処理することが出来るため、利用者の循環水に対する信頼を高めることが出来るようになっている。
ただし、本発明の範囲は以下の実施形態に限定されるものではない。以下の実施形態に記載されている構成部品の寸法、材質、形状、その相対配置などは、本発明の範囲をそれにのみ限定する趣旨ではなく、単なる説明例に過ぎない。
循環水利用システム1は、公共の上水道網とは別に、特定の地域を対象として構築されるシステムである。本システムの対象となる人口規模としては、おおよそ5,000~20,000人を想定している。対象地域としては、住居の集合体であるマンション、事務所の集合体であるオフィスビル、テナントの集合体である商業施設、及びこれらが混在する複合施設などである。
循環流路2を流れる循環水の原水は、公共の上水道から供給される水道水に限定されず、井戸水、河川から取水した水、海水を淡水化した水、雨水等であってもよい。また、循環水が不足する場合には、これらの原水を外部から補給水として循環流路2に取り入れるように構成してもよい。なお、これらの原水を補給水として循環流路2に取り入れる場合、その水質レベルに応じて後述する浄化手段8の処理槽に取り込むとよい。例えば、比較的水質の良い井戸水、河川から取水した水、海水を淡水化した水については、後述する浄化手段8の粗膜コンテナL4又は微細膜コンテナL5に取り込み、比較的水質の悪い雨水については通気性コンテナL2、好気性コンテナL3に取り込むように構成するとよい。
