【発明の実施の形態】
本発明の第１の実施の形態による被処理流体処理装置は、光触媒を担持させた可動体と被処理流体が光触媒反応槽の上部から光触媒反応槽へ流入し、光触媒反応槽の光源体からの光によって、可動体に担持された光触媒が被処理流体に含まれる有機物を分解しつつ光触媒反応槽の下部へと移動し反応槽仕切板へ到達する。次に、光触媒反応槽の下部より流出し分離槽流入管を通り分離槽へと流入する。分離槽へ流入した可動体と被処理流体はろ過され、被処理流体の一部が処理流体として被処理流体処理装置の外部へ排出される。被処理流体の残りと可動体は分離槽の下部より流出し駆動源流入管へと流入する。駆動源流入管へ流入した可動体と被処理流体は、駆動源流入管の途中で被処理流体取り込み管を経由して、被処理流体貯留槽より分離槽で排出した処理流体とほぼ同量の被処理流体を被処理流体処理装置へ取り込み、駆動源へと流入する。可動体と被処理流体は、駆動源で駆動されて再び光触媒反応槽の上部から光触媒反応槽へと流入する。本実施の形態によれば、光触媒反応槽の下部に設けられた開口のある反応槽仕切板へと到達した可動体と被処理流体のうち可動体の多くは反応槽仕切板の上に載り、反応槽内の乱流によって反応槽内に拡散する、一方、可動体の一部と被処理流体は反応槽仕切板の開口部を通過し、光触媒反応槽の下部より流出し分離槽流入管を通り分離槽へと流入する。このため、光触媒を担持させた可動体の多くが光触媒反応槽の内部に留まり、光源からの光と接触する割合が大きくなる。また、駆動源が停止した場合には、可動体の多くが反応槽仕切板に載るため、光触媒反応槽の流出口に可動体が沈降堆積することがなく、駆動源を再駆動した場合に流出口が閉塞しないようにすることができる。
【００１７】
本発明の第２の実施の形態による被処理流体処理装置は、光触媒を担持させた可動体と被処理流体が光触媒反応槽の上部から光触媒反応槽へ流入し、光触媒反応槽の光源体からの光によって可動体に担持された光触媒が被処理流体に含まれる有機物を分解しつつ光触媒反応槽の下部へと移動し、光触媒反応槽の下部に設けられた反応槽仕切板へと到達する。次に、光触媒反応槽の下部より流出し分離槽流入管を通り分離槽へと流入する。分離槽へ流入した可動体と被処理流体はろ過され、被処理流体の一部が処理流体として被処理流体処理装置の外部へ排出される。被処理流体の残りと可動体は分離槽の下部より流出し駆動源流入管へと流入する。駆動源流入管へ流入した可動体と被処理流体は、駆動源流入管の途中で被処理流体取り込み管を経由して、被処理流体貯留槽より分離槽で排出した処理流体とほぼ同量の被処理流体を被処理流体処理装置へ取り込み、駆動源へと流入する。可動体と被処理流体は、駆動源で駆動されて再び光触媒反応槽の上部から光触媒反応槽へと流入する。本実施の形態によれば、光触媒反応槽の下部に設けられた光触媒反応槽の内径より小さな外形の反応槽仕切板へと到達した可動体と被処理流体のうち可動体の多くは反応槽仕切板の上に載り、反応槽内の乱流によって反応槽内に拡散する。一方、可動体の一部と被処理流体は、光触媒反応槽の内壁と反応槽仕切板の外周との隙間を通過し、光触媒反応槽の下部より流出し分離槽流入管を通り分離槽へと流入する。このため、光触媒を担持させた可動体の多くが光触媒反応槽の内部に留まり、光源からの光と接触する割合が大きくなる。また、駆動源が停止した場合には可動体の多くが反応槽仕切板に載るため、光触媒反応槽の流出口に可動体が沈降堆積することがなく、駆動源を再駆動した場合に流出口が閉塞しないようにすることができる。
【００１８】
本発明の第３の実施の形態による被処理流体処理装置は、光触媒を担持させた可動体と被処理流体が光触媒反応槽の上部から光触媒反応槽へ流入し、光源体からの光によって可動体に担持された光触媒が、被処理流体に含まれる有機物を分解しつつ光触媒反応槽の下部へと移動する。光触媒反応槽の下部に到達した光触媒を担持させた可動体と被処理流体は、光触媒反応槽の下部より流出し分離槽流入管を通り分離槽へと流入する。分離槽へ流入した可動体と被処理流体はろ過され、被処理流体の一部が処理流体として被処理流体処理装置の外部へ排出される。被処理流体の残りと可動体は、分離槽の下部より流出し駆動源流入管へと流入する。駆動源流入管へ流入した可動体と被処理流体は、駆動源流入管の途中で被処理流体取り込み管を経由して、被処理流体貯留槽より分離槽で排出した処理流体とほぼ同量の被処理流体を被処理流体処理装置へ取り込み、駆動源へと流入する。可動体と被処理流体は、駆動源で駆動されて再び光触媒反応槽の上部から光触媒反応槽へと流入する。本実施の形態によれば、光触媒を担持させた可動体と被処理流体が光触媒反応槽の上部から光触媒反応槽へ流入し、光源体囲い板と光源体の隙間を通過しつつ、光源体からの光によって可動体に担持された光触媒が被処理流体に含まれる有機物を分解しつつ光触媒反応槽の下部へと移動する。このため、光触媒を担持させた可動体の粒子が小さく光を透過し難い場合や、着色排液を処理するため光が光触媒へ届きにくい場合などに、光源体囲い板と光源体の隙間で強力な光を照射することができ、効率のよく被処理流体を処理することができる。
【００１９】
本発明の第４の実施の形態による被処理流体処理装置は、第３の実施の形態における光源囲い板において、光源囲い板の内面を反射面としたものである。本実施の形態によれば、光源体からの光は光源囲い板で反射し、繰り返し光触媒と接触する。このため、光触媒と光の接触する割合が大きくなり効率よく被処理流体を処理することができる。
【００２０】
本発明の第５の実施の形態による被処理流体処理装置は、第１、第２、第３、第４の実施の形態における被処理流体処理装置において、光触媒反応槽内に光源体を配置した底面を設けたものである。本実施の形態によれば、光触媒反応槽から分離槽流出管へと流出する光触媒を担持させた可動体と被処理流体が必ず通過する光触媒反応槽の底面より光が照射される。このため、光触媒と光の接触する割合が大きくなり効率よく被処理流体を処理することができる。
【００２１】
本発明の第６の実施の形態による被処理流体処理装置は、第１、第２、第３、第４の実施の形態における被処理流体処理装置において、光触媒反応槽内に流出口へ向かう傾斜のついた底面を設け、この傾斜のついた底面に溝を備え、この溝部分に光源体を設けたものである。本実施の形態によれば、底面に傾斜と溝が付いているため光触媒を担持させた可動体は、滑らか溝に沿って光を照射されながら光触媒反応槽の流出口へと向かう。このため、光触媒を担持させた可動体が光触媒反応槽の流出口にて閉塞しにくく、光触媒と光の接触する割合が大きくなり効率よく被処理流体を処理することができる。
【００２２】
本発明の第７の実施の形態による被処理流体処理装置は、第１、第２、第３、第４、第５、第６の実施の形態における被処理流体処理装置において、分離槽内の下部に乱流沈殿槽を設け、乱流沈殿槽を通過した被処理流体を分離槽内の上部に設けたフィルターを通過させ、処理流体として分離槽より取り出すものである。本実施の形態によれば、乱流沈殿槽で可動体の大部分を取り除いた被処理流体をフィルターに通すことになる。このため、フィルターの寿命を伸ばすことができ、装置の運転管理費を低減することができる
【００２３】
【実施例】
以下、本発明による実施例の被処理流体処理装置について図面を参照して説明する。
【００２４】
図１は、本発明による一実施例の被処理流体処理装置を示す構成図である。光触媒を担持させた可動体３と被処理流体が、光触媒反応槽１の上部から流入し、光源体囲い板４と光源体２の隙間を通過しつつ、光源体２からの光によって可動体３に担持された光触媒が、被処理流体に含まれる有機物を分解しつつ光触媒反応槽の下部へと移動し反応槽仕切板５へ到達する。反応槽仕切板５へと到達した可動体３の多くは反応槽仕切板５の上に載り、光触媒反応槽１内の乱流によって光触媒反応槽１内に拡散する。このため、可動体３の多くが光触媒反応槽１の内部に留まり、光源体からの光と接触する割合が大きくなる。また、駆動源１７が停止した場合には、可動体３の多くが反応槽仕切板５に載るため、光触媒反応槽１の流出口に可動体３が沈降堆積することがなく、駆動源１７を再駆動した場合に流出口が閉塞しないようにすることができ、駆動源１７の損傷を防ぐこともできる。一方、可動体３の一部と被処理流体は、反応槽仕切板５と光触媒反応槽１の内壁との隙間を通過し、光触媒反応槽１の流出口に向かう傾斜のついた反応槽底面６に設置された光源体より光を照射され可動体３に担持された光触媒が、被処理流体に含まれる有機物を分解しつつ光触媒反応槽１の下部より流出し、分離槽流入管７を通り分離槽８へと流入する。分離槽８へ流入した可動体３と被処理流体は、分離槽の下部に設けられた乱流沈殿槽９でろ過され、次に分離槽８の上部に設けられたフィルター１０で最終的なろ過を行われ、被処理流体の一部が分離槽８の出口に設けた分離槽出口管２０から処理流体として流量調整弁１１を経由して被処理流体処理装置の外部へ排出される。被処理流体の残りと可動体３は分離槽８の下部より流出し駆動源流入管１２へと流入する。駆動源流入管１２へ流入した可動体３と被処理流体は、駆動源流入管１２の途中で被処理流体取り込み管１６を経由して被処理流体貯留槽１９より分離槽８で排出した処理流体とほぼ同量の被処理流体を被処理流体処理装置へ取り込み、駆動源流入管１４から駆動源１７へと流入する。可動体３と被処理流体は、駆動源１７で駆動されて光触媒反応槽流入管１８を経て再び光触媒反応槽１の上部から光触媒反応槽１へと流入する。ここで駆動源流出管１２と被処理流体取り込み管１６の途中に循環流量調節バルブ１３を設けてもよい。また、被処理流体取り込み管１６の途中に逆止弁１５を設けても良い。また、可動体３の量は被処理流体処理装置内を移動する被処理流体の２０％以下がよく、光触媒を担持させる可動体３は吸着性能をもったシリカゲルや活性アルミナを用いてもよい。また、光源体２は水中用紫外線殺菌ランプやブラックライトを用いてもよい。
【００２５】
図２は、図１における光源体囲い板４と光源体２の位置関係を断面で示したものである。光源体囲い板４Ａは光源体２の周囲を囲い、可動体３が光触媒反応槽１を仕切った光源体囲い板４Ａと一体となった上部受け板４Ｂに載り、次に可動体３が光源体２と光源体囲い板４Ａの間を光源体２の光を受けながら通過し下降していく。
【００２６】
図３は、図１における反応槽仕切板５のうち、反応槽仕切板５の外形が光触媒反応槽の内径より小さな場合を示している。反応槽仕切板５と光触媒反応槽の１には隙間があり、この隙間を可動体３の一部と被処理流体が通過する。
【００２７】
図４は、図１における反応槽仕切板５のうち、反応槽仕切板５に開口を設けた場合を示している。可動体３の一部は反応槽仕切板５の開口を通過する。
【００２８】
図５は、図１における光触媒反応槽の底面のうち、光触媒反応槽の流出口へ向かう傾斜と光源体を設置した底面の上面図を示したものである。底面６には光触媒反応槽１の流出口に向けて光源体３０を設置した溝３１が設置されている。

図６は、図１における光触媒反応槽１の底面のうち、光触媒反応槽１の流出口へ向かう傾斜と光源体３０を設置した底面６の上面図を示したものである。底面６には光触媒反応槽１の流出口に向けて光源体３０を設置した光触媒反応槽１の溝３１が設置されている。
