Description

【０００１】
【発明の属する技術分野】
この発明は、廃水処理システムに設備された廃水濃度測定装置に利用される廃水希釈装置に関する。
【０００２】
【従来の技術】
廃水処理システムにおいて、処理すべき廃水の濃度管理は廃水処理システムを適正に機能させるための重要な管理項目の１つである。すなわち、処理すべき廃水の濃度に応じて処理の程度を制御する必要が有る。この廃水濃度管理の指標としては、「ＴＯＣ（全有機炭素）」、「ＴＯＤ（全酸素要求量）」、「ＢＯＤ（生物化学的酸素消費量）」、「ＣＯＤ（化学的酸素消費量）」等があり、これら指標を廃水中より直接測定する計測器も知られている。これらの計測器では、廃水を直接サンプリングし、計測器内に取込んで上記指標のための成分の含有量を計測するため、計測器の測定系やサンプリングした廃水の流路に廃水に含まれる汚濁物や浮遊物質（混濁物質）が付着し、蓄積し、スライム（微生物）が発生する。
【０００３】
従来は、計測系では、スライム発生を防止するため計測器内にストレーナやフィルタを設置して対処している。
【０００４】
【発明が解決しようとする課題】
しかしながら、このような従来の対処では、排水の汚れがひどいと、ストレーナやフィルタへの汚濁物や浮遊物質の蓄積が早く、この部分でスライムを発生する。このため、頻繁に計測器を分解し、測定系や流路、ストレーナ、フィルタを洗浄する必要があった。
【０００５】
そこで、本発明は、上記の問題点を解決できる廃水希釈装置を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記の目的を達成するため、本発明における概要は、廃水の一部をサンプリングし、サンプリング廃水を所定量の希釈水（清水等）を加えて希釈し、廃水濃度計測器に供給する廃水希釈装置とする。
【０００７】
また、廃水希釈装置そのものに、さらに洗浄手段を設けられる。
【０００９】
さらに具体的に説明すると、本発明では、廃水処理システムにおける廃水濃度測定装置に接続され、該装置に供給するサンプリング廃水を希釈する廃水希釈装置であって、廃水を受ける廃水受け容器と、当該容器に廃水を供給する廃水供給管路と、前記廃水受け容器への廃水供給量を認識する廃水認識手段と、前記廃水供給管路を開閉する廃水バルブ手段と、希釈用タンクと、該希釈用タンクに希釈用用水を供給する用水供給管路と、希釈用タンクへの希釈用用水供給量を認識する用水認識手段と、前記用水供給管路を開閉する用水バルブ手段と、前記廃水認識手段及び用水認識手段からの情報に基づき前記廃水バルブ手段及び用水バルブ手段の開閉を制御する制御手段と、前記希釈用タンクに廃水受け容器中の廃水を供給するために前記廃水受け容器を反転させる手段とを備える廃水希釈装置とする。これによって、廃水の汚れは自動的に希釈され、供給を受ける計測器のストレーナやフィルタへの汚濁物や浮遊物質の蓄積が極めて少なく、スライムの発生も極めてわずかとなる。このため、頻繁に計測器を分解し、測定系や流路、ストレーナ、フィルタを洗浄する作業回数を大幅に軽減することができる。さらに、廃水供給量と希釈用用水供給量を適切に管理して廃水に応じた希釈処理を可能とできる。
【００１０】
また、廃水処理システムにおける廃水濃度測定装置に接続され、該装置に供給するサンプリング廃水を希釈する廃水希釈装置であって、廃水を受ける廃水受け容器と、当該容器に廃水を供給する廃水供給管路と、前記廃水受け容器への廃水供給量を認識する廃水認識手段と、前記廃水受け容器より溢れた廃水を受ける廃水受け手段と、前記廃水供給管路を開閉する廃水バルブ手段と、希釈用タンクと、該希釈用タンクに希釈用用水を供給する用水供給管路と、希釈用タンクへの希釈用用水供給量を認識する用水認識手段と、前記用水供給管路を開閉する用水バルブ手段と、前記廃水認識手段及び用水認識手段からの情報に基づき前記廃水バルブ手段及び用水バルブ手段の開閉を制御する制御手段と、前記希釈用タンクに廃水受け容器中の廃水を供給するために前記廃水受け容器を反転させる手段とを備える廃水希釈装置とすれば、これによって、廃水の汚れは自動的に希釈され、供給を受ける計測器のストレーナやフィルタへの汚濁物や浮遊物質の蓄積が極めて少なく、スライムの発生も極めてはわずかとなる。このため、頻繁に計測器を分解し、測定系や流路、ストレーナ、フィルタを洗浄する作業回数を大幅に軽減することができる。さらに、廃水受け手段を設けたので、廃水を廃水受け容器に供給しているときに、万一容器から廃水が零れてしまった場合に、これを受け止めて、廃水処理装置に戻す等の処理を可能とできる。
【００１１】
また、廃水処理システムにおける廃水濃度測定装置に接続され、該装置に供給するサンプリング廃水を希釈する廃水希釈装置であって、廃水を受ける廃水受け容器と、当該容器に廃水を供給する廃水供給管路と、前記廃水受け容器への廃水供給量を認識する廃水認識手段と、前記廃水受け容器より溢れた廃水を受ける廃水受け手段と、前記廃水供給管路を開閉する廃水バルブ手段と、希釈用タンクと、該希釈用タンクに希釈用用水を供給する用水供給管路と、希釈用タンクへの希釈用用水供給量を認識する用水認識手段と、前記用水供給管路を開閉する用水バルブ手段と、前記廃水認識手段及び用水認識手段からの情報に基づき前記廃水バルブ手段及び用水バルブ手段の開閉を制御する制御手段と、前記廃水受け容器を廃水受け位置より前記希釈用タンクの位置に移動させる移動手段と、前記廃水受け容器が廃水受け位置にあることを検知する第一センサと、前記廃水受け容器が前記希釈用タンクの位置に有ることを検知する第二センサと、前記希釈用タンクに廃水受け容器中の廃水を供給するために前記廃水受け容器を反転させる手段と、前記廃水受け容器が反転したことを検知する第三センサと、前記第一、第二、第三センサからの情報に基づき前記移動手段及び反転手段の動作を制御する制御手段とを備える廃水希釈装置とすれば、これによって、廃水の汚れは自動的に希釈され、供給を受ける計測器のストレーナやフィルタへの汚濁物や浮遊物質の蓄積が極めて少なく、スライムの発生も極めてわずかとなる。このため、頻繁に計測器を分解し、測定系や流路、ストレーナ、フィルタを洗浄する作業回数を大幅に軽減することができる。さらに、廃水受け手段を設けたので、廃水を廃水受け容器に供給しているときに、万一容器から廃水が零れてしまった場合に、これを受け止めて、廃水処理装置に戻す等の処理を可能とできる。また、廃水受け容器を、廃水受け位置と廃水を希釈用タンクに供給する位置に移動させる手段及び位置確認用のセンサを設けたので、自動化による確実な動作を可能とできる。
【００１２】
また、前記希釈用用水を希釈用タンク洗浄バルブ手段を介して希釈用タンク洗浄用に供給する洗浄供給管路と、前記洗浄バルブ手段を制御する制御手段とを設けて、希釈廃水を濃度計測器に供給後、前記希釈用タンクを洗浄する廃水希釈装置とすれば、適切な希釈廃水を繰り返し供給できる。
【００１３】
また、前記希釈用用水を廃水供給管路洗浄バルブ手段を介して前記廃水供給管路に供給する洗浄供給管路と、前記廃水供給管路洗浄バルブ手段を制御する制御手段を設けて、定期的に前記廃水供給管路を洗浄する廃水希釈装置とすれば、廃水供給管路へのスライムの付着を定期的に除去できるため、長期にわたる継続使用が可能である。
【００１４】
また、前記希釈用タンクの洗浄後、廃水受け容器の洗浄を行う廃水希釈装置とすれば、廃水受け容器へのスライムの付着を廃水希釈工程を行うたびに除去でき、適切な希釈廃水を繰り返し供給できる。
【００１５】
【発明の実施の形態】
以下本発明の実施の形態を図を参照しつつ説明する。
【００１６】
図１乃至図１２は、本発明による一実施の形態についてのものである。
【００１７】
まず、図１乃至図４を参照して、本実施の形態の全体構成を説明する。
図１は、廃水希釈装置の配管系統図である。図２は、廃水受け容器駆動部の概念立面図、図３は、図１の廃水希釈装置の部分正面図、図４は、図１の廃水希釈装置の部分左側面図である。
【００１８】
ここでの廃水希釈装置１は、廃水希釈装置部２とこの廃水希釈装置部２を電気的に制御する電機制御部３からなっている。これらは、台座１ａ上に載置されている。廃水希釈装置部２は、廃水を受ける廃水受け容器部４と、当該廃水受け容器部４に所定量の廃水を供給する廃水供給部５と、希釈用タンク部６と、この希釈用タンク部６に廃水受け容器４ａ内の廃水を供給する廃水受け容器の駆動手段ここでは廃水受け容器駆動部１０と呼ぶ、と、希釈用タンク６ａに所定量の希釈用用水を供給する希釈用用水供給部７とを備えている。
【００１９】
廃水受け容器部４は、廃水受け容器４ａと、これからこぼれる廃水を受ける廃水受けタンク４ｂとから構成されている。
【００２０】
希釈用タンク部６は、希釈用タンク６ａと、このタンク内の廃水と希釈水とを混合する攪拌機Ｍ２と、希釈用タンク６ａの下方に繋がれた、分析装置ＴＯＣに希釈液を送り出すための希釈液管路ＳＰＤ１とを備えており、希釈液管路ＳＰＤ１には希釈液送り元弁Ｖ３と定量ポンプＭ１が設けられている。また、希釈用タンク６ａ底部には、残余の希釈液を排出するためのタンクブロー弁Ｖ４が繋がれている。
【００２１】
廃水供給部５は、廃水受け容器４ａへの廃水供給量を認識する廃水認識手段（図示せず。）と、廃水供給管路ＳＰＷ１、ＳＰＷ２と、前記廃水供給管路ＳＰＷ１、ＳＰＷ２を開閉する廃水バルブ手段としてのバルブＶ５，Ｖ６とから構成されている。希釈用用水供給部７は、希釈用タンク６ａに希釈用用水を供給する用水供給管路ＣＷ１，ＣＷ２と、希釈用タンク６ａへの希釈用用水供給量を認識する用水認識手段ここでは流量計Ｆ１と、前記用水供給管路CＷ２を開閉する用水バルブ手段としてのバルブＶ１とから構成されている。廃水認識手段及び用水認識手段Ｆ１からの情報に基づき廃水バルブ手段Ｖ５，Ｖ６及び用水バルブ手段Ｖ１の開閉は、電機制御部３により制御される。また、攪拌機Ｍ２等も、電機制御部３により制御される。
【００２２】
図２に示す廃水受け容器の駆動手段ここでは廃水受け容器駆動部１０は、廃水受け容器４ａを保持しかつ反転させるロ−タリーシリンダＳＬ２と、このロ−タリーシリンダＳＬ２を昇降可能に保持する昇降シリンダＳＬ３と、この昇降シリンダＳＬ３を左右に移動可能な移動シリンダＳＬ１とで構成される。各シリンダには、その位置検出のためセンサが設けられ、移動シリンダＳＬ１にはセンサＬＳ１とＬＳ２が、昇降シリンダＳＬ３にはセンサＬＳ５とＬＳ６が、ロ−タリーシリンダＳＬ２にはセンサＬＳ３とＬＳ４が設けられている。センサＬＳ１とＬＳ２とは、廃水受け容器４ａが廃水受け位置にあることを検知する第一センサとして、センサＬＳ１とＬＳ２及びセンサＬＳ５とＬＳ６とは、廃水受け容器４ａが希釈用タンク６ａの位置に有ることを検知する第二センサとして、また、センサＬＳ３とＬＳ４とは、希釈用タンク６ａに廃水受け容器４ａ中の廃水を供給するために廃水受け容器４ａを反転させる手段であるロ−タリーシリンダＳＬ２の反転したことを検知する第三センサとして働く、この第一、第二、第三センサからの情報に基づき廃水受け容器駆動部１０の移動及び反転の動作を電機制御部３内の制御手段が制御する。
【００２３】
また、この廃水希釈装置１では、希釈用用水を希釈用タンク洗浄用に供給する洗浄水供給管路ＣＷ４，ＣＷ５が設けられており、廃水受け手段としての廃水受けタンク４ｂの洗浄用には、洗浄供給管路ＣＷ６が設けられる。さらに、希釈用用水を廃水供給管路ＳＰＷ１，ＳＰＷ２の洗浄のため、洗浄供給管路ＣＷ３，ＣＷ７が設けられている。各洗浄供給管路ＣＷ５，ＣＷ６，ＣＷ７には、それぞれ洗浄バルブ手段であるバルブＶ２，Ｖ９，Ｖ７が設けられ、これらのバルブもまた電機制御部３内の制御手段により制御される。また、廃水受け容器４ａの洗浄のために、洗浄供給管路ＣＷ７には、洗浄バルブ手段であるバルブＶ８を介する枝分かれの洗浄供給管路ＣＷ８が設けられる。
【００２４】
上記の構成の具体的配置は、図３と図４に示している。廃水受け容器部４と希釈用タンク部６とは、ここでは、分離されて並置されており、廃水受け容器駆動部１０に保持された廃水受け容器４ａが電機制御部３に制御されて移動する。廃水受け容器部４と希釈用タンク部６の並び方向に、並行して移動シリンダＳＬ１が設置され、これに保持されて、昇降シリンダＳＬ３が設置される。ロ−タリーシリンダＳＬ２は昇降シリンダＳＬ３上に保持されて配置される。図４に示すように廃水受け容器４ａは、ロ−タリーシリンダＳＬ２と水平な回転リンクＬＫの先に保持されており、ロ−タリーシリンダＳＬ２により反転される。この反転状況は図１に模式的に示している。
【００２５】
次に、図１及び図５乃至図７に従って、この廃水希釈装置の動作フローの概略を説明する。図５は、廃水希釈装置における廃水希釈工程のフロー概略図で、図６は、希釈装置部の洗浄工程のフロー概略図である。また、図７は、廃水供給配管の洗浄工程のフロー概略図である。
【００２６】
上記実施の形態の動作は、その概要をかいつまんで示せば次のとおりである。廃水処理装置１によりサンプリングした廃水を所定量を廃水受け容器４ａで受け、このサンプル廃水を希釈用タンク部６にて希釈水を加えて希釈する。希釈用タンク６ａ内の希釈廃水は、分析装置（ＴＯＣ計測装置）ＴＯＣに送る。希釈用タンク６ａ内のサンプル廃水が所定以下となったとき、希釈サンプル廃水を廃棄し、続いて清水を希釈用タンク６ａ内に供給し、内部を洗浄する。更に、廃水受け容器４ａは廃水受け容器部４に戻り、洗浄水供給管路ＣＷ８，ＣＷ７，ＳＰＷ２を介して希釈水を廃水受け容器４ａに供給し、洗浄する。以上の廃水希釈工程、希釈用タンク６ａ、廃水受け容器４ａの洗浄の一連の工程は、所定回数反復される。なお、本実施例では、廃水供給管路ＣＷ７，ＳＰＷ２の洗浄は、上記所定回数反復毎に管路ＣＷ６を通して希釈水（ここでは清水）を供給し、洗浄する。
【００２７】
すなわち、廃水希釈装置の動作フローは、（１）廃水希釈工程（図５）、（２）希釈装置部の洗浄工程（図６）、（３）廃水供給配管の洗浄工程（図７）の３つに大きく分けられる。
【００２８】
（１）廃水希釈工程（図５）
図５において、廃水希釈装置の運転が開始される（１０１）。次に廃水受け容器（カップ）４ａの状態を判定する、廃水受け容器４ａが上向きかを確認、昇降シリンダＳＬ３の位置を判別し受け水位置かを確認する（１０２）。その後、廃水受け容器４ａへ廃水の所定量（この実施例では５０ｍｌ程度）を注入する（１０３）、一方希釈用タンク６ａに希釈用用水（希釈水、ここでは清水）を所定量（ここでは清水２４５０ｍｌ程度）給水する（１０４）。
【００２９】
次に、廃水受け容器駆動部１０を動作させカップ４ａを希釈用タンク６ａ上に移動する（１０５）。次に、カップ４ａ内の廃水を希釈用タンク６ａに注入する。これは、ロ−タリーシリンダＳＬ２の回転により行われカップ４ａの回転が確認される（１０６）。次に、希釈用タンク６ａ内に注入された希釈水（清水）と廃水の攪拌を攪拌機Ｍ２により行う（１０７）。十分に攪拌された希釈廃水を分析装置（ＴＯＣ計測装置）ＴＯＣに供給する。
【００３０】
（２）希釈装置部の洗浄工程（図６）
図６において、上記の図５の工程に続いて、希釈用タンク６ａ内の残余の希釈廃水を排出する（１１１）。次に、洗浄供給管路ＣＷ４，ＣＷ５を通して希釈水を供給し希釈用タンク６ａを洗浄する（１１２）。次に、廃水受け容器（カップ）４ａを当初の廃水受け位置に廃水受け容器駆動部１０によって復帰させる（１１３）。カップ４ａをロ−タリーシリンダＳＬ２によって上下に反転させながら洗浄する（１１４）。その後、カップ４ａを受水位置へ設置する（１１５）。
【００３１】
（３）廃水供給配管の洗浄工程（図７）
上記の図５の工程１０２乃至１０７に当る廃水（サンプリング）水希釈を行い（１２１）、希釈廃水の分析装置（ＴＯＣ計測装置）ＴＯＣへの供給（１０８、１２２）が行われ、図６の工程１１１乃至１１５で廃水希釈装置部２の洗浄を行う（１２３）。
【００３２】
本実施の形態では、上記の３工程１２１から１２３が何回か（ここでは、１０回）繰り返された後、すなわち、何回か（ここでは１０回）ごとに、次の工程が行われる。工程１２５では、廃水（サンプリング水）供給配管ＳＰＷ１の一部とＳＰＷ２の洗浄が洗浄供給管路ＣＷ３，ＣＷ７を通ってきた希釈水により行われる。その後、廃水（サンプリング水）希釈工程に再び移行する（１２６）。
【００３３】
次に、図１、図２と図８乃至１２に基づき、さらに具体的に、本実施の形態における
【００３４】
廃水希釈装置１の動作を説明する。図８乃至図１１は、廃水希釈装置における工程フロー部分図であり、一連の動作フロー図であるものを便宜上、各Ａ１，Ａ２と、Ａ３，Ａ４と、Ａ５，Ａ６とで切って図８乃至図１１としたものである。図１２は、廃水希釈装置における工程開始時の各部の原点位置（停止位置）を示すものである。
【００３５】
図８において、各囲みの矢印に沿って上から説明する。図９乃至１１についても同様に順次説明する。
【００３６】
運転開始に当り、運転釦がＯＮされると停止釦がＯＦＦとなる。（運転停止に当っては停止釦をＯＮすると運転釦がＯＦＦされる。）分析装置（ＴＯＣ計測装置）ＴＯＣから運転信号が確認のため送られてくる。センサＬＳ１により移動シリンダＳＬ１は廃水受け位置にあるか、センサＬＳ３によりロ−タリーシリンダＳＬ２及びカップ４ａは上向きか、センサＬＳ５により昇降シリンダＳＬ３は下端位置にあるかの確認がされ、運転状態ＯＮが続けられる。縁切弁Ｖ５が開かれタイマーＴ１０が働き６０秒後に閉止され、タイマーＴ１１で５秒間閉止状態となる。一方この間に、流量計Ｆ１はリセットされタイマーＴ２０で３秒後清水（希釈水）給水弁Ｖ１が開き流量計Ｆ１はスタートし、所定設定量（約６０秒）に達するとストップし清水給水弁Ｖ１も閉じる。
【００３７】
タイマーＴ１１と流量計Ｆ１の両者がＯＮすることにより昇降シリンダＳＬ３は上昇を開始し、センサＬＳ６ＯＮにて上昇が確認される。タイマーＴ３０によりその２秒後、移動シリンダＳＬ１が横移動を開始し、センサＬＳ２がＯＮにて横移動が確認される。タイマーＴ３１によりその２秒後、ロ−タリーシリンダＳＬ２は、カップ４ａを下向きにするように下向き回転を開始する。センサＬＳ４がＯＮにてカップ４ａの下向きが確認される。タイマーＴ３２による２秒後攪拌機Ｍ２が運転される。
【００３８】
ここで図９において、さらにタイマー４１で２秒後、循環ポンプ（定量ポンプ）Ｍ１が運転される。一方、タイマー４０で１０秒経過後の安定を待ち希釈液送り元弁Ｖ３が開かれる。希釈タンク６ａの希釈廃水のレベルが下限ＬＬレベルとなるとタイマーＴ４２がＯＮとなり３秒後循環ポンプＭ１が停止、攪拌機Ｍ２も停止する。その後タイマーＴ４３で２秒希釈液後送り元弁Ｖ３を閉じる。ここまでが、図５に対応する工程である。
【００３９】
次に希釈タンクブロー弁Ｖ４を開き、タイマーＴ５２が１０秒をカウントする間タンク残水を排出する。その後、希釈タンク洗浄弁Ｖ２を開き、タイマーＴ５１が１０秒をカウントする間希釈タンク６ａの洗浄が行われ、希釈タンク洗浄弁Ｖ２が閉じる。その後、タイマーＴ５２が１５秒をカウントする間タンク残水をブローし、希釈タンクブロー弁Ｖ４が閉じられる。タイマーＴ５３が２秒カウント後ロ−タリーシリンダＳＬ２がカップ４ａ上向きのための回転（上向回転）を始め、センサＬＳ３がＯＮとなってカップ４ａの上向き確認が行われ、さらにタイマーＴ６０が２秒カウント後（ここで図１０のＡ４点に続く）移動シリンダＳＬ１が横移動（戻り移動）を始める。センサＬＳ１がＯＮとなり横移動が確認されタイマーＴ６１が２秒カウント後、昇降シリンダＳＬ３が下降を始めセンサＬＳ５がＯＮとなって下降位置が確認される。タイマーＴ６２が２秒カウント後、カップ洗浄水元弁Ｖ８と廃水受けタンク洗浄弁（サンプリングタンク洗浄弁）Ｖ９とが開かれる、この間タイマーＴ６３が２秒カウント後ロ−タリーシリンダＳＬ２がカップ４ａ下向きのための下向回転を始める。センサＬＳ４がＯＮして下向回転によりカップ４ａが下向きになったことを確認し、タイマーＴ６４による２秒のカウント後ロ−タリーシリンダＳＬ２再び上向回転を始める。センサＬＳ３がＯＮによりカップ４ａの上向きになったことを確認し、タイマーＴ６５が２秒カウントして、再びロ−タリーシリンダＳＬ２は下向回転を始める、センサＬＳ４がＯＮとなりカップ４ａの下向きを確認、カップ洗浄水元弁Ｖ８と廃水受けタンク洗浄弁（サンプリングタンク洗浄弁）Ｖ９とがタイマーＴ６６で２秒カウント後閉じられる。さらにタイマーＴ６７が５秒をカウントし、（ここで図１１のＡ６点に続く）ロ−タリーシリンダＳＬ２が上向回転をはじめる。センサＬＳ３がＯＮとなり、カップ４ａの上向きが確認される。タイマーＴ６８が2秒カウントして廃水希釈・供給・希釈装置部の洗浄の１希釈洗浄工程が終了したため工程カウンタＣ６０に1カウントを加える。これまでが、図６の工程１１５までの工程であり、また、図７の工程１２４までの工程である。
【００４０】
ここでの工程カウンタＣ６０のカウント数が１０回未満のときは、図１０と図１１のＡ５点、図９と図１０のＡ３点、さらに、図８と図９のＡ１点を通ってＴＯＣよりの運転信号待ち状態に戻る。このときには、全てのシリンダＳＬ１，ＳＬ２，ＳＬ３，センサＬＳ１，ＬＳ３、ＬＳ５、弁Ｖ１乃至Ｖ９は、図１２に示す原点位置（停止位置）に戻っている。
【００４１】
工程カウンタＣ６０のカウント数が１０回となると、廃水（サンプリング水）供給配管の洗浄工程（図７の工程１２５でもある。）に移行する。
【００４２】
工程カウンタＣ６０のカウント数が１０回でカウンタＣ６０は、カウントアップし、サンプリングライン閉止弁Ｖ６が閉じる。タイマーＴ７０が2秒をカウントした後、サンプリングライン縁切弁Ｖ５とサンプリングライン洗浄水元弁Ｖ７とが開く、タイマーＴ７１が１０秒をカウント後、サンプリングライン洗浄水元弁Ｖ７は閉じる。タイマーＴ７２による２秒カウント後、サンプリングライン縁切弁Ｖ５とサンプリングライン洗浄水元弁Ｖ７とを閉じる。ここで、カウンタＣ６０は、リセットされる。タイマーＴ７３が2秒カウント後、図１０と図１１のＡ５点、図９と図１０のＡ３点、さらに、図８と図９のＡ１点を通ってＴＯＣよりの運転信号待ち状態に戻る（図７の工程１２５と１２６）。このときには、全てのシリンダＳＬ１，ＳＬ２，ＳＬ３，センサＬＳ１，ＬＳ３、ＬＳ５、弁Ｖ１乃至Ｖ９は、図１２に示す原点位置（停止位置）に戻っている。
【００４３】
なお、上記の実施の形態では、廃水受けタンク４ｂを希釈用タンク６ａと別に設けたが、希釈用タンクが、廃水受けタンク４ｂと希釈用タンク６ａの機能を兼用するものとして廃水受けタンクをなくすこともできる。また、廃水受け容器駆動部も、移動シリンダをなくし、ロ−タリーシリンダ又は昇降シリンダを左右回転可能にするなどして、簡素化、小型化を図ることもできる。
【００４４】
【発明の効果】
以上説明したように、本発明によれば、廃水処理システムにおける廃水濃度測定装置に接続され、該装置に供給するサンプリング廃水を希釈する廃水希釈装置において、廃水を受ける廃水受け容器と、当該容器に廃水を供給する廃水供給管路と、廃水受け容器への廃水供給量を認識する廃水認識手段と、廃水供給管路を開閉する廃水バルブ手段と、希釈用タンクと、該希釈用タンクに希釈用用水を供給する用水供給管路と、希釈用タンクへの希釈用用水供給量を認識する用水認識手段と、用水供給管路を開閉する用水バルブ手段と、廃水認識手段及び用水認識手段からの情報に基づき前記廃水バルブ手段及び用水バルブ手段の開閉を制御する制御手段と、前記希釈用タンクに廃水受け容器中の廃水を供給するために廃水受け容器を反転させる手段とを備える廃水希釈装置としたため、廃水の汚れは自動的に希釈され、供給を受ける計測器のストレーナやフィルタへの汚濁物や浮遊物質の蓄積が極めて少なく、スライムの発生も極めてはわずかである。このため、頻繁に計測器を分解し、測定系や流路、ストレーナ、フィルタを洗浄する作業回数を大幅に軽減することが出来る。

[0027]
That is, the operation flow of the waste water diluting device is as follows: (1) waste water diluting step (FIG. 5), (2) diluting unit cleaning step (FIG. 6), (3) waste water supply pipe cleaning step (FIG. 7). It can be roughly divided into two.
[0028]
(1) Wastewater dilution process (Figure 5)
In FIG. 5, the operation of the wastewater dilution apparatus is started (101). Next, the state of the waste water receiving container (cup) 4a is determined. It is confirmed whether the waste water receiving container 4a is upward, the position of the elevating cylinder SL3 is determined and the receiving water position is confirmed (102). Thereafter, a predetermined amount of waste water (about 50 ml in this embodiment) is poured into the waste water receiving container 4a (103), while a dilution amount (dilution water, here, fresh water) is supplied to the dilution tank 6a (here, fresh water). Water is supplied (104).
[0029]
Next, the waste water receiving container driving unit 10 is operated to move the cup 4a onto the dilution tank 6a (105). Next, the waste water in the cup 4a is poured into the dilution tank 6a. This is performed by the rotation of the rotary cylinder SL2, and the rotation of the cup 4a is confirmed (106). Next, the agitator M2 is used to stir the diluted water (fresh water) and waste water injected into the dilution tank 6a (107). The sufficiently stirred diluted wastewater is supplied to the analyzer (TOC measuring device) TOC.
[0030]
(2) Cleaning process of the diluting unit (FIG. 6)
In FIG. 6, following the process of FIG. 5, the remaining diluted waste water in the dilution tank 6a is discharged (111). Next, the dilution water is supplied through the cleaning supply lines CW4 and CW5 to clean the dilution tank 6a (112). Next, the waste water receiving container (cup) 4a is returned to the initial waste water receiving position by the waste water receiving container driving unit 10 (113). The cup 4a is washed while being turned upside down by the rotary cylinder SL2 (114). Thereafter, the cup 4a is installed at the water receiving position (115).
[0031]
(3) Waste water supply piping cleaning process (Fig. 7)
The waste water (sampling) water dilution corresponding to steps 102 to 107 in FIG. 5 is performed (121), and the diluted waste water is supplied to the analysis device (TOC measuring device) TOC (108, 122). In 111 to 115, the waste water dilution unit 2 is cleaned (123).
[0032]
In the present embodiment, after the above three steps 121 to 123 are repeated several times (here, 10 times), that is, every several times (here, 10 times), the next step is performed. In step 125, part of the waste water (sampling water) supply pipe SPW1 and SPW2 are washed with the diluted water that has passed through the washing supply pipes CW3 and CW7. Thereafter, the process proceeds to the waste water (sampling water) dilution step again (126).
[0033]
Next, based on FIG. 1, FIG. 2, and FIGS.
[0034]
The operation of the waste water dilution apparatus 1 will be described. FIG. 8 to FIG. 11 are process flow partial diagrams in the waste water diluting apparatus. For convenience, the series of operation flow diagrams are cut by A1, A2, A3, A4, A5, and A6. It is what was made into FIG. FIG. 12 shows the origin position (stop position) of each part at the start of the process in the wastewater dilution apparatus.
[0035]
In FIG. 8, it demonstrates from the top along the arrow of each enclosure. 9 to 11 will be sequentially described in the same manner.
[0036]
When the operation button is turned on at the start of operation, the stop button is turned off. (When the operation is stopped, the operation button is turned off when the stop button is turned on.) An operation signal is sent from the analyzer (TOC measuring device) TOC for confirmation. The sensor LS1 confirms whether the moving cylinder SL1 is in the waste water receiving position, the sensor LS3 confirms whether the rotary cylinder SL2 and the cup 4a are upward, and the sensor LS5 confirms whether the lift cylinder SL3 is in the lower end position. You can continue. The edge cut-off valve V5 is opened, the timer T10 is activated and closed after 60 seconds, and the timer T11 is closed for 5 seconds. Meanwhile, during this time, the flow meter F1 is reset, and after 3 seconds in the timer T20, the fresh water (diluted water) water supply valve V1 opens, and the flow meter F1 starts and stops when it reaches a predetermined set amount (about 60 seconds). Also close.
[0037]
When both the timer T11 and the flow meter F1 are turned on, the elevating cylinder SL3 starts to rise, and the rise is confirmed by the sensor LS6 ON. Two seconds later, the moving cylinder SL1 starts to move sideways by the timer T30, and the side movement is confirmed when the sensor LS2 is turned on. After 2 seconds by the timer T31, the rotary cylinder SL2 starts to rotate downward so that the cup 4a faces downward. The downward direction of the cup 4a is confirmed when the sensor LS4 is ON. After 2 seconds by the timer T32, the stirrer M2 is operated.
[0038]
Here, in FIG. 9, the circulating pump (metering pump) M <b> 1 is operated after 2 seconds by the timer 41. On the other hand, the diluent feed source valve V3 is opened after the timer 40 waits for stability after 10 seconds. When the level of the diluted waste water in the dilution tank 6a reaches the lower limit LL level, the timer T42 is turned ON, and after 3 seconds, the circulation pump M1 is stopped and the agitator M2 is also stopped. Thereafter, the feed valve V3 after 2 seconds of diluting liquid is closed by the timer T43. This is the process corresponding to FIG.
[0039]
Next, the dilution tank blow valve V4 is opened, and the tank remaining water is discharged while the timer T52 counts 10 seconds. Thereafter, the dilution tank cleaning valve V2 is opened, the dilution tank 6a is cleaned while the timer T51 counts 10 seconds, and the dilution tank cleaning valve V2 is closed. Thereafter, while the timer T52 counts 15 seconds, the remaining tank water is blown, and the dilution tank blow valve V4 is closed. After the timer T53 counts for 2 seconds, the rotary cylinder SL2 starts rotating (upward rotation) for the cup 4a upward, the sensor LS3 is turned on to check the upward of the cup 4a, and the timer T60 is further 2 seconds. After counting (here, following point A4 in FIG. 10), the moving cylinder SL1 starts to move sideways (return movement). After the sensor LS1 is turned on and the lateral movement is confirmed and the timer T61 counts for 2 seconds, the elevating cylinder SL3 starts to descend and the sensor LS5 is turned on to confirm the lowered position. After the timer T62 counts for 2 seconds, the cup cleaning water main valve V8 and the waste water receiving tank cleaning valve (sampling tank cleaning valve) V9 are opened. During this time, the timer T63 counts for 2 seconds, and the rotary cylinder SL2 faces the cup 4a downward. For the downward rotation to begin. The sensor LS4 is turned on and it is confirmed that the cup 4a is turned downward by the downward rotation, and after the counting by the timer T64 for 2 seconds, the rotary cylinder SL2 starts the upward rotation again. The sensor LS3 is turned on to confirm that the cup 4a is turned upward, the timer T65 counts for 2 seconds, and the rotary cylinder SL2 starts to rotate downward again. The sensor LS4 is turned on and the cup 4a is checked downward. The cup cleaning water source valve V8 and the waste water receiving tank cleaning valve (sampling tank cleaning valve) V9 are closed after 2 seconds are counted by the timer T66. Further, the timer T67 counts 5 seconds, and the rotary cylinder SL2 (following the point A6 in FIG. 11) starts to rotate upward. The sensor LS3 is turned on, and the upward direction of the cup 4a is confirmed. The timer T68 counts for 2 seconds and the one dilution cleaning process of the waste water dilution / supply / dilution apparatus section is completed, so 1 count is added to the process counter C60. The steps up to step 115 in FIG. 6 are the steps up to step 124 in FIG.
[0040]
Here, when the count of the process counter C60 is less than 10, the TOC passes through the point A5 in FIGS. 10 and 11, the point A3 in FIGS. 9 and 10, and the point A1 in FIGS. Return to the operation signal waiting state. At this time, all the cylinders SL1, SL2, SL3, sensors LS1, LS3, LS5, and valves V1 to V9 have returned to the origin position (stop position) shown in FIG.
[0041]
When the count number of the process counter C60 is 10, the process proceeds to the cleaning process of the waste water (sampling water) supply pipe (also the process 125 of FIG. 7).
[0042]
When the count number of the process counter C60 is 10, the counter C60 counts up and the sampling line closing valve V6 is closed. After the timer T70 has counted 2 seconds, the sampling line edge cut-off valve V5 and the sampling line washing water source valve V7 are opened. After the timer T71 has counted 10 seconds, the sampling line washing water source valve V7 is closed. After 2 seconds are counted by the timer T72, the sampling line edge cut-off valve V5 and the sampling line washing water source valve V7 are closed. Here, the counter C60 is reset. After the timer T73 counts for 2 seconds, it returns to the state waiting for the operation signal from the TOC through point A5 in FIGS. 10 and 11, point A3 in FIGS. 9 and 10, and point A1 in FIGS. 7 steps 125 and 126). At this time, all the cylinders SL1, SL2, SL3, sensors LS1, LS3, LS5, and valves V1 to V9 have returned to the origin position (stop position) shown in FIG.
[0043]
In the above embodiment, the waste water receiving tank 4b is provided separately from the dilution tank 6a. However, the dilution tank eliminates the waste water receiving tank as a function of the waste water receiving tank 4b and the dilution tank 6a. You can also. In addition, the waste water receiving container driving unit can be simplified and reduced in size by eliminating the moving cylinder and allowing the rotary cylinder or the lifting cylinder to rotate left and right.
