Description
図2において、電気脱イオン装置9は、電極(陽極21、陰極22)の間に複数のアニオン交換膜23及びカチオン交換膜24を交互に配列して脱塩室25と濃縮室26とを交互に形成し、両側に陽極室27と陰極室28を形成したものであり、脱塩室25にはイオン交換樹脂、イオン交換繊維もしくはグラフト交換体等からなるイオン交換体(アニオン交換体及びカチオン交換体)が混合もしくは複層状に充填されている。また、濃縮室26と、陽極室27及び陰極室28にも、同様にイオン交換体が充填されている。
上述したような構成を有する一次純水装置3の運転方法について説明する。まず、原水Wを前処理手段2により前処理を施した前処理水W1を一次純水装置3に供給し、逆浸透膜(RO)装置5で塩類除去のほかにイオン性、コロイド性のTOCを除去する。そして、脱気膜装置6で溶存気体を除去し、紫外線酸化装置7において残存する有機物を分解する。この紫外線酸化装置7で処理した被処理水W4を電気脱イオン装置9に通水して、UV酸化により分解した有機物に起因するイオン性の不純物を除去して、一次純水W2を製造する。
紫外線酸化装置7の処理水の模擬水として、純水に過酸化水素を添加した水(過酸化水素濃度:400μg/L)を調製した。この調製水を被処理水W4として図3及び表1に示す構造の電気脱イオン装置9に表2に示す通水条件で通水し、脱塩室25の入口の被処理水W4及び出口の脱塩水W5の過酸化水素濃度を溶存過酸化水素計(栗田工業(株)製 過酸化水素モニタ)により測定した結果を表3に示す。
実施例1において、図4及び表1に示す構造の電気脱イオン装置9に実施例1と同様の被処理水W4を表2に示す通水条件で通水し、脱塩室25の入口の被処理水W4及び出口の脱塩水W5の過酸化水素濃度を溶存過酸化水素計により測定した結果を表3にあわせて示す。また、電圧の上昇速度、装置寿命及び紫外線酸化装置の処理水を想定した場合の装置寿命を実施例1と同様にそれぞれ算出した。結果を表4にあわせて示す。
