As a result, stable operation of the block 2a can be realized.

Abstract
Description
また、従来の水処理装置では、運転トラブルの際に濾過膜モジュール及び逆浸透膜モジュール全ての濾過処理を停止せざるを得ず、安定的な処理水の供給ができないという問題が生じていた。
加えて、従来の水処理装置を洗浄する際は、装置内の各モジュール全体を洗浄する必要があり、安定的な処理水の供給ができないという問題が生じていた。
加えて、装置内の各モジュール全体を洗浄する必要がなくなり、一部のユニット構造体を洗浄しながら他のユニット構造体で濾過運転を継続できるため安定的な処理水の供給ができる。また、処理要求に応じた設置面積の増減を容易にできる。
このように、水処理部を有するユニット構造体の増減を容易に行うことができるので、所望の水処理能力に応じて施工現場での設置作業及び撤去作業を容易に行うことが可能となる。
そこで透過処理能力を所定値以上であるユニット構造体を用いることで、当該課題を解決することができた。前記ユニット構造体それぞれの透過水処理能力が20m3/h以上であることが好ましく、30m3/h以上であることがさらに好ましい。搬送可能なベース上での作業性及びメンテナンスの容易性から75m3/h以下が好ましく、60m3/h以下がより好ましい。このようにすれば、従来の単床式イオン交換樹脂塔と比べて処理水の処理能力を大幅にアップすることが可能となり、処理水の水量が同じである場合、従来より装置をコンパクトすることができる。また、従来水処理装置と比較して設置に必要な面積を小さくすることができる。水処理装置がコンパクトであるので、小規模水処理プラントに好適であるばかりか、透過処理能力が所定値以上であることによって、設置台数を多くしなくとも大規模水処理プラントでも適用できる。また、従来から搬送可能なベースの上に水処理装置を設置することは知られている。しかし、その多くは小規模又は仮設等臨時で使用されるものであり、大規模・恒久的な使用の場合、通常建屋内に水処理装置の一部又は全部を設置するのが一般的であった。しかしながら、本願発明によれば、搬送可能でありながらベース面積あたりの水処理能力が高いため、搬送体の台数も少なく、かつ建屋を設置することなく大規模で恒久的な搬送可能なベースを備えた水処理装置を提供できる。
さらに、水処理部は、濾過膜モジュールと逆浸透膜モジュールとを有し、濾過膜モジュールで処理された処理水は、高圧ポンプを介して直接に逆浸透膜モジュールに供給されると好適である。この構成では、濾過膜モジュールと逆浸透膜モジュールとを有するので、例えば砂濾過等に比べて処理水の水質の向上と省スペース化とを図り易くなる。また、逆浸透膜モジュールの目詰まりを濾過膜モジュールによって抑止できるので、安定した運転を図ることが可能となる。さらに、濾過膜モジュールと逆浸透膜モジュールとの間に、一時的に処理水を蓄えておく中間タンクなどは介在しないので、省スペース化に有効である。
また、ブロックなどのユニット構造体を複数備えた水処理装置においては、例えば移送ポンプ、逆洗設備、計装設備等もユニット構造体の数だけ必要なため、水処理量が増大するとそれに応じて設置面積も増大する場合がある。
そこで透過処理能力を所定値以上であるブロック2a~2cを用いることで、当該課題を解決することができた。ブロック2a~2cそれぞれの透過水処理能力が20m3/h以上であることが好ましく、30m3/h以上であることがさらに好ましい。搬送可能なベース9a~9c上での作業性及びメンテナンスの容易性から75m3/h以下が好ましく、60m3/h以下がより好ましい。このようにすれば、従来の単床式イオン交換樹脂塔と比べて処理水の処理能力を大幅にアップすることが可能となり、処理水の水量が同じである場合、従来より装置をコンパクトすることができる。また、従来水処理装置と比較して設置に必要な面積を小さくすることができる。水処理装置1がコンパクトであるので、小規模水処理プラントに好適であるばかりか、透過処理能力が所定値以上であることによって、設置台数を多くしなくとも大規模水処理プラントでも適用できる。また、従来から搬送可能なベースの上に水処理装置を設置することは知られている。しかし、その多くは小規模又は仮設等臨時で使用されるものであり、大規模・恒久的な使用の場合、通常建屋内に水処理装置の一部又は全部を設置するのが一般的であった。しかしながら、本実施形態に係る水処理装置1によれば、搬送可能でありながらベース9a~9cの面積あたりの水処理能力が高いため、搬送体の台数も少なく、かつ建屋を設置することなく大規模で恒久的な搬送可能なベースを備えた水処理装置を提供できる。
