Description
RO膜フラックスを低下させる原因である汚泥から溶出したTOC成分は、アルカリ性領域では膜面に吸着し難く、RO給水となるMBR処理水のpHを9.5以上にすることによりRO膜面へのこれらの成分の付着を抑制することが可能となる。
また、微生物はアルカリ性域では生息することができない。そのため、MBR処理水のpHを9.5以上に調整することにより、RO膜分離装置内において、栄養源はあるが微生物が生息できない環境を作り出すことが可能となり、RO膜分離装置でのスライムの生成を抑制することができる。
本発明で処理対象とする有機物含有水、例えば、電子産業用部品の製造工場等から排出される有機物含有水中には稀にスケールの元となるカルシウムイオンなどが混入する場合がある。RO給水のpHを9.5以上とする高pHのRO運転条件では、極微量のカルシウムイオンの混入でも炭酸カルシウムなどのスケールが生成し、RO膜が直ちに閉塞してしまう。そこで、本発明では、このようなスケールによる膜面閉塞を抑制する目的から、RO給水となるMBR処理水に、スケール防止剤を添加してスケールの生成を防止する。
膜形状としては、平膜、管状膜、中空糸膜等各種のものを用いることができる。また、膜材質は、ポリフッ化ビニリデン(PVDF)、ポリエチレン(PE)、ポリプロピレン(PP)等各種のものを用いることでできる。
上記の酸化剤の洗浄剤、酸性の洗浄剤は1種を単独で用いてもよく、2種以上を混合して用いてもよい。これら洗浄剤成分は、通常、シュウ酸やクエン酸であれば1〜5wt%程度の水溶液、また、次亜塩素酸ナトリウムであれば塩素換算濃度として500〜5000mg−Cl/L程度の水溶液として膜洗浄に用いられる。
図1の有機物含有水の処理装置を用い、電子産業排水(TOC:80〜100mg/L)を原水として、負荷0.5〜1.0kg−BOD/m3/dで好気性MBR(汚泥濃度:4,000〜8,000mg/L)処理を行った。MBR生物処理槽2の分離膜、RO膜分離装置4のRO膜としては以下のものを用いた。通常運転時のMBR処理水(膜透過水)のTOCは3〜5mg/Lであった。
分離膜:PVDF製浸漬型中空糸UF膜(三菱レイヨン株式会社製,膜面積12m2)
RO膜:芳香族ポリアミド製スパイラル型RO膜(日東電工株式会社製)
膜洗浄液注入直後のMBR処理水(膜透過水)は、残留塩素が検出されるため、膜洗浄後1時間はRO膜分離装置4に送給せずに原水タンク1に返送した。
その後、MBR処理水(膜透過水:TOC5〜10mg/L,pH5.5)に水酸化ナトリウムを添加してpH10.5に調整すると共に、キレート系スケール防止剤(栗田工業株式会社製「ウェルクリンA801」)を30ppm添加した後RO膜分離装置4に通水した(水回収率85%)。
このときのRO膜分離装置4のRO膜フラックスと水回収率の経時変化を調べ、結果を図2に示した。
実施例1においてMBR処理水(pH5.5)に水酸化ナトリウムとスケール防止剤を添加せず、イソチアゾリン系スライムコントロール剤(栗田工業株式会社製「クリバータ EC503」)を3ppm添加してRO膜分離装置に通水したこと以外は同様に処理を行い、RO膜分離装置のRO膜フラックスと水回収率の経時変化を調べ、結果を図2に示した。
