Description
また、活性炭は、過酸化水素の分解能力が高くないために、%オーダーの比較的高濃度の過酸化水素含有排水の処理には不適当であった。
このような過酸化水素分解触媒を用いる方法であれば、過酸化水素分解触媒を充填したカラムに被処理水を通水することにより、被処理水中の過酸化水素を効率的に分解処理することができ、特に、特許文献1で提案されるナノコロイド化した白金族金属の微粒子を担体に担持させた触媒であれば、反応速度が非常に速く、空間速度(SV)を大きくすることができ、通水液量が多いために触媒からの金属の流出の影響が小さくなり、また、触媒量が少なくて済み、処理コストを低減することができる。
このため、%オーダーの比較的高濃度の過酸化水素含有排水を処理する場合であっても、高濃度の過酸化水素を分解することにより生成した多量の酸素を円滑に系外に除去して、安定かつ効率的な連続処理が可能となる。
2H2O2→O2+2H2O
従って、被処理水を過酸化水素分解反応器2に導入した直後から酸素が発生し、過酸化水素分解反応器2内で酸素の気泡が生じることから、過酸化水素分解反応器2における被処理水の通水方向は、この気泡を排出し易くするために上向流通水とすることが好ましく、従って、図1に示す過酸化水素分解反応器2では、底部に被処理水の導入口を有し、上部に処理水の排出口を有する。
内径:線速度(LV)が0.05〜0.1m/secとなる内径
容器底部から流出水配管12接続部までの高さh:容器からの処理水排出部の圧力損
失の1〜3倍の水頭がとれる高さ
容器全体高さH:上記高さh×(2〜5)倍
(なお、円筒以外の筒状容器の場合、線速度に見合うように断面寸法が設計される。)
・排水配管14の管径(内径):筒状容器(円筒状容器)内径の0.5〜1.5倍
・排気配管13の管径(内径):排水配管14の0.2〜1.0倍
図1に示す過酸化水素水処理装置により、過酸化水素含有排水の処理を行った。
用いた過酸化水素水処理装置の各部の仕様は次の通りである。
に、過酸化水素分解触媒として、栗田工業(株)製「ナノセ
イバーS」(平均粒径2nmの白金ナノコロイド粒子を0.
1重量%の担持量で強塩基性ゲル型アニオン交換樹脂に担持
させたもの)を3L充填したもの。
25mmの排水配管と内径10mmの排気配管を接続したものであり、
過酸化水素分解反応器の流出水配管は、カラムの底部から100mmの
高さ位置(全高の1/3の高さ位置)に接続されている。
その結果、いずれの過酸化水素濃度の被処理水の場合も、処理水の過酸化水素濃度は測定下限値以下であり、また、処理に要した時間(過酸化水素分解反応器に導入されてから、気液分離器を経て排出されるまでの時間)は50秒程度であり、低濃度過酸化水素含有排水から高濃度過酸化水素含有排水まで、簡易な構成の過酸化水素水処理装置により短時間で効率的に過酸化水素の分解処理を行って、高水質の処理水を得ることができた。
実施例1で処理した各濃度の過酸化水素含有排水を、それぞれ30Lの貯槽に一旦貯留し、この貯槽に酵素(カタラーゼ)を添加して撹拌機で均一に撹拌することにより、過酸化水素の酵素による分解を行ったところ、一定の反応時間の確保のために、処理には6分程度(貯槽に入れてから酵素を添加して撹拌し、貯槽から排出するまでの時間)を要し、処理時間が長いと共に、装置も複雑なものとなった。

- 被処理水を過酸化水素分解触媒と接触させて、該被処理水中の過酸化水素を酸素と水とに分解して処理水を得る過酸化水素水処理装置において、
