Description
着色廃水を処理する方法としては、凝集・沈殿法(特許文献1〜特許文献3)や、色素を退色させる方法(特許文献4)、吸着剤に吸着させる方法(特許文献5)、分解触媒を担持した吸着剤を用いる方法(特許文献6)、さらには、酸化剤により着色物質を分解する方法なども提案されている(特許文献7)。
このような背景に鑑み、あらゆる着色廃液に万能で、BODやCOD対策にも役立つ着色廃液の処理材の開発も強く求められている。
水酸化カルシウムと各種のアルカリ金属のアルミン酸塩を表1に示すモル比で配合して着色廃水用処理材とした。この着色排水用処理材1.5gを着色廃水Aの1000ccに入れて攪拌し、5分後に廃液の色の変化を目視観察(色度観察)するとともに、着色物質の減少率やBODやCODの減少率を測定した。なお、比較のために、市販の着色廃水用処理材を用いた場合についても同様に行った。結果を表1に併記した。
水酸化カルシウム:市販の消石灰、BET比表面積m2/g。
アルカリ金属のアルミン酸塩(1):Na2O/Al2O3モル比が0.8のアルミン酸ナトリウム、無水物
アルカリ金属のアルミン酸塩(2):Na2O/Al2O3モル比が1.0のアルミン酸ナトリウム、無水物
アルカリ金属のアルミン酸塩(3):K2O/Al2O3モル比が1.0のアルミン酸カリウム、3水和物
アルカリ金属のアルミン酸塩(4):Na2O/Al2O3モル比が1.5のアルミン酸ナトリウム、5水和物
アルカリ金属のアルミン酸塩(5):Na2O/Al2O3モル比が2.0のアルミン酸ナトリウム、7水和物
処理材イ:市販の次亜塩素酸ナトリウム
処理材ロ:市販のハイドロタルサイト
着色廃水A:染色工業廃水、アゾ系染料を含む廃液
着色物質の減少量:処理材で処理する前の廃液の全炭素量と、処理材で処理後の廃液の全炭素量を有機全炭素分析装置(TOC)で定量した。処理前の廃液の全炭素濃度を100%とした時の、処理後の廃液の全炭素濃度の相対値から、有機分が99.9%以上低減された場合は○、90%以上低減されたが99.9%まで低減できなかった場合を△、90%まで低減されなかった場合を×とした。
BODおよびCOD:処理材で処理する前の廃液のBODまたはCODと、処理材で処理後の廃液のBODまたはCODをJIS K 0102に準じて測定した。処理前の廃液のBODまたはCODを100%とした時の、処理後の廃液のBODまたはCODとの相対値から、BODまたはCODが70%以上低減された場合は○、30%以上低減されたが70%まで低減できなかった場合を△、30%まで低減されなかった場合を×とした。
水酸化カルシウムと、アルカリ金属のアルミン酸塩(4)を表2に示すCaO/Al2O3モル比となるように配合して廃水処理材を調製したこと以外は実施例1と同様に行った。結果を表2に示す。
水酸化カルシウムとアルカリ金属のアルミン酸塩(4)とからなり、CaO/Al2O3モル比が4である廃水処理材を使用し、廃液1000ccに対する処理材の使用量を表3に示すように変化させたこと以外は、実施例1と同様に行った。結果を表3に示す。
水酸化カルシウムとアルカリ金属のアルミン酸塩(4)とからなり、CaO/Al2O3モル比が4である廃水処理材を使用し、着色廃液の種類を表4に示すように変化させたこと以外は、実施例1と同様に行った。結果を表4に示す。
着色廃水B:屎尿処理場の二次処理水
着色廃水C:糖蜜廃液
着色廃水D:下水汚泥の脱水プロセスで発生する熱処理分離液
Claims (2)
- 水酸化カルシウムとアルカリ金属のアルミン酸塩を含有してなり、アルカリ金属のアルミン酸塩のR2O/Al2O3モル比(RはNa、K)が0.8〜2、CaO/Al2O3のモル比が2〜4である、着色物質、及びBOD、CODを低減する着色廃水用処理材。
- 請求項1に記載の着色廃水用処理材を用いることを特徴とする着色廃水の処理方法。
