Abstract
Description
[1] 酸性温泉水又は酸性鉱山排水に、中和可能な砕石を投入することにより中和させる工程(中和工程)と、前記中和工程に伴って、前記酸性温泉水又は酸性鉱山排水中に含まれる少なくとも一種の元素を前記砕石に吸着させる工程、及び/又は、前記砕石中に含まれる少なくとも一種の元素を前記酸性温泉水又は酸性鉱山排水に溶出させて回収する工程を含むことを特徴とする、酸性温泉水又は酸性鉱山排水の処理方法。
[2] 前記砕石は、超苦鉄質岩、苦鉄質岩及び凝灰岩からなる群から選ばれる少なくとも一種の岩石を含むことを特徴とする、前項1に記載の酸性温泉水又は酸性鉱山排水の処理方法。
[3] 前記吸着させる工程において、前記元素はヒ素、鉛、セシウムからなる群から選ばれた少なくとも一種の元素であることを特徴とする、前項1又は2に記載の酸性温泉水又は酸性鉱山排水の処理方法。
[4] 前記中和工程に伴って前記砕石中に含まれる少なくとも一種の元素が、イットリウム、ランタン、セリウム、プラセオジム、ネオジム、サマリウム、ユウロピウム、ガドリニウム、テルビウム、ジスプロシウム、ホルミウム、エルビウム、ツリウム、ルテチウム、イッテルビウムからなる群から選ばれることを特徴とする、前項1乃至3の何れか1項記載の酸性温泉水又は酸性鉱山排水の処理方法。
[5]前記回収する工程が、前記元素を含む上澄み液を、少なくともpH3以上に酸性度を低下させて前記元素を含む殿物を回収することを特徴とする、前項1乃至4の何れか1項に記載の酸性温泉水又は酸性鉱山排水の処理方法。
[6]前項5に記載の酸性温泉水又は酸性鉱山排水の処理方法によって回収された殿物。
本発明で好ましく用いられる砕石とは、例えば超苦鉄質岩、苦鉄質岩及び凝灰岩からなる群から選ばれる少なくとも一種の岩石であって、前記超苦鉄質岩は殆どがカンラン石、輝石、角閃石などの苦鉄質鉱物(マフィック鉱物)からなり、長石や石英などの珪長質鉱物(フェルシック鉱物)を殆ど含まない岩石であり、前記苦鉄質岩には枕状溶岩、粗粒玄武岩、玄武岩質火山砕屑岩などが含まれ、また前記凝灰岩には流紋岩質凝灰岩等が含まれる。玄武岩は、苦鉄質火山岩の一種であり、SiO2が45〜52質量%で斑状組織を有するものとして知られ、含まれる鉄分の酸化によって赤 - 紫色の状態もある。SiO2以外の成分として、Al2O3が約15質量%、Fe2O3が数質量%、FeOが約10質量%、MgOが6〜8質量%、CaOが約10質量%を含む岩石である。
また図2において、粗粒玄武岩を投入した後の上澄み液に含まれていたセシウムは、元の温泉水よりも増加しており、前述砕石からセシウムが溶出した。一方、玄武岩質火山砕屑岩の投入により、上澄み液中に含まれるセシウムの濃度は減少していた。前述の砕石混合物を投入した結果、明らかにセシウムの吸着が確認された。
