Geochemical Modeling of Heavy Metal Removal from Acid Mine Drainage in an Ethanol-Supplemented Sulfate-Reducing Column Test Open
A passive treatment process using sulfate-reducing bacteria (SRB) is known to be effective in removing heavy metals from acid mine drainage (AMD), though there has been little discussion of the mechanism involved to date. In this work, a s…

Prediction of Acid Mine Drainage Treatment by Open Limestone-Alkaline Material Channel and Implications for the Large Scale Implementation of Passive Treatment Open
In decades, various studies on passive treatment methods of acid mine drainage (AMD) have been actively conducted in order to reduce the cost of AMD treatment. Open limestone channel is one of the most common methods and has already been i…

Removal of Mn(II) and Zn(II) Ions from Synthetic Mine Drainage Using a Laboratory-Scale Mn(II)-Oxidizing Bioreactor Open
鉱山で排出されるマンガン含有坑廃水の生物処理技術の開発を目的として、マンガン酸化細菌を用いたバイオリアクター試験を検討した。マンガン酸化物及びマンガン酸化能を有する細菌群集が付着した石灰石を充填した小型バイオリアクターを構築し、Mn2+イオン単独またはMn2+及びZn2+イオンを含む模擬坑廃水を通水して、これらの金属イオンの負荷がマンガン除去に及ぼす影響を調査した。水理学的滞留時間は24時間に、初期Mn2+濃度は10 mg/Lに設定した。試験の結果、マンガン除去速度はリアク…

Iron Redox Transformation by the Thermo-Acidophilic Archaea from the Genus <i>Sulfolobus</i> Open
Iron redox transformations by five representative Sulfolobus strains (S. metallicus Kra23; S. tokodaii 7; S. acidocaldarius 98-3; S. solfataricus P1; S. shibatae B12) were studied to clarify the general trend of Fe metabolism across differ…
