Currently, the treatment and utilization of acid mine drainage have become important issues of global environmental protection and resource conservation. Fe2+ bio-oxidation technology is widely used in the treatment of acid mine drainage. The basic principle is to use oxidation bacteria to oxidize Fe2+ to Fe3+, thereby promoting the precipitation and removal of other harmful substances in the wastewater. This paper mainly introduces the development history and technical characteristics of Fe2+ bio-oxidation technology, analyzes the advantages, disadvantages, challenges and opportunities of the technology. Based on this, a resource utilization scheme of acid mine drainage based on Fe2+ bio-oxidation technology is proposed in this paper, including Fe2+ bio-oxidation, Fe3+ precipitation and recovery, acid mine drainage neutralization and clarification, water recycling and reuse, etc. Finally, this paper puts forward the research direction and plan in the next step, aiming to further improve and optimize the application and promotion of the technology.精品文档---下载后可任意编辑Keywords: Fe2+ bio-oxidation; acid mine drainage; resource utilization; technical characteristics; challenges and opportunities.
