人工湿地/微生物燃料电池技术的发展现状

Current Status of Constructed Wetland/Microbial Fuel Cell

人工湿地技术(CW)和微生物燃料电池(MFC)处理技术都是通过微生物的作用去除污水中的污染物。微生物燃料电池的阳极区为厌氧环境、阴极区则为好氧环境,而氧化还原条件和氧化还原电位梯度在人工湿地填料层中可自然形成。因此,近几年兴起对这两种污水处理技术相结合的研究,由此开发了人工湿地/微生物燃料电池技术(CW/MFC)。虽然国内外对于CW/MFC的研究才刚起步,资料有限,但CW/MFC的雏形已经形成。在综述国内外已有的CW/MFC文献资料的基础上,提出这一环境友好型污水处理和潜能利用技术今后的研究方向及面临的挑战。

Constructed wetland( CW) and microbial fuel cell( MFC) are compatible technologies since both are reliant on the actions of bacteria to remove contaminants from wastewater. MFCs require the anode region to remain anaerobic with the cathode region exposed to oxygen while these redox conditions and gradients can develop naturally in CW. For this reason,research on combining the two technologies( termed as CW / MFC) has emerged in recent years. Based on the published work( although limited),the future challenges and research directions of the eco-friendly CW / MFC technololgy were put forward.
