| 中文摘要: |
| 随着畜禽养殖业向规模化、集约化方向发展，畜禽养殖过程中产生的大量废水成为畜禽养殖场周围环境污染的重要因素。微生物燃料电池（Microbial Fuel Cell，MFC）作为一种电化学微生物技术，能够在去除废水中有机物的同时产生电能，在处理高浓度畜禽养殖废水方面具有广阔的发展和应用前景。本文介绍了MFC的分类，并从污染物（化学需氧量、氨氮、总磷和抗生素）去除和产电性能两个方面分析MFC在畜禽养殖废水处理领域的研究现状，并拓展性地阐述了新型耦合MFC技术处理畜禽养殖废水的应用前景，最后指出MFC处理畜禽养殖废水存在的问题，并提出未来可行的发展方向，包括放大装置尺寸、开发新型耦合MFC技术、研究参数的交互作用、深入发掘污染物去除机理和电子传递机制。 |
| 英文摘要: |
| Rapid scale-up and intensification of the livestock and poultry farming industry generates massive amount of wastewater that greatly contributes to the environmental pollution in the vicinity. The microbial fuel cell（MFC）is an electrochemical technology that enables removal of organic pollutants in the wastewater and power generation concomitantly with the aid of microorganisms. This technology has a great potential in treating high-concentration wastewater released from the livestock and poultry farming. The present study described the categories of MFCs and current research status of its application in wastewater treatment from two aspects： 1）removal of organic pollutants（e.g., chemical oxygen demand, ammonia nitrogen, total phosphorus, and antibiotics）and 2）electricity production performance. The potential of using multiple MFC technologies together in wastewater treatment was also elaborated. This study revealed the existing problems associated with current MFC technologies and provided directions for future research, including equipment scale-up, development of novel coupling MFC technologies, interpretation of interactions among controllable parameters, and in-depth exploitation of mechanisms underlying pollutant removal and electron transfer. |
