- 摘要:
- 人工湿地用于废水处理是一项成本低且效益好的成熟技术。为了进一步优化该技术，降低建设成本，近年来发展了一系列人工湿地强化系统。在过去的10年，对微生物电化学技术与人工湿地相结合的探索为强化湿地处理系统提供了新的选择，形成了一系列耦合系统，并以较低的占地面积保持高性能运行。基于这种理念，阐释了微生物电化学技术的基本原理以及与人工湿地相结合的可能性和耦合系统效益。重点介绍了人工湿地-微生物燃料电池、人工湿地-微生物电解池、人工湿地-微生物电化学通气管等耦合体系的发展演变过程。讨论了耦合体系面临的挑战及发展前景，以期为微生物电化学技术与人工湿地耦合技术发展提供参考。
- Abstract:
- Constructed wetland (CW) is a mature technology with low cost and good efficiency for wastewater treatment. A series of intensified CW systems have been developed in recent years to further optimize this technology and reduce construction costs. In the past decade, there has been growing interest in exploring the possibility of merging microbial electrochemical technology (MET) with CW, offering a new option of an intensified wetland system that could maintain high performance with a lower footprint. Based on this concept, the general principles of MET, and the possibility and benefits of merging with CW were introduced. The development and evolution of several merging systems of constructed wetland-microbial fuel cell (CW-MFC), constructed wetland-microbial electrolytic cell (CW-MEC) and constructed wetland-microbial electrochemical snorkel (CW-MES) were highlighted. In addition, the challenges and development prospects of the merging systems were discussed. It is expected to provide a reference for the further development of MET and CW coupling technology.
