The constructed wetland coupled with a microbial fuel cell (CW-MFC) is a wastewater treatment process that combines contaminant removal with electricity production, making it an environmentally friendly option. This hybrid system primarily relies on anaerobic bioprocesses for wastewater treatment, although other processes such as aerobic bioprocesses, plant uptake, and chemical oxidation also contribute to the removal of organic matter and nutrients. CW-MFCs have been successfully used to treat various types of wastewater, including urban, pharmaceutical, paper and pulp industry, metal-contaminated, and swine wastewater. In CW-MFC, macrophytes such as rice plants, Spartina angalica, Canna indica, and Phragmites australis are used. The treatment process can achieve a chemical oxygen demand removal rate of between 80 and 100%. Initially, research focused on enhancing power generation from CW-MFC, but recent studies have shifted towards resource recovery from wastewater. This review paper provides an overview of the development of constructed wetland microbial fuel cell technology, from its early stages to its current applications. The paper also highlights research gaps and potential directions for future research.
人工湿地与微生物燃料电池（CW-MFC）相结合是一种废水处理工艺，它将污染物去除与电能生产相结合，是一种环保的选择。该混合系统主要依靠厌氧生物过程进行废水处理，尽管其他过程，如好氧生物过程、植物吸收和化学氧化，也有助于去除有机物和营养物质。CW-MFC 已成功用于处理各种类型的废水，包括城市、制药、造纸和纸浆工业、金属污染和养猪废水。在 CW-MFC 中，使用了水稻、大米草、美人蕉和芦苇等大型植物。处理过程可实现 80%至 100%的化学需氧量去除率。最初，研究重点是提高 CW-MFC 的发电能力，但最近的研究已转向从废水中回收资源。本文综述了人工湿地微生物燃料电池技术的发展，从早期到目前的应用。本文还强调了研究差距和未来研究的潜在方向。
