Abstract

Self-sustaining and eco-friendly technologies for wastewater treatment are crucial for promoting sustainable development goals and advancing circular economy approach. Therefore, here we review the popular nature-based wastewater treatment systems i.e., constructed wetlands (CWs). The review focuses on recent advancement in the field of CWs, with main focus on bio-electrochemical systems (BES) integration with constructed wetlands (BES-CWs). The integration of CWs with BES provides a self-sustaining and an eco-friendly option for sustainable wastewater treatment and energy production. However, to date pilot scale applicability of these systems has been limited due to low energy out-put. Hence, in this review we discuss BES-CWs systems, evolution and advancement, highlighting the research advancements over the years. The discussion includes advancement in design configuration, filter media used, electrode material and microbial communities which influence the performance of the BES-CWs system and subsequently highlight limiting factors for pilot scale applicability. The review findings reveal that BES-CWs systems have strong potential for wastewater treatment, but special attention to the design, substrate and electrode material is required to enhance the energy out-put. The, review analysis will assist in future research work and offer new avenues for optimization of BES-CWs for wastewater treatment and energy production.

清洁水和绿色能源生物电化学人工湿地研究进展

废水处理的自我维持和生态友好技术对于促进可持续发展目标和推进循环经济方法至关重要。因此，在这里我们回顾了流行的基于自然的废水处理系统，即人工湿地（CWs）。本文综述了人工湿地领域的研究进展，重点介绍了生物电化学系统（BES）与人工湿地的集成。化粪池与BES的整合为可持续的废水处理和能源生产提供了一个自我维持和环保的选择。然而，到目前为止，由于能量输出低，这些系统的中试规模适用性受到限制。因此，在本文中，我们讨论了BES-CWs系统，演变和进展，重点介绍了近年来的研究进展。讨论了影响BES-CWs系统性能的设计配置、使用的过滤介质、电极材料和微生物群落的进展，并随后强调了中试规模适用性的限制因素。综述结果表明，BES-CWs系统具有很强的废水处理潜力，但需要特别注意设计、衬底和电极材料，以提高能量输出。综述分析将有助于今后的研究工作，并为优化BES-CWs用于废水处理和能源生产提供新的途径。
