摘要:
在落实国家“双碳”目标的大背景下，人工湿地CH4的排放及其调控越来越受到关注。系统性地探讨了人工湿地中CH4排放的机理、调控方法以及抗堵塞减排技术的研究进展，重点介绍了人工湿地中湿地类型、进水条件、温度、基质种类、植被类型等影响CH4排放的关键因素，综述和评估了水位调控、运行方式改变、新基质选用等针对CH4排放的调控方法，介绍了国内外人工湿地堵塞问题对CH4排放的影响以及相应的解决方案，特别是模块化抗堵塞人工湿地技术，为解决湿地堵塞问题提供了新的思路和方法。最后提出了未来研究的方向和挑战，尤其是在环境因素对CH4产生和排放的影响机制、新型抗堵塞人工湿地技术低CH4排放机理的进一步探索，以及传统人工湿地的低碳化改造等方面提出了具体的研究方向。这些工作将进一步加深对人工湿地CH4排放问题的理解，为湿地生态系统的保护和可持续发展提供重要的理论支持和技术指导。
Abstract:
In the context of implementing the “Carbon Peak and Carbon Neutralization” national strategic goals, CH4 emissions and regulation in constructed wetlands have received increasing attention. This paper systematically reviews the research progress on CH4 emission mechanisms, regulation strategies, reduction techniques, and clog mitigation technologies in constructed wetlands. It focuses on key factors influencing CH4 emissions, including wetland type, inflow condition, temperature, substrate type and vegetation type. Regulating measures for CH4 emissions, such as water-level management, adjustments to operational methods, and the selection of novel substrates, are also reviewed and evaluated. The impacts of the clogging issue on CH4 emissions in both domestic and overseas constructed wetlands, along with mitigation solutions, are discussed. Particular emphasis is placed on the modular moving bed constructed wetlands (MMB-CWs) technology, which offers new perspectives and approaches. Finally, this paper proposed future research directions and challenges, particularly focusing on the mechanisms by which environmental factors influence CH4 generation and emissions, and the low-emission mechanisms of MMB-CWs technology. Specific research directions of the low-carbon transformation of traditional constructed wetlands are also provided. These efforts will further deepen the understanding of CH4 emissions in constructed wetlands and provide important theoretical support and technical guidance for wetland ecosystems’ protection and sustainable development.
