Abstract

The traditional constructed wetlands (CWs) face challenges such as significant seasonal fluctuations in decontamination performance and susceptibility to clogging, with the bottlenecks in advanced wastewater treatment becoming increasingly prominent. The iron‒carbon microelectrolysis coupled with constructed wetlands (ICME‒CWs) represents a promising new type of CWs, capable of removing typical and emerging pollutants in water through various mechanisms including adsorption, precipitation, oxidation‒reduction, microelectrolysis, and plant‒microbial synergy. Therefore, this review summarizes the sources, preparation, and basic properties of the ICME substrate commonly used in ICME‒CWs in recent years. It systematically outlines the decontamination mechanisms of ICME‒CWs and their removal performance for pollutants. Additionally, the potential ecological effects of ICME on wetland organisms (microorganisms and plants) are discussed. Finally, the prospects and challenges of ICME‒CWs in applications such as greenhouse gas reduction, groundwater remediation, and the removal of emerging pollutants are proposed. This review aims to advance the development of ICME‒CWs technology for efficient wastewater treatment and provide prospects and guidance for the sustainable and environmentally friendly development of CWs.

铁碳微电解构建湿地综述：效率、机理与前景

传统的人工湿地（CWs）面临着净化性能季节性波动大、易堵塞等挑战，先进的污水处理瓶颈日益突出。铁碳微电解耦合建造湿地（ICME-CWs）是一种前景广阔的新型建造湿地，能够通过吸附、沉淀、氧化还原、微电解和植物微生物协同作用等多种机制去除水中的典型和新兴污染物。因此，本综述总结了近年来在 ICME-CW 中常用的 ICME 基质的来源、制备方法和基本特性。它系统地概述了 ICME-CWs 的去污机制及其对污染物的去除性能。此外，还讨论了 ICME 对湿地生物（微生物和植物）的潜在生态影响。最后，提出了 ICME-CWs 在温室气体减排、地下水修复和去除新兴污染物等方面的应用前景和挑战。本综述旨在推动 ICME-CWs 技术在高效废水处理方面的发展，并为 CWs 的可持续和环境友好型发展提供展望和指导。

期刊介绍： Water Research, along with its open access companion journal Water Research X, serves as a platform for publishing original research papers covering various aspects of the science and technology related to the anthropogenic water cycle, water quality, and its management worldwide. The audience targeted by the journal comprises biologists, chemical engineers, chemists, civil engineers, environmental engineers, limnologists, and microbiologists. The scope of the journal include: •Treatment processes for water and wastewaters (municipal, agricultural, industrial, and on-site treatment), including resource recovery and residuals management; •Urban hydrology including sewer systems, stormwater management, and green infrastructure; •Drinking water treatment and distribution; •Potable and non-potable water reuse; •Sanitation, public health, and risk assessment; •Anaerobic digestion, solid and hazardous waste management, including source characterization and the effects and control of leachates and gaseous emissions; •Contaminants (chemical, microbial, anthropogenic particles such as nanoparticles or microplastics) and related water quality sensing, monitoring, fate, and assessment; •Anthropogenic impacts on inland, tidal, coastal and urban waters, focusing on surface and ground waters, and point and non-point sources of pollution; •Environmental restoration, linked to surface water, groundwater and groundwater remediation; •Analysis of the interfaces between sediments and water, and between water and atmosphere, focusing specifically on anthropogenic impacts; •Mathematical modelling, systems analysis, machine learning, and beneficial use of big data related to the anthropogenic water cycle; •Socio-economic, policy, and regulations studies.
