To investigate the effects of Fe\u2010C micro\u2010electrolysis on wastewater treatment, greenhouse gas emissions, and microbial communities, four intermittently aerated vertical\u2010flow constructed wetlands (CWs) were established: gravel\u2010based (GCW), biochar\u2010amended (BCW), zero\u2010valent iron (ZVI) amended (ZCW), and a combined biochar\u2010ZVI system (ICW). Results showed that all CW configurations effectively removed dyes (94%), COD (81%), and NO\n                    <jats:sub>3<\/jats:sub>\n                    <jats:sup>\u2212<\/jats:sup>\n                    \u2010N (94%).

Crucially, ICW also exhibited the lowest integrated GWP, achieving 62.75% reduction compared to GCW, with a further 31.2% reduction at higher dye concentrations. This significant greenhouse gas (GHG) mitigation originated from suppressed CH\n                    <jats:sub>4<\/jats:sub>\n                    emissions (indicated by a 26\u2010fold higher\n                    <jats:italic>pmoA<\/jats:italic>\n                    \/\n                    <jats:italic>mcrA<\/jats:italic>\n                    ratio, reflecting enhanced methanotrophy and suppressed methanogenesis) and reduced N\n                    <jats:sub>2<\/jats:sub>\n                    O emission, linked to an increased\n                    <jats:italic>nosZ<\/jats:italic>\n                    \/(\n                    <jats:italic>nirK<\/jats:italic>\n                    +\n                    <jats:italic>nirS<\/jats:italic>\n                    ) ratio (0.16 in ICW vs. 0.14 in GCW), signifying more complete denitrification (N\n                    <jats:sub>2<\/jats:sub>\n                    O to N\n                    <jats:sub>2<\/jats:sub>\n                    ). Mechanistic analysis revealed that ICW fostered the highest microbial richness (Sobs\u2009=\u20091818 OTUs) and diversity, significantly enriching key functional phyla (Proteobacteria, Bacteroidota, Chloroflexi, Desulfobacterota) and genera (\n                    <jats:italic>Flavobacterium<\/jats:italic>\n                    for dyes degradation;\n                    <jats:italic>Denitratisoma<\/jats:italic>\n                    , and\n                    <jats:italic>VadinHA17<\/jats:italic>\n                    for denitrification;\n                    <jats:italic>Desulfomonile<\/jats:italic>\n                    and\n                    <jats:italic>Geothrix<\/jats:italic>\n                    for electrogenesis). In this system, biochar promoted ammonia oxidation dominated by ammonia\u2010oxidizing archaea (\n                    <jats:italic>AOA<\/jats:italic>\n                    ) over ammonia\u2010oxidizing bacteria (\n                    <jats:italic>AOB<\/jats:italic>\n                    ), and served as an electron shuttle and carbon source, while ZVI supplied electrons for redox reactions. The synergistic Fe\u2010C micro\u2010electrolysis in ICW optimally integrated these functions, modulating the microbial community and enhancing key biochemical pathways. Thus, Fe\u2010C micro\u2010electrolysis offers dual advantages of efficient dyeing wastewater treatment and significant GHG mitigation, providing a novel low\u2010carbon solution for the remediation of complex industrial wastewater.\n                  <\/jats:p>","DOI":"10.1002\/wer.70408","type":"journal-article","created":{"date-parts":[[2026,5,12]],"date-time":"2026-05-12T00:44:27Z","timestamp":1778546667000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Fe\u2010C Micro\u2010Electrolysis Driven Dyeing Wastewater Purification in Constructed Wetlands"],"prefix":"10.1002","volume":"98","author":[{"given":"Shiwen","family":"Xu","sequence":"first","affiliation":[{"name":"Key Laboratory of Eco\u2010Environments in Three Gorges Reservoir Region (Ministry of Education), College of Resources and Environment Southwest University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingju","family":"Hao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Eco\u2010Environments in Three Gorges Reservoir Region (Ministry of Education), College of Resources and Environment Southwest University  Chongqing China"},{"name":"Interdisciplinary Research Center for Agriculture Green Development in Yangtze River Basin, College of Resources and Environment Southwest University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoya","family":"Chen","sequence":"additional","affiliation":[{"name":"Key Laboratory of Eco\u2010Environments in Three Gorges Reservoir Region (Ministry of Education), College of Resources and Environment Southwest University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziyao","family":"Wei","sequence":"additional","affiliation":[{"name":"Key Laboratory of Eco\u2010Environments in Three Gorges Reservoir Region (Ministry of Education), College of Resources and Environment Southwest University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenxiao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Eco\u2010Environments in Three Gorges Reservoir Region (Ministry of Education), College of Resources and Environment Southwest University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanxun","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Eco\u2010Environments in Three Gorges Reservoir Region (Ministry of Education), College of Resources and Environment Southwest University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuhang","family":"He","sequence":"additional","affiliation":[{"name":"Key Laboratory of Eco\u2010Environments in Three Gorges Reservoir Region (Ministry of Education), College of Resources and Environment Southwest University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiawei","family":"Ren","sequence":"additional","affiliation":[{"name":"Key Laboratory of Eco\u2010Environments in Three Gorges Reservoir Region (Ministry of Education), College of Resources and Environment Southwest University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6374-569X","authenticated-orcid":false,"given":"Changsheng","family":"Jiang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Eco\u2010Environments in Three Gorges Reservoir Region (Ministry of Education), College of Resources and Environment Southwest University  Chongqing China"},{"name":"Interdisciplinary Research Center for Agriculture Green Development in Yangtze River Basin, College of Resources and Environment Southwest University  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,5,11]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ecoenv.2021.113160"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jenvman.2023.117213"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclepro.2018.10.112"},{"key":"e_1_2_10_5_1","unstructured":"Duan C.
