Abstract

Copper-containing wastewater is produced in large quantities, threatening the environment yet having high recycling value. Proper disposal of copper in wastewater is crucial for environmental protection. The bioelectrochemical system (BES), including microbial fuel cells (MFC), microbial electrolysis cells (MEC), and microbial desalination cells (MDC), can remove pollutants and recover resources in wastewater via microorganisms and electric currents. Electrode materials, a key component, directly affect reactor efficiency and can be classified into carbon - based, metal, and modified electrodes, etc. Although research on BES treating copper - containing wastewater is increasing, there's no summary. This article fills the gap, focusing on BES reactor concepts, working principles, and development history; practical cases of treating copper - containing wastewater; and the impact of electrode materials and operating parameters on BES performance. Results show BES is a green, pollution - free, and efficient reactor, effective for treating copper - containing wastewater and promising for copper recovery. It also discusses reasons for current lab - stage research and difficulties in engineering applications, and proposes future development directions.

期刊介绍： The Journal of Environmental Chemical Engineering (JECE) serves as a platform for the dissemination of original and innovative research focusing on the advancement of environmentally-friendly, sustainable technologies. JECE emphasizes the transition towards a carbon-neutral circular economy and a self-sufficient bio-based economy. Topics covered include soil, water, wastewater, and air decontamination; pollution monitoring, prevention, and control; advanced analytics, sensors, impact and risk assessment methodologies in environmental chemical engineering; resource recovery (water, nutrients, materials, energy); industrial ecology; valorization of waste streams; waste management (including e-waste); climate-water-energy-food nexus; novel materials for environmental, chemical, and energy applications; sustainability and environmental safety; water digitalization, water data science, and machine learning; process integration and intensification; recent developments in green chemistry for synthesis, catalysis, and energy; and original research on contaminants of emerging concern, persistent chemicals, and priority substances, including microplastics, nanoplastics, nanomaterials, micropollutants, antimicrobial resistance genes, and emerging pathogens (viruses, bacteria, parasites) of environmental significance.
