Application of Zero-Valent Iron Coupled Anaerobic Biological Method in Wastewater Treatment

The coupling of zero-valent iron with microorganisms is a promising technology that has received widespread attention for contaminants removal from wastewater. The coupling technology effectively integrates the high efficiency of zero-valent iron technology and the economics of anaerobic biotechnology, and effectively reduces the bioinhibition and toxicity of refractory organic substances under the synergistic effect of multiple microelectric field and anaerobic microorganisms. This article reviews the potential mechanism of this technology for industrial wastewater treatment, the main operating parameters and influencing conditions in practical applications, and the research progress in the treatment of biorefractory pollutants including chlorinated compounds, heavy metals and dyes. This paper summarizes the research status of the above pollutants by the coupling of ZVI and microoganisms, and prospects for the feasible strategies of this technology in practical engineering applications.
