Method for emergency remediating halogenated organic contaminated site with metal-rich biochar

Abstract

It discloses a method for emergency remediating halogenated organic polluted site(s), by constructing a microelectric field driven bioelectrochemical system of engineering bacteria and auxiliary agent(s). The micro-electric field has cast iron electrode or copper zinc biochar electrode as the anode and plastic electrode as the cathode. The copper zinc biochar is produced by enriching copper, zinc in situ in watercanna, and then pyrolysizing, efficient improving electron transfer capability. By staged replacement of electrodes, showering engineering bacteria and auxiliary agents onto site(s), the sintered iron-rich biochar, which enriches iron in an iris, mediates extracellular electron transport of engineering bacteria and promotes the process of reducing dehalogenation of persistent halogenated organic pollutants. The present invention is particularly pronounced for emergency remediation and treatment of halogenated organic pollutants at halogenated contaminated sites with removal rates of more than 95%.
