Abstract: To dechlorinate perchloroethylene (PCE), batch experiments were conducted for five groups of reactors: zero-valent iron (Fe⁰), zero-valent zinc (Zn⁰), an anaerobic microbial community (MB), a combination of iron powder and an anaerobic microbial community (FeMB), and combination of zinc powder and an anaerobic microbial community (ZnMB). After about 25 days, PCE in the FeMB degradation system has been almost completely removed; about 43% of PCE has been dechlorinated to the nontoxic hydrocarbons acetylene, ethylene or ethane. This major reaction pathway in the FeMB system was different from those in other systems. The chain pseudo-first-order kinetic reaction model was applied to predicting the complete dechlorination of PCE to non-chlorinated hydrocarbons in different systems.
