摘要: The efficiency of removing trichloroethylene (TCE) using co-immobilized zero-valent iron and autotrophic hydrogen-bacteria has been studied in this research. Laboratory results show that the combined physicochemical biological system is much superior to either or alone dechlorination TCE. In addition catalyzed hydrogenolysis reactions occurring between hydrogen gas particle surface, as well hydrogen-bacteria, FeS produced by sulfate-reducing bacteria also contributes catalytic mechanisms. presence gas, corrosion powder somewhat alleviated, thus extending useful life for treating pollution. membrane feeding substrate bioreactor (MFSB) reveal TCE removal rate 3.5 times faster than method, 5 treatment method potential clean up sites contaminated chlorinated hydrocarbons demonstrated presented paper.
