摘要

A process for microbiological purification of water contaminated with chlorinated ethylenes and/or chlorinated propylenes, comprising adding an electron donor and passing the water through a bioreactor containing a syntrophic mixed culture immobilised on a support, where the culture comprises at least one dehalogenating bacterium and at least one hydrogen-producing, strictly anaerobic microorganism.
