摘要 Anaerobic treatment could effectively degrade organic chlorine. Reductive dechlorination mechanisms were confirmed through GC-MS analysis during anaerobic treatment of pulp bleachery effluents, the influence of sulfide biologically produced and pH on the dechlorination revealed that nucleophilic substitution and alkaline hydrolysis were also nonbiological mechanisms.
