Abstract

In this work, it is studied the aerobic degradation of 2,4,6-trichlorphenol (2,4,6-TCP) that appears during the process to obtain cellulose stuff by means of chlorine and chlorine dioxide. The presence of co-substrate does not mean any additional advantage with regard to the degradation rate and extent. It is observed that effluents with 2,4,6-trichlorphenol 150 mg/L concentrations can be effectively degradated if there is an appropiate biomass, nutrients are proportioned and there is an appropiate aireation.
