Influence of time Variation of Phenols and organic matter on the degradation Capacity of bacterial biota in an anaerobic Plug flow reactor

Abstract

This investigation proposes an anaerobic treatment system responsible for reducing the pollutant loads that are present in the waste water generated by the veterinary clinic of the Universidad de La Salle, by means of the direct action of the microbial activity exerted by the bacteria contained within the inoculated mud in the plug flow anaerobic reactor (RAP), designed for such goal. Establishes too the required actions to maintain steady the operation of the RAP in regard to the contribution of the methanogenic bacteria and sulphate reducers, by means of the development of laboratory analysis and the determination of in situ parameters, which allows to define the environmental factors that affect the behavior of the bacterial biota of the reactor and at its time the capacity of degradation of organic compounds presented by them. Finally, a part of the verification demonstrated that the increase in the Phenol concentrations in the affluent of the RAP could destabilize the anaerobic processes due to the inhibition of the methane production by the bacteria present in the reactor, due to this compound is considered as toxic and when is used as substrate in the anaerobic digestion processes causes imbalance in the bacterial metabolism
