measuring and modelling voc biotransformation rates

摘要

A new protocol was used to determine biotransformation rate coefficients for volatile organic compounds in activated sludge systems. The values obtained from the protocol were compared to biotransformation rates obtained from a pilot plant. It was seen that biotransformation rates were easier to obtain from the protocol. Observations also showed that acclimation of the microorganisms to the volatile organic compounds did not change the biotransformation rates. The experimental conditions were then modelled using TOXCHEM, a mechanistic model, to predict volatile organic compound behaviour.
