Bioremediation of Diesel Fuel Contaminated Soil in a Rotating Bioreactor Part 2. On-line Monitoring of Pollutants

摘要

Electrochemical and IR sensors as well as mass spectrometer were used to monitor the concentrations of the nalkanes in the off-gas of the bioremediation sludge of the diesel fuel contaminated soil in a rotating drum. The rate constants of the decomposition reactions were evaluated from the concentration courses of the pollutants, and the dependence of the rate constants on the rotational speed of the drum and the gas composition were determined.
