Toxic Organic Volatilization from Land Treatment Systems

摘要

Methodology was evaluated for estimating volatilization of toxic organic chemicals from unsaturated soils. Projections were compared with laboratory data for simulated rapid infiltration wastewater treatment systems receiving primary municipal wastewater spiked with a suite of 18 toxic organic compounds, nine of which were considered volatile. Predictions within a factor of 2 were possible under the quasi-steady state conditions of the experiment for most compounds applied. Volatilization was calculated by applying Fick's second law under the experimental conditions.
