Behavior of Organic Pollutants during Rapid-Infiltration of Wastewater into Soil: 1. Processes, Definition, and Characterization Using a Microcosm

摘要

A microcosm was constructed to study the behavior of organic pollutants during rapid infiltration of municipal wastewater into soil. The microcosm permitted a direct measure of the amount of volatilization and allowed calculation of the amount that degraded. The wastewater was amended with selected organic compounds at individual average concentrations of 0.2 to 32 micromoles/L. Chloroform, 1,1-dichloro-ethane, 1,1,1-trichloroethane, trichloroethene, and tetrachloroethene volatilized extensively. There was observable degradation of 1,1-dichloroethane but there was no detectable degradation of the other volatile compounds.
