Partitioning of Toxic Organic Compounds on Municipal Wastewater Treatment Plant Solids

摘要

Fundamental aspects of partitioning of toxic organic compounds on municipal wastewater treatment plant solids have been investigated. Sorption on wastewater solids was not affected by solids-to-liquid ratio. Kinetic data on sorption showed an initial rapid uptake followed by a slower rate over an extended period of time. Freeze-dried solids did not exhibit the same sorption characteristics as viable biomass. A correlation between sorption of toxic organics on wastewater treatment plant solids and the octonal/water partition coefficient has been established. The correlation should be useful for estimating the removal of toxic compounds in wastewater treatment plants by the sorption mechanism.
