Compost decontamination of soil contaminated with PCB using aerobic and anaerobic microorganisms

摘要

The present invention provides a process of decontaminating, by composting under specific conditions, soil and/or sediments containing toxic contaminants of PCB. The process is carried out by converting the contaminants into harmless materials. The process includes the step of affecting a solid compost mixture during composting with a redox potential below negative 200 mV (millivolts). Further, the process includes several steps which are repeated until complete degradation is achieved. Other processes for degrading compounds such as chlordane, dieldrin, toxaphene, aldrin, endrin, and heptachlorepoxide as well as polychlorinated benzenes are also disclosed.
