COMPARISON OF BENCH AND PILOT PLANT RESULTS ON THE VITRIFICATION OF U.S. AIR FORCE HAZARDOUS WASTE STREAMS

摘要

The ever increasing disposal costs as well as stringent environmental regulations have necessitated alternative ways of handling hazardous waste. Vitrification technology presents a product based recycling approach to the problem. Five U.S. Air Force waste streams were characterized and a bench scale feasibility study was conducted. Four formulations were developed and subsequently processed through a pilot system. The mass balance and incorporation of hazardous metal from the Seiler high temperature vitrification pilot system have been reported and critically evaluated. Glass-ceramic non-hazardous products were developed with spinel and augite phases in a glass matrix. The products had critical performance properties. The effect of salt content and waste variability have been studied and some solutions have been recommended.
