TREATMENT OF AQUEOUS PHOSPHORUS WASTES

摘要

Aqueous phosphorus wastes from the electric furnace production of phosphorus and containing heavy metal bearing particulates are treated with lime whereby the phosphorus is converted into useful phosphorus compounds and the heavy metals rendered sufficiently non-leachable to permit their release into the environment. The treatment is conducted above about 60 DEG C at a pH of between about 11.0 to 12.5.
