METHOD FOR DISPOSAL CONSIDERATION OF HOUSEHOLD AND INDUSTRIAL WASTE CONTAINING MERCURY

摘要

A method for neutralizing mercury-containing waste, mainly fluorescent lamps, including joint grinding of waste with sulfur powder and a grinding medium in a rotating reactor and binding metallic mercury, characterized in that pyrite of 50-150 mm fraction is used as a grinding medium, which is also a binding agent mercury in ionized and neutral forms, while mercury-containing waste is loaded into a reactor containing a pre-homogenized mixture of sulfur powder, pyrite and water, the volume of which is filled with nitrogen supplied at a rate of 7.5-8.5 m3 / h, in an amount of at least at least 50 times less than the mass of sulfur powder, and grinding is carried out until the complete binding of metallic mercury to a water-insoluble compound HgS.
