发明名称 Sludge disinfection
摘要 Disinfection and flocculation of waste activated sludge from a bio-oxidation facility is achieved by contacting the activated sludge with zinc salts optionally in the presence of manganese salts. Either simultaneously with the addition of the zinc or after the addition, sufficient base must be added to render the solution basic.
