METHOD OF TREATMENT OF SEWAGE CONTAINING COPPER IONS

摘要

metallurgy, ecology. SUBSTANCE: invention relates to utilization of waste containing copper ions from galvanic and other kinds of manufactures and can be used in metallurgy and other kinds of manufacture. Method involves the contact of sewage containing copper ions with natural calcium carbonates followed by treatment of precipitate by live steam, water slaking and granulation. Obtained precipitate is fixed on gypsum- carbonate matrix. Obtained precipitates can be stored for a long time and for the secondary using in nonferrous metallurgy plants. EFFECT: improved and simplified method of treatment.
