A copper smelting high-arsenic waste acid treatment system

Abstract

The utility model discloses a copper smelting high arsenic contaminated acid processing system, including one section sulphidation system, two section sulphidation system, post -treatment system, its characterized in that still including three section sulphidation system, three section sulphidation system is located between two section sulphidation system and post -treatment system, three section sulphidation system includes three section sulphidation reaction tank, sulphidation intermediate storage tank, sulphidation filtration precipitation tower connected in order, still including three section filter press, two section sulphidation system's export end connects three section sulphidation reaction tank's import end, and sulphidation filtration precipitation tower's export end connects post -treatment system's import end and three section filter press, three section filter press's export end connects post -treatment system's import end. The utility model has added three section sulphidation system between two section sulphidation system and post -treatment system, has improved copper smelting high arsenic contaminated acid sulphidation efficiency, reaches the wastewater after contaminated acid treatment, gypsum residue reaches the general solid waste standard, satisfies the processing demand of high arsenic contaminated acid.
