摘要

介绍了国投金城冶金有限责任公司冶炼烟气制酸装置污酸污水减排的措施和实际效果。技术人员将环集烟气洗涤污酸送入冶炼烟气净化斜沉池,用于冶炼烟气的净化洗涤水,减少污酸排放;将循环冷却水由闭路循环变为半开路循环,现场所有机泵冷却水由长流水改为循环水,不再外排浓缩循环废水。改造后硫酸厂污水处理量每天维持在500 m~3左右。
        Measures and practical effects of waste acid and wastewater reduction in metallurgical acid plant of Guotou Jincheng Metallurgical Co., Ltd. are introduced. Technical staffs transported waste acid purifying circumfluence flue gas into oblique sink for metallurgical off-gas purification to be purifying washing water for metallurgical off-gas, reduced waste acid emission, changed circulating cooling water closed loop into semi-open loop, and long flowing water for all pump cooling water on site into recycled water without discharged concentrated circulating wastewater. After transformation, sewage processing capacity in acid plant kept about 500 m~3/d.
