摘　　要：氨法生产碱式氯化锌后,母液中含有氯化锌、氯化铵等,直接排放会污染环境及造成资源的浪费。作者开发出一套从碱式氯化锌生产母液中回收饲料级氧化锌粉末的方法,既能实现碱式氯化锌生产母液的高值化利用,又能降低生产氧化锌的能耗。After producing the basic zinc chloride through ammonia process,which mother liquor contains zinc chloride,ammonium chloride,et.If the mother liquor discharges directly,that will cause environmental pollution and wasting of resources.The author developed a new method of recovering feed grade zinc oxide powder from the mother liquor of basic zinc chloride.The method can achieve the aim of high valuable utilization of the mother liquor,and reducing energy consumption of the zinc oxide production.

关 键 词：碱式氯化锌母液 直接回收 饲料级氧化锌 低能耗
