摘　　要：采用新型反应器及胶凝除硅、直接酸溶重结晶、直接煅烧等技术对二氧化锆的生产工艺进行了改革 ,降低了原材料消耗及能耗 ,减少了废液排放量 ,并将回收的废物加工成副产品白炭黑 ,在生产过程中防治污染。Some new technological measures,such as new reactors,gel method to remove silicon,direct dissolve acid to recrystallizate and direct calcine from zirconyl chloride,were used to reform zirconium dioxide production process.As a result,the materials consumption and energy consumption were reduced and the wastewater discharge was decreased.Meanwhile the rubbish were recovered and utilized to prepare into a by product as silica aerosol.The pollution prevention and control in production process were achieved.
