介绍了中国黄金集团夹皮沟矿业有限公司干堆氰化尾矿雨季淋溶液的来源与性质，研究了采用空气源间歇批处理臭氧氧化工艺进行深度处理的应用实践。试验研究结果表明，处理后废液中污染物含量平稳，总氰化合物质量浓度低于0．2 mg/L、COD质量浓度低于50 mg/L。该研究项目进入生产运营期后，按额定设计运行，每年可减排总氰化合物2．53 t、COD 3．15 t。
@@@@The paper introduced the source and nature of leaching liquor from dry stack of cyanide tailings in Jia-pigou mining company in rainy seasons and studied the application practice of intermittent batch treatment and ozone oxidation process using air source to intensively treat the liquor .The results show that after treatment,contents of pollu-tants in the effluent are steady with total cyanide less than 0.2 mg/L and COD concentration less than 50 mg/L.When the research project is put in production ,it is expected that every year 2.53 t cyanide and 3.15 t COD are spared from emission.
