中文摘要: 采用聚合硫酸铁(PFS)法处理镍钼矿酸浸液萃钼余液中的重金属离子和化学耗氧量(COD),考察双氧水用量、PFS用量、搅拌时间、pH对余液中Zn2+、Pb2+、Ni2+及COD含量的影响。结果表明,在双氧水用量20 mL/L、PFS用量60 mg/L、搅拌时间90 min、pH 11.0的条件下,COD可降至500 mg/L以下,去除率高达89%,重金属离子均达到GB 8978-1996污水综合排放一级标准。
Abstract:Heavy metal ions and chemical oxygen demand (COD) in molybdenum extraction raffinate from acidic leaching solution of Ni-Mo ores were treated by polyferric sulfate (PFS). The effects of dosage of hydrogen peroxide and PFS, stirring time and pH value on concentration of Zn2 , Pb2 , Ni2 and COD in raffinate were investigated. The results show that COD concentration can be reduced to 500 mg/L below with removal rate of 89%, and heavy metal ions meet the integrated wastewater discharge standard of GB 8978-1996 under the optimum conditions including dosage of hydrogen peroxide of 20 mL/L, PFS dosage of 60 mg/L, stirring time of 90 min and pH value of 11.0.
