(Summary description)The COD of the wastewater is 200 ~ 3000mg / L, and some organic molecules in the wastewater affect the technical indexes of the recycled water. At the same time, the cost of the advanced treatment of organic wastewater is high. U key technology bentonite based modified adsorption material complete set preparation technology bentonite based modified adsorption material selective adsorption technology and recycling technology u application effect selective adsorption of organic molecules unfavorable to mineral processing operation, while retaining organic molecules favorable to mineral processing operation, reducing the dosage of mineral processing agent, achieving the effect of improving both grade and recovery. The operation cost of the advanced treatment of mineral processing wastewater is low, and the COD in the discharged water can be reduced

u 选矿废水性质
COD 200~3000 mg/L，废水中部分有机分子影响回水回用选矿作业技术指标，同时有机废水深度处理达标排放成本高。
u 关键技术
Ø 膨润土基改性吸附材料成套制备技术
Ø 膨润土基改性吸附材料选择性吸附技术及再生循环回用技术
u 应用效果
Ø 选择性吸附不利选矿作业的有机分子，而保留对选矿作业有利的有机分子，减少选矿药剂用量，实现品位与回收率双提高的效果。
Ø 选矿废水深度处理运行成本低，排放水中COD可降至20mg/L以下，达到地表水III类水排放标准极限值。
u 成果
Ø 获2015年青海省科技进步二等奖
Ø 获2015年龙岩市科技进步三等奖
Ø 获2015年黄金协会科学技术奖三等奖
Ø 获2014年龙岩市专利奖三等奖
