摘要
采用正交实验研究了微波、超声波条件对废触媒解吸效果的影响,对比实验结果表明,1次微波2次超声波联用技术锌的洗脱率较高,回收的活性炭超过了林业局粉状活性炭二级品指标。用洗脱的醋酸锌溶液制备的磷酸锌符合防锈颜料要求。最终的废液采用电石废渣中和后达到国家废水处理三级排放标准。实现了废触媒的综合回收利用。
The effect of both microwave and ultrasound conditions on desorption of waste catalysts was investigated by orthogonal experiment. Comparison of data revealed that combined action of once microwave and twice ultrasound had a higher zinc extraction, and its decolorization efficiency of regenerated active charcoal to methylene blue was over the second grade of the Forestry Department of China . Zinc phosphate prepared from zinc acetate via desorption waste catalyst in product of vinyl acetate was qualified for the anticorrosive pigment. The waste calcium carbide was applied in the treatment of wastewater, which made discharged water reach the third grade standard of GB. All the results show that multipurpose recovery utilization of waste catalysts can be realized.
