    摘要
  • 摘要: 通过多批次的小试试验考察了结晶沉淀-树脂吸附组合工艺对黄连素含铜废水的处理效果,并对产生的碱式氯化铜(TBCC)结晶沉淀进行X射线衍射(XRD)成分分析。结果表明:反应pH为7.0~9.0时,废水中超过99.9%的Cu 2+以碱式氯化铜结晶沉淀的形式得以回收,反应生成的碱式氯化铜沉淀通过水洗后,其成分符合GB/T 21696—2008《饲料添加剂 碱式氯化铜》质量标准。剩余的废水再经过树脂吸附工艺处理后,出水Cu 2+浓度小于1.0 mg/L。在小试试验的基础上,开展了中试试验研究,其结果进一步验证了小试试验的运行效果及该工艺的可行性。通过该处理工艺既可综合利用废水中的铜资源,又可将废水的pH由小于1调至大于7,有利于实现制药废水综合处理和达标排放。

     

    Abstract: A combination of crystalline precipitation and resin adsorption process was adopted for the recovery of copper contained in berberine production industrial wastewater. Optimized conditions were studied by batch experiments. The crystal structure of produced precipitate as tribasic copper chloride (TBCC) was evaluated by XRD analysis. The results showed that under the pH of 7.0-9.0, over 99.9% copper was recovered by crystalline precipitation process. The composition of basic copper chloride precipitation could meet with national standards(GB/T 21696-2008) of feed-grade after water washing. After a following ion exchange treatment the effluent copper ion concentration was less than 1.0 mg/L. On the basis of the bench-scale test, a pilot scale test was carried out. The results of pilot scale tests certified the effect of this combined process. This process could recover the copper resource from pharmaceutical industrial wastewater and, at the same time, improve the pH from lower than 1 to higher than 7, which would be beneficial to the comprehensive treatment of pharmaceutical wastewater and the meeting of discharge standards.
