摘　　要：针对化学合成制药含铜黄连素废水特点,设计了铁碳微电解和离子交换组合工艺为预处理工艺,开展了小试与中试试验研究。结果表明,采用铁碳微电解池-离子交换柱组合工艺连续处理初始CODCr浓度为60 000-80 000 mg/L、黄连素浓度为1 700-1 900 mg/L、Cu2+浓度为12 000-18 000 mg/L的含铜黄连素制药废水,小试试验对黄连素和Cu2+的去除率都在99.0%以上,出水黄连素和Cu2+在1.0 mg/L和0.5 mg/L以下。中试试验对CODCr的去除率在44.0%以上,Cu2+的去除率超过79.0%。处理每吨水可回收12～13 kg铜。该工艺有较好的废水预处理效果,实现了金属铜资源化回收,可有效减少对后续废水生化处理工艺的压力。For the copper-containing berberine wastewater produced by pharmaceutical chemosynthesis of Liaohe River, the Fe-C microelectrolysis reactor-ion exchange column combined process was selected accord- ing to the the characteristics of the wastewater. The lab- scale and pilot- scale pretreatments were carried out. The results showed that for the influent wastewater with chemical oxygen demand （COD） concentration of 60 000- 80 000 mg/L, copper concentration of 12 000-18 000 mg/L, berberine concentration of 1 700-1 900 mg/L, the removal efficiencies of berberine and Cu^2＋ were higher than 99.0 %, and the concentration of berberine and Cu^2＋in effluent were lower than 1.0 mg/L and 0.5 mg/L after lab scale experiment. For the pilot scale experiment, the CODcr removal efficiency is higher than 44.0 %, while Cu^2＋ removal efficiency is higher than 79.0 %. 12-13 kg bronze per ton wastewater could be recovered. The Fe-C microelectrolysis reactor-ion exchange column combined process showed good pretreatment effect and released the pressure of biological wastewater treatment in the next stage.
