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60000~80000 mg/L、黄连素浓度为1700~1900 mg/L、Cu2+浓度为12000~18000 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 Cu2+were higher than 99.0%,and the concentration of berberine and Cu2+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 Cu2+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.
