摘要

摘要: 采用铁碳微电解池-离子交换柱组合工艺对黄连素含铜制药废水进行预处理中试试验。在投加一定量铁屑和活性炭情况下，考察了中试系统对废水中COD_Cr和Cu²⁺的去除效果，并设计了金属铜回收的工艺流程。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COD_Cr浓度为60 000～80 000 mg/L，初始Cu²⁺浓度为12 000～18 000 mg/L的黄连素含铜制药废水，当铁碳微电解池中铁屑和活性炭投加量均为300 g/L时，铁碳微电解池水力停留时间120 min，离子交换柱水力停留时间60 min，COD_Cr的去除率达44%以上，Cu²⁺的去除率超过79%。使用该工艺处理每t废水可回收铜12~13 kg，实现了金属铜的循环利用。

Abstract: The berberine wastewater containing copper was pretreated by pilot scale Fe-C microelectrolysis reactor- ion exchange column combined process. When a certain amount of iron and activated carbon were added into the reactor, the COD_Cr and Cu²⁺ removal efficiency were tested, and the copper recovery process was designed. The results showed that the berberine wastewater containing copper with initial COD_Cr concentration of 60 000~80 000 mg/L and Cu²⁺ concentration of 12 000~18 000mg/L could be pretreated effectively by Fe-C microelectrolysis reactor-ion exchange column combined process. The COD_Cr removal efficiency was higher than 44% and Cu²⁺ removal efficiency higher than 79% under the conditions of iron and activated carbon dosage being both 300 g/L, the hydraulic retention time (HRT) of 120 min and ion exchange column HRT of 60 min. 12~13 kg bronze per ton wastewater could be recovered, having realized the cyclic utilization of bronze.
