Method for Treating Wastewater Containing Copper Complex |
摘要 |
Disclosed is a method for treating wastewater containing at least one copper complex, comprising: 1) providing the wastewater containing the at least one copper complex, wherein the at least one copper complex is chosen from EDTA-Cu2+ complex and ammonia-Cu2+ complex; 2) adjusting pH of the wastewater containing the at least one copper complex to be within a range from 2.0 to 3.0, and adding ferrous sulfate to convert copper in the wastewater into a form of cuprous ions; and 3) adjusting pH of the wastewater obtained in step 2) to be within a range from 8.0 to 10.5, so that the cuprous ions in the wastewater are converted into precipitates of cuprous hydroxide and/or precipitates of cuprous oxide.
