Ji Y., Guo H., Zhang T., Liu J., 2018, Ultrasound-Assisted Copper Foam/H2O2 System for Treatment of Printing and Dyeing Wastewater, Chemical Engineering Transactions, 67, 535-540.
Ultrasound-assisted copper foam/H2O2 system was used to pretreat printing and dyeing wastewater (hereinafter as the wastewater). Before and after the treatment, the chromaticity and the change of B/C of the wastewater were investigated respectively. The results showed that the system can quickly remove the chromaticity of the wastewater in a short period of time. The B/C of the wastewater was significantly increased, improving the biodegradability of the wastewater. In addition, the UV-vis scanning and GC-MS analysis of the wastewater before and after the treatment were carried out to further analyze the treatment effect of the system on the wastewater.
