Wastewater Containing Copper Precipitation Research

With copper wastewater as the research object, in sulfide - flocculation process, a comparative study of its wastewater treatment of copper sulfide dosage, type of flocculation, flocculation dosage, stirring time and other conditions. The results show that: in their respective optimum conditions, the flocculation PAC than PFS to pH adaptability, low dosage, copper removal rate reached 97.7%, the reaction solution pH value of 6.5, to achieve "Integrated Wastewater Discharge Standard" (GB8978-1996) emission standards.
