Zoria D. Integrated treatment of industrial wastewater from copper

The dissertation is devoted to the study of technologies and methods that increase the efficiency of industrial wastewater treatment from copper with waste disposal, obtaining valuable raw materials and organizing closed water supply systems. The theoretical justification of the solution cleaning process is given; containing copper, cementation and ferritization. A mathematical model of the process of cleaning solutions containing copper is presented. A series of experimental studies of the processes of copper cementation in a reactor loaded with iron powder and the second stage of purification-ferritization was carried out, the results were analyzed. The composition and physicochemical properties of precipitates obtained during water purification by ferritization are investigated. A technique has been developed for the engineering calculation of the main technological parameters and characteristics of the process of copper extraction from wastewater. A complex technology of water purification from copper to produce marketable products is proposed. A feasibility study of integrated wastewater treatment technology has been carried out, technological schemes have been proposed. Key words: wastewater, copper, iron, cementation, ferritization, treatment effect.
