Kolodko A. Ecologically safe processing of toxic waste from galvanic industries

The work is devoted to the development and implementation of reliable low-waste and energy-saving methods, which allow efficient removal of heavy metal ions from galvanic sediments and wastewater, create closed systems of water supply with disposal of environmentally friendly sludge. Management solutions in the field of ecological monitoring and management of galvanic waste are proposed. As a result of experimental studies, the feasibility of using electromagnetic pulse discharges to activate the process of galvanic waste processing by ferritization is justified. The influence of the basic technological parameters of galvanic waste processing on the degree of heavy metals extraction and the physical and chemical properties of ferromagnetic sediments have been experimentally investigated.An energy-efficient ferritization reactor was designed and innovative integrated technological scheme for galvanic waste processing with an improved ferrite method was developed, which reduces the negative impact on the environment as a result of the disposal of toxic waste and implementation of closed water supply on-site, as well as significant reduction of energy and reagents consumptions with ability of automatically operation control of compact technological equipment.
