USE OF THE PROCESSED GALVANIC SLIMES AS ONE OF THE RECYCLING OF TECHNOLOGIES

Abstract

The analysis of a situation in the sphere of galvanic production recycling is presented in work. Galvanic production is one of the most dangerous sources of environmental pollution. Mainly superficial and under-ground sources are soiled. It occurs because of the large volume of the sewage containing harmful impurity of heavy metals, inorganic acids and alkalis, surfactants and other highly toxic connections and solid waste is formed. Especially because a reagent way of the sewage containing heavy metals in a slightly soluble form. Assessment of harm of chemical components of galvanic slimes is presented. The possibility of slimes processing by hardening in concrete mix as a part of paving slabs is considered. The paving slabs with use of slimes as the painting pigment is offered. The order of carrying out tests for definition of galvanic slimes safety using for production of construc-tion materials (paving slabs) is given. Influence of slimes introduction on mechanical properties of products is shown. The dependence of products color on amount by the entered galvanic slime and possibility of color schemes correction are shown.
