Research of Mechanisms of Copper Ions Removal out of Sewage of Machine-Building Productions by Combined Reagent Based on Industrial Wastes

Abstract

The need for sewage purification of machine-building production from copper compounds which possess toxic, allergic, cancerogenic, gonadotropny and embryotoxic action, has been justified. The methods of studying of component and mineralogical composition of wastes, which are used for purification of model mortars, have been given. Some methods of purification of mortars from copper ions have been considered. The need for the search of alternative methods of purification, taking into consideration the composition and properties of the purified environments, and also taking into account the possible reset of purified sewage into natural reservoirs, has been shown. It has been revealed, that application of calcium- containingwaste as reagent won't help to additional alkalization of natural reservoirs. Prospects of use of regional industrial wastes for extraction of copper ions out of model mortarshave been shown. The mechanism of purification of model drains from copper ions by a combined reagent has been described.
