摘要：Currently galvanic sludge is considered as one of the most dangerous wastes, which are formed during purification of galvanic wastewater. The slimes of galvanic production are the most toxic industrial waste and sources of heavy metals emitted into the environment. Galvanic sludge belongs to the third hazard class; these wastes need to be deposited in special landfills for toxic waste. These polygons are complex and require significant costs. In this regard, there is a need for such methods of purification of galvanic sewage sludge, which may be used in other industries or will have fourth class of hazard or below. This article compares the main methods of purification of galvanic waste waters in general and galvanic sludge in particular, currently introducing new techniques for treating industrial effluents. One of them considers treatment of galvanic waste water by means of suspensions of ferriferous hydrosol that is an electric generated coagulant derived from waste forming, steel wool, etc. There is a sort of experience already acquired in some countries how to use of ferropericlase.
