Environmental safety evaluation from galvanic sludge during long-term storage

Tretiakova Larissa, Mitiuk Ludmila

Journal of New Technologies in Environmental Science

2020

Vol. 4, nr 3

105--113

The article analyses the ecological state of the soil in an enterprise with a galvanic shop that produces chips and microcircuits. The problem of production waste storage in open areas is investigated. Environmental hazards during long-term storage of sludge have been identified. The composition of the sludge obtained after sewage treatment of the production of the copper line was investigated. A method for predicting the level and depth of soil salinity during long-term sludge storage is proposed. The experience of reuse of copper extracted from sludge is analysed.
