FIELD: technology of cleaning industrial waste water from ions of heavy metals, including chromium (VI). SUBSTANCE: waste water containing ions of heavy metals and chromium (VI) is subjected to single-stage galvanochemical treatment followed by correction of pH, heating, keeping at high temperature and separation of finely-dispersed crystal sediment of flow volume. EFFECT: reduced volume of separated sediment at retained high efficiency of cleaning; reduced wash-out of ions of heavy metals from sediment. 3 ex
