FIELD: chemistry.SUBSTANCE: electric processing of sewage waters from ions of heavy metals is carried out by direct current with current density 6-9 A/mand voltage 12 V for 10-15 min; formed sludge, containing ions of heavy metals is lifted to water surface by means of hydrogen bubbles, released on aluminium cathodes, and is removed from water surface.EFFECT: reduction of costs for aluminium and electric energy consumption, increased efficiency and rate of sewage water purification from ions of heavy metals.5 tbl, 4 ex |
