FIELD: water treatment.
SUBSTANCE: innovation relates to the chemical treatment of industrial and domestic wastewaters containing lubricating and cooling fluids, radioactive contaminating substances, washing solutions, ions of heavy metals; the method includes the decontamination and demulsification of wastewater by the mixture of ferrous chloride (FeCl3), calcium chloride (СаСl2) and permanganate of alkalic or the mixture of alkaline-earth metals at the mass ratio of (1/2):(0.15/0.2):(0.01/0.02) on conversion to arid salts and volume concentration of 1-3% of the initial solution, рН counts to 5-6.
EFFECT: innovation enhances the efficiency of wastewater purification.
