METHOD FOR PURIFICATION OF INDUSTRIAL WASTEWATERS FROM POLLUTION PRODUCTS AFTER APPLICATION OF METAL COATINGS

摘要

A method for purification of industrial wastewaters from pollution products after application of metal coatings in bathes comprises preliminary decrease in concentration of metals and pollutions in industrial wastewaters by a mechanical method. Pieces got from the metal coating bathes containing film of electrolyte with ion metals on the surface are washed in catching bathes, then in the washing bathes. The water from the bath to bath is directed in the direction of filling thereof. The pure water is passed for pieces rinsing in the last washing bath. Thereafter, the washing water remained from filling the bath of metal coatings is passed through the biofilter, in which preliminary the strains of microorganism: Aeromonas dechromatica KC-11, Desulfoviibrio desulfuricans, Mikrococcus, Mycobakterium spp, Achromobacter guttatus, Achromobacter per oxy dans, Achromobacter suboxydans, Bacterium imperiale, Citrobacter freundii, Flavobacterium diffusum, Pseudomonas aeruginosa, Pseudomonas membranoformis, Serratio marcesc are introduced.
