FIELD: final purification of waste waters. SUBSTANCE: method involves filtering waste waters through sulfuric packing at a first step and through activated charcoal at a second step with further regeneration of sulfuric packing and activated charcoal. The method is characterized in that regeneration of sulfuric packing is effected by keeping the packing under column of water with further natural or forced aeration or by treating the sulfurizing packing with hydrogen sulfide containing gas with further aeration. EFFECT: enhanced efficiency. 2 tbl
