[The treatment of wastes from antibiotic manufacture by using pyrolusite]

Data on laboratory studies with real liquid sewage from antibiotic manufacture are presented. Two schemes are discussed: treatment of the sewage in an electrolysis plant followed by its afterpurification either in a column with pyrolusite or during a joint process of electrochemical purification with catalyst location on the plant bottom under the electrodes. The afterpurification of electrochemically treated liquid sewage on waste pyrolusite can provide and additional effect i.e. lower consumption of oxygen and decoloration at average by 15 and 25 per cent respectively.
