FIELD: industrial sewage purification and extraction of non-ferrous metals during purification of metallurgical production reused waters. SUBSTANCE: apparatus has receiving tank 2, cathode chamber 3 and anode chamber 4 separated by transient partition 5, filtering chamber 8. Cathode chamber 3 and anode chamber 4 are separated from filtering chamber by intermediate chambers 7 and 10 with siphon feeding of water from cathode chamber into filtering chamber and from filtering chamber into anode chamber. Intermediate chambers have regulated thresholds 16, that ar made as sluices or gates. Anode chamber through threshold communicates with discharge chute 11, that is connected with mixing tank 12. Filtering chamber is divided by filtering device 13 for two equal tanks 14 and 15. EFFECT: apparatus allows to purify industrial waste waters and to extract non-ferrous metals from it. 5 cl, 1 dwg
