METHOD AND DEVICE FOR ELECTROLYTICALLY REMOVING AND RECOVERING METAL IONS FROM WASTE WATER

摘要

The present invention relates to a method for removing and recovering metal ions from various kinds of waste water to be treated. The method comprises an oxidizing agent removing apparatus for decomposing and removing an oxidizing agent from the water, and an electrolytic deposition apparatus ( 21 ) for removing and recovering metal ions from the water discharged from the oxidizing agent removing apparatus. The electrolytic deposition apparatus has electrodes and an ion exchanger disposed between the electrodes.
