description The invention provides a harmless treatment method for high-copper acidic water treatment residues, and relates to the technical field of water treatment. According to the method, the high-copper acidic water is sequentially subjected to iron removal, sulfuration copper collection, neutralization and harmless treatment of iron slag, so that target heavy metals in neutralization overflow and press filtrate obtained in the neutralization process meet the emission standard, and efficient treatment of the high-copper acidic water is realized; and meanwhile, the iron slag generated in the iron removal process is treated by utilizing neutralizing underflow, vulcanizing liquid or neutralizing liquid generated in the high-copper acidic water treatment process, so that the leaching toxicity and the toxic substance content of the treated iron slag meet the requirements of general industrial solid wastes in a manner of treating wastes with wastes, and the purpose of harmlessness of the produced slag is achieved.
