Comprehensive treatment method for iron-containing acidic water

The invention provides a comprehensive treatment method for iron-containing acidic water, and relates to the field of water treatment. According to the method, iron-containing acidic water is sequentially subjected to iron removal pretreatment, sulfuration copper recovery and neutralization treatment, during iron removal pretreatment, iron removal turbid liquid is directly input into a sulfuration copper recovery section without flocculation, and meanwhile, an oxidizing agent is used for treatment in the neutralization process, so that neutralization overflow and press filtrate obtained in the neutralization process can meet the emission standard; the deep purification of the iron-containing acidic water is realized; no iron slag is generated in the process, the generation amount of solid waste is greatly reduced, the valuable substance copper lost along with the iron slag liquid phase is effectively reduced, and the copper recovery rate of the whole acidic water treatment system is improved. Through the mode
