[0002] A large amount of reclaimed water will be produced in the process of copper smelting, and the copper mine acid wastewater treatment system will also produce some reverse osmosis concentrated water with high salt content. The water quality has high calcium, magnesium, sodium, chlorine, nitrate, and sulfate , bicarbonate plasma, higher total dissolved solids, a small amount of heavy metal ions, and some suspended solids and organic pollutants. The water is currently using traditional purification and concentration processes. Although part of the reclaimed water can be recovered, the concentrated water that can be discharged will be recycled. pollute the environment

Embodiment
[0039] The water treatment system supporting the industrial upgrading and transformation of a copper industry limited company.
[0040] 1. introduction
[0041] The supporting water treatment system includes water reuse system, desalinated water system and concentrated brine zero discharge system.
[0042] The design water intake of the reuse water system is the drainage of the circulating water system, and the water intake is 4416m 3 / d, which is 184m 3 / h. Adopt the process of mechanical stirring clarifier (including lime, soda ash softening) + multi-media filter + self-cleaning filter + ultrafiltration + first-stage reverse osmosis + concentrated water reverse osmosis, concentrated water collected by concentrated water reverse osmosis device enters concentrated brine Zero discharge system treatment.
[0043] The desalinated water system uses the water produced by the reuse water system as the water source, which is used by the owner's waste heat power generation boiler...

The invention provides a copper smelting reclaimed water treatment and recovery device and a zero emission method. The recovery device structurally comprises a pretreatment softening system (1), a primary desalination treatment system (2), a secondary desalination treatment system (3) and a strong brine zero emission treatment system (4). The zero emission method for copper smelting reclaimed water treatment and recovery includes the following steps of 1 pretreatment softening, 2 primary desalination treatment, 3 secondary desalination treatment and 4 strong brine zero emission treatment. The copper smelting reclaimed water treatment and recovery device and the zero emission method have the advantages that the water hardness is removed by using lime and calcined soda; primary desalination is performed by utilizing primary reverse osmosis, and effluent is supplemented to circulating water; further desalination is performed by utilizing secondary reverse osmosis and electrodeionization to meet the brine removal requirement; concentration, reduction and evaporation are performed by utilizing special reverse osmosis; (5) finally water resources are recycled, and the purposes of pollution and zero emission are eliminated.
