Abstract

The invention discloses an intelligent desalting system for mine water. Through the coordination effect of a first-stage deep treatment system, a second-stage deep treatment system, an intelligent evaporation and crystallization system and a solid waste treatment system, the intelligent desalting system which performs intelligent regulation and control in real time on line and is simple to operate and good in pollutant interception effect is formed. Compared with treatment conditions of original mine water pretreatment systems, the intelligent zero-emission mine water treatment system has the advantages that 29 indexes of the effluent quality meet the requirements of surface water environment quality standard III-class water, the discharged salt content does not exceed 1000 mg / L, and the functions of upstream and downstream related river reach water are not affected. By-products can produce industrial I-class first-grade sodium sulfate with the purity of more than or equal to 99.0% and industrial dry salt second-grade sodium chloride with the purity of more than or equal to 97.5%, sludge produced by the system can be subjected to landfill treatment, carnallite produced by the system is mixed with fly ash to serve as building material filler, and zero emission of mine water is basically achieved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an intelligent desalination system for mine water. Background technique [0002] In recent years, with the gradual improvement of people's understanding of water environment protection and rational allocation of water resources, various competitive water use has been coordinated, effective management of water resources has been strengthened, and polluted water bodies have been efficiently purified through water treatment projects to supplement the basic production water supply. It strengthens the regulation and control capacity of water resources, which is of great benefit to promote the sustainable development of the region. At present, with the comprehensive promotion of green mine construction, the effective treatment and rational utilization of mine water has become the focus of the government's attention. [0003] Due to the relatively large displacement and relativ...
