Full-quantitative treatment system and treatment method for mine wastewater

The invention discloses a full-quantitative treatment system and method for mine wastewater. The invention aims to solve the technical problems of short service life, high energy consumption, low treatment efficiency and substandard effluent of equipment in the prior art. The treatment system comprises: a first solid-liquid separation unit, which is for treating the mine wastewater and outputting a first mother solution; a membrane separation unit, which is used for treating the first mother liquor and outputting permeate and trapped fluid; a first concentration unit, which is used for treating the permeate liquid and outputting sodium chloride-enriched liquid; a first evaporative crystallization unit, which is used for treating the sodium chloride-enriched liquid and outputting sodium chloride crystal salt; a first softening unit, which is used for converting calcium ions and magnesium ions in the trapped fluid into precipitates and outputting a solid-liquid mixture and a supernatant; a second solid-liquid s
