Abstract

The invention relates to the technical field of wastewater treatment, in particular to a system and method for treating wastewater containing sodium chloride. The system for treating wastewater containing sodium chloride comprises a crystallization centrifugal separation system and is characterized in that the crystallization centrifugal separation system comprises a hydrocyclone, a thickener and a centrifugal machine which are sequentially connected, wherein the hydrocyclone is connected with a triple effect evaporation device used for concentrating wastewater containing the sodium chloride. The system has the beneficial effects of realizing zero emission of the wastewater, reducing negative effects of salt-containing wastewater emission on local surface water body and agricultural production, recycling a large quantity of steam condensate and sodium chloride, realizing win-win targets of economic benefit and environmental protection benefit, reducing consumption of live steam and lowering operation cost, and has a wider application prospect in the high-salinity wastewater treatment project.
