In the treatment of saline wastewater, evaporation refers to the process of separating the solvent from the solute in the solution by heating it up. At present, the widely used heating and evaporation technologies include multi-stage flash evaporation technology, low-temperature multi effect distillation technology, and mechanical steam recompression technology. Among them, multi effect distillation technology and MVR technology are commonly used to treat high salt wastewater, among which MVR technology is more energy-saving and energy-saving.
