Application Prospects of MVR Systems in the Treatment of High-Salinity Wastewater from Nuclear Power Plants

With increasingly stringent environmental protection requirements for nuclear power plants, the treatment of high-salt and high-ammonia-nitrogen wastewater from non-radioactive production wastewater has become one of the technical challenges. The MVR (Mechanical Vapor Recompression) system designed by Jiangsu Gaojie Group, as a highly efficient and energy-saving evaporation and concentration technology, has broad application prospects in the treatment of high-salt wastewater from nuclear power plants.
MVR systems significantly reduce energy consumption by recovering the latent heat of secondary steam and are suitable for treating high-salinity wastewater discharged from condensate polishing systems. This type of wastewater has a high salt content (5000~10000 mg/L) and is characterized by intermittent discharge and unstable flow. MVR systems can concentrate and reduce the volume of wastewater, thereby reducing the load on subsequent treatment processes, while simultaneously recovering high-quality distilled water, achieving resource utilization of the wastewater.
Compared to traditional treatment methods, MVR systems offer advantages such as low operating costs, small footprint, and high automation, making them particularly suitable for new nuclear power plants or retrofit projects with sufficient space. Combined with ammonia nitrogen removal technologies such as stripping or membrane desulfurization, MVR systems can provide an integrated solution for the compliant discharge and resource recovery of non-radioactive production wastewater from nuclear power plants.
