High salt wastewater is mainly divided into high salt organic wastewater and high salt inorganic wastewater. High salt wastewater is generated through a wide range of pathways, and the amount of water is increasing year by year. The discharge of high salt wastewater has a huge impact on the environment, so pollutants in the wastewater must be removed before discharge. The commonly used methods for treating high salt wastewater include the following: salt tolerant bacterial biochemical treatment, traditional evaporation and concentration equipment evaporation, membrane technology desalination, and electrolytic desalination. However, due to the toxic and inhibitory effects of high salt, the implementation of biochemical treatment technology has encountered great obstacles; Traditional evaporation and concentration equipment has high operating costs and low energy efficiency; Membrane technology treatment equipment is expensive, prone to clogging, pollution, and ultimately produces concentrated liquids that cannot be processed; The electrolysis method is usually unable to electrolyze due to issues with organic matter.

With current human technology, the most ideal way to treat high salt wastewater is to use energy-saving evaporation technology. Jiejing Energy has developed an MVR energy-saving evaporation device that can achieve solid-liquid separation and standard reuse of condensed water based on the characteristics of high salt wastewater. The working process is as follows: low-temperature steam is compressed by a compressor, the temperature and pressure increase, the enthalpy increases, and then enters a heat exchanger for condensation. The released heat is provided to the material for heating and evaporation, fully utilizing the latent heat of steam. This MVR evaporation and concentration system uses electricity throughout the entire evaporation process and does not require steam generation.
