Abstract:

The source,water quality characteristics and hazards of high-salt wastewater were introduced,and the principles,research and application progress of high-salt wastewater treatment technologies such as thermal concentration treatment technology,membrane separation treatment technology,membrane concentration treatment technology,and combined treatment technology were systematically analyzed.By comparing the advantages and disadvantages of different high-salt wastewater treatment technologies,it was concluded that the key to the development of high-salt wastewater treatment technology was to make full use of latent heat or develop clean energy,prepare or improve new anti-pollution membrane materials,extract and domesticate halotolerant bacteria and halophilic bacteria.It was proposed to simplify the treatment process,speed up the research and application of coupling technology,and develop new efficient and environmentally friendly treatment materials as the development direction of high-salt wastewater treatment technology.

Key words: high-salt wastewater, treatment process, combined process
