[0002] High-salt wastewater refers to wastewater in which the mass fraction of total dissolved solids (TDS) in the water body is greater than or equal to 3.5% (some say it is 1%). In addition to organic pollutants, this type of wastewater also contains a large amount of soluble inorganic salt ions such as calcium, magnesium, sodium, chlorine and sulfate, and even radioactive substances.
