1. Concentrated evaporation treatment method. Advantages: Large processing capacity, low water quality requirements for treatment; Disadvantage: High operating costs.
2. Membrane permeation treatment method. Advantages: The principle is simple and only applicable to the treatment of small amounts of high salt wastewater; Disadvantage: The equipment is delicate, prone to blockage and pollution, and cannot handle a large amount of wastewater.
3. Electrolytic desalination method. Advantages: The principle is simple and only applicable to the treatment of small amounts of high salt wastewater; Disadvantage: It can only treat salts in wastewater.
4. Salt tolerant bacteria biochemical treatment method. Advantages: Low cost, average effect; Disadvantage: It has strict requirements for water quality treatment and is greatly affected by organic matter in wastewater. As far as current technology is concerned, only the concentrated evaporation treatment method can effectively treat high salt wastewater.
