Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a device for treating saline sewage by evaporation. Background Art

[0002] Saline wastewater refers to wastewater containing salts, either from industrial production or daily life. These salts can come from chemicals, salts, or other soluble solids used in industrial processes, or from detergents and table salt used in daily life. The discharge of saline wastewater can have certain impacts on the environment, especially when discharged directly into natural water bodies without treatment. This can cause water pollution and affect the balance of aquatic ecosystems.
