This equipment is suitable for industries such as pharmaceuticals, biotechnology, food, and chemicals, primarily for the terminal treatment of saline wastewater, making it a common device in environmental protection systems. Tailored for the characteristics of high salt content and high concentration in chemical organic wastewater, it operates based on the principle of evaporative concentration and crystallization under reduced pressure to treat organic wastewater. After separating the salt from the concentrated liquid and recovering it through a salt collector, the concentrated liquid can be dried for recovery or subjected to incineration treatment. The condensed water after evaporation generally undergoes subsequent biochemical treatment to achieve standard discharge of wastewater.
