Background: A large amount of saline wastewater is generated during the production of lithium batteries, such as wastewater from raw materials such as manganese sulfate and cobalt sulfate, as well as high salinity wastewater generated during the production of ternary materials and lithium iron phosphate.

Solution: Use MVR evaporator to treat lithium battery wastewater. The wastewater first passes through the preheating system and then enters the MVR forced circulation evaporator for evaporation. The secondary steam generated by evaporation undergoes defogging, heating, and condensation to recover heat, which is then used for preheating the system. Finally, the salt in the wastewater precipitates in the form of crystals, and the mother liquor is returned to the preheating system for recycling.
Effect: This process achieves zero discharge treatment of lithium battery wastewater, while recovering salt from the wastewater, reducing production costs, and improving resource utilization efficiency.
