Chemical precipitation is preferred for treating fluorine-rich wastewater. Biological method is the main treatment process of nitrogen-rich wastewater.
In conclusion, current research on PV cell production wastewater remains in its exploratory stage. For fluorine-rich PV wastewater, the combination of chemical precipitation and coagulation sedimentation processes is still the predominant approach. However, more research efforts are needed in CaF 2 resource recovery.
When it comes to recycling, a combination of physical separation, thermal, and chemical treatments is currently the most effective approach. These methods allow for the recovery of valuable materials and reduce the environmental footprint associated with PV waste.
