Three typical photovoltaic wastewater treatment technologies were described. Chemical precipitation is preferred for treating fluorine-rich wastewater. Biological method is the main treatment process of nitrogen-rich wastewater. The removal method and sequence of pollutants in mixed wastewater need attention.

Summary of actual PV wastewater treatment cases and methods (Note: TN in this table is mainly composed of NH 4+ -N and NO 3− -N; Comprehensive wastewater* refers to the mixed wastewater rich in fluoride and nitrate; Comprehensive wastewater** refers to the mixed wastewater of the three.).
However, the energy consumption increases if the influences mentioned above are improved. The process is generally treated using packed towers . To obtain a high removal rate, it is necessary to enlarge the size of the equipment or increase the number of equipment . So, it is not applicable to small PV wastewater treatment plants.
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.
