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.
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.
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.
If low-cost environmentally friendly catalysts can be found, the application of photocatalysis technology in PV wastewater could be promising. In short, of all the above methods, biological treatment is the most economically feasible and the primary choice for treating ammonia-rich and nitrate-rich wastewater.
