Research status of typical wastewater treatment technology for photovoltaic cell production process

Popis výsledku v původním jazyce

The photovoltaic (PV) cell industry is undergoing significant growth, driven by the expanding application of PV power generation technology. However, this expansion has increased wastewater production, posing substantial environmental challenges. The texturing process in PV cell manufacturing uses hydrofluoric acid, nitric acid, isopropanol, and other chemicals, generating wastewater with high concentrations of fluoride ions, nitrate ions, and Chemical Oxygen Demand (COD). Furthermore, wastewater from silane towers contains elevated levels of ammonia nitrogen. If not effectively treated, these pollutants can cause severe environmental damage. This review comprehensively examines the treatment technologies for fluorine-rich, ammonia-rich, and nitrate-rich PV wastewater, revealing the advantages, disadvantages, and comparisons of the various technologies, as well as possible solutions. The main treatment process for fluorine-rich PV wastewater is summarized as chemical precipitation, while biological treatment is primarily used for ammonia-rich and nitrate-rich PV wastewater. Practical treatment cases studies are provided to support these findings. Finally, the review presents an outlook on future research directions, addressing the challenges encountered in current practices.
