Following the trend of energy reform, the development of photovoltaic is of great significance for achieving the goal of carbon peaking and the vision of carbon neutralization. In the production of photovoltaic cells, a large amount of hydrofluoric acid, hydrochloric acid, potassium/sodium hydroxide, flanneling additives, ammonia gas, etc. are used in the process of alkaline throwing and flanneling, plasma etching, dephosphorized silicon glass, etc. The corresponding wastewater mainly includes high fluoride wastewater, high nitrogen wastewater, etc. The standard of high pollution wastewater treatment is a prerequisite for the smooth development of the industry.
