The main pollution factors of photovoltaic wastewater: fluoride ion, COD and pH value. The fluoride ions in the wastewater are mainly from hydrofluoric acid used in the production process. The organic pollution components in the wastewater are mainly from isopropyl alcohol and acetone used in the fluting tank (discharge frequency is very small), and the pH pollution factors are mainly hydrofluoric acid, hydrochloric acid, nitric acid and sodium hydroxide used in the production. Photovoltaic wastewater water quality characteristics: the concentration of wastewater pollutants changes greatly; The discharge of wastewater is divided into periods; The acid-base property of wastewater are very strong, and the corrosion of wastewater to equipment is great. Due to the large content of sodium silicate in wastewater and the inhibitory effect of alcohol on bacteria, the biodegradability of wastewater is very poor.

☆The removal rate of pollutants is high, and the effluent is stable and up to standard.
☆The system runs stably and the operating cost is low.
☆The process produces less sludge and the sludge treatment cost is low.
☆The system has high degree of automation and less operation and maintenance.
☆Integrated mobile, fast and convenient transportation installation.
