The Combined Pretreatment and Evaporation Process Was Used to Treat High Concentration Mixed Acid Wastewater in Photovoltaic Industry
The combined pretreatment and evaporation process was used to treat photovoltaic wastewater with high concentration mixed acid.The results show that the combined process can achieve"zero discharge"of photovoltaic mixed acid wastewater treatment,high purity of crystalline salt,high degree of automation,good economy,and provide favorable conditions for the recycling of subsequent resources.
