Glass production enterprises are big water consumers. The water consumption of glass deep processing industry is mainly in the pretreatment process, including edge grinding, drilling cooling water and washing water. The wastewater generated in the pretreatment process contains a large amount of glass silica powder and a small amount of silica powder, diamond grit, cutting kerosene, cleaning agent and citric acid, oil, SS, fluorine and heavy metals. If the wastewater is not treated and discharged directly, it will cause serious harm to the natural environment and humans.
