The treatment of wastewater from glass factories mainly adopts a combined process of “pretreatment + main treatment + advanced treatment + reuse” to achieve compliant discharge or resource reuse, as detailed below:<\/p>\n\n\n\n
1. Pretreatment<\/p>\n\n\n\n
1.1 Bar screen\/screen: Removes large particulate impurities<\/p>\n\n\n\n
1.2 Equalization tank: Balances water quality and quantity<\/p>\n\n\n\n
1.3 Sedimentation tank: Initially removes suspended solids<\/p>\n\n\n\n
1.4 Oil separator (if oily wastewater): Separates oily substances<\/p>\n\n\n\n
2. Main treatment<\/p>\n\n\n\n
2.1 Coagulation and sedimentation: Adds polyaluminum chloride (PAC) and polyacrylamide (PAM) to remove suspended solids and colloids<\/p>\n\n\n\n
2.2 Chemical precipitation:<\/p>\n\n\n\n
2.3 Defluoridation: Adds lime milk to generate calcium fluoride (CaF\u2082) precipitate<\/p>\n\n\n\n
2.4 Heavy metal removal: Adjusts pH to precipitate heavy metal hydroxides, or adds chelating agents<\/p>\n\n\n\n
2.5 Air flotation (suitable for oily and fine suspended solids): Improves removal efficiency<\/p>\n\n\n\n
3. Advanced treatment<\/p>\n\n\n\n
3.1 Biological treatment: If organic matter is high (COD > 500 mg\/L), hydrolysis acidification + 3.1 Contact oxidation or MBR membrane bioreactor<\/p>\n\n\n\n
3.2 Advanced oxidation (e.g., ozone, Fenton): Degrading recalcitrant organic matter<\/p>\n\n\n\n
3.3 Membrane separation: Ultrafiltration (UF) + Reverse osmosis (RO) ensures effluent reuse standards<\/p>\n\n\n\n
4. Reuse and resource recovery<\/p>\n\n\n\n
4.1 Effluent can be used for raw material cleaning, cooling water replenishment, etc., with a reuse rate of 80%\u201390%.<\/p>\n\n\n\n
4.2 After dewatering, sludge is disposed of in a safe landfill or utilized for resource recovery, depending on its composition.<\/p>","protected":false},"excerpt":{"rendered":"
