Glass ink manufacturers in the production of water-based glass ink and the use of the process, due to the cleaning of the equipment, will produce a certain amount of waste water. How to deal with water-based glass ink wastewater? chemical oxidation-coagulation process The composition of wastewater mainly includes water-based glass ink, starch and surfactant. Through the use of oxidation decolorant KMnO4, H2O2, NaClO, activated carbon selectivity test; Through the flocculant: Y-13, FSH7, FCH3, FO4248, AN910SH screening test and dosage and pH adjustment test. The results showed that under the best experimental conditions of adding the best oxidant NaClO15g g/L, the best coagulant FCH 30.2g/L and pH adjustment of 8.5, the CODcr removal rate reached 94% and the chroma removal rate reached 100.
