Wastewater classification
1. Saw blade cutting wastewater (sawing machine wastewater)
The main pollutants of glass processing wastewater are "coolant" and saw blade cooling water. Generally, the main components of coolant are resin acid and its saponification products, unsaturated fatty acids and their saponification products, lignin and its degradation products, etc. Resin acid is mainly rosin acid and hippocampal acid, etc.
2. Grinding wastewater and trimming machine wastewater
After the raw materials are processed, the surface of the board usually needs to be further processed, and there will be a lot of dust pollutants during the processing. In order to reduce pollution, water is usually used as an auxiliary dust removal agent.
The water consumption of the 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, corundum grit, cutting kerosene, cleaning agent and citric acid. Therefore, the wastewater volume is large, the concentration of glass powder is high, and it is difficult to biodegrade. In addition, there are some additives and oils in the water, and the wastewater is generally acidic.
