Wastewater classification
1、Saw blade cutting wastewater (sawmill wastewater)
The main polluting components of glass processing wastewater are "coolant" and saw blade cooling water. Usually, the main components of the coolant are resin acid and its saponification products, unsaturated fatty acids and their saponification products, lignin and its degradation products. Resin acids are mainly rosin acid and hippuric acid and so on.
2、grinding wastewater and trimming machine wastewater
After processing the raw materials, the surface of the board is usually required to carry out further processing, there will be a lot of dust pollutants in the process. In order to reduce pollution, water is usually used as an auxiliary dust remover.
The water consumption in the glass further processing industry is mainly in the pre-treatment process, including water for edge grinding, cooling water for drilling and water for washing. The wastewater generated from the pre-treatment process contains a large amount of glass silica powder as well as a small amount of silica powder, diamond grit, cutting paraffin, washing agent and citric acid. Therefore, the wastewater is characterised by large volume, high concentration of glass powder, difficult biochemical degradation, etc. In addition, there are some additives and oils in the water, and the wastewater is generally acidic.
