Wastewater Classification
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.
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.
Frequently Asked Questions
What are the primary pollutants in saw blade cutting wastewater?
The main pollutants are "coolant" and saw blade cooling water. The coolant typically consists of resin acid (mainly rosin acid and hippocampal acid), unsaturated fatty acids, lignin, and their respective saponification and degradation products.
Why is water used during the grinding and trimming processes?
Water is primarily used as an auxiliary dust removal agent to minimize and control the large amount of dust pollutants generated during the surface processing of the boards.
Which processes consume the most water in glass deep processing?
Water consumption is heavily concentrated in the pretreatment stage, which specifically includes edge grinding, drilling cooling water, and washing water operations.
What substances are commonly found in glass pretreatment wastewater?
The wastewater contains a high volume of glass silica powder, along with smaller amounts of silica powder, corundum grit, cutting kerosene, cleaning agents, citric acid, additives, and various oils.
Why is glass processing wastewater difficult to biodegrade and treat?
Treatment is challenging because the wastewater is generated in large volumes, contains a highly concentrated amount of non-biodegradable glass silica powder, contains various oils and additives, and is generally acidic.
