Wastewater classification
1. Saw blade cutting 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 & trimming 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
Q: What are the main pollutants in saw blade cutting wastewater?
The main pollutants are "coolant" and saw blade cooling water. The coolant typically contains resin acid (such as rosin acid and hippocampal acid) and its saponification products, unsaturated fatty acids, and lignin degradation products.
Q: Why is water used during the glass grinding and trimming process?
Water is primarily used as an auxiliary dust removal agent to minimize and control the large amount of dust pollutants generated when processing the surface of the board.
Q: Where is the water mostly consumed in the glass deep processing industry?
Water consumption is mainly concentrated in the pretreatment process, which specifically includes edge grinding, drilling cooling water, and washing water.
Q: What components make glass pretreatment wastewater difficult to biodegrade?
The wastewater contains a large volume and high concentration of glass silica powder, along with corundum grit, cutting kerosene, cleaning agents, citric acid, and various additives and oils.
Q: What is the typical pH level of glass deep processing wastewater?
The wastewater generated is generally acidic due to the presence of citric acid, cleaning agents, and other acidic chemical additives used during the pretreatment process.
