China Glass Grinding and Polishing Wastewater Treatment Suppliers | Factory Solutions for Coolant Pollution
Features
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.
Deep Processing Wastewater Characteristics
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 main pollutants in glass 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.
Why is water used during the glass grinding and trimming process?
During the surface processing of the boards, a significant amount of dust pollutants is generated. Water is utilized as an auxiliary dust removal agent to minimize this air pollution.
Where is the most water consumed in the glass deep processing industry?
Water consumption is primarily concentrated in the pretreatment processes, which include edge grinding, drilling cooling water, and washing water operations.
What materials are found in glass pretreatment wastewater?
The wastewater contains a large volume of glass silica powder, along with smaller amounts of corundum grit, cutting kerosene, cleaning agents, citric acid, additives, and oils.
Why is glass processing wastewater difficult to treat?
It is difficult to treat because the wastewater volume is very large, the concentration of glass silica powder is extremely high, the pollutants are difficult to biodegrade, and the water contains various acidic additives and oils.
Is glass deep processing wastewater acidic or alkaline?
The wastewater is generally acidic due to the presence of citric acid, cleaning agents, and other acidic additives used during processing.
