Application Area
Machining industry
Machine processing wastewater mainly comes from mechanical processing processes such as metal cutting, grinding, drilling, and milling. These wastewater typically contain multiple components, including the following categories:
1. Oil and coolant: cutting used in machining processes
Liquids, coolants, lubricating oils, and other substances typically exist in an emulsified state in wastewater and are difficult to separate.
2. Metal particles: Metal shavings, powders, etc. generated during the machining process
3. Surfactants: In order to improve the effectiveness of cutting fluid and coolant, surfactants are usually added to them. These surfactants may cause certain pollution to water bodies.
4. Wire drawing fluid is a metal processing fluid that has functions such as lubrication, cleaning, cooling, and rust prevention.
Ingredients: Various additives including lubricants, emulsifiers, rust inhibitors, cleaning agents, defoamers, fungicides, etc
5. The main pollutants in die-casting wastewater are suspended solids, heavy metals, organic matter, and oils, which also have high acidity, high COD, and BOD characteristics.
