Description

technical field

[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a paint wastewater treatment system. Background technique

[0002] No matter what kind of spraying method is used in the painting process, it is impossible to make the paint mist completely adhere to the surface of the coated workpiece, and a part of overspray paint mist will always be generated. Reducing the discharge of organic solvents, protecting the environment, saving energy and resources, reducing costs, and ensuring the quality of spraying are the directions that the painting industry is constantly pursuing, and efforts to improve the recovery rate of overspray paint are currently a bottleneck in the painting industry. Increased overspray recovery rate means reduced paint consumption costs, improved working conditions for operators, and benefits for fire protection and labor safety. At the same time, it reduces the cleaning frequency of the paint...
