Description

technical field

[0001] The invention relates to the field of waste water treatment of wall imitation stone paint, in particular to a method for treating waste water of wall imitation stone paint. Background technique

[0002] In recent years, with the rapid development of the real estate industry, the amount of imitation stone paint on walls has gradually increased. Wall imitation stone paint is a kind of paint that resembles marble and granite. The paint has the characteristics of waterproof, fireproof, non-toxic, acid and alkali resistance, and strong oxidation resistance. It has been fully used in modern exterior wall decoration and gradually replaced Traditional stone such as marble and granite.

[0003] Wall imitation stone paint wastewater is wastewater with high organic matter and high suspended solids. The wastewater contains cellulose, plasticizers, thickeners, film-forming aids, emulsions and other raw materials. The wastewater will be discharged directly into the...
