Description

technical field

[0001] The invention relates to the treatment technology of industrial wastewater, in particular to the technical field of coating wastewater treatment. Background technique

[0002] Automobile (or other mechanical equipment) painting is the main measure to protect and decorate automobiles (or other mechanical equipment), and it is one of the very important manufacturing processes. The water pollutants discharged during the coating process, such as resins, surfactants, phosphates, and high-concentration organic matter, can cause serious pollution. Due to the complex composition of coating wastewater and irregular discharge, the water quality changes greatly, the treatment equipment has a long process, many types, covers a large area, time-consuming and labor-intensive operation, and high operating costs. Water cannot be reused for production. Contents of the invention

[0003] The purpose of the present invention is to invent a complete treatment process ...
