Description

technical field [0001] The invention belongs to the technical field of wastewater treatment equipment, and in particular relates to an aluminum alloy electrophoretic coating wastewater treatment device. Background technique [0002] At present, there are various treatment industries such as spraying, oxidation and electrophoresis for the surface treatment of aluminum alloy profiles. Among them, electrophoretic coating is a special coating film formation method developed in the past 30 years. Its main component is water-soluble acrylic resin, which has the characteristics of water solubility, non-toxicity, and easy automatic control. After coating the surface of the aluminum profile, it can increase the outdoor color retention and weather resistance of the aluminum profile. With the extensive application of electrophoretic coating technology, the wastewater brought by its production has increasingly become the focus of attention of various enterprises.

Problems solved by technology

[0004] According to the development needs of the aluminum profile industry, the national environmental protection requirements are constantly improving. The traditional treatment method is to directly discharge the wastewater containing electrophoretic coating to the factory collection pool for centralized treatment. However, often because this type of wastewater contains high concentrations of organic matter, many factories have It is difficult to meet the discharge standard in one treatment, which has brought significant production pressure to the environmental protection work of the enterprise
