An unsaturated polyester resin industry process waste resources

The invention discloses a process for recycling waste water from unsaturated polyester resin industry, which is characterized in that: usesful resources in the waste water are separated and recovered by an azeotropic distillation separation recovery technique; and the recovered ingredients are used to prepare a high-performance unsaturated polyester resin, so waste is changed into valuable materials and the product yield and performance of the unsaturated polyester resin are improved. The process solves the problem that resources in waste water cannot be separated and recycled with high efficiency and low energy consumption and burnt as waste in the current industry is solved, and the materials in the waste water are recovered and recycled to form the high-performance unsaturated polyester resin product; and thus, the environment pollution is reduced, and the development of circular economy is promoted. Therefore, the process has great economic and social benefit.
