Method and equipment for water resources treatment of propionic acid and butyric acid secondary mother liquor |
| abstract |
A pollution-free resource treatment method for propionic acid or butyric acid secondary mother liquor waste liquid, first separating light components (water-containing) and heavy components from propionic acid or butyric acid secondary mother liquor water; The components are cut again by vacuum distillation to separate most of the acidic water containing a small amount of light components from the light components; the acidic water containing a small amount of light components is sent to the factory sewage treatment system; decolorization, deodorization and neutralization are adopted. The light and heavy components are treated with two methods to obtain an intermediate with light color and a pH value that is almost neutral; the intermediate is aminated or boronized to obtain a water-based industrial oil raw material for metal processing. alternatives. |
