Process for treating waste water from propylene oxidation plants |
摘要 |
Processes for treating the waste water, particularly waste water containing certain unsaturated compounds, from acrolein and acrylic acid production plants to reduce the chemical oxygen demand (COD), which processes comprise polymerizing the unsaturated compounds, desirably with peroxygen compounds; neutralizing the waste water with a reagent forming polyvalent metal ions to provide salts of the polymerized compounds; and separating the salts so formed.
