| titleOfInvention | Method for recycling and innocent treatment of organic amine solvent |
| abstract | The invention discloses a method for the recycling and innocent treatment of an organic amine solvent and belongs to the technical field of environmental protection. The method comprises the following steps that: an organic amine waste liquid is filtered, is in countercurrent contact with an absorption solvent with high selectivity and low vaporization enthalpy in an extraction tower, and is extracted and rectified to form a solvent A and an active ingredient, namely organic amine; the waste liquid is converted into nitrogen-containing inorganic ions through high-temperature oxidation digestion treatment, and the chemical oxygen demand (COD) meets discharge requirements; and the pH value of the treated waste liquid is regulated to be neutral so as to serve as a chemical fertilizer. The method is easy to operate and low in cost, and can be used for recycling the active ingredient from the organic amine solvent waste liquid and performing innocent treatment on toxic ingredients. |
