| titleOfInvention | The treatment process of acid waste water in 2-ethyl-anthraquinone production process |
| abstract | The invention discloses the treatment process of acid waste water in a kind of 2-ethyl-anthraquinone production process, comprise (1) and the acid waste water obtained in 2-ethyl-anthraquinone production process and ammoniacal liquor are carried out neutralization reaction, the neutralization reaction obtaining liquid containing ammonium sulfate completes liquid and discharges reaction heat, reaction heat makes the water generation vaporization in reaction system, obtains evaporation condensed water and reclaim after condensation; (2) neutralization reaction is completed liquid and carry out vacuum filtration, remove filter residue, obtain thick ammonium sulfate liquor, adsorb the organic sulfonated bodies in thick ammonium sulfate liquor with atlapulgite, after filtration, obtain ammonium sulfate liquor; (3) ammonium sulfate liquor is carried out dehydration concentration, obtain the magma containing ammonia sulfate crystal and recycle-water, centrifugation and drying are carried out to magma, obtains ammonium sulfate product.Treatment process of the present invention can sulfuric acid in efficient recovery acid waste water, realize the cycling utilization of wastewater of acid waste water and the zero release of acid waste water. |
