The invention discloses a method for absorbing and coupling photocatalytic purification of isopropanol waste gas and water. The photocatalyst is added to the liquid, and the absorption coupled photocatalytic reaction is carried out under the conditions of illumination and stirring, the exhaust gas after the reaction is discharged up to the standard, and the isopropanol and the absorption liquid are recovered by the spray liquid; the isopropanol waste gas water absorption coupling photocatalytic purification proposed by the present invention The process can combine water absorption and photocatalysis into a whole, with small footprint, simple equipment, easy operation, mild reaction conditions, and can be widely used in the treatment of isopropanol waste gas in various industries. The purification rate of isopropanol waste gas reaches 97.1 %, and the degradation rate reaches 90.6%. |
