Purification method and purification system for airborne molecular contaminants

Abstract

Provided are a purification method and a purification system (1) for AMC. The method comprises steps of: mixing AMC to be treated with a first water mist to obtain a gas-liquid mixture; subjecting the gas-liquid mixture to contact photocatalysts on a porous substrate under radiation into a first treated mixture; washing the first treated mixture and the porous substrate with a second water mist to obtain a water washed solution; and discharging a purified gas and the water washed solution. The molecular weight of the first treated mixture is lower than that of the AMC to be treated, and the AMC content in the purified gas is lower than that of the AMC to be treated. The technical means can improve the purification rate of AMC and extend the lifespan of the photocatalysts, thereby improving overall purification performance.
