VOCs absorbent and method for absorbing and treating VOCs waste gas by using VOCs absorbent

The invention discloses a VOCs absorbent and a method for absorbing and treating VOCs waste gas by using the VOCs absorbent, and belongs to the field of purification and emission of the VOCs waste gas, the absorbent is a compound formed by lubricating oil fractions and an organic active agent, the organic active agent has aromatic ring and branched chain structures, the VOCs absorbent is used as an absorbent in a supergravity absorption technology, and the VOCs waste gas can be absorbed and treated by using the VOCs absorbent. After supergravity absorption, combustion treatment is carried out; and finally, after purification treatment, up-to-standard emission or ultra-clean emission is carried out. According to the absorbent disclosed by the invention, the lubricating oil fraction and the organic active agent with aromatic ring and branched chain structures are selected and interact with each other, so that the polarity of a molecular structure is improved, the intimacy between the main absorbent and the chem
