活性炭吸附法是目前最为广泛使用的处理ＶＯＣｓ的方法之一，本实验用苯、甲苯、二甲苯作为ＶＯＣｓ的代表物，研究ＶＯＣｓ的浓度、物化性质及气流量对活性炭吸附的影响．实验结果表明，ＶＯＣｓ度与穿透时间的对数成线性关系；物化性质对透过点有影响，甲苯比苯更易透过；流量大的ＶＯＣｓ气流较快透过． Activated carbon adsorption is one of the most widely used methods for VOCs treatment. In this experiment, benzene, toluene and xylene were used as representative of VOCs to study the influence of VOCs concentration, physicochemical properties and gas flow on the adsorption of activated carbon. The experimental results show that the VOCs have a linear relationship with the logarithm of the breakthrough time. The physical and chemical properties have an influence on the transmission point, toluene is more permeable than benzene, and the flow of VOCs is faster.
