The oil fume adsorption experiment was conducted by sepiolite gain with particle size of 1.8mm to analyze adsorption capacity of oil fume, obtain breakthrough curve and propose the method of sepiolite regeneration. 用所制得的粒径为1.
The effects of concentration, flow and temperature to the adsorption performance for the VOCs on Calgon AC were investigated from the breakthrough time, adsorption capacity and shape of breakthrough curve. 从穿透曲线的形状、穿透时间和穿透吸附量等方面，考察初始浓度、流量和温度等因素对三种有机物在Calgon活性炭上动态吸附行为的影响。
The breakthrough curve (BTC) of prefential flow was asymmetirc, which was proved by the analysis on its average penetrating time and the extent of its spreading and lagging. 同时采用驻留力矩分析穿透曲线（BTC）的平均穿透时间以及蔓延扩散和拖尾程度，结果表明优先流的穿透曲线具有不对称性。
Under unsaturated condition, the duration of the transport process was obviously prolonged, peak value of the breakthrough curve raised, the preferential flow was not significant and the curve was gently. 在非饱和条件下，硝态氮运移过程的时间明显加长，穿透曲线的峰值增高，优先流不明显，穿透曲线平缓。
