采用快速小型柱试验研究了预加载背景有机物（BOM）的颗粒活性炭床对间歇施用农药的去除效率。BOM预载降低了农药的去除效率。去除效率是BOM吸附量的函数，但与农药的进水浓度无关。采用理想吸附溶液理论和颗粒内表面扩散线性驱动力表达式的建模方法充分模拟了这些现象。包括30个参考文献、表格和图表。

The removal efficiency of intermittently applied pesticides by a granular activated carbon bed preloaded with background organic matter (BOM) was examined using the rapid small-scale column test. Preloading with BOM decreased the removal efficiency of the pesticides. The removal efficiency was a function of the amount of BOM adsorbed, but was unrelated to the influent concentration of the pesticide. A modeling approach employing the ideal adsorbed solution theory and a linear driving-force expression for intraparticle surface diffusion adequately simulated these phenomena.
