研究了活性碳缓冲预处理与生物滴滤相结合去除挥发性有机物(VOC)的能力。考察了商用活性碳对间二甲苯、丙酮和乙酸正丁酯(典型油漆溶剂)的吸附能力，包括在不同进气条件下对吸附化合物互换和混合物的响应。间二甲苯和乙酸正丁酯的吸附主要是不可逆的，是丙酮的3倍以上。在连续的吸附/解吸循环中，先前使用的活性碳影响了吸附和缓冲容量。结果用Dubinin-Radushkevich方程关联。在处理工业排放的全尺寸生物滴滤池中去除VOC证实了使用被动式活性碳预过滤器的好处。这些技术的结合提高了消除能力，并促进了生物过程的更有效的表现。VO..。
The capacity of activated carbon as a buffer pretreatment combined with biotrickling filtration for volatile organic compound (VOC) removal has been studied. The adsorption capacity of commercial activated carbons for m-xylene, acetone and n-butyl acetate (typical paint solvents) was evaluated, including the response to the interchanging of adsorbed compounds and to mixtures over fluctuating inlet conditions. The adsorption of m-xylene and n-butyl acetate was mainly irreversible and more than three times higher than for acetone. The prior use of activated carbon influenced adsorption and buffer capacities in consecutive adsorption/desorption cycles. The Dubinin–Radushkevich equation was used to correlate the results. VOC removal in a full-scale biotrickling filter treating industrial emissions confirmed the benefit of using a passive activated carbon prefilter. A combination of these technologies increased the elimination capacity and promoted a more efficient performance of the biological process. The VO...
