为了评估GAC吸附在特定处理目标方面的可行性，通常需要进行中试研究。本文的目的是讨论GAC试点研究设计和评估的重要考虑因素；具体来说，将讨论可能遇到的典型结果和问题。在评估中试和全尺寸GAC性能数据时，可以确定有关GAC柱中发生的去除机制的重要信息:当从天然水中去除微量有机化合物时，背景有机物（BOM）可以取代目标化合物，导致下流GAC柱顶部的容量降低；通过BOM预加载可以减少可接近的吸附点的数量，从而降低下游GAC柱的容量； GAC吸附器的EBCT可能太短，无法有效容纳目标化合物的整个传质区，从而导致高CUR；为了确定GAC过滤器中生物活性的有效性，需要进行足够长时间的试点研究；臭氧氧化可能会也可能不会增加有机碳的可生物降解部分。

Pilot studies are often necessary to evaluate the feasibility of GAC adsorption with regard to specific treatment goals. The objective of this paper is to discuss important considerations about the design and evaluation of GAC pilot studies; specifically, typical results and problems that might be encountered will be discussed. When evaluating pilot and full scale GAC performance data, important information about the removal mechanisms that take place in GAC columns can be determined: When removing trace organic compounds from natural waters, background organic matter (BOM) can displace the target compound leading to lower capacities in the top portion of a downflow GAC column; Preloading by BOM can reduce the number of accessible adsorption sites leading to lower capacities in the lower reaches of a downflow GAC column; The EBCT of a GAC adsorber can be too short to effectively contain the entire mass transfer zone of the target compound leading to high CURs; To determine the effectiveness of biological activity in GAC filters, pilot studies need to be run for a sufficiently long time; Ozonation may or may not increase the biodegradable fraction of organic carbon.
