Activated carbon is commonly used for the removal of organic contaminants from aqueous waste streams. It is frequently observed that carbon beds provide an excellent medium for microbial growth. This bioactivity is often regarded as a nuisance, although in many cases improvements in reactor performance are also noted. Some research attention has been devoted to intentionally operating carbon columns as combined bio/physico/chemical treatment system, mostly for municipal wastewater treatment. this proposal is based on the premise that activated carbon columns can be designed and operated for the treatment of contaminated groundwater supplies so that the processes of biodegradation and adsorption complement each other to provide treatment performance superior to that obtainable by either process alone. Experiments will be performed to evaluate the design and operational parameters affecting biological activated carbon systems, and to identify the mechanisms operative in such systems. This research is designed to lead to improved and less expensive treatment systems for hazardous waste site remediation.

活性碳通常用于去除有机污染物。 从含水的废流中。人们经常观察到，碳床 为微生物的生长提供了极好的介质。这种生物活性是 通常被认为是一种麻烦，尽管在许多情况下， 反应堆的性能也被记录下来。一些研究已经引起了关注 致力于故意操作组合后的碳柱 生物/物理/化学处理系统，主要用于城市污水处理 治疗。这项提议是基于这样一个前提，即活性碳 可以设计和操作塔来处理受污染的水 地下水的供应使得生物降解和 吸附相互补充以提供处理性能 比任何一种工艺单独获得的效果都要好。实验将是 执行以评估影响以下各项的设计和运行参数 生物活性碳系统，并确定其机理 在这样的系统中运行。这项研究旨在导致改进 以及较便宜的危险废物场地处理系统 补救措施。
