Biotransformation of Selected Pharmaceuticals and Personal Care Products (PPCPs) in Biofilms

这个项目将调查生物膜工艺对药品和个人护理产品(PPCP)的去除，特别是那些用于废水回用的工艺，例如生物过滤、河岸过滤和土壤含水层处理。这项研究将检验这样一种假设，即生物过滤是从通过土壤通道和地下水回灌进行填海的废水流中去除选定的PPCP的有效处理方案。这将通过调查各种PPCP在用于模拟河岸过滤的小柱子中的转化和去除来实现。这些化合物可能会对生态产生影响，即使在经过处理的污水流出物中的浓度水平也是如此，这项工作的结果可能会提高我们对它们在地下水回灌和银行过滤以及在生物膜反应器中直接处理的情况下的命运的理解。鉴于PPCPs的使用日益增多，并在全国各地的许多河流中检测到PPCPs，这项提议是及时的，其结果可能会对公共卫生产生重要影响。

0606880BouwerThis project will investigate the removal of pharmaceuticals and personal care products (PPCPs) by biofilm processes, particularly those used in wastewater reuse, e.g., biological filtration, riverbank filtration, and soil aquifer treatment. This research will test the hypothesis that biofiltration is an effective treatment option for removing selected PPCPs from wastewater streams undergoing reclamation through soil passage and ground water recharge. This will be accomplished by investigating the transformation and removal of a variety of PPCPs in small columns intended to simulate riverbank filtration. These compounds can have ecological impacts, even at the concentration levels found in treated sewage effluents, and the results of this work could improve our understanding of their fate under scenarios of groundwater recharge and bank filtration, as well as direct treatment in biofilm reactors. Given the increasing use of PPCPs and their detection in many streams across the country, the proposal is timely and the results could have important public health consequences.
