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

0606880 Bouwer该项目将研究通过生物膜工艺去除药物和个人护理产品（PPCP），特别是用于废水再利用的那些，例如，生物过滤、河岸过滤和土壤含水层处理。本研究将测试的假设，生物过滤是一种有效的处理方案，通过土壤通道和地下水回灌去除选定的PPCPs进行复垦的废水流。这将通过研究旨在模拟河岸过滤的小柱子中各种PPCP的转化和去除来实现。这些化合物可以有生态影响，即使在处理后的污水中发现的浓度水平，这项工作的结果可以提高我们的理解他们的命运下的地下水补给和银行过滤的情况下，以及在生物膜反应器中的直接处理。鉴于PPCPs的使用越来越多，而且在全国许多溪流中发现了PPCPs，该提案是及时的，其结果可能会产生重要的公共卫生后果。

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.
