药物活性化合物 (PhACs)是当前全球关注的热点污染物，能穿过包气带进入地下水，但目前有关PhACs在包气带中的迁移转化和污染修复研究极其匮乏。本项目在前期研究的基础上，选取垃圾填埋场为研究区域，以包气带为载体，系统研究包气带中典型PhACs的污染特征，探讨典型PhACs在包气带中迁移转化规律，建立PhACs在包气带中的运移模型，预测其对地下水的影响；利用产电菌结合可渗透反应栅（Electricigen-Permeable Reactive Barrier, EG-PRB）修复包气带中PhACs的污染。该项目的研究成果对进一步掌握我国包气带中典型PhACs的污染现状、揭示包气带中PhACs的迁移转化规律，为包气带中PhACs对地下水的影响提供基础数据，并为包气带和地下水中PhACs的污染防治提供理论依据和技术支撑。

Pharmaceutically active compounds (PhACs) is one kind of hot pollutants on a global scale, the PhACs can enter groundwater by leaching from vadose zone, but the investigation on migration, transformation and pollution remediation in vadose zone is insufficient. Based on the previous studies, vadose zone as the carrier and refuse landfill as the survey region in the present study, the typical PhACs pollution characteristics, rule of migration and transformation, and migration model in vadose zone were researched systematically, the impact on groundwater was predicted. The electricigen combined the permeable reactive barrier technology（Electricigen-Permeable Reactive Barrier, EG-PRB）was used for vadose zone PhACs pollution remediation. The project is very important to further know the contamination status, rule of migration and transformation of PhACs in vadose zone, and providing basic data for impact of vadose zone PhACs on groundwater, and providing theory basis and the technical support for prevention and control of PhACs pollution in vadose zone and groundwater.
