一种耦合厌氧产酸、正渗透和微生物燃料电池的三元污水处理方法
摘要：
本发明公开了一种耦合厌氧产酸、正渗透和微生物燃料电池的三元污水处理方法，属于污水处理技术领域。本发明方法包括以下步骤：污水打入厌氧产酸区，与NaOH溶液混合后进入MFC，使富集的有机物转换为生物电，再回流至厌氧产酸区。一部分混合液透过MF膜组件形成出水，并进入化学沉淀池去除磷酸盐，然后经过活性炭吸附柱，另一部分混合液透过FO膜组件获得出水，然后进入RO系统处理获得高品质的再生水。本方法将FO技术和MFC技术进行全新的耦合，最终构建了耦合厌氧产酸、FO和MFC的三元组合工艺，在厌氧产酸和FO截留作用下实现污水到有机酸的转变和积累，提升了MFC的产电性能，并利用FO和RO分离实现再生水回用，最终同步实现污水的回用与产电。
摘要（英）：

A ternary combined anaerobic reactor coupling anaerobic acidogenesis, forward osmosis (FO), and a microbial fuel cell (MFC), mainly comprising an anaerobic acidogenesis means (3), a draw solution tank (15), an RO film processing means (17), an MFC means (22), a settling tank (10), and an adsorption means (12). The anaerobic acidogenesis means (3) comprises an MF film assembly (6) and an FO film assembly (13); the MF film assembly (6) is connected to the settling tank (10) by means of a pipeline; the settling tank (10) is connected to the adsorption means (12) by means of a pipeline; the FO film assembly (13) is connected to the draw solution tank (15) by means of a pipeline; the draw solution tank (15) is connected to the RO film processing means (17); the MFC means (22) is connected to the anaerobic acidogenesis means (3). Also provided is a sewage treatment method using the ternary combined anaerobic reactor coupling anaerobic acidogenesis, FO, and an MFC.
