Six 60-L benthic microbial electrochemical systems (BMESs) were built for the bioremediation of river sediment. Carbon mesh anodes with honeycomb-structure supports were compared with horizontal anodes, and the system was tested using different cover depths and anode densities. The pollutant removal, electricity generation, and electrochemistry of the six BMES with different anodes was examined using the Ashi River (Harbin, China) as a case study. Total organic carbon and total nitrogen removal from sediments in BMES with Honeycomb-structure anodes were 20-30% and 20-33% higher for the other reactors. The maximum power densities of 43.2 mW m was obtained in BMES. The maximum power densities in BMES with honeycomb-structure anodes were 10-40% higher than that of BMESs with horizontal anode reactors.
构建了六个60升的底栖微生物电化学系统（BMES）用于河流沉积物的生物修复。将具有蜂窝结构支撑的碳网阳极与水平阳极进行了比较，并使用不同的覆盖深度和阳极密度对该系统进行了测试。以中国哈尔滨的阿什河为例，研究了六个具有不同阳极的BMES的污染物去除、发电和电化学情况。与其他反应器相比，具有蜂窝结构阳极的BMES中沉积物的总有机碳和总氮去除率分别高出20%-30%和20%-33%。BMES获得的最大功率密度为43.2毫瓦/平方米。具有蜂窝结构阳极的BMES的最大功率密度比水平阳极反应器的BMES高出10%-40%。
