Combined effects of electrical current and nonsteroidal antiinflammatory drugs (NSAIDs) on microbial community in a three-dimensional electrode biological aerated filter (3DE-BAF).

Three-dimensional electrode biological aerated filter (3DE-BAF) with particulate bioelectrode from lithium slag was used to simultaneously remove diclofenac and clofibric acid from the synthetic domestic sewage, and the combined effects of electrical current and nonsteroidal antiinflammatory drugs (NSAIDs) on microbial community was analyzed. The results indicated that (1) the average diclofenac and clofibric acid removal efficiency in the 3DE-BAF firstly increased, attained the peak of 79.40 ± 6.
