Biological wastewater treatment using biofilm systems is an effective way to treat difficult wastewater, such as coke wastewater. The information about the structure and dynamics of this microbial community in biofilm, which are responsible for treatment, relevant context efficacy biochemical potential remove various pollutants. However, physico-chemical factors can influence significantly, causing performance disturbances. Therefore, we decided examine rotating biological contactor (RBC) during investigate possible shift caused by feeding medium change from synthetic real experiment performed with high-throughput next-generation sequencing (NGS) revealed that bacteria commonly present plant (WWTP) systems, nitrite oxidizing, Nitrospira or Nitrobacter, were absent below detection threshold, while Nitrosomonas, ammonia was detected a relatively small number especially after This research indicates could cause autotrophic into heterotrophic nitrification led Acinetobacter. Moreover, be also source possessing high pollutants removal but less known WWTP well potentially pathogenic microorganisms.
