- Abstract:
- To investigate the application prospect of membrane aerated biofilm reactor (MABR) in wastewater treatment, and explore the rule of oxygen mass transfer and nitrogen removal in the reactor, a single stage MABR pure biofilm pilot plant was built in a wastewater treatment plant in Kunshan. The pollutants removal performance of MABR was explored under different load conditions, and the oxygen transfer efficiency in wastewater was analyzed. MABR greatly reduced the energy consumption of aeration while ensuring oxygen transfer. Obvious simultaneous nitrification and denitrification took place in the process of nitrogen removal in the MABR, and the higher concentration of pollutant was conducive to efficient utilization of oxygen. The 16S rDNA sequencing showed that the MABR biofilm had diverse microbial species, and aerobic microbes were the dominant.
