Application of MABR process in wastewater treatment and analysis of its influencing factors
The mutual combination of permeable membrane aeration for oxygen supply and biofilm process has formed an innovative wastewater treatment technology,i.e.,membrane aeration biofilm reactor(MABR),which has received extensive attention and research in recent years.Based on the introduction of membrane materials,membrane components and mass transfer mechanism of MABR,we focused on the review of the influence of oxygen transfer rate,hydraulic retention time(HRT),carbon/nitrogen ratio(C/N),biofilm thickness,and pH on the process system of MABR in the process of practical application.Finally,MABR as an energy-saving and carbon-reducing water treatment process has become a break-through for improving quality and reducing consumption of traditional sewage plants in China.
