SBR method is the short for intermittent sequencing batch freatment that is an ideal techmology to order a certain amount of intermittent operation of the activated sludge treatment process. SBR which is currently an in-depth study of the biological wastewater treatment technology is a simple process

the effect of stability

small footprint

and strong resistance to shock load and has good advantages of nitrogen and phosphorus removal capacity. This study first analyzes and discusses substrate degradation process of SBR method

compares among several different SBR methods

and then derives microbial growth and substrate degradation kinetics relationship with a view to promoting the progress of the work in this area.
