Abstract :
A sequencing batch biofilm reactor (SBBR) treating domestic wastewater in low temperature (T<;10.0□) was studied. The results showed: the average removal rates for CODCr, NH4+-N, TN and turbidity were 93%, 98%, 71% and 97%, respectively. The operation mode of sequencing batch made a gradient of substrate with time as plug-flow and the biofilm distributed equally. High biomass concentration, long aeration time and bio-filtration could increase the removal efficiency of COD, NH4+-N and turbidity in low temperature. Simultaneous nitrification and denitrification in biofilm could enhance the removal of TN.TN.
