In order to improve the efficiency of biological nitrogen removal, the experiment used the luffa cylindrical sponge carrier sequencing batch biofilm reactor to treat domestic sewage, and it studied the temperature on the removal effect of TN in the sewage in the reactor and the changes of various types of nitrogen. The results showed that the TN treatment rate of the luffa cylindrical sponge carrier SBBR reached the peak at 30 °C, the removal rate was 82.25%, indicating that the luffa cylindrical sponge carrier SBBR is very suitable for the removal of nitrogen from domestic sewage.
