摘要：
Nitrogen removal efficiency related to the dissolved oxygen (DO) concentration (DO 1-7 mg l-1), carbon/nitrogen ratio (COD/N 1-14), and the effect of airflow (0.4-2.9 l min-1) related to the granule size were investigated. The average chemical oxygen demand (COD) removal of =90 % was achieved at COD/N =11, but the satisfactory N values in effluent for discharge into the surface waters were almost achieved at COD/N 14. DO of 2 mg l(-1) is recommended for efficient removal of N and COD with mature granules. The size (diameter) of the granules decreases with increased airflow.
