| 摘 要： | 在好氧条件下,向反应器中装填悬浮填料进行脱氮试验,考察生物膜法对氨氮和总氮的去除效果.结果表明：DO为3.0 mg.L-1时,氨氮平均去除率达到89.52％、总氮平均去除率达到29.46％.在好氧条件下,生物膜脱氮效果明显,硝酸盐氮的积累使反硝化过程成为脱氮的制约因素之一.

| Abstract: | This experiment focused on the nitrogen removal process by adding suspended carriers under aerobic condition.The results indicated that ammonia nitrogen average removal rate was 89.52％ and total nitrogen average removal rate was 29.46％ when DO was 3.0 mg · L-1.Under aerobic condition,nitrogen removal of biofilm worked well and denitrification became one of the limiting factors of nitrogen removal due to accumulation of nitrate. |
