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3.0mg·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。
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.
