摘要
本文就活性污泥法废水脱氮过程中C/N值对N_2O气体形成及废水处理脱氮效果的影响进行探讨。试验结果表明,C/N≥4.5时,脱氮过程中没有N_2O气体释放大气中,总脱氮率≥92%;而当C/N≤3.0时,由NH_3—N转化为N_2O—N的百分比随C/N值下降而升高。
This paper studying the influence of C/N in an activated sludge on the release of nitrous oxide and the nitrogen removal.When C/N≥4.5,NH_3-N was not transformed to N_2O-gas and total nitrogen removal rate was ≥92%.When C/N≤3.0,the percentage of NH_3-N to N_2O-N increased with the decrement of C/N and the rate of nitrogen removal decreased.
