The Influence of C,N on Anaerobic Ammonium Oxidation and Denitrification Coupling

为解决实际废水中有机物对厌氧氨氧化的抑制作用,以硝态氮为直接电子受体成功启动厌氧氨氧化与反硝化耦合装置,并在回流比优化工艺的基础上,通过调节碳氮、硝态氮与氨氮的比,优化耦合系统的脱氮除碳效率。结果表明,C/N、NO_(3)^(-)-N与NH_(4)^(+)-N的比为1.5时,耦合系统表现出较好的活性,硝态氮、氨氮和COD去除率分别99.2%、63.5%、95.8%和95.8%、85.8%、94.5%,达到较好耦合脱氮效果。为厌氧氨氧化的广泛应用及推广提供参考和技术支持。

In order to solve the inhibitory effect of organic in wastewater on anaerobic ammonia oxidation,the coupling and denitrification direct electron acceptor start-up of anaerobic ammonia oxidation device to nitrate nitrogen,and reflux ratio in the basis of the optimization of process,through the adjustment of carbon and nitrogen,nitrate nitrogen and ammonia nitrogen removal ratio,optimization of coupled system the removal efficiency of carbon.The results show that the ratio of carbon to nitrogen,nitrate nitrogen and ammonia nitrogen ratio is 1.5,the coupling system showed high activity,nitrate nitrogen,ammonia nitrogen and COD removal rate were 99.2%,63.5%,95.8%and 95.8%,85.8%,94.5%,achieve better coupling effect of nitrogen.To provide reference and technical support for the extensive application and popularization of anammox.
