| 摘 要： | 文章采用生物膜法进行对低碳氮比的污水模拟研究,通过调节反应池的各种条件如水力停留时间,进水的碳氮比等考察生物膜法对低碳高氮污水的脱氮能力。在本试验所考察的工况中,系统进水停留时间为15小时,原水C/N为5:1,低氧反应池与好氧反应池进水比为1:1的工况有较好的脱氮效果,改善了出水水质,对城市污水深度脱氮具有参考价值,有良好的应用前景。

| Abstract: | There is no effective,stable and energy saving method to removal of the nitrogen from the municipal sewage with the low carbon source-high nitrogen concentration,such as the munisipal secondary effluent.In this study,the biofilm process was applied to treat such kind of wastewater.The capability of denitrification for low carbon source-high nitrogen concentration wastewater by biofilm process was investigated by changing the reaction conditions such as HRT,C/N etc.In this study,under the conditions of the H... |
