摘要
为了提高市政污水处理工艺水平,选取A/O-MBR组合工艺及A/O工艺作为市政污水处理工艺,开展试验测试分析。本次试验选取HRT、回流比作为变量,探究不同变量条件下的A/O-MBBR和A/O系统除碳效果、硝化效果、脱氮效果变化状况。结果显示:A/O-MBBR组合工艺在不同HRT条件下的硝化及脱氮效果改善明显,在不同回流比条件下的除碳及硝化效果改善明显,100%回流比条件下的脱氮效果最佳。
In order to improve the level of municipal sewage treatment process, a/O-MBR combined process and a/O process are selected as municipal sewage treatment process for experimental test and analysis. In this experiment, HRT and reflux ratio were selected as variables to explore the changes of carbon removal effect,nitrification effect and nitrogen removal effect of a/o-mbbr and a/O system under different variables. The results showed that the nitrification and denitrification effects of a/o-mbbr combined process were significantly improved under different HRT conditions, the carbon removal and nitrification effects were significantly improved under different reflux ratio, and the denitrification effect was the best under 100% reflux ratio.
