| 摘 要： | 试验采用人工配制污水,以醋酸钠为COD来源,以硝酸钠为硝氮来源,对SBR颗粒污泥反硝化系统中C/N对反硝化作用的影响、反硝化过程中pH和ORP的变化规律进行了研究,得到适宜的C/N约为5,并验证了通过测定pH和ORP曲线拐点可准确判断反硝化反应终点。

| Abstract: | Synthetic wastewater was used,and COD was from NaAC,NO3-N was from NaNO3.In SBR granular sludge system,the influence on nitrification under different the ratio of C and N and the rule of pH and ORP curve were studied in this paper.And the ratio of C and N which is suitable approximately is 5 was obtained,and end point of nitration judged by the pH value and the ORP breaking point was confirmed. |

| Keywords: | SBR nitration granular sludge the ratio of C and N pH ORP |
