| 摘 要： | 本文以SBR为主体处理过程,对分别以葡萄糖、甲醇、乙酸为碳源时反硝化脱氮过程进行研究,结果表明,以乙酸为碳源的SBR系统在水力停留时间为2.5 d时,NO3-N脱氮速率和去除率可达16.67 mg NO3-N/(L.h)和94.7%,可实现高浓度硝酸根废水处理出水硝酸氮浓度小于50 mg/L。

| Abstract: | In the article we make an exhaustive study on the process of the SBR craft which use the different carbon source including grape sugar,methanol,acetic acid to take off nitrogenous.The result showed that when the water power stops over time was 2.5 d,the SBR craft using acetic acid has nitrogen removal rate 16.67 mg NO3-N/(L.h) and nitrogen removal percentage 94.7%,promising to get a water which nitric acid nitrogen content low in 50 mg/L. |
