| 摘 要： | 主要探讨了硝酸盐还原菌在缺氧条件下利用硝酸盐作为电子受体处理甲醇废水的可行性。结果表明，采用该法处理甲醇废水是可行的，最佳Ｎ／Ｃ比为１．４，ＣＯＤＣｒ去除率及ＮＯ＾－３－Ｎ利用率均可达到８０％以上。每消耗１ｍｇ的ＮＯ＾－３－Ｎ可以除２．９９２ｍｇ ＣＯＤＣｒ该值与进水浓度，Ｎ／Ｃ比及停留时间关系不大。

| Abstract: | Methanol wastewater was treated with denitrifying bacteria under anoxic condition and nitrate salt existing as electron acceptors, and the effect factors, such as N/C ratio, retention time etc. have been studied. The result showed that this method was feasible, and removal efficiency of CODCr and utilization ratio of NO3--N were more than 80% at N/C 1.4. 1mg NO3--N could remove CODCr of 2.992mg, which was irrelevant to concentration of methanol, ratio N/C and retention time. |
