| 摘 要： | 进水氨氮浓度不变，低DO下启动并运行了短程硝化试验，考察了反应器内的氨氮氧化和亚硝酸盐积累情况。试验结果表明反应器内氨氮几乎全部被氧化，污泥浓度从4500mg／L下降到870mg／L，此时亚硝酸盐的积累率为55％，说明只控制DO的浓度很难实现高的积累率，同时受到温度和污泥龄等的较大影响。

| Abstract: | A nitrification reactor was quickly started up and operated under low DO concentration with the steady influent NH 4 /L.The oxidation of ammonium and nitrite accumulation were investigated.The results showthat the ammonium were nearly oxidated and sludge chroma fall down from4500mg/L to870mg/L,at the same time,the nitrosation rate(NO 2 -N/NO 3 -N)is55%.The results showed that it was harder to realize high nitrosation rate,only by controlling low DO;temperature and sludge age were key elements. |
