| 摘 要： | 研究了在活性污泥工艺中用投加硝化菌的方法提高硝化效率的特性，试验用富氮废水生成硝化污泥，并将其剩余硝化污泥投加于处理初沉市政污水的活性污泥工艺试验装置，研究结果表明，投加硝化菌能降低常规活性污泥工艺硝化的泥龄要求、改善硝化效果以及减少为低温稳定运行而增加的硝化反应器容积。

| Abstract: | The influence of nitrification efficiency with adding nitrifying bacteria to the activated sludge process was investigation.During experiment nitrifying sludge was produced with rich- nitrogen wastewater and excess sludge was added to the activated-sludge reactor,which treat pre-precipitated municipal wastewater.The experimental results showed that adding nitrifying bacteria may decreased requirements at sludge ages,improved nitrifying efficiency and reduced reactor volume for a stable operation in low temperature. |
