通过二级A／O工艺在制革废水脱氮改造处理工程的实践，探索了脱氮工程的运行控制条件，并提出了制革废水脱氮工程去碳和脱氮分级处理的建议。去碳和脱氮分级处理具有投资省、运行费用低、工况易控等优点，其中，二级脱氮建议采用短程生物硝化一反硝化工艺，该工艺具有耐负荷冲击能力强、脱氮效率高、运行稳定的特点，值得推广。
通過二級A／O工藝在製革廢水脫氮改造處理工程的實踐，探索瞭脫氮工程的運行控製條件，併提齣瞭製革廢水脫氮工程去碳和脫氮分級處理的建議。去碳和脫氮分級處理具有投資省、運行費用低、工況易控等優點，其中，二級脫氮建議採用短程生物硝化一反硝化工藝，該工藝具有耐負荷遲擊能力彊、脫氮效率高、運行穩定的特點，值得推廣。

On the basis of practice, this paper explores the control conditions of denitrification, and puts forward proposals for stage treatment of carbon removal and denitrification in tannery waste water denitrification. Stage treatment of carbon removal and denitrification has virtues of low investment, low operation cost and easy control etc. The author recommends short-cut nitrifieation-denitrification in two-stage denitrification. It is good for popularization because of strong bearing capability against impact load, high efficiency of denitrification and stable operation.
