摘　　要：通过将SBR工艺和PACT工艺分别用于处理含氮废水。实验结果表明,在最佳工艺条件下(如温度为17℃、pH在6.8～7.5之间,进水COD质量浓度值为1000～1600mg/L左右),PACT工艺的COD去除率较高,平均高出SBR工艺约10%左右,且PACT工艺的工作稳定性较强,对污染物浓度的变化有较强的缓冲能力。相同水力停留时间内,PACT工艺具有更高的硝化能力。In the paper, SBR process and PACT process were used to treat the nitrogenous wastewater separately. The experimental result indicated that, in the same experimental conditions （for example, with temperature 17℃, the pH between 6.8 and 75 and the entering water＇s COD mass concentration value basically equal）, PACT process to COD removal rate was very high, which was about 10 % higher than SBR process＇s, and PACT process was also superior to SBR process in stability of work capability and adaptation to changes of the contaminate concentration. With the same HRT, the nitrification ability of active sludge in PACT process was enhanced well compared with SBR process.
