摘要
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(如温度为17℃、pH值在6.8~7.5之间,进水COD质量浓度值为1000~1600 mg/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 this paper, SBR process and PACT process were used to treat the nitrogenous wastewater separately. The experimental results indicate that, in the same experimental condition (for example: the temperature is 17℃, the pH value is between 6.8 and 7.5 and the influent concentration of COD is 1 000-1 600 mg/L), COD removal rate of PACT process is very high, which is about 10G higher than SBR process's. PACT process is also superior to SBR process in stability of work capability and adaptation to changes of the contaminate concentration. During the same HRT, the nitrification ability of active sludge in PACT process was enhanced well than SBR process.
