摘　　要：以实际含氮有机废水的处理为研究对象,生化采用厌氧和好氧联合处理工艺,以控制好氧池中pH值的适当范围来研究系统的脱氮效果。通过小试和实际工程中对好氧池中pH范围的控制,废水脱氮效果明显。多项工程实践验证了生化处理时,通过调节pH到最佳范围来控制脱氮,从而高效处理含氮有机废水是切实可行的。该技术操作简便、投入少、运行效果稳定,具有推广价值。Dentrification is an effective technology to control nitrogen pollution from wastewater.The effect of pH on denitrification was analyzed.It was shown that pH exerted a large influence on the growth and metabolism of nitrifying bacteria.To a great degree,pH restricted the performance of nitrification reactor.Therefore,it is highly feasible to control denitrification by pH in a practical wastewater treatment project.
