摘要：
试验采用SBR工艺的三种运行方式对高氨氮工业废水的处理进行了初步研究,并进一步对低溶解氧系统中的活性污泥进行了初始pH以及不同溶解氧浓度影响的探索。结果表明:对于去除氨氮,低溶解氧系统和传统的缺氧/好氧脱氮工艺具有相似的去除效率,但前者所需动力费用低;pH及溶解氧可作为系统运行的指示参数进行控制。

Abstract:
Three different SBR operating ways to remove the high strength ammonia - nitrogen industrial wastewater have been studied. Furthermore the effect of pH and DO on the low DO concentration activated sludge system has also been studied. The results show that as to the removal rate of ammonia, the low DO concentration activated sludge had the similar removal rate as the traditional system with the anoxic/aerobic alternative mode,but the operating cost of the former is decreased. So, pH and DO can be considered to be the controlling indicators for the operating of the system.
