摘　　要：为了在处理城市污水中应用好氧曝气实时控制实现短程硝化,研究其机理及操作方式。在3个不同截面形状、不同体积的序批式反应器内,用实际生活污水进行了验证试验。结果表明:利用曝气时间实时控制,在每个周期内氨氧化菌(AOB)降解氨氮质量大于亚硝酸盐氧化菌(NOB)降解亚硝态氮质量;AOB的净增数量大于NOB净增数目。经长期曝气时间实时控制,亚硝化积累率将会逐渐升高。短程硝化启动后,亚硝态氮积累率可维持在80%以上。The kinetic mechanism and operation for partial nitrification using real-time aeration duration control was analyzed for municipal wastewater treatment.The validation experiment was conducted in 3 sequencing batch reactors with cross section shapes and various volumes using domestic wastewater as the influent.Analysis shows that more nitrogen is oxidized by ammonia oxidizing bacteria（AOB） than by nitrite oxidizing bacteria（NOB） with more growth of the AOB than the NOB in each cycle when using this method.The nitrite accumulation increases after long-term application of real-time aeration duration control.Partial nitrification to nitrite with nitrite accumulation ratios of over 80% was successfully achieved using real-time control in the three reactors.
