摘　　要：通过SBR短程硝化反硝化同步脱氮除磷工艺处理模拟啤酒生产综合废水,为达到稳定的COD、NH4+-N和TP的去除及NO2--N的积累,对该工艺的影响因素进行了研究。结果表明,工艺的稳定运行是由进水COD、pH、DO、温度和MLSS等因素共同作用的结果,其中控制较低的DO的质量浓度(<0.5 mg.L-1)是实现NO2--N积累的关键因素之一;过低或过高的进水pH、COD均会影响该工艺的正常运行。温度及MLSS含量会影响氨氧化过程与反硝化过程的反应速率,但不是系统稳定运行的决定因素。当DO的质量浓度为0.3～0.5 mg.L-1、进水COD低于1 100 mg.L-1、pH为7.2～8.4,在12～25℃可获得稳定的NO2--N积累。Shortcut nitrification-denitrification simultaneous nitrogen and phosphorus removal applying in SBR to treat the brewery wastewater,In order to achieve a stable removal of COD,NH4＋-N,TP and accumulation of NO2——N,we studied the factors of this process.The results show： the factors include COD concentration,pH,DO,temperature,and MLSS result of the stable operation of the process,control the low DO（0.5 mg·L-1） is one of the key factors to achieve the NO2——N accumulated.The pH and COD concentration which was too low or too high could affect the normal operation of the process.MLSS and temperature will affect the reaction rate of the ammonium oxidation process and denitrification process,but not the determining factor.When the DO is 0.3～0.5 mg·L-1,influent COD concentration below 1 100 mg·L-1,pH of 7.2～8.4,temperature in 12～25 ℃,the NO2——N accumulation stable.
