摘　　要：变电站高氨氮含量废水环境危害大,是水处理领域亟待解决的问题。在缺氧-好氧管式膜膜生物反应器建立短程硝化反硝化过程处理高氨氮含量废水,系统考察了膜生物反应器中聚氨酯填料投加的强化脱氮效果及对膜污染的控制。结果表明:填料可以提高好氧池生物量,改善硝化过程,并通过填料内部的厌氧微环境实现同步硝化反硝化。在填料填充10%、回流比200%时,氨氮和总氮去除率达到92%和68%,同步硝化反硝化对总氮去除贡献约10%,膜清洗间隔可延长至11 d。High ammonia wastewater in the substation is harmful to the environment,which is an urgent issue to be addressed in water treatment.In this paper,a shortcut biological nitrogen removal was established in an anoxic-aerobic tubular membrane bioreactor for the treatment of high ammonia wastewater.The effect of polyurethane fillers in membrane bioreactor on enhanced nitrogen removal and membrane fouling was comprehensively investigated.The results indicated that not only did the fillers increase the biomass in the aerobic tank and improve the nitrification,but also realized simultaneous nitrification and denitrification due to the anaerobic microenvironment inside the fillers.The removal of ammonia nitrogen and total nitrogen was 92%and 68%when the filler volume was 10%of the reactor volume and the reflux ratio was 200%.Simultaneous nitrification and denitrification accounted for 10%of the total nitrogen removal,and the single filtration period of the membrane extended to 11 days.
