摘　　要：以化纤厂废水处理曝气池的活性污泥为接种污泥 ,采用生物法处理硝酸碱吸收后的含NOx 尾气。初步研究表明 :静态、动态培养驯化挂膜后 ,可见到短杆菌属的脱氮菌 ,在进气浓度、循环液pH值、液气比等一定的条件下 ,可获得较高的脱氮效率。生物法是净化含NOxA biological method is used to treat the tail gas containing NO_X,in which the inoculated sludge is the activated sludge from the aeration tank for wastewater treatment of a chemical fibre plant.The result shows that after static and dynamic state cultivating,and the formation of membrane,denitrifying bacteria of Brevibacterium can be observed.A higher denitrification efficiency is obtained under a certain inlet gas concentration and controlling suitable pH of circle solution and liquid/gas ratio.The biological method is a workable way to purging the waste gas containing NO_X.
