摘　　要：在DO,温度,pH,COD一定的条件下,试验了氨氮浓度对复合生物反应器处理废水效能的影响。得出,氨氮去除率随着进水氨氮浓度的增加呈现先上升后缓慢下降的趋势;进水氨氮浓度对COD去除效果的影响较小,去除效率维持在87%～93%之间;某些污染物(如,游离氨和亚硝酸盐)对微生物的抑制与毒性作用都能影响复合生物反应器对污水的处理效果。In the certain condition of DO,temperature,pH and COD,the test on the influence of the concentration of NH4^ ＋ -N to wastewater treatment performance using hybrid biological reactor are made in this paper. Research shows that the NH4^ ＋ -N removal rate increase and slowly downward then with the increase of the concentration of NH4 ^＋ -N in the waste water. The concentration of NH4^ ＋ -N in the waste water has a less influence to the COD removal rate keeping between 87 % to 93 %. The suppres- sion and poisonousness for microorganism of some contamination in the waste water （e. g. ： free ammonia and nitrite） can affect sewage treatment effect of hybrid biological reactor.
