摘　　要：在SBR反应器中进行亚硝酸型硝化快速实现的试验研究,结果表明:亚硝酸型硝化的快速实现是包括温度、DO、pH、进水氨氮浓度、SRT等多个影响因素共同作用的结果,其中最主要的是DO和pH.当进水氨氮为120～240 mg/L、SRT约为23d时,控制较低的DO(0.5～1.0 mg/L)和适当的pH(7.5～7.8),在30℃和35℃条件下很容易实现亚硝酸型硝化;在室温条件下(21～25℃),只要控制的pH稍高些(8.0)、DO更低些(0.5～0.6 mg/L),也是可以实现亚硝酸型硝化的.A experiment about fast realization of nitrosofication is carried out in a SBR reactor. It is found that fast realization of nitrosofication is the result of effect of multi-factors such as temperature, DO, pH, SRT and influent ammonium concentration, in which DO and pH are the most important. When ammonium concentration in influent is within 120-240 mg/L and SRT is about 23 d, it is easy to realize nitrosofication at 30°C and 35°C in the condition of low DO(0.5-1.0 mg/L) and appropriate pH(7.5-7.8). A research at room temperature (21°C-25°C) with controlling lower DO(0.5-0.6 mg/L) and higher pH(8.0) is also implemented.
