【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 ~240mg/L、SRT约为 23d时,控制较低的DO(0 .5~1 0mg/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. 6mg/L),也是可以实现亚硝酸型硝化的.更多还原

【Abstract】 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 23d,it is easy to realize nitrosofication at 30 ℃ and 35 ℃ in the condition of low DO(0.5～1.0 mg/L) and appropriate pH(7.5～7.8). A research at room temperature(21～25 ℃)with controlling lower DO(0.5～0.6 mg/L) and higher pH(8.0)is also implemented.更多还原
