| 摘 要： | 分析了不同接种污泥下,不同启动策略以及不同水质下SBR反应器亚硝化的启动.研究发现,控制低溶解氧(DO为0.30mg/L)条件,接种具有一定亚硝化效果的污泥,能在短时间内实现亚硝化的启动;而接种全程硝化污泥在29d(58个周期)的培养中都未出现亚硝酸盐的积累.而通过高、低溶解氧交替培养的模式,接种全程硝化污泥的反应器也能在27d(54个周期)内达到60%以上的亚硝化率.接种全程硝化污泥,控制低溶解氧(DO为0.30mg/L),用不同C/N的水质驯化污泥.其中使用C/N为0.40~0.93的A/O生物除磷工艺二级出水作为进水的反应器在32个周期的培养中出水未出现亚硝酸盐的积累;而使用C/N比在3.50~5.34范围内的小区化粪池水能实现亚硝化的快速启动.

| Abstract: | The start-up of nitrosationin SBR was analyzed with different seeding sludge strategy and influent. The results showed the quickly start up of nitrosation when seeding nitrosation sludge with low dissolved oxygen (DO=0.30mg/L) and no accumulation of nitrite when seeding nitrification sludge after 29days (58 cycels) operation.The rate of nitrosation could be above 60% in 27days (54 cycles) when alternative high-low dissolved oxygen was adopted.No nitrite was accumulated when seeding nitrification sludge under low dissolved oxygen (DO=0.30mg/L),with the effluent of A/O biological phosphorus removal process with the C/N of 0.40~0.93 after 32 cycles, while the start-up of nitrosation was realized with the influent from septic tanks with the C/N of 3.50~5.34. |
