摘要
采用AOMBR处理模拟高氨氮废水,研究了短程硝化反硝化的效果,试验表明:在DO为1.0 mg/L^1.5mg/L,系统温度为28℃,pH控制在7.5到8.6之间,进水NH3-N在598.2 mg/L^701.3 mg/L时,能够迅速启动反应器,在其他工况稳定不变的条件下,探讨了pH、温度和DO等对系统短程硝化稳定运行的影响,并探讨了此过程的影响机理。整个实验过程中,pH和进水氨氮的浓度能够短暂的影响亚硝酸盐的积累,但是并不能长久的使之稳定运行。在形成短程硝化的过程中膜污染逐渐加剧,经过清洗之后膜通量并不能完全恢复。
Using AOMBR processing to simulate the high ammonia nitrogen waste water, studied the shortcut nitrification and denitrification, The results showed that under the condition of DO is 1.0 mg/L - 1.5 mg/L, the system temperature for 28℃, pH in 7. 5 to 8.6, enters water NHz - N when 598.2 -701.3 mg/L, could start the reactor rapidly, In other conditions remain unchanged, Researched the pH, temperature and DO on nitrification and stable operation of the system, and founded the impact of this process mechanism. Throughout the course of the experiment, pH and the concentration of the high ammonia nitrogen waste water to shortcut nitrification impact on the accumulation of nitrite, but can not make long- term stable operation. In the process of the experiment, the membrane foulin gradually intensify, after cleaning membrane flux can not be fully restored.
