摘要:
利用筛选的耐高温亚硝化单胞菌结合适量的市政污水厂活性污泥,通过逐步提高温度进行曝气、驯化、挂膜,获得能够在38~47 ℃条件具有高氨氧化活性的硝化生物膜,在进水氨浓度120~180 mg/L,氨氧化率达到90%~99.9%;将该生物膜回复常温硝化,显示其氨氧化活性较差,氨氧化率仅35%~70%. 对其氨氧化产物分析发现,低于43 ℃时被氧化的氨氮为117~143 mg/L,亚硝酸盐和硝酸盐积累较高,总浓度在115~135 mg/L;但随着温度升高至44~45 ℃,亚硝酸盐积累显著下降到5.6~27.9 mg/L,NO3--N低于2 mg/L;至47 ℃稳定运行期间,NO2--N维持在10 mg/L以下,NO3--N在2 mg/L以下. 对反应器中消耗的碱度的分析表明,当温度从43 ℃逐渐升高时,碱度消耗明显下降,由7.16~9.14 mg(CaCO3)/mg(NH4+-N)降至 4.08~5.19 mg(CaCO3)/mg(NH4+-N). 结合大量的NH4+-N被氧化且氨氧化产物中又只有少量的NO2--N和NO3--N,以及碱度消耗明显下降的特征,推测在高温条件下发生了自养硝化反硝化脱氮现象.

Abstract:
Using Nitrosomonas sp. that can endure high temperature and appropriate municipal sludge, a nitrifying biofilm with a high ammonia oxidation capability at 38~47 °C was obtained by aerating, acclimating and coating the biofilm, and gradually increasing temperature. The efficiency of ammonia oxidation was 90%~99.9% when the influent ammonia concentration was 120~180 mg/L. However, when returned to normal temperature, the ammonia oxidation activity of the biofilm decreased and it was only 35%~70%. The analysis of ammonia-oxidizing products in the reactor indicated that when the total concentration of NO2--N and NO3--N was 115~135 mg/L and temperature below 43 °C, the oxidized ammonia reached 117~143 mg/L. When the temperature was increased to 44~45 °C, the concentrations of NO2--N and NO3--N dropped quickly to 5.6~27.9 mg/L and lower than 2 mg/L, respectively. And the concentrations of NO2--N and NO2--N continued to fall to less than 10 mg/L and 2 mg/L, respectively when temperature was increased to 47 °C. At the same time, the analysis of alkalinity in the reactor demonstrated that the consumption of alkalinity was remarkably decreased from 7.16~9.14 to 4.08~5.19 mg (CaCO3)/mg(NH4+-N) with the temperature higher than 43 °C. Based on the less accumulation of NO2--N and NO3--N and the obvious decrease of alkalinity consumption in the ammonia oxidizing process, it was suggested that the autotrophic nitrification-denitrification might take place at high temperature.
