Abstract:
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120~180mg/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117~143mg/l，亚硝酸盐和硝酸盐积累较高，总浓度在115~135mg/l；但随着温度升高至44~45℃，亚硝酸盐积累显著下降到5.6~27.9mg/l，no3--n低于2mg/l；至47℃稳定运行期间，no2--n维持在10mg/l以下，no3--n在2mg/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7.16~9.14mg(caco3)/mg(nh4+-n)降至4.08~5.19mg(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.图7参16
