| 摘 要： | 针对低污染原水进行叠式曝气生物滤池的自然挂膜启动实验。在HRT为20～30 min,温度为28～33℃,气水比为0.5,滤速为12.5 m/h的条件下,研究分析叠式曝气生物滤池在自然挂膜启动过程中各项水质指标的变化情况与生物膜生长之间的相互关系,判断挂膜启动的进程。结果表明,在南方夏季,叠式曝气生物滤池能够进行快速启动,经过7 d左右自然挂膜启动完成,对CODMn的平均去除率为33%,对氨氮的平均去除率达到85.5%,对亚硝酸盐氮的去除率为82.9%。

| Abstract: | Specific to the micro-polluted raw water,the experiment of natural start-up was used to down-up biological aerated filter(D-UBAF).Under the conditions of HRT of 20~30 min,the water temperature of 15~22 ℃,the gas water ratio of 0.5,and a filtration rate of 12.5 m/h,the relationship between the change condition of the different water quality index and the growth of biomembrane was researched and analyzed to estimate the course in the D-UBAF during the process of natural start-up.The result showed that D-UBAF could be started quickly,and natural start-up was completed after 7 days in the southern summer.The average CODMn removal rate of raw water was 33%,ammonia nitrogen removal rate was 85.5% and nitrite nitrogen removal rate was 82.9%. |
