| 摘 要： | 在滤层厚度等条件一定的情况下，研究了空床停留时间(EBCT)对微量有机污染物,氨氮及亚硝酸盐氮去除效果的影响。结果表明随着EBCT的增加污染物质去除率有所提高,但EBCT大于15min以后,去除率增加不显著。实验条件下，最佳EBCT为15min，该EBCT下出水CODMn、UV254、氨氮、亚硝酸盐氮、去除率分别达到3...

| Abstract: | The thesis analyzes the effect of EBCT on the removal of organic compounds,ammonia-nitrogen and nitrite-nitrogen based on the same thickness of filter layer.The results show that the average removal rates of pollutant grow with the increase of EBCT,however,the affect trails off when EBCT exceeds 15mins.Under the optimal EBCT of 15min,the removal rates of CODMn,UV254,ammonia-nitrogen and nitrite-nitrogen are 32.2%,21.2%,83.2% and 97.3% separately. |
