摘要
证明曝气生物滤池废水深度处理时在适当的条件下能够进行同步硝化反硝化脱氮,影响同步硝化反硝化的因素有温度、溶解氧（DO）、pH值和CODCr/N比等.通过实验得出在温度20~28℃,DO为0.8~1.5mg/L,pH值7.2~8,CODCr/N为6.9~9.2下,同步硝化反硝化作用效果最明显,TN的去除率为最大,平均值分别为63.4%,66.9%,65.5%和67.2%.
The simultaneous nitrification and denitrification （SND） can process in a good condition in water deep treating using Biological Aerated Filter （BAF）. The factors affected SND are temperature, DO, pH and ratio of C/N and so on. The impression of SND is obvious on the condition that the temperature is 20-28℃, DO 0. 8-1.5 mg/L, pH 7. 2-8 and C/N 6. 9-9.2, on which the ratio of TN removal is the highest. The average ratio of TN removal is 63. 4%, 66. 9%, 65.3% and 67. 2% on each condition.
