  • 摘要: BAF具有良好的硝化能力。以BAF取代A2N工艺中的接触氧化,在BAF进水前发生有机物和氨氮的分离(碳氮分离),实验研究了碳氮分离对BAF运行特性的影响。结果表明,碳氮分离使硝化段延长1.0m左右,平均提高NH4+-N去除量6mg/L左右;碳氮分离可将BAF柱反冲洗周期延长至7~8d,降低反冲洗用水用气量1/3左右,反冲后30min内即可迅速恢复硝化能力;碳氮分离使BAF柱内硝化菌占据优势,进水端0.3m处,硝化菌比例达到70%,而无碳氮分离情况下,硝化菌比例仅20%。
    Abstract: BAF has good nitrification ability. The contact oxidation was replaced with BAF in A2N process, the influent of BAF occurred separation of carbon and nitrogen. The experiment investigated the influence of the separation of carbon and nitrogen on BAF. The results showed that the separation could extend the length of nitrafication about 1.0 m, and the NH4+-N removal increased by 6.0 mg/L. The backwashing interval was significantly prolonged to 7~8 days, the backwashing process could reduce dosages of air and water by about 1/3 and a quick recovery was observed within 30 min. The nitrifying bacteria dominated along the BAF, the ratio of Autotrophic bacteria increased from 20% to 70% at the inlet side of 0.3 m.
