| 摘 要： | 采用沸石滤料曝气生物滤池（ZBAF）,对微污染水源水预处理的挂膜启动进行研究。试验结果表明：挂膜过程中CODMn和氨氮的去除率提高不同步,好氧异养菌的增殖速度较快,硝化菌增殖较慢;ZBAF对氨氮具有很好的去除效果,去除率高达90%以上。启动初期对氨氮的去除以离子交换作用为主,末期以硝化作用为主,CODMn的去除一直处于不稳定状态,故对于ZBAF应以氨氮的硝化去除率达到稳定作为挂膜成熟的标志,而不以氨氮总去除率及CODMn去除率作为标志。

| Abstract: | Zeolite biological aerated filter was used in the test of the pre- treatment of micro- polluted source water,and the start -up was studied. The results showed that：the removal of CODM. didn＇t keep in pace with that of NH4＋ -N in the process of film formation. While the increasing rate of the aerobic heterotrophic bacteria is higher than that of the autotrophic nitrobacteria ; ZBAF had a high removal efficiency of NH4 - N, and the removal rate went up to over 90%. Ion exchange was the major contributor to ammonia- nitrogen removal at the beginning,and nitrification reaction played the main role in the end, while the removal of CODM. couldn＇t keep stable, so the end of the start - up phase was basically signaled by nitrification attained stable state not by the total ammonia removal rate and the removal rate of CODMn. |
