摘　　要：为探究磁性颗粒对厌氧氨氧化启动过程的影响,采用2个ASBR反应器进行实验,其中一个反应器不添加磁性颗粒,另一个反应器添加磁性颗粒,初步探明了磁场对ASBR反应器内氮转移过程的影响机理。通过小试方式对比研究了不同磁性颗粒投加量对于反应周期内氨氮和亚硝态氮去除效能以及脱氢酶活性的影响。结果表明,磁场的存在能够促进厌氧氨氧化启动过程中的优势菌落演替以及厌氧氨氧化菌的富集,有效缩短厌氧氨氧化的启动周期;投加30 g/L磁性颗粒可以有效提升微生物的活性,提高反应速率。In order to study the effect of magnetic particles on the start-up process of anaerobic ammonia oxidation(ANAMMOX), two anaerobic sequencing batch reactors(ASBR) were applied to test. One is added with magnetic particles and the other isn’t. The influence mechanism of magnetic field on the nitrogen transfer process in ASBR reactor was explored. The effects of different magnetic particles on the removal of NH3-N and NO2--N in the reaction cycle and dehydrogenase activity were studied by small-scale test. The results show that the existence of magnetic field can promote the succession of dominant communities and the enrichment of ANAMMOX, and effectively shorten the start-up cycle;The addition of 30 g/L magnetic particles can effectively improve the activity of microorganisms and improve the reaction rate.
