摘要
近几年,厌氧氨氧化(Anammox)工艺成为水处理领域的研究热点,因其具有绿色、高效的特点在高氨氮、低碳氮比污水处理方面极具发展前景。但厌氧氨氧化菌生长增殖缓慢且环境敏感度高,导致厌氧氨氧化工艺存在启动时间长、运行失稳等问题,从而制约了该工艺的工程化应用。反应器的选择对厌氧氨氧化工艺启动运行有重要影响,适合的反应器类型主要包括序批式、颗粒污泥、生物膜、膜生物、复合反应器等五大类。从这五类反应器的结构特点和脱氮效果等方面对已取得的成果进行论述,并指出厌氧氨氧化反应器的应用前景及有待解决的技术难题。
In recent years, anaerobic ammonium oxidation(Anammox) process has become a hot spot in the field of water treatment. Due to its green and high-efficient characteristics, Anammox process has a great development prospect in the aspect of treatment for wastewater with high ammonia nitrogen concentrations and low carbon nitrogen ratios. However, due to the slow growth rate and high environmental sensitivity of the Anammox bacteria, the Anammox process has some problems such as long start-up time and unstable operation, which restricts the engineering applications of the process. The selection of reactor has an important influence on the initiation and operation of Anammox process. The suitable reactor types mainly include five categories: sequential batch reactor, granular sludge reactor, biofilm reactor, membrane biofilm reactor and composite reactor. The obtained achievements in the aspects of structural characteristics and nitrogen removal effects for these five types of Anammox reactors are reviewed.Moreover, the application aspects of Anammox reactors and their technical problems to be solved are pointed out.
