摘要
综述目前各种低浓度氨氮废水的脱除技术,包括物化脱氮法和生物脱氮法。其中,物化脱氮包括折点氯化法、离子交换法、吸附法、电化学氧化法;生物脱氮包括固定化细胞技术、膜-生物反应器工艺(MBR工艺)、序批式生物膜法(SBBR)、厌氧氨氧化技术。简单阐述各个方法的原理及优缺点,并指出今后研究工作中需要解决的问题。
The current variety of low concentration ammonia wastewater removal technologies, including the physicalchemical methods and biological methods, were reviewed. Among them, the physical-chemical methods of nitrogen removal, including breakpoint chlorination, ion exchange, adsorption and electrochemical oxidation, biological nitrogen removal methods including immobilized cell technology, film-bioreactor technology （MBR process）, sequencing batch biofilm reactor （SBBR）, anaerobic ammonium oxidation technology. The principle and the advantages and disadvantages of each method was briefly discussed, and future research issues need tO be addressed was pointed out.
