厌氧氨氧化在城市生活污水处理中的应用

Application of Anaerobic Ammonia Oxidation in Municipal Domestic Sewage Treatment Plants

伴随着中国国民经济的飞速发展与城市化进程的不断推进,城市生活污水也随之增加,为实现水资源的持续利用与循环发展,探究节能高效的污水处理方式对于国民经济发展及水资源的保护至关重要.近年来,厌氧氨氧化(anaerobic ammonia oxidation,Anammox)工艺作为一种高效节能的污水处理方式已经在垃圾渗滤液、污泥消化液、工业废水等高氨氮废水中得到了广泛的研究,因此结合国内外对于厌氧氨氧化工艺在城市生活污水中的可行性研究及工程应用,分别从厌氧氨氧化微生物群落分布及相互影响、颗粒污泥的影响、组合工艺的性能等角度分析探讨了厌氧氨氧化工艺在城市生活污水中应用的影响因素及前景展望.

With the rapid development of China’s economy and the continuous advancement of the urbanization process,urban domestic sewage also increases. To realize the sustainable utilization and recycling development of water resources,it is essential to explore energy-saving and efficient sewage treatment methods for the development of the national economy and the protection of water resources. In recent years,the anaerobic ammonia oxidation( Anammox) process has been widely studied in the treatment of the high concentrations of ammonia-nitrogen wastewater,such as landfill leachate,sludge digestion liquor and industrial sewage,as an efficient and energy-saving wastewater treatment method.Therefore,combined with the feasibility study and engineering application of the Anammox process in the treatment of the municipal domestic sewage at home and abroad,influential factors and prospects were analyzed and discussed,including the distribution and interaction of anammox microbial communities,the influence of granular sludge,and the performance of the combined process.
