摘　　要：污水中含有的氮素可以被视作宝贵资源,如何实现从污水中“破坏性”脱氮转变为氮素的深度回收与增值利用,成为水污染控制领域亟待解决的核心问题,也是缓解由于人口膨胀带来的传统资源短缺困境的主要思路。文章以吹脱法、鸟粪石沉淀法、离子交换与吸附法、膜分离法、微生物燃料电池和微藻处理法为例,分析比较不同氮回收技术的适用对象及优缺点,探讨这些技术面临的瓶颈和挑战,最后从回收产品的市场需求和出水水质的角度评价不同技术在污水氮素回收方面的潜力,并展望未来氮回收技术发展趋势。The nitrogen contained in wastewater can be regarded as a valuable resource.How to achieve deep recovery and value-added utilization of nitrogen from destructive nitrogen removal in wastewater has become a core issue that urgently needs to be solved in field of water pollution control,and it is also the main idea to alleviate the traditional resource shortage caused by population expansion.This paper takes ammonia stripping,struvite precipitation method,ion exchange and adsorption,membrane separation,microbial fuel cell and microalgae treatment as examples to analyze and compare the applicable objects of various nitrogen recovery technologies.Their advantages,disadvantages,bottlenecks,and challenges are summarized.Finally,this paper evaluates the potential of different technologies in nitrogen recovery from the perspective of market demanding for recycled products and effluent quality and look forward to the future development trend of nitrogen recovery technology.
