Excessive nitrogen emissions are a major contributor to water pollution, posing a threat not only to the environment but also to human health. Therefore, achieving deep denitrification of wastewater is of significant importance. Traditional biological denitrification methods have some drawbacks, including long processing times, substantial land requirements, high energy consumption, and high investment and operational costs. In contrast, the novel bio-denitrification technology reduces the traditional processing time and lowers operational and maintenance costs while improving denitrification efficiency. This technology falls within the category of environmentally friendly, low-energy deep denitrification methods. This paper introduces several innovative bio-denitrification technologies and their combinations, conducts a comparative analysis of their denitrification efficiency across various wastewater types, and concludes by outlining the future prospects for the development of these novel bio-denitrification technologies.
过量的氮排放是水污染的主要原因，不仅对环境构成威胁，也对人类健康造成威胁。因此，实现废水的深度脱氮具有重要意义。传统的生物脱氮方法存在一些缺点，包括处理时间长、占地面积大、能源消耗高以及投资和运营成本高。相比之下，新型生物脱氮技术缩短了传统处理时间，降低了运营和维护成本，同时提高了脱氮效率。该技术属于环境友好型、低能耗的深度脱氮方法。本文介绍了几种创新的生物脱氮技术及其组合，对它们在各种废水类型中的脱氮效率进行了比较分析，并最后概述了这些新型生物脱氮技术的未来发展前景。
