Nitrogen cycling during wastewater treatment Dawn E. Holmes, ... Jessica A. Smith, in Advances in Applied Microbiology, 2019 1.2 Excessive reactive nitrogen damages ecosystems Although reactive nitrogen is a necessary component of life, an excess of reactive nitrogen can cause serious environmental pro...
Nitrogen-cycling microorganisms play essential roles in biological wastewater treatment, where nitrogen is removed with substantial energy and chemical consumption and greenhouse gas emissions. The discoveries of new nitrogen-cycling microorganisms paved the way for a remarkable paradigm shift from energy-nega...

Bioreactors in which excess microbial biomass (sludge) produced during wastewater treatment is anaerobically converted to carbon dioxide, methane, ammonium and reduced sulfur compounds. Primary nitrite maxima The peak in nitrite concentrations at the base of the euphotic zone. ...
This paper introduces nitrogen cycling and nitrous oxide production and reviews the research currently available onN2Oemissions from wastewater treatment operations, landfilling, composting, and incineration; demonstrating that each process can emit large amounts of this important gas. This is followed by ...

(Color online) Development of biological technology for municipal wastewater treatment.随着工业生产快速发展, 水体富营养化在全球范围爆发, 污水的脱氮除磷处理成为世界性普遍需求. 城市污水处理目标也由单一的有机物和悬浮固体去除, 转变为碳、氮、磷污染物的同步削减, 处理工艺的发展由此进入以脱氮除磷为关键环...
and the analysis and control of its pollution in the environment have become a research hotspot in the field. The nitrogen transformation and nitrogen cycling in the environment are mainly driven by microorganisms in the environment, and the existence of microplastics can affect the microbial populatio...
cycling of nitrogen. These latter processes lead to a loss of usable fixed nitrogen from the soil. Overall, the input rate from biological, spontaneous (e.g., lightning), and industrialnitrogen fertilizer(by the Haber–Bosch process) production is slightly higher than the loss rate. Of these,...
