Abstract

Nitrate, as a common pollutant in surface water and groundwater, not only causes aquatic ecosystem problems such as eutrophication of water bodies, but also poses a threat to human health. This article reviews various treatment technologies for nitrate wastewater, covering three methods: physical, chemical and biological. Among them, the denitrification process is one of the effective ways to treat wastewater with a low carbon-nitrogen ratio and has significant advantages. This paper first systematically introduces the principles and applications of various methods for treating nitrate wastewater, with a focus on discussing the good performance of different methods in the nitrate removal process and the key strategies to improve their removal efficiency. Finally, a comprehensive summary of various methods was conducted, and prospects were made for the existing problems and future research directions, aiming to provide a theoretical basis and reference for the efficient removal of nitrate in water bodies.
