污水脱氮除磷的研究

Studies of Denitrification and Phosphorus Removal from Wastewater

我国富营养化水体爆发水华和赤潮的水质恶化现象时有发生,而污水中氮磷是水体富营养化的元首。为了水体生态环境不被进一步破坏,详虑水资源再生循环利用,我国各类污水排放标准及再生水回用标准均对氮、磷提出了限值。文章基于污水脱氮除磷机理对其相关处理方法进行综述,以三维电极生物膜法为深度处理方法,提出了优化二级生物处理工艺的发展趋势。

The eutrophication of water body bloom and red tide water quality deterioration are often happened, and nitrogen and phosphorus in sewage is the head of eutrophication. In order to avoid further destruction, considering the water resources recycling use, more kinds of sewage and reclaimed water reuse standards for nitrogen and phosphorus threshold are put forward in our country. The paper based on wastewater denitrification and phosphorus removal mechanism related to its treatment methods were reviewed, with three-dimensional electrode biological membrane method for deep processing, and put forward the optimization of the development trend of the secondary biological treatment process.
