污水生物脱氮除磷工艺研究进展

污水处理的脱氮除磷工艺是中国现阶段的主要研究发展方向,众所周知,污水中的N、P是引起自然水体富营养化的主要原因之一。为了减少中国水体的恶化,中国把污水的排放标准提高,总氮总磷的指标做了进一步的提高。文章从传统脱氮除磷工艺的弊端出发,分别从A2/O工艺优化和新机理阐述了生物脱氮除磷的的研究进展,并做了介绍,同时对今后的脱氮除磷工艺做了展望。

Research Progress on Nitrogen and Phosphorus Removal by Biological Wastewater Treatment

In recent years, the process of wastewater Treatment of nitrogen and phosphorus removal is one of the main research directions, as we known, the nitrogen and phosphorus in wastewater caused by natural currophication is one of the main reasons. In order to reduce the dcterioration in the water, sewage discharge standards and total nitrogen phosphorus index were furthcr improved. The traditional nitrogen phosphorued rcmoval process, the disadvantages respectively from the A2/O process optimization, and expounded the new mechanism of biological nitrogen phosphorus, and research progress were introduced and future nitrogen phosphorus removal process was presented.
