摘要:
反硝化除磷技术是目前国内外污水脱氮除磷研究领域的新热点。基于其高效低能耗特性,探讨反硝化除磷的基本原理、介绍几种典型工艺、总结反硝化除磷的影响因素。通过分析认为NO3-和NO2-均可以作为最终电子受体进行缺氧吸磷,提出结合亚硝酸盐型硝化技术以实现短程硝化后的反硝化除磷,从而进一步达到节能降耗的目的。

Abstract:
As a novel wastewater treatment technique,denitrification-dephosphorization has been studied in research field all over the world.Based on its characteristics,such as high efficiency and low energy consumption,the fundamental mechanism of denitrification dephosphorization is discussed,its typical technology is introduced,and its influential factors are summarized.Through analysis,it is indicated that both nitrate and nitrite could be used as final electron acceptors for anoxic and phosphorus absorption.The nitrite-typed nitrification technique is put forward to realize denitrification dephosphorization after short cut nitrification,and,thus,achieve the goal of saving energy and lowering consumption.
