生化处理过程中含氮化合物的相互转换及检测方法探讨

本文介绍了城市污水过程中氮的去除和转化规律及处理过程中的各种影响因素。在处于好氧阶段的反应过程中,在去除有机物和进行磷的吸收的同时,进行硝化反应并且控制硝化反应进行到亚硝酸型硝化结束,然后进行缺氧反硝化,以达到脱氮的目的。在去除有机物的同时,氨氮也有很好的去除效果,在反硝化的过程中,硝化氮被转化成氮气,通过硝化和反硝化,使总氮得到了一定程度的去除。

Mutual Conversion and Detection Methods of Nitrogenous Compounds in the Process of Biological Treatment

This paper describes the rule of removing and transforming nitrogen in urban wastewater and the various influencing factors in the treatment process. In the treatment process of the aerobic stage, while removing organic and absorbing the phosphorus, it conducted and controlled the nitrification reaction until to the end of nitrification nitrite, and then conducted anoxic denitrification, in order to achieve the purpose of nitrogen removal ~ While removing the organic, ammonia nitrogen can also be removed well. In the process of denitrification, nitrification nitrogen is converted into nitrogen gas, through nitrification and denitrification, so that the total nitrogen can be removed to a certain extent.
