活性污泥（AS）处理用于去除废水中溶解的碳质需氧量。流出物含有未通过这种处理去除的可溶性有机物以及处理过程中产生的有机物。含有可溶性有机氮（SON）的物质构成了溶解的流出物有机物的很大一部分。之前尚未评估影响 SON 产生和去除的因素。本研究的目的是评估 AS 处理过程中影响 SON 产生和去除的因素，并评估 AS 废水中 SON 的来源。上一篇文章“活性污泥处理过程中可溶性有机氮的产生”中报道了 SON 产生和产生的 SON 来源的研究。本文讨论 SON 去除以及 SON 源对 AS 流出 SON 的贡献。
Activated sludge (AS) treatment is used to remove dissolved carbonaceous oxygen demand from waste waters. Effluents contain soluble organics that are not removed by such treatment and organic matter pro duced during treatment. Material containing soluble organic nitrogen (SON) constitutes a significant frac tion of the dissolved effluent organics. Factors affecting production and removal of SON have not previously been evaluated. The objectives of this research were to evaluate the factors affecting SON production and removal during AS treatment and to evaluate the sources of SON in AS effluents. Studies of SON production and produced SON sources are reported in the preceding article, "Production of soluble organic nitrogen during acti vated sludge treatment." This article addresses SON removal and the contribution of SON sources to AS effluent SON.
