Abstract:

The influential factors of simultaneous removal of phosphorus and nitrogen with denitrifying technique under the condition of lowcarbon source have been studied,based on the relationship of nitryl-nitrogen-phosphorus consumption.The experimental results show that the consumption of nitryl-nitrogen has a linear relationship to the absorbing of phosphorus under the condition oflowcarbon source,simultaneous removal ofphosphorus and nitrogen could be accomplished at anaerobic period as maintaining suitable ratio of nitryl-nitrogen to total phosphorus,but unsuitable controllingofsludge age has a negative effect on the denitrifyingremoval ofphosphorus.

Key words: denitrification, carbonsource, phosphorus removal, nitrogen removal

摘要：

对低碳源条件下反硝化同步除磷脱氮的影响因素进行了研究。结果表明，在低碳源情况下，硝基氮的消耗与磷的吸收呈线性关系，在厌氧段维持合适硝基氮与磷的质量比，可较好地实现同步去除氮磷，而污泥泥龄控制不当则影响反硝化除磷的效果。
