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。The influential factors of simultaneous removal of phosphorus and nitrogen with denitrifying technique under the condition of low carbon 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 of low carbon source, simultaneous removal of phosphorus and nitrogen could be accomplished at anaerobic period as maintaining suitable ratio of nitryl-nitrogen to total phosphorus,but unsuitable controlling of sludge age has a negative effect on the denitrifying removal of phosphorus.
