| 摘 要： | 以实际污水厂的水质为原型即在COD为限制因素的条件下,选择乙酸钠作碳源,在实验室规模的序批式反应器（SBR）中研究了进水pH与生物除磷的关系.结果表明,在COD为限制因素的条件下,pH值为7.2时的除磷效果最好;COD/P值越小则聚磷菌在污泥系统中所占的比例越大;低COD/P值下的出水磷浓度、污泥的磷含量和厌氧条件下的COD去除率均较高,但去除单位磷所需的COD量较少,且MLVSS/MLSS值也相对较低.

| Abstract: | Under the condition of real wastewater from a wastewater treatment plant and COD limitation,selecting sodium acetate as carbon source,the study on the relationship between influent pH and Biological Phosphorus Removal(BPR) was conducted in the lab-scale Sequencing Batch Reactor(SBR).It is found that the phosphorus removal effect is best at pH 7.2.When COD/P is lower,i.e.under COD-limiting situation,the phosphate accumulating organisms are dominant,and phosphorus concentration in effluent of low-COD/P system is more than that of high-COD/P system,but less COD is required for the same amount of phosphorus removal.At the same time,lower COD/P causes lower MLVSS/MLSS ratio and higher anaerobic COD removal efficiency. |
