| 摘 要： | 为了考察硫铁比对反硝化脱氮同步除磷效果的影响,进行了不同硫铁比的反硝化脱氮除磷静态实验,并对复合填料系统反硝化脱氮同步除磷作用进行了分析.结果表明,硫铁复合填料的脱氮除磷效果均显著高于单一填料;硫铁比是影响复合填料反硝化脱氮除磷效果的一个关键因素,当硫铁比(体积比)大于等于1∶1时,TN、TP去除率分别达到了85%和97%以上.复合填料脱氮除磷过程均满足二级动力学方程,系统脱氮作用主要依赖于异养反硝化和硫自养反硝化过程,而除磷主要由于海绵铁腐蚀产生的化学除磷作用.

| Abstract: | To study the effects of sulfur/sponge iron ratio on denitrification and phosphorus removal, a series of static experiments were conducted using different ratios of sulfur and sponge iron. The results showed that the denitrification and phosphorus removal effect of sulfur/sponge iron composite fillers was significantly higher than that of single filler, and sulfur/sponge iron ratio was one of the key factors influencing nitrogen and phosphorus removal by composite fillers. When the volume ratio was equal to or greater than 1:1, the removal efficiency of TN and TP reached 85% and 97%, respectively. The denitrification and phosphorus removal process of the composite fillers both fitted second-order kinetic equation, the denitrification was dependent on heterotrophic denitrification and sulfur autotrophic denitrification; the phosphorus removal was mainly chemical phosphorus removal caused by sponge iron corrosion. |
