START-UP OF SBBR BASED ON FIBROUS FILLERS TO ACHIEVE ADVANCED NITROGEN REMOVAL FROM PHARMACEUTICAL WASTEWATER

  • 摘要: 针对制药废水总氮去除难的问题,采用纤维填料SBBR工艺处理实际制药废水。启动和驯化实验共进行了99 d,在制药废水NH3-N浓度(200±20) mg/L的条件下,最终系统的TN去除率稳定在97%以上,且未添加任何碳源。废水C/N是影响深度脱氮的关键条件,在进水C/N为3的条件下,系统无法实现废水的深度脱氮。通过提高废水的C/N,可以提高废水的脱氮效率。当废水C/N为5时,系统实现了深度脱氮。得益于纤维填料上大量的生物膜,SBBR在曝气结束后即实现了深度脱氮,脱氮的途径由同步硝化反硝化+内源反硝化逐渐转变成同步硝化反硝化。操作模式也最终确定为进水-搅拌-曝气-沉淀-排水。
