    摘要
  • 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。
    Abstract: In order to improve the removal of total nitrogen from pharmaceutical wastewater, the SBBR based on fibrous fillers was used to treat the actual pharmaceutical wastewater. The test of start-up and domestication lasted for 99 days, and with the initial ammonia nitrogen concentration of (200±20) mg/L in the wastewater, the total nitrogen removal rate of the system was kept at 97% above, without addition of carbon source. When the carbon nitrogen ratio was at 3, the system could not realize advanced nitrogen removal. The denitrification efficiency of the wastewater could be improved by increasing carbon nitrogen ratio. When the carbon nitrogen ratio in wastewater was at 5, the system achieved advanced nitrogen removal. Due to the large quantity of biofilms on the fibrous fillers, the advanced nitrogen removal of SBBR was achieved after the end of aeration. The denitrification pathway gradually changed from SND & endogenous denitrification to SND. The final operation mode was also final determined as feed-stir-aeration-settle-decant.
