由于反硝化的碳源不足,低C/N废水的氮去除较为困难.本研究采用微气泡曝气流化床反应器处理不同C/N的模拟生活废水,评估其运行性能,并进行优势分析.结果表明,在C/N分别为9、4 和3 的时候,微气泡曝气流化床COD平均去除率均在 90%以上,TN平均去除率分别为66.42%、73.11%和77.91%,能够实现较完全的同步硝化反硝化,从而有效地去除废水中的污染物,具有"节能、节材、节地、高效、资源综合利用"的特点.
Performance evaluation and advantage analysis of microbubble aerated fluidized bed reactor
Removing nitrogen from wastewater with low C/N ratio is a difficult task due to the insuffi-cient carbon source available for denitrification.This study used microbubble aeration biological flu-idized bed reactor to treat simulated domestic wastewater with different C/N ratios,and evaluated the operation performance of the reactor,and analyzed the advantages.The results show that when C/N is 9,4 and 3 respectively,the average removal rate of COD in micro-bubble aerated fluidized bed is above 90%,the average removal rates of TN are 66.42%,73.11% and 77.91% respectively,which can realize relatively complete simultaneous nitrification and denitrification,thus effectively removing pollutants in wastewater,and has the characteristics of"energy saving,material saving,land saving,high efficiency and comprehensive utilization of resources".
