生物法同时脱除高温烟气中SO2和NOx的实验研究

Study on biological simultaneous removal of SO2 and NOxfrom high temperature flue gas by biological trickling filter

  • 摘要: 对采用生物膜填料塔处理高温烟气中的SO2和NOx进行了实验研究,结果表明,生物膜填料塔能够有效地同时去除高温烟气中的SO2和NOx.在65 ℃,循环液流量4.0~7.0 L/h,pH=1.5,停留时间150 s,SO2进气质量浓度2 000~3 000 mg/m3,NOx进气质量浓度500~1 000 mg/m3的操作条件下,生物膜填料塔对SO2的去除率可达99.9%以上,对NOx的去除率为60.2%.

     

    Abstract: The biological trickling filter was set up to study the influence factors of technological conditions on simultaneous desulfurization and denitrogenation of high temperature flue gas.The result revealed that sulfur dioxide and nitrogen oxides were simultaneously removed efficiently.The removal rate of SO2 was above 99.9%,and the removal rate of NOx was 60.2%,when temperature was 65 ℃,circulating liquid flow was 4.0—7.0 L/h,pH was 1.5,the residence time was 150 second,and inlet mass concentrations of SO2 and NOx were 2 000—3 000 mg/m3 and 500—1 000 mg/m3,respectively.
