【摘要】采用生物膜填料塔净化SO2废气,研究结果表明:其最佳操作条件为入口气体质量浓度500~1 000mg/m3、气体流量100 L/h、循环液流量15 L/h,pH 1.0;当气体流量从100 L/h增加到300 L/h时,SO2净化效率由86.4%下降到73.2%;最佳操作条件下SO2净化效率可达98%以上.更多还原

【Abstract】 An approach to remove low concentration SO₂ using biological trickling filter was studied.The results of preliminary experiment show that the optimum operating conditions are as the following:the concentration of SO₂ in influent gas is 500—1?000?mg/m³,the gas flow is 0.1?m³/h,circulated liquid flow is 15?L/h and pH is 1.0.When the gas flow is changed from 100?L/h to 300?L/h,the SO₂ removal efficiency decrease,from 86.4% to 73.2%,while the concentration of SO₂ in influent gas is about 2?500?mg/m³,the SO₂ removal efficiency can arrive to 90%.更多还原
