摘要
采用生物膜填料塔进行了净化低浓度苯乙烯废气的实验研究及生物膜内微生物菌群分析.研究结果表明:进口气体中苯乙烯浓度为1 000 mg/m3以下、流量为200 L/h、循环液流量为10 L/h的操作条件下,废气中苯乙烯的去除率可达90%以上.依据实验结果数据,对相关的机理问题进行了分析探讨.
The biofilm micro - community in bio - packing tower is detected and purifying the waste gas of low styrene concentration with bio- packing tower is analyzed. The test results show that when the concentration of styrene in influent gas is below 1 000 mg/m^3, the gas flow is 200 L/h and the liquid flow is 10 L/h, the purification efficiency of styrene in the waste gas can reach 90%. Based on the test data, the related mechanism problems are analyzed and investigated.
