摘　　要：以低浓度甲苯 (VOC)废气为对象 ,对生物法有机废气净化技术进行了小试、扩试与工业试验的系统研究。低浓度有机废气 (含硫 )的生物法净化工业试验结果表明 ,该装置连续运行 10 0d ,对于甲苯浓度为30 0～ 140 0mg/m3 的橡胶再生低浓度有机废气具有良好的净化作用 ,净化效率可较长时间保持在 90 %左右 ,废气经生化处理后可以实现达标排放。By means of lab test, enlarged test and industrial test of biopurifying the waste gas containing toluene (VOC) in low concentration, the biopurifying technology of organic waste gas was researched systematically. In a rubber\|regeneration factory, the industrial test on purifying the low concentration organic waste gas (containing sulfur) from rubber\|regeneration process by using biochemical method was carried through. For the waste gas containing toluene in a range of 300～1400 mg/m 3, the industrial test device showed a good purification capacity. The result of 100 d test running with the device indicated that the purification efficiency of toluene in the rubber\|regeneration waste gas could be kept at 90 % for a long time and the treated waste gas could be discharged in the situation of satisfying the National Emission Standard. The biopurifying technology of waste gas displayed its good advancement of technology and rationality of economy. [
