杂色云芝生物滤塔净化甲苯废气效果

为研究生物滤塔中优势菌种杂色云芝净化甲苯的性能。选择松树皮和火山石为生物滤塔填料,杂色云芝为功能微生物,甲苯为目标污染物,研究杂色云芝在生物滤塔中的生长情况及不同停留时间和进气载荷对去除率、去除负荷,系统压降变化的影响等。结果表明：采用强制循环挂膜法,在20 d内即可完成微生物挂膜,且在木质素氧化酶没有参与的条件下杂色云芝生物滤塔对甲苯表现出较好的去除效果。生物滤塔净化过程中气体停留时间（Gas rentention time,GRT）为148.3 s,进口负荷为7.28 g/（m3·h）时,生物滤塔的最大去除能力为6.73 g/（m3·h）,该系统的最高去除率为92.4%;GRT为37.1s...

Summary:为研究生物滤塔中优势菌种杂色云芝净化甲苯的性能。选择松树皮和火山石为生物滤塔填料,杂色云芝为功能微生物,甲苯为目标污染物,研究杂色云芝在生物滤塔中的生长情况及不同停留时间和进气载荷对去除率、去除负荷,系统压降变化的影响等。结果表明：采用强制循环挂膜法,在20 d内即可完成微生物挂膜,且在木质素氧化酶没有参与的条件下杂色云芝生物滤塔对甲苯表现出较好的去除效果。生物滤塔净化过程中气体停留时间（Gas rentention time,GRT）为148.3 s,进口负荷为7.28 g/（m3·h）时,生物滤塔的最大去除能力为6.73 g/（m3·h）,该系统的最高去除率为92.4%;GRT为37.1s,进口负荷为58.25 g/（m3·h）时,生物滤塔的最大去除能力为47.07 g/（m3·h）,去除率在80%以上。试验条件下,系统的压降均在500 Pa以下,说明系统的经济性良好。

Aimed to study the purification performance of the regnant strain Trametes versicolor in biofilter on toluene, the biological filter system packed with pine bark and lava rock was utilized to remove the toluene which was taken as a target pollutant by Trametes versicolor. The pine bark had a higher organic matter content and the lava rock had a bigger mechanical strength. The higher organic matter content could offer more nutrition to microorganism and the bigger mechanical strength could slow down blocking of the biofilter. Toluene is one of the typical contaminants in volatile organic compounds （VOCs） and has a great harm to human health. Biological methods treating low inlet concentration of VOCs have many advantages, such as less investment, low energy consumption, and no secondary pollution.
