Granular activated carbon (GAC) was modified by microwave irradiation and electrical heating. The characters and toluene adsorption capacity of modified GAC were studied. The results showed that for microwave heating, with the temperature increasing, the activated carbon's ability of toluene adsorption and content of the surface basic functional group were(More)
Used a two-stage bench-scale temperature adjustable biofilter, biological treatment of medium and high concentration waste benzene and toluene vapor was investigated. The inlet vapor concentration (c(i)) was 0.9 - 5.0 g/m3. The results show that the biofilter can obtained good performance at 30 - 40 degrees C, and at 32.8 degrees C for benzene and toluene,(More)
