  • 摘要: 通过静态吸附实验,比较了13种不同材质、粒径的颗粒活性炭(granular activated carbon, GAC)对抗生素废水生化出水的吸附效果,选择KC16活性炭作为处理该废水的活性炭。KC16活性炭的进一步静态实验结果表明,当KC16活性炭投加量为30 g/L,吸附时间为6 h时,处理效果较好, TOC、COD、UV254、色度的去除率分别达到了86.99%、88.43%、89.69%和94.08%,并且污染物质(COD、TOC)的吸附符合Langmuir吸附等温式,吸附动力学符合准二级吸附动力学模型(R2>0.99)。动态吸附结果表明,在滤速为1.0 m/h,柱高为1 200 mm时,出水可以达到GB21903-2008《发酵类工业废水污染物排放标准》,处理每吨抗生素废水的活性炭用量为2.45 kg。
    Abstract: A kind of granular activated carbon (GAC), KC16, was selected by batch experiments from thirteen types of GAC with different materials or sizes for advanced treatment of antibiotic wastewater effluent from a combined process of anoxic and membrane bioreactor (MBR). The removal efficiencies of TOC, COD, UV254 and color in the batch experiments reached to as high as 86.99%, 88.43%, 89.69% and 94.08%, respectively, at 30 g/L of KC16 dosage and 6 h of adsorption in batch experiments. The adsorption of pollutants by KC16 met with the Langmuir isotherm and the adsorption process of KC16 fitted a pseudo second-order kinetics model (R2>0.99). The results of the dynamic adsorption experiments with KC16 showed that the effluent met with Discharge Standards of Water Pollutants for Pharmaceutical Industry Fermentation Products Category (GB21903-2008), and the amount of GAC was 2.45 kg for treating 1 ton of antibiotic wastewater under as the filtration rate at 1.0 m/h in the GAC column with the height of 1.2 m.
