为了回收废水中的脂质，对油脂精炼废水的生物吸附处理工艺进行了研究。讨论了影响脂质吸附率和处理后废水COD的几个因素。结果表明，在接种量为1.0×10~7CFU／mL，培养时间和吸附时间分别为12h和36h时，脂质的吸附率和COD的去除率分别达到64.44％和58、9％。由此可见，利用生物吸附回收废水中的脂质潜力巨大，同时可作为高含油废水处理的预处理技术。

The treatment of oil-containlng wastewater from refining factory by bio-adsorption was investigated for reclaiming the lipid. The effects of several process parameters on lipid adsorption rate and COD of treated water were examined. The results showed that the lipid adsorption rate of 64.44% and the COD reduction rate of 58.9% could be achieved at the initial concentration of bacterium QJ3011 of 1.0 × 10^7CFU/mL in wastewater with cultivation for 12 h and adsorption for 36 h. The study suggestes that the bio-adsorption process is a promising t...
