摘要：采用UV_(185 nm)-H_2O_2组合工艺处理高浓度棘白菌素类抗生素发酵废水。结果表明:UV_(185 nm)-H_2O_2组合工艺较好地实现了高浓度棘白菌素类抗生素发酵废水的强化处理,其处理效果明显优于单独UV_(185 nm)光氧化工艺;在废水pH为2.50、光照时间为60 min、H_2O_2投加量为5 g/L、反应温度为室温的条件下,UV_(185 nm)-H_2O_2组合工艺对废水色度和COD的去除率分别高达96.4%和46.9%;该联合氧化过程需在酸性体系中进行;联合氧化过程中产生了大量蜂王浆提取物类黑褐色物质,处理出水中显色物质的种类明显减少,实现了废水的高效脱色。
The high-concentration eehinocandin antibiotic fermentation wastewater was treated by UV185 nm-H2O2 combined process. The results showed that： The treatment of the wastewater was enhanced by UV185nm-H2O2 combined process, and the treatment effect by the combined process was much higher than that by UV185 nm photooxidation process; Under the conditions of wastewater pH 2.50, irradiation time 60 min, H2O2 amount 5 g/L and room temperature, the removal rate of chroma and COD of the wastewater were up to 96.4% and 46.9% respectively; The combined oxidation process should be carried out in acidic system; A large amount of royal-jelly-extract-like dark brown sediment was generated in the combined oxidation process, and the colored substances in the effluent were reduced obviously, thus the wastewater was decolorized effectively.
