| 摘 要： | 采用类Fenton氧化-好氧移动床生物膜(MBBR)法处理难降解抗生素发酵废水,探讨了H2O2和草酸投加量对类Fenton氧化工艺以及HRT和曝气量对好氧MBBR反应器的影响.实验结果表明,当类Fenton氧化工艺的最佳操作参数为反应溶液H2O2和草酸初始质量浓度分别为150、45 mg/L、30 W/154 nm紫外灯照射1 h、pH为3.0,在曝气搅拌条件下,COD平均去除率为80.9%.当类Fenton氧化工艺出水pH在7.0时,废水中的污染物还可以进一步被混凝去除.好氧MBBR反应器的最佳工艺参数为HRT 12 h、曝气量0.10 m3/h以及填料填充比(体积比)30%,最终废水COD平均去除率为99.1%,达到<污水综合排放标准>(GB 8978-1996)三级标准要求.

| Abstract: | The enhanced Fenton oxidation and biodegradation in an aerobic moving bed biofilm reactor (MBBR) was employed for the treatment of a high concentration refractory antibiotic fermentation wastewater. The raw wastewater was pretreated by coagulation and sedimentation using polymeric iron sulfate (PFS) as the coagulant to remove about 50% of organic loading and to provide the essential Fe2+ for the subsequent Fenton oxidation,which was enhanced by UV irradiation and the addition of oxalic acid to achieve furth... |
