摘　　要：通过构建碳纤维填料的接触氧化反应器,与A/O工艺进行对比。通过单因素研究,考察水力停留时间(HRT)与溶解氧(DO)对生活污水COD、氨氮(NH4+-N)和总氮(TN)去除效果的影响。结果表明,在HRT为10 h、DO质量浓度为2.5 mg/L时,接触氧化反应器对COD、NH4+-N和TN的去除率分别为94.75%、88.30%和84.33%;碳纤维填料在水中呈分散状,富集大量的微生物并形成生物膜,具有高生物活性,因此提高了接触氧化反应器脱氮除碳的效率。In this study,a contact oxidation reactor with carbon fiber carrier media was constructed and compared with conventional A/O process.The effects of hydraulic retention time(HRT)and dissolved oxygen(DO)on the removal of COD,NH4+—N and TN in domestic sewage were investigated by single factor study.The results showed that when HRT was 10 h and DO was 2.5 mg/L,the removal rates of COD,NH4+—N and TN were 94.75%,88.30%and 84.33%,respectively.The carbon fiber carrier media was dispersed in water,enriched a large number of microorganisms and formed biofilm,which had high biological activity.Therefore,the efficiency of nitrogen and carbon removal was improved.
