| 摘 要： | 研究厌氧附着膜膨胀床反应器中温处理乳品废水的运行工况。讨论在不同水力停留时间、容积负荷、pH值条件下对COD去除率的影响,并对进出水总氮及氨氮的变化情况进行研究。试验表明:厌氧附着膜膨胀床反应器处理乳品废水,在水力停留时间为8h、中温35℃条件下,COD去处率达到80%以上,对总氮的去除约为8%,出水有机氮的氨化率达70%以上,ρ(BOD)/ρ(COD)由进水的0 5提高到0 8以上。

| Abstract: | The running conditions of Anaerobic Attached microbial Film Expanded Bed (AAFEB) reactor in the treatment of dairy wastewater at moderate temperature are studied. The effects of different HRTs, volume loads,pH values on COD removal rate are discussed as well as the variation of the TN and NH_3-N in influent water and effluent water. The results indicate that, with HRT of 8?h and temperature of 35℃, the COD removal rate is beyond 80%, the removal rate of TN about 8%, the ammonification rate of organic nitration in effluent water above 70%, and ρ(BOD)/ρ(COD) ratio can be raised from 0.5 to above 0.8. |
