| 摘 要： | 将膜生物反应器(MBR)用于高浓度含酚废水的处理中,探讨了进水中苯酚浓度、水力停留时间和污泥浓度对膜生物反应器处理含酚废水效果的影响。实验结果表明:经过42d驯化后,可以在高浓度含酚废水中正常运行,MBR系统对COD和氨氮的去除率分别可达98%和80.6%。当苯酚浓度为134mg/L时,处理的最佳水力停留时间为3h,最佳污泥浓度(MLSS)为7367mg/L。

| Abstract: | Membrane bioreactor(MBR) was applied to the treatment of high-concentration phenolic wastewater in this paper.The effects of phenol concentration,hydraulic retention time(HRT) and mixed liquor suspended solids(MLSS) on degradation were investigated.The results showed that the MBR system could degrade phenolic wastewater well after 42 d domestication of activated sludge.The maximum removal rate of COD and NH3-N of the system were 98% and 80.6%,respectively.When the phenol concentration was 134 mg/L,the optimum HRT is 3h,and the optimum MLSS is about 7367 mg/L. |
