摘要构建纳米铁（nZVI）-生物耦合系统，探讨连续流反应器中耦合系统处理刚果红废水的可行性和可控性.研究发现nZVI将刚果红大分子降解为小分子后，提高了废水的可生化性（由0.04提高至0.69）并降低了毒性（由90.25%降至30.57%），为生物单元提供良好的环境条件.反应器连续运行期间，耦合系统对初始浓度为500mg/L的刚果红废水脱色率达99%，COD从167mg/L降低到约50mg/L.而单一生物系统的脱色率仅为30%~70%，COD降至116mg/L，且波动较大.研究结果表明，nZVI-生物耦合系统是一种能够深度处理难降解有机染料废水的技术手段.

Abstract：A coupling system consisting of nano zero valent iron and membrane bioreactor (nZVI-bio system) was constructed to explore the feasibility and controllability of a continuous flow reactor for the treatment of Congo red (CR) wastewater. Since nZVI pretreatment converts CR macromolecules into small molecules, the biodegradability index denoted by BOD₅/COD increased from 0.04 to 0.69 and toxicity reduced from 90.25% to 30.57% compared to the initial CR wastewater, which provides good environmental conditions for biological units. During the continuous operation of the coupling system, CR removal efficiency reached 99% and COD was reduced from 167mg/L to 50mg/L (nZVI pretreatment process at an initial concentration of 500mg/L). However, the color removal efficiency was just 30%~70% and COD was reduced to 116mg/L for a conventional biotreatment system, and the fluctuation is large. The results demonstrated that the nZVI-bio system provides new technical support for deep treatment of refractory organic dyes.
