摘要：

结合电解处理技术和植物修复技术理论，建立了植物-电解联合净化系统，并用于对混合偶氮染料溶液的处理实验。结果表明，偶氮染料废水经植物-电解联合净化后水质更加稳定，脱色率和COD去除率最高分别可达98.7%和85%；出水微生物抑制率和生物抗过氧化能力显著降低，出水苯二胺和芳香胺类物质残留最大削减量分别为81.25%和99.17%。

Abstract:

Combining electrolysis treatment technique with phytoremediation technique,the plants-electrolysis united purification system has been set up and used for the treatment experiments of mixed azo dye solution. The results show that after azo dye wastewater has been purified jointly by plant-electrolysis process,the water quality becomes more steady. Its maximum decolorization rate and COD removing rate can reach 98.7% and 85%,respectively. The effluent microorganism inhibiting rate and biological over-oxidation ability are decreased obviously. The maximum reduction rates of effluent diphenylamine and aromatic amines substance residues are 81.25% and 99.17%,respectively.

Key words: azo dye wastewater, plants-electrolysis system, microbial toxicity, decolorization rate, oxidative stress
