  • 摘要: 选用钛基RuO2-TiO2涂层电极作为三维过电位电解装置的阳极,紫铜作为阴极,活性炭作为第三极,研究了三维过电位电解处理罗丹明B废水的效果,并考察了外加电压、电解时间、初始浓度、pH值和搅拌方式等因素对其处理效果的影响。实验结果表明,外加电压、电解时间和初始浓度等因素均对罗丹明B的降解效果有影响,而pH值、搅拌方式等对罗丹明B的降解效果基本没有影响。与二维电解的对比研究表明,在罗丹明B溶液初始浓度为20 mg/L,电解时间为1 h,电解电压为20 V时,采用二维电解的降解率为20%左右,而三维过电位电解的降解率接近80%。最终产物分析结果显示,经过处理的罗丹明B苯环开环变成直链烃类物质,或者饱和环状有机物,不再具有生物毒性,适合后续的生化处理。
    Abstract: Experimental study was applied for rhodamine B wastewater using a three-dimension-overpotential-electrode electrolysis device which used titanium-based RuO2-TiO2 electrode as the anode, copper as the cathode, and activated carbon as the third pole. The impacts of voltage, electrolysis time, initial concentration, pH and mixing method factors on the degradation effect were investigated. Experimental results indicate that voltage, electrolysis time and initial concentration affect the degradation efficiency of rhodamine B, while pH and mixing method have little effect on the degradation efficiency. The comparative study indicates that with the initial concentration of 20 mg/L, electrolysis time of 1 h, and the electrolysis voltage of 20 V, two-dimension electrolysis degradation rate was about 20%, while the three-dimensional-overpotential-electrode electrolysis was nearly 80%. The final product analysis shows that benzene ring of thodamine B is opened into straight-chain hydrocarbon compounds, or unsaturated cyclic organic compounds through the three-dimension-overpotential-electrode electrolysis, which no longer has the biological toxicity, thus suitable for the subsequent biological treatment process.
