摘要
该文研究了三维电极-铁炭微电解复合法对难降解有机物黄连素模拟废水的处理。结果表明三维电极电解技术对黄连素具有较高的脱色效果,在最佳处理条件下黄连素废水脱色率为95%,而COD的去除率仅为38.5%。三维电极与铁炭微电解法复合处理,则可以明显提高黄连素模拟废水COD去除率和废水的可生化性。在最佳条件下COD去除率达到72.3%,废水生化性B/C由原水的0.018提高到0.29。该文还探讨了三维电极与铁炭微电解复合处理提高难降解废水COD去除率和可生化性的原因。
The treatment of berberine wastewater via the combined technology of three-dimensional-electrode and iron-carbon micro-electrolysis was introduced in this paper. The results demonstrate that three-dimensional electrode technique can achieve effi- cient decolorization rate of berberine wastewater, which is 95 % under optimal condition. However, removal rate of COD is only 38.5 %. Via combining three-dimensional electrode technique and iron-carbon micro-electrolysis, the removal rate of COD in berberine wastewater reaches 72.3 % and B/C increases from 0.018 to 0.29 simultaneously. Furthermore, the relevant mechanism was discussed.
