生物碳导电剂增强印染废水脱盐性能研究
Bio-Carbon as Conductive Agent for Desalination of Printing and Dyeing Wastewater
摘要
Abstract
Flow electrode capacitive deionization(FCDI)technology is an efficient desalting technology for wastewater treatment.However,low electrical conductivity of flow electrode slurry caused low current u-tilization rate and poor desalination performance.Therefore,the cellulosic biomass carbon materials such as carbonized bacterial cellulose(CBC),carbonized chitin(CCH)and carbonized straw(CSW)are intro-duced in flow electrode as conductive agents to improve the utilization rate of active materials(Activated carbon,AC).The results showed that the group of 5 AC with 0.25 CBC could obtain a higher salt ion re-moval rate(1.26～5.92 mmol·L-1·(m2·s)-1)than only group of 5 AC-only(0.09～2.58 mmol·L-1 ·(m2·s)-1)under saline water concentration ranged from 1.01～35.00 g/L at 1.8 V.Electrochemical and physical characterization analysis further revealed that the introduction of CBC can more availably generate an interconnected conductive network than spherical carbon black particles(CB)and thus enhances the o-verall conductivity of the flow-electrode slurry.Finally,the established FCDI system shows excellent per-formance and potential applications in the desalination of printing and dyeing tail water.关键词
