【摘要】 在外直流电场存在下,建立合理的重金属离子由废水溶液本体向生物膜传递及其吸附数学模型,研究外电迁移速度(uy’)、重金属离子初始浓度(c0)、废水流速(u)等对重金属离子传递及生物膜吸附的影响。进而为设计高效的净化含重金属离子废水电-生物膜反应器提供技术指导。更多还原

【Abstract】 In this article, an appropriate transfer and adsorption model of heavy metal ions by biofilm under external direct current field was established, and the effects of electro migration velocity, initial concentration of heavy metal ions and flow rate of wastewater on the transfer and adsorption of heavy metal ions were deeply investigated in order to provide the information for the design of efficient biofilm reactor accelerated by electricity field.更多还原
