摘要
Abstract
In this research,activated carbon electrodes were prepared with mesoporous carbon,and adhesive and conductive materials were applied to remove salt.The effect of the adsorption time,voltage,flow rate and the solution initial concentra-tion on the removal of salt by electro-adsorption was studied.Plant discharged water was treated in order to change it into boiler recycling water through electro-adsorption under optimum conditions.The results demonstrated that the salt removal rate increased with the increase of adsorption time.The adsorption efficiency was enhanced with the increase of voltage,but side reaction like electrolysis occurred under excessive voltage.Desalination efficiency increased with the reduce of elec-trode spacing.The higher the initial concentration of NaCl solution,the greater the adsorption capacity,but the desalination efficiency was reduced,so each device should correspond to one optimal range.In this study,the optimal parameters of the experimental device were determined:the adsorption time should be 40,min,the voltage 1.2,V,and the electrode gap 1,mm.Under the optimum conditions,the treated plant discharged water can meet the using standards for boiler recycling water.关键词
