Title Organic membranes coupled with electrochemical study on treatment of organic wastewater containing heavy metal
Abstract
The topic discusses with the coupling of organic membrane and electrochemical to deal with organic wastewater containing heavy metals. Mainly research is on the application of electric field on the electrophoretic migration, electro-coagulation of particles electrochemical oxidation in wastewater to mitigate membrane fouling. By exploring the effect of the electric field filter organic wastewater containing heavy metals through the organic microfiltration membrane, evaluate the filtration performance under different conditions of electric and hydraulic parameters. Experimental study the attenuation of the flux and retention rate of HS and Cu2+ on different voltages, TMPs, and the cross-flow velocities, depending on the size of the retention rate and flux to determine the optimum voltage, TMP, and cross-flow velocity. And observe the morphology of contaminated filtration membrane. Experimental results show that the electric field can reduce the level of membrane fouling. High electric field, TMP and cross-flow velocity of flow in favor of HS migration and cohesion as well as the migration of Cu2+. When voltage of 100V, TMP of 300rpm and the cross-flow velocity of 0.1m/s were applied, the mixture of HS and Cu2+ revealed the best filtering effect. The final interception rate of HS is 91.53%, the removal rate of Cu2+ is 89.85%.
