摘要
Simulation tests were employed in the treatment of wastewater from seawater that was received from a specific power plant via flue gas desulfurization (FGD) for wastewater purification in this study. After water quality and compound variation were confirmed, a simulation was conducted to investigate the efficacy of pre-processing on the elimination of the majority of pollutants, like suspended solids, calcium ions, and magnesium ions. A mini scale electrodialysis reversal (EDR) mold plant was used to eliminate target pollutants, including sulfate and chloride ions. The Taguchi method was used to determine the optimal operating conditions that applied to various operating parameters, including temperature, flow rate, voltage, and current durations of power supply, to obtain the optimal operating parameters through analysis of variance (Minitab 14.0) simulation. After the simulations, the optimal parameters in the EDR process were used to demonstrate the removal efficiency of chloride, sulfate, and conductivity following treatment by EDR. The optimal operating parameters of the Taguchi method were 1 V (voltage), 3 L min(-1) (flow rate), 15 degrees C (temperature), 30 min (duration of power on), and 2 min (duration of power off). Combining the Taguchi method with the EDR process on wastewater treatment not only decreased initial conductivity from 4860 to 450 mu S cm-(1), but also alleviated concentrations of sulfate and chloride ions.
