Abstract

In this paper, a method of treating water polluted by persistent pollutants by salinity gradient and generating electricity at the same time is proposed. In fact, a solution of different salinity gradients creates a potential difference between the electrodes, which generates electrical energy by utilizing suitable electrolytes and external circuits. By using the salinity gradient and the REDOX process, the reverse electrodialysis treatment of Cr(VI) wastewater and power generation have been successfully achieved. In this paper, the control variable method is used to investigate the influence of different operating conditions on the reactor performance and Cr (VI) reduction rate. The effects of different concentration gradients, different solution flows and different solution temperatures on the output voltage, internal resistance and maximum power density of the reactor and the Cr (VI) reduction rate were tested. The results show that the salinity gradient and flow rate of the working solution have great influence on the degradation of Cr(VI), while the temperature has little influence on the degradation of Cr(VI).
