Abstract:Reverse electrodialysis reactor (REDR) can convert the concentration gradient energy of the working fluids into the degradation energy of organic matters in wastewater. In order to verify this energy conversion process, the experiments on the degradation of phenol wastewater in the cathodic and anodic independent loops of REDR powered by concentration gradient energy were conducted. The single-factor analysis was adopted to evaluate the effects of changes in the components of simulated wastewater and operating parameters on phenol degradation. The results indicated that each cathodic and anodic independent loop of REDR could effectively degrade the phenol in the simulated wastewater. Within the ranges of imposed component concentration and operational parameters, at the REDR output current density of 20 A·m~(-2), the optimum component concentration in simulated wastewater and the operating parameters, the maximum phenol removal rates in each degradation loop could reached 98.1% and 100% after 80 minute-oxidation reaction in 500 mL of 50 mg·L~(-1) phenol simulated wastewater, respectively.
