Abstract

A new type of ecological carbon fiber is recently developed in order to increase the treatment efficiency of aquaculture wastewater. In this study, the key experimental parameters are investigated and optimized using the ecological carbon fiber, including the fiber density, the concentration of dissolved oxygen and hydraulic retention time. The performance of aquaculture wastewater treatment was evaluated by measuring the removal efficiencies of COD, ammonia-nitrogen, total phosphorus and turbidity. According to the results, the optimized parameters are obtained with the fiber density of 0.3 kg m-3, the concentration of dissolved oxygen of 6 mg L-1 and the hydraulic retention time of 10 h corresponding to the concentrations of COD, ammonia-nitrogen, total phosphorus and turbidity reduced by 81, 63, 54 and 93 %, respectively, which indicates that the improvement of aquaculture wastewater quality by ecological carbon fiber was significant.
