초록

Wastewater treatment using ferrate (VI) solution is becoming a promising technology for several years, because it is high efficient and harmless technology. In this study, the ferrate (VI) solution was tested to treatment of desulfurization wastewater. The effluent from desulfurization wastewater treatment process of power plant was used as raw water, and the COD and T-N removal efficiency of ferrate(VI) solution were investigated. In the test, as the injection rate increased from 0.1 to 1.0%, the removal efficiency of COD also slightly increased, about 80% of COD were removed in 1.0% of injection rate. In the case of T-N, about 50% of T-N was removed in the condition of 1.0% of injection rate. The removal efficiency of COD and T-N also affected by reaction time, maximum removal efficiency was shown in 30 min of treatment. From these results, the wastewater treatment with ferrate(VI) solution can be great solutions for treatment of non-biodegradable pollutants in wastewater, especially for the 3rd treatment of wastewater.
