EXPERIMENTAL STUDY OF DYE WASTEWATER TREATMENT BY NEEDLE-PLATE PULSED DISCHARGE

摘要：

The influences of pulsed voltage，pulsed frequency,needle-plate spacing and rate of bubbling of a needle-plate pulsed discharge reactor on decoioration efficiency of Rhodamine B in aqueous solution have been studied by experimental research.Test results indicate that the decoloration efficiency of Rhodamine B is up to 99.68％and the TOC of the solution decreases to 19.2mg/L from 70mg/L under the optimal condition that pulsed voltage is 32.5kV, pulsed frequency is 60Hz,needle-plate spacing is 15cm，rate of bubbling is 12L/h and treatment time is 50min.Pulsed discharge for decoloration of hybrid aqueous solution of three dyes(e.g.，Rhodamine B，Methylene Blue，Methyl Oange)also has been studied.Results show that the pulsed discharge plasma treatment is efficient for aqueous solution decoloration of various textile dyes，and decoloration efficiencies of them are 99.75％，98.64％ and 97％ respectively.
