Comparison of Water Treatment Performance Employ Dielectric Barrier Discharge in Single and Double Dielectric Structure
摘要
Abstract
To research the property of different structure dielectric barrier discharge {DBD} in water treatment,we built a experimental platform that could realize single dielectric barrier discharge and double dielectric barrier discharge. The experimental results show that, to get similar discharge power under the same conditions, the required double dielectric barrier discharge voltage is far higher than single dielectric one; Because of the different parameters such as equivalent capacitance, the discharge voltage, and current waveform under two kinds of structure, the Lissajous figures also have some differences, even though they have certain similarity. In the two kinds of structures, a similar plasma power was used to process 100 mg/L of alkaline magenta solution, and a comparative analysis of the decoloring rate reveals that the number of dielectric does not affect the water treatment effect. The contrast of pH value and chemical oxygen demand （COD} reveals that the chemical reaction under two structures is similar, eventually reaching the purpose of organic pollutant removal. The experimental research and quality analysis between properties of different structure dielectric barrier discharge in water treatment show that the theory about dielectric barrier discharge of sewage treatment is improved, providing a reference for design and optimization of dielectric barrier discharge water treatment equipment.关键词
