摘要

近年来，常压等离子体技术在水处理领域得到快速发展，具有较好的应用前景，但工业化应用还需降低运行能耗、提高处理效率。以结构复杂、性质稳定的亚甲基蓝模拟染料废水作为实验研究对象，采用易于工业化推广的常压条件下空气介质阻挡放电水处理反应器。研究放电电压、空气体积流量、初始浓度、初始pH值、初始电导率对亚甲基蓝废水处理效果的影响，定量分析·OH在介质阻挡放电反应器处理亚甲基蓝废水过程中的贡献。采用Box-Behnken响应面法，得到系统的最佳运行参数：初始pH值为4、放电电压为13 kV、初始浓度为100 mg/L。结果表明：该装置可以有效处理亚甲基蓝废水，且在最优条件下放电15 min，亚甲基蓝（MB）降解率为95.39%，能量效率为14.87 g/ kWh，反应速率为常数0.202 6 min

，溶液COD值降低了62.63%，色度变化也较为明显，说明该装置可以工业化应用于有机染料废水的处理。

Abstract

In recent decades

atmospheric-pressure plasma technology has been rapidly developed in the field of water treatment

and has a good application prospect

but it still remains a challenge to reduce operating energy consumption and improve processing efficiency for industrial applications. In this paper

a simple and industrially scalable prototype of plasma reactor based on dielectric barrier discharge (DBD) at atmospheric-pressure air condition is employed to the methylene blue(MB) simulated dye wastewater with complex structure and stable performance. The effects of discharge voltage

air volume

initial concentration

initial pH and initial conductivity on the treatment of methylene blue wastewater are studied. The contribution of ·OH in the treatment of methylene blue wastewater by dielectric barrier discharge reactor is quantitatively analyzed. The study further uses the Box-Behnken response surface method to find the optimal operating parameters of the system: initial pH4

discharge voltage 13 kV

initial concentration 100 mg/L. The results show that the device can effectively treat methylene blue wastewater. After 15 minutes of discharge under optimal conditions

the MB degradation rate was 95.39%

the energy efficiency was 14.87 g/kWh

the reaction rate constant was 0.202 6 min

and the reduction rate of the chemical oxygen demand (COD) value is 62.63%

the chromaticity change is also obvious

indicating that the device can be industrially applied to the treatment of organic dye wastewater.
