DBD等离子体对蒽醌染料废水的脱色

该文使用了介质阻挡放电低温等离子体对蒽醌染料废水进行脱色，采用酸性艳蓝和酸性紫红作为研究对象，探讨放电功率、电介质间距、放电时间、浓度和pH等因素对脱色性能的影响。结果表明当染料初始浓度为100 mg/L、放电功率为4 kW/L、电介质间距为6 mm时，放电9 min可使蒽醌染料获得98％以上的脱色率。在工程应用中一般要求脱色率达90％左右，此前提下理论能耗为19 kJ左右。

Decolorization of Anthraquinone Dye Wastewater Treatment by DBD Plasma Process

Dielectric barrier discharge low temperature plasma was used to decolorize anthraquinone dyes wastewater in this paper. The acid blue and acid amaranthine were used to represent anthraquinone dyes effluent discoloring performance. Factors such as discharge power,air gaps,discharge time,concentration,and pH value were studied. The results show that when solution concentration is 100 mg/L,discharge power is 4 kW/L,air gaps is 6 mm,decolonization rate of anthraquinone dye wastewater is more than 98% after 9 min. Engineering applications generally requiring decolorization rate of 90%,theoretical energy consumption is about 19 kJ.
