Decomposition of Dye in Water Solution by PulsedPower Discharge in a Water Droplet Spray通过解决脉冲电力使排放水液滴喷雾染料在水中分解AbstractA method for decomposing dye by spraying watersolution of dye into nonequilibrium plasma in gas phase wasinvestigated using a pulsed-corona discharge reactor.在解决非染料的等离子体以气相形式通过Abstract-A染料喷施清水分解方法采用了一种pulsed-corona放电反应器The corona reactor consists of a discharge wire and a cylindrical electrode.反应器由一个放电电晕线和一个圆柱电极组成The water solution of indigo carmine with a concentration of 20 mg/L was sprayed into the reactor from a showerhead水中靛蓝溶液的浓度与洋红是20毫克/升,由一个小的喷头喷射到反应器中The sprayed water solution was circulated into the reactor喷洒水溶液循环到反应器The dependence of the discharging power injected into the reactor on the decomposition rates of chromogenic and unsaturated bonds in indigo carmine was investigated.对靛蓝胭脂红的发色和不饱和键的分解率由反应器注入放电功率的依赖性进行了研究。Indigo blue was decolored by 1-min circulation with the discharging power of 8.6W. The nuclear magnetic resonance spectrometry showed that indigo carmine was decomposed completely by 60-min treatment.靛蓝脱色1分钟循环与8.6W放电功率。核磁共振光谱表明，经过60分钟处理靛蓝胭脂红完全被分解，The chromogenic and unsaturated bonds were almost decomposed at 9 and360 J/mg, respectively显色和不饱和键几乎分解分别在9和360焦耳/毫克As the discharging power increased, the decomposition rates of both bonds in indigo carmine increased.随着放电功率增加，靛蓝胭脂红溶液的分解率增加。The decomposition rates of the chromogenic bond showed equal values in equal discharging power regardless of the difference of discharge repetition rate and charging voltage of the capacitor.无论在同等功率放电放电重复率和电容充电电压的差别，显色键的分解率呈相等的值。In contrast, the higher repetitive pulses were more effective for the decomposition of the unsaturated bond rather than the magnitude of charging voltage in equal discharging power.相反，较高的重复脉冲使更有效地分解为不饱和键，而不是在同等功率放电的充电电压的幅度。二there is a growing worldwide concern for environment pollution.全球环境的污染受到关注日益增长Commonly used chemicals, such as soaps and detergents, are responsible for the pollution of streams, rivers, and underground water reservoirs.常用的化学物质，如肥皂和洗涤剂，为溪流，河流和地下水库的污染负责Since the dye used in the dye works, e.g., textile dyeing, is one of those chemicals, wastewater,including the dye, must be treated before discharging to the stream or river.由于染料工程中使用的染料，纺织印染，例如，这些化学品，废水，包括染料之一，必须经过处理才排放到溪流或河流The wastewater is treated by biological treatment with microorganisms or by chemical treatment with chlorine Ozone, which is a strong oxidizing agent, is used to destroy pollutants that are resistant to other chemical treatments. 废水处理用微生物或化学处理用含氯臭氧，这是一种强氧化剂，用来销毁其他化学处理能抵抗的污染物的生物处理。In the ozone treatment, ozone is mainly produced by nonthermal plasma and transported as bubbles into the wastewater. The nonthermal plasma produces free radicals of short lifetime and ultraviolet (UV) radiation that is as useful as ozone for water treatment在臭氧化处理，臭氧主要由非热等离子体和运往冲入废水的气泡。非热等离子体产生的自由基的寿命短，紫外线（UV）辐射，如臭氧水处理一样However, the ozone treatment cannot utilize those agents because they have short lifetime.然而，臭氧化处理，不能利用这些药物，因为他们的使用寿命短。In addition, a significant fraction of the produced ozone is wasted because all of the ozone cannot dissolve in water.此外，在产生的臭氧的相当大一部分被浪费了，因为不是所有的臭氧都溶于Wastewater treatment using electrical discharges in water has been developed to improve those issues已经开发放电废水处理以改善这些问题The electrical discharges such as stream discharge produce ozone, freeradicals, UV radiation, and shock waves in water directly如流放电的放电产生臭氧，自由基，紫外线辐射，直接冲击在水中These products or resultants are effective for water treatment这些生成物能有效地处理水However, discharge in water requires a large and expensivepower supply and pulse-forming network, because water hasa much higher breakdown voltage than gas.然而，在污水排放量大时，需要电源和脉冲形成网络，因为水比气体的击穿电压高得多。In this paper, a pulsed-corona discharge reactor is used to produce nonthermal plasma in the gas phase, and wastewater is sprayed into the plasma for treatment 在本文中，脉冲电晕放电反应器用于产生非热等离子体，在气相中，废水喷入等离子体进行处理This system combines the advantages of using a small, simple, and inexpensivepower supply and pulse-forming network for electrical discharges in air and directly utilizing ozone, free radicals, and UV radiation for treating the wastewater. Indigo carmine, used as a coloring agent in food, was selected as the dye in water该系统结合使用小，操作简单，价格低廉的优势电源和脉冲形成网络，在空气中直接利用臭氧放电，自由基，紫外线辐射处理的废水。靛蓝胭脂红，作为食品的着色剂，被选为处理材料。EXPERIMENTAL SETUP 实验装置Fig. 1 shows an experimental setup along with the pulsed-coronareactor.
