等离子体电化学法在污水处理中的应用

Application of plasma electrochemical method in sewage treatment

利用等离子体电化学法处理废水具有低能耗、设备简单、处理效率高、对人体及环境无危害的特点.研究以不同浓度的甲基橙(MO)溶液模拟不同浓度有机废水,通过吸收光谱对废水的处理过程进行实时监测,验证了等离子体化学法对污水中的有机物具有较强的分解能力.实验结果表明,经等离子体电化学法处理后的溶液会产生大量的活性物质,这些活性物质可分解污水中的有机物,从而达到污水净化的效果,表现为吸收光谱的吸收峰强度发生明显下降.

The treatment of wastewater by plasma electrochemical method has the characteristics of low energy consumption,simple equipment,high treatment efficiency,and no harm to the human body and the environment.In this study,methyl orange(MO)solution with different concentrations was used to simulate organic wastewater with different concentrations,and the process of wastewater treatment was monitored in real time through absorption spectroscopy,which verifies that the plasma chemistry method has a strong ability to decompose organic compounds in wastewater.The experimental results show that the solution treated by plasma electrochemical method can produce a large amount of active substances,which can decompose the organic matter in the sewage,so as to achieve the effect of sewage purification,which is manifested by the obvious decrease of absorption peak intensity of the absorption spectrum.
