等离子体处理危险废弃物的研究

Plasma Treatment of Hazardous Waste

二恶英类物质在有机污染物中毒性最强、对生态环境的影响最大,同时控制难度也最大.如何正确处理二恶英类物质已成为一个重要的环境问题.等离子体是物质的第四态,任何气体通过放电或者加热都可以产生等离子体.利用气体放电产生的热量来处理二恶英等危险废弃物,在此高温下能将有机污染物气体化和玻璃化,从而不产生二恶英.最后介绍了采用热等离子体的焚烧炉与传统焚烧炉比较所具有的优点.

Among the organic pollutants, dioxin - like pollutants have the strongest toxic and exert the biggest influence on ecological environment. They are also the most difficult to control. The proper disposal of the dioxin - like materials has become a crucial environmental problem. Plasma is the fourth state of material and it can be produced through any gas discharge or heating. This study attempts to deal with hazardous waste such as dioxin- like through the heating generated by gas discharge. Under high temperature, the organic pollutants can be gasified and vitrified and thus dioxin - like will not be produced. The paper also describes the advantages of thermal plasma incinerator over the traditional incinerator.
