由于人口增长、工业迅速发展,固体废物不断向土壤表面堆放和倾倒,有害废水不断向土壤中渗透,大气中的有害气体及飘尘也不断随雨水降落在土壤中,导致了土壤污染。目前主要治理污染土壤的方法有物理法、化学法、生物法和等离子体法四种。其中等离子体法是近年来新兴的一种技术,对处理土壤污染有着降解率高,适用范围广且几乎不产生废水、废气和废渣无需添加任何物质等诸多优点,但其不永久性、不稳定性及复杂多样性所造成问题仍需进一步探究解决。 Due to the population growth and the rapid development of industry, solid wastes are piled and dumped on the soil surface continuously, harmful wastewater is continuously permeated into the soil, and harmful gases and dust in the atmosphere are constantly falling on the soil with rain, re-sulting in soil pollution. At present, there are four main methods to control contaminated soil: physical method, chemical method, biological method and plasma method. Among them, plasma method is an emerging technology in recent years, which has a high degradation rate for the treatment of soil pollution, a wide range of application and almost no waste water, waste gas and waste residue without adding any material, etc. However, the problems caused by its imperma-nence, instability and complex diversity still need to be further explored and solved.
