【摘要】 热等离子体技术是一种用来处理工业危险废物的新兴技术,国内外研究机构做了大量研究工作并取得了一定的成果。介绍了等离子体的相关概念与热等离子体技术的优点和工艺路线,并对热等离子体技术在石化与冶金危废处理、催化剂贵金属回收、铬渣的资源利用、土壤修复以及废液处理等领域的应用进行了详细的介绍与分析。由于满足不断严苛的环保要求和符合可持续发展,热等离子体技术在危废市场的发展前景广阔,但推动热等离子体技术市场化需要进一步提高效率并降低成本。更多还原

【Abstract】 Thermal plasma technology is an emerging technology to treat industrial hazardous wastes. Chinese and foreign research institutes and organizations have performed a great deal of research works and achieved certain progresses.This paper introduces the concern concepts of plasma,and the advantages and process routes of thermal plasma technology.Particularly,it describes and analyzes in detail the applications of thermal plasma technology in the aspects of hazardous wastes treatment in the petrochemical and metallurgical industries,recovering noble metals from exhausted catalysts,recycle of chromium slag,soil repair and liquid wastes disposal. The thermal plasma technology has promising prospects in hazardous wastes treatment market because it can meet the increasingly stringent environmental requirements and compliance with sustainable development. However,higher efficiency and lower cost are needed for promoting thermal plasma technology into wider market.更多还原
