摘　　要：本文论述了超临界流体特别是超临界水在化工环境保护中的应用。分析了超临界流体的特性，介绍了国内外超临界流体降解废弃塑料的工艺和进展，以及超临界水氧化技术（ＳＣＷＯ）在废水和污泥处理中的广泛应用。指出超临界流体技术是环境友好化学的发展趋势，提出我国应大力加强该领域的研究。Application of supercritical fluids (esp. supercritical water) in environment protection and waste treatment is discussed. The character of supercritical fluids is analyzed. The technology of degradation of waste plastic using supercritical fluids all over the world is introduced,and the application of supercritical water oxidation in waste water treatment and sludge treatment is described too. It is concluded that SCF technology is the tendency of environment benign chemistry. We suggest that our country should enhance the SCF study strongly.
