Development and Application of Plasma Technology for POPs Waste Treatment in China

Plasma is ionized gas-like substance, comprised by the e-deprived atoms and electron-positron. Plasma possess the characteristics of high energy, high thermal capacity, fast response and electric conversion efficiency, which shows unique advantages and good prospects for the effective disposal of POPs wastes. This paper introduced the basic principle and mechanism of plasma arc technology as a non-combustion technology; reviewed the development of application of plasma technology in the processing of HFC23, organic fluoride industrial waste, phenyl chlorosilane residue, medical waste, printed circuit board, chemical weapons and other hazardous wastes; analyzed the major technical and economic advantages and disadvantages for the plasma technologies in the POPs waste treatment; And corresponding comments and suggestions were proposed to promote the application of plasma technology for POPs waste disposal in China.
