Abstract: Three high-temperature treatment technologies for spent TBP, including pyrolysis-incineration, steam reforming and super critical water oxidation, are introduced. Steam reforming has the advantages of compact facility, low cost, little secondary waste, high decomposing ratio,and is considered as a technology of superiority. Its development in China is therefore proposed.

Key words: TBP, Pyrolysis-incineration, Steam reforming, Super critical water oxidation
