During　the　pharmaceutical　intermediate　production,　large　volumes　of　aqueous　waste　with　poisonous　organic　compounds　such　L(+)-alpha-Phenylglycine　are　produced.　In　this　paper,　electron　beam　is　used　for　decomposition　and　toxicity　reduction　of　this　water.　Experiments　we　conducted　in　the　radiation　dynamics　electron　beam　accelerator　with　1.8　MeV.　The　results　showed　that　the　electron　beam　technology　has　high　efficiency　destroying　organic　compounds　even　in　the　presence　of　complex　and　toxicity　effluent.　When　the　electron　beam　irradiation　requires　a　dose　of　1.75kGy,　the　CC　value　of　effluents　from　28380　mg/L　reduces　to　23040　mg/L.　The　more　effective　dose.　is　8.75　kGy,　which　represented　a　reduction　of　toxicity.
