Based on two-phase anaerobic mechanism, a processing reactor was designed;and the waste water with high concentration discharged in the process of production of Chinese traditional medicine is carefully analyzed by the use of GC-MS.The results obtained in the experiment show that the by-products of hydrolization and acidification increase instead of the reduction of organic matters' sort,and at the same time that the number and the amount of compounds in the eventual processed water are apparently reduced,the acid-producing reactor may decompose compounds with great molecule into those with small molecule and accordingly improve the biologically processing ability.
