ABSTRACT:Degradation process of methyl violet waste water through the activated sludge treatment was investigated in a new kind of jet loop three phase bioreactors, using cattle dung slurry as the source of activated sludge and the coal powder as biological carrier. The optimized degradation conditions were determined as follows: pH=6.5～7.5, temperature=28 ℃, gas flux=1.5 m3．h-1. The decolorized degree in this degradation process was up to 94%, and the decrease of CODcr was about 62% during the continuous degradation process. The kinetic equation of methyl violet waste degradation was obtained by experiments:
