Abstract

In order to solve the discharge problem of pleateu summer vegetable processing wastewater due to high chroma,decolorization rate was taken as indexes to evaluate the effect of decolorization in this study,and the conditions of the active carbon decoloring process were optimizated by response surface analysis. And then optimal decoloration conditions were as follows:activated carbon dosage was 1.85%,decoloration p H was6.1,decoloration time was 66 min. In further verified experiment the decolorization rate was 85.04% under the optimal conditions.
