响应面法优化高原夏菜尾菜废水活性炭脱色工艺的研究

Study on optimization of active carbon discoloration of pleateu summer vegetable processing wastewater by response surface analysis

摘要: 为了有效解决高原夏菜尾菜加工处理过程中废水色度大、不能达标排放的难题,本文以脱色率为评价指标,在单因素实验的基础上,利用响应面法研究活性炭对高原夏菜尾菜废水的脱色条件。得到最佳脱色条件为:活性炭添加量为1.85%,p H为6.1,脱色时间为66min,高原夏菜尾菜废水的脱色率达到85.04%。

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.
