摘要
将天然硅藻土用Mg(OH)2改性后制成Mg(OH)2改性硅藻土,以处理活性染料的染色废水。分析了各种处理条件如Mg(OH)2改性硅藻土的投加浓度、吸附时间、初始p H值、处理温度对以处理后的活性染料染色废水的脱色率和吸附量的影响。得出的结论是:当Mg(OH)2改性硅藻土的投加量为13g/L、时间为10h、初始p H值为10、温度为20℃时,对活性染料废水处理后的脱色率和吸附量较好。
In this paper, magnesium hydroxide-modified diatomite, which was modified by magnesium hydroxide, was ap- plied to tackle reactive dyeing wastewater; The effect of treatment condition such as concentration of magnesium hydroxide- modified diatomite, treatment time, treatment initial pH, treatment temperature for decoloring rate and absorption quantity of reactive dyeing wastewater was discussed. The conclusion is that： the treatment-effictiveness for decoloring rate and absorption quantity of reactive dyeing wastewater is optimum when concentration of magnesium hydroxide-modified diatomite is 13g/L, treatment time is 10h, treatment initial pH is 10, treatment temperature is 20℃.
