| 中文摘要 | Dye wastewater pose high pH and strong color to the environment. Single process for treatment of dye wastewater would be inefficient. Large amount of dosages for neutralization and chemical treatment are required, leading to the rapid increase of the cost of treatment. In this study, a combined adsorption/coagulation process was studied by using magnesia as an adsorbent and polyaluminum chloride (PACl) as a coagulant. The removal of C.I.Reactive Red 120 was optimized using response surface methodology (RSM). The effect of treatment sequence, pH, dosages and initial dye concentration were investigated. It was indicated that dosing magnesia before PACl was more efficient than dosing PACl before magnesia. The optimal conditions obtained were as follows: magnesia dosage 2.5 gl(-1), PACl dosage 15x10(-3) gl(-1) and pH 12.0. Under the optimal conditions, more than 80% of dye removal efficiency was achieved as the initial dye concentration increased from 0.1 to 2 gl(-1). Based on these results, low-cost materials were applied and the dosages were optimized. The adsorption/coagulation process was considered to be cost-effective. The disadvantages of a single process were overcome and significant dye removal efficiency was obtained in the alkaline pH range. Therefore, alkaline dye waste was quite suitable to be treated with the process without neutralization. |
