以膨润土为原料制备复合型絮凝剂

Production of a Complex Coagulant from Bentonite

以膨润土为原料,通过酸浸、氧化、聚合等一系列反应制备聚合硫酸铝铁絮凝剂,通过混凝试验考查了其对工业废水的处理效果,得出最佳摩尔比的絮凝剂、最佳投加量、最佳沉降时间和最适宜pH范围,显示了合成的系列絮凝剂对工业废水有较好的处理效果,是一种有广阔应用前景的絮凝剂.

The research is focused on the preparation of complex coagulant from bentonite for disposal of industrial wastewater by a series of ways, such as acid soaking, oxidation, polymerization. The performances of complex coagulants are evaluated through coagulation tests and the optimum conditions such as proportion, dosage, sedimentation time, pH value were determined. These samples exhibit a significantly better coagulation performance in treating industry wastewater under the applied experimental conditions.
