【摘要】 制备聚硅酸硫酸铝镁新型废水处理剂,将其应用于含有酚类污染物的废水处理试验.实验结果表明聚硅酸硫酸铝镁絮凝剂最佳制备Mg/Si摩尔比为1∶1.在pH为7、温度40℃、聚硅酸硫酸铝镁絮凝剂投加量在0.011 mL/mL时,废水中苯酚去除率可达80%以上.实验结果对含酚废水处理有一定指导意义.更多还原

【Abstract】 A new inorganic polymer coagulant polymerized silicate containing aluminium sulfate and magnesium sulfate(PAMSS)were prepared.The effects of ratio of magnesium to silicon(Mg/Si) and acidy on flocculation were investigated.The results shown that the optimum ratio of magnesium to silicon is 1∶1 for PAMSS.The rate of removal phenol is up to 80% under the condion as follows:the amount of PAMSS added is 0.11 mL/mL water,pH value of water is 7 and temperature of water is 40 ℃.更多还原
