摘　　要：根据盐基度测定以及混凝实验结果,对以赤泥为原料制备水处理混凝剂进行了研究。以碳酸镁为盐基度调整剂,通过正交实验确定混凝剂的最佳聚合条件如下:80℃下,pH=4,聚合时间为24 h,盐基度调整剂的投加量为60 g.L-1。对4种盐基度调整剂(碳酸镁、碳酸钙、氢氧化钙、碳酸钠)制备的混凝剂进行对比,结果发现,以碳酸钠为调整剂所制备的混凝剂盐基度最高,为36.96%,其混凝效果也最好,与市售混凝剂PAC效果相当。Two detection methods, multiple-tube fermentation technique and enzyme substrate technique are applied to thermotolerant coliform bacteria detection in source water, and their detection effects are compared. Results demonstrate that multiple-tube fermentation technique shows equivalence with enzyme substrate technique. It is proposal that enzyme substrate technique can be used as an alternative method to evaluate water microbiological pollution evaluation which comes from fecal.
