| 摘 要： | 通过饮用水除铝的生产实验,研究了水温、pH值对残余铝的影响。提出了残余铝随水温升高呈增加趋势、最佳混凝pH值随水温的升高而降低的观点。当水温14℃时,在使用碱式氯化铝时,混凝反应的最佳pH值为7.5。通过调整水的pH值,可以改变溶解铝和颗粒铝的比例,从而改善残余铝的去除率。

| Abstract: | The effects of temperature and pH value of water on residual aluminum have been studied through productive tests of aluminum removal from drinking water,with a viewpoint proposed that residual aluminum tends to increase with the rising of water temperature.When water temperature is 14 ℃and basic aluminum chloride is used,the optimum pH value of water for coagulation reaction is 7.5.By adjusting the pH value of water,the ratio of dissolved aluminum to solid aluminum can be changed,so that the removal rate of residual aluminum can be improved. |
