| 摘 要： | 通过饮用水除铝的一系列生产实验,主要研究混凝沉淀过程中浊度、pH值等因素对沉淀水余铝的影响.提出除铝可以分为降低溶解铝和去除颗粒铝两种途径.余浊和余铝在一定范围内呈线性相关关系,此时除浊能同时有效去除颗粒铝.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 effect of turbidity on residual aluminum in water was studied through aluminum removal tests in the production of drinking water. Two ways were proposed for the removal of aluminum from drinking water, by reducing dissolved aluminum and by removing aluminum solids. A linear relationship to a certain extent was shown between residual turbidity and residual aluminum in filtered water. Aluminum solids can be removed while turbidity is removed. The optimum 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. |
