摘　　要：水源水中多数金属元素含量是符合水质标准的,但像铁、铝、锰、钛这些地壳中较丰富的元素可能超过相应水质标准。试验以浊度作为净水工艺的主要控制指标,分析以上金属元素与浊度之间的关系。结果表明,铁、铝、钛的含量与浊度之间呈明显的正相关关系;以金属钛作为控制指标时,浊度也符合相应水质要求。该成果可简化以松花江为地表水源水的中小型水厂的日常检测,并且对检测能力一般的水厂的运行管理也具有指导意义。The concentrations of most metals in raw water are within the water quality standard. However, metals such as iron, aluminum, manganese and titanium may exceed the drinking water quality limits. Turbidity is a major controlling index in water purification process design. Hence, the correlation between metals and turbidity was studied. The results showed that there was a positive correlation be- tween the metal concentrations and the turbidity. When titanium was used as a controlling indicator, the turbidity could reach the standard as well. For small to medium sized water plants using the Soughua Riv- er as raw water, this study showed that daily testing routines could be simplified. Guidance in general op- eration and management were provided for water plants with limited testing capacity.
