【摘要】 针对天津市的水源情况,分析评价了1996-2005年10年期间滦河原水和黄河原水的水质变化特点.结果表明,天津市的水源水质普遍存在低温低浊、高藻、微污染的特点.采用Kmeans聚类法对水源水质进行水质分期,把滦河原水划分为3个水质期,黄河原水划分为2个水质期,并对每个水质期的水质特点进行分析和评价,对水厂运行工艺及参数的调整起到一定的指导作用.更多还原

【Abstract】 Water quality in the past 10 years(1996—2005) in the Luanhe River and Yellow River,the main water supply sources of Tianjin city,are analyzed and discussed.The result shows that the raw water its quality are characterized by low temperature and low turbidity,high algae-laden,and micro-polluted.The Kmeans clustering method is applied to divide the time into 3 stages for the Luanhe River raw water,and 2 stages for the Yellow River raw water.At the same time,analysis and evaluation of its water quality in each stage is assessed,providing the reference for adjusting the water plant’s treatment process and running parameters.更多还原
