目的　通过探索黄河及制水过程中藻类、藻毒素污染状况和影响因素 ,研究以黄河为生活饮用水源的可行性 ,并针对污染因素制订防治对策。方法　采用现况研究和对照研究 ,对黄河、制水过程中各水质影响因素进行采样分析 ,根据统计的显著性程度 ,对其作出评价。结果　研究表明 ,黄河三门峡段污染严重 ,水质劣于地表水V类标准。传统制水过程中藻类污染严重 ,调蓄池藻毒素年均 32 8.2ng/L、阳性率 80 %。结论　藻类污染已成为地表水源的重要卫生问题 ,国家《生活饮用水卫生标准》尚缺少此项限制标准。地表水藻类密度变化与水温、水体富营养化程度及制水工艺中的截污降浊能力等因素相关 Objective To explore the feasibility of using drinking water source of Yellow River as the source of drinking water in the Yellow River and the process of making water, and to develop control strategies for the pollution factors. Methods Based on the current situation and the comparative study, the influential factors of water quality in the process of Yellow River and water purification were sampled and analyzed, and the water quality was evaluated according to the degree of significance. Results The research shows that the Sanmenxia section of the Yellow River is seriously polluted and its water quality is worse than that of surface water. Algae pollution is serious during the traditional water making process. The average annual volume of algae toxin is 32 8.2 ng / L and the positive rate is 80%. Conclusion Algae pollution has become an important sanitary issue for surface water sources. The national “drinking water health standard” still lacks the restriction standard. The variation of surface water algae density is related to the water temperature, the eutrophication degree of water bodies and the interception and turbidity reduction ability in the water-making process
