对Ｗ市三个水厂的水源富营养化及其危害进行了调查分析。结果表明，该三厂水源水域１９９５年污染物输入量总氮１１４１５吨，总磷４５５吨；水中氨氮超标率４８％～１００％，总磷超标率７２％～１００％；该三厂水源已分别达中富、富－重富和重富营养级；水中藻类狂长，有异味，溶解氧降低，水质变差，有机致突变物污染强度明显高于长江水；水经氯消毒后二次污染物浓度增高。作者认为，应加强水源富营养化对饮用水水质和人群健康影响的研究
The water source eutrophication and its damage of three waterworks in W City were investigated and analyzed. The results showed that the total input of nitrogen, nitrogen and nitrogen in the three water sources waters of 1995 was 11,415 tons and 455 tons respectively. The ammonia nitrogen exceeded 48% ~ 100% and the total phosphorus exceeded the standard by 72% ~ 100% Up to the rich, rich - rich and heavy trophic level; water algae mad long, smelly, dissolved oxygen decreased, water quality deteriorated, organic mutagenic pollution intensity was significantly higher than the Yangtze River water; water after chlorine disinfection secondary pollutant concentration increased . The author believes that the study should be strengthened water eutrophication on drinking water quality and population health effects
