摘要
目的了解广州市水源水水质卫生状况,为水污染的治理提供科学依据。方法连续3年每季度对市政水厂的水源水采集一次样本,对水源水进行常规分析。结果3年共采集样本94宗,对32个常规指标和氨氮进行了检测,超标严重的指标依次是色度、混浊度、铝、铁、锰、耗氧量、氨氮、氟化物、细菌总数和粪大肠菌群,合格率在3.13%～93.95%之间,2007年与2005和2006年相比主要超标指标除了铝有所上升外,其余指标均显著降低(P<0.05)。结论广州市水源水的主要污染来源是工业废水和生活污水,主要污染物为有机物。加大治污力度、选取新的水源水,是提高饮用水源水质量的最直接和有效方法。
Objective To investigate the quality of water source in Guangzhou and provide scientific basis for controlling water pollution. Method From 2005 to 2007, samples of water source were collected in every quarter at water treatment plant and analyzed. Result We had collected 94 samples in three years, and tested for 32 general index and ammonia-nitrogen content. The chroma, turbiduty, aluminium, iron, manganese, COD, ammonia-nitrogen, fluoride, aerobic bacterial count, coliform bacteria, fecal coliform indexes were exceed the national standard, with the passing rate of only 3.13.%-93.95%. Conclusion We found that the main pollutant of the water source was organic pollutants. Strengthen the control of water pollution, choosing new water source were the best way to improve the quality of the water supply.
