【摘要】 １９９１～１９９３年广东省对城市生活饮用水水质进行了系统监测研究。结果表明城市水源水、出厂水、管网水、二次供水合格率为分别为４４．３％、７７．２％、８０．３％、６０．５％。水源水超标指标主要是铁、总大肠菌群、锰、ｐＨ等；出厂水超标指标主要是余氯和四氯化碳；二次洪水和末梢水超标指标主要是细菌学指标。三年来水源水质量有所提高，主要是生物性污染指标含量下降，出厂水、末梢水余氯合格率也有所上升。更多还原

【Abstract】 The Study of the hygienic quality status of the citic drinking water and changing trend were carride out in Guangdong Province in 1991-1993.The results showed that qualified rates of the water source,the produced water, the water supply network and the secondary supply water were 44.3% and 77.2% and 80.3% and 60.5% in city.The indexes of Iron,total coliforms,Manganese’pH et al.in water source,chlorine level and CCl4 in produced water,bacterriology in water supply network and secondary supply could not meet the standared.The contain of COD, NO2,in water source slightly decreased,the qualified rate of chlorine level in produced water and water supply network increased by the year.更多还原
