摘要:
目的 掌握松江区集中式供水企业的基本状况,了解其供水水质卫生指标监测情况,为改善生活饮用水水质提供科学依据。 方法 制作调查表,对松江区19家集中式供水企业的基本情况和供水水质进行现况调查和检测分析。 结果 镇级水厂仅能基本满足目前日常供水需要,突发事件应急处置能力有待提高。19家供水企业的水质检验合格率为63.16%。其中,一般化学指标中不合格项目锰占26.31%、耗氧量占18.75%;非常规检测指标中不合格项目氨氮占11.76%。 结论 对检测结果不合格的指标,供水企业应加速改进制水工艺流程和设备,确保所提供的生活饮用水水质符合卫生标准要求,以保障人民饮水卫生安全。 Abstract:Objective To identify the water quality of central water supply systems in Songjiang District, and provide the scientific basis for further improvement of drinking water quality. Methods Current situation of 19 central water supply systems was surveyed, and the quality of their tap water was monitored. Results These water supply systems in different towns of Songjiang met the basic needs of local residents, but their ability against emergency should be elevated. The water quality in 63.16% of the 19 water systems coincided with the standard, but some of testing indices, such as manganese, chemical oxygen demand (COD)and ammonia nitrogen in product water, and residue chlorine in tap water exceeded the standard limit. Conclusion The water works whose product water quality did not meet the standard should improve their equipments and processing technique, so that to ensure the safety of the drinking water for the people.
