新华社北京8月13日电 随着生活水平日益提高,人们对饮用水的要求也越来越高。越来越多的市民采用购买桶装水的形式来解决饮用水的品质问题。但从水质说,桶装水最佳饮用期为3天,而且一旦开封就要及时用完;就成本而言,桶装水的市场价格为0.4-0.8元/升,成本较高;而且桶装水容易形成二次污染,并且需要提前预订;送水人员混杂,容易带来家庭安全隐患。国内期待能像发达国家一样,水龙头打开就可享用的放心水。
目前中国管道直饮水的瓶颈在于缺乏采用优质管材设立的独立循环式管网,将净化后的优质水送入用户家中(或客房、办公室),供人们直接饮用。
据上海天阳钢管有限公司研发部门负责人介绍,随着人们对健康的热切关注,我国供水领域已经在逐步掀起一场建材行业的绿色革命——限制、淘汰传统的饮用水管(钢筋混凝土管、灰铸铁管、镀锌管、球墨铸铁给水管、硬聚氯乙烯〔PVC-U〕给水管、聚乙烯〔PE〕管)用于日常生活供水系统,取而代之的是环保的、健康的、新型供水管材。天阳不锈钢复合直饮水管在制造和生产过程中无毒废物质产生,使用过程中也不会对水质产生二次污染,优于国家饮用水管道卫生标准,属于绿色环保建材;而且不锈钢复合直饮水管网在后续的运营中,耐腐蚀不结垢,不滋生细菌,完美解决管道结垢、管网堵塞、水质二次污染的问题。
据专家介绍,国内一些走在前列的水务公司,已经将这种性价比优异的直饮水管道大规模升级替代原有落后的管网,让居民们早日享受不出屋门、无须等待、打开水龙头就可以喝到直饮水的幸福生活。
