水是生命之源,获得安全饮用水是人类生存的基本需求。由于受气候、地形、水文地质等因素和经济、技术等条件的制约,以及人类活动的负面影响,我国农村供水总体水平不高,部分农民的引水问题历来严重。主要表现在自来水普及率较低,水源中氟、砷、铁、锰、含盐量、细菌或有机物等有害物质超标,普遍缺乏必要的水处理和消毒设施,长期以来农村居民以传统、落后的分散式供水为主,多数农村或农户的供水设施简陋,且管理落后,造成供(饮)水水质超标、季节性缺水严重或工程不可持续利用。目前,我国农村尚有3亿多人饮水严重不安全。
Water is the source of life, and access to safe drinking water is a basic requirement of human existence. Due to the constraints of climate, topography, hydrogeology and other economic, technical and other conditions and the negative impact of human activities, the water supply in rural areas of our country is generally not high, and the water diversion problems of some peasants have always been serious. Mainly manifested in the low penetration rate of tap water. In the water sources, fluorine, arsenic, iron, manganese, salt content, excessive quantities of harmful substances such as bacteria and organic matter are over-standard and the necessary water treatment and disinfection facilities are generally lacking. For a long time, rural residents, Distributed water supply is the mainstay. Most villages or rural households have poor water supply facilities and backward management, resulting in excessive supply of drinking water, serious seasonal water shortage or unsustainable use of the project. At present, there are still over 300 million people in rural areas in China who have serious unsafe drinking water.
