在我国,随着经济建设的快速发展,水污染呈发展趋势,工业发达地区水域污染尤为严重水,资源短缺问题也日益突出,城市缺水现象越来越严重。农村地区的饮用水问题更为严重。农村地区饮用水的水源呈现分散、多样性和不稳定的特点,水源得不到有效保护,饮水处理往往只经简单的沉淀或澄清处理,不能有效杀灭细菌、病毒等微生物,更不能去除有机农药的残留物,使生活在农村地区的人群的生命健康受到严重影响。
In our country, with the rapid development of economic construction, water pollution shows a trend of development. Water pollution in the developed areas is particularly serious. The problem of shortage of resources is also becoming increasingly prominent. The urban water shortage is worsening. Drinking water problems are even worse in rural areas. Drinking water in rural areas is characterized by decentralized, diversified and unstable water sources. Water sources can not be effectively protected. Drinking water treatment is often simply precipitated or clarified, which can not effectively kill microorganisms such as bacteria and viruses, but can not remove organic Residues of pesticides have seriously affected the lives and health of people living in rural areas.
