我国水资源污染与饮用水安全性研究

对我国水资源状况和饮用水安全性进行了分析研究,结果表明：我国水资源贫乏,水资源环境污染日益严重。许多水厂不得不面临着使用更多的水质不符合要求的受污染水源原水作为生活饮用水水源。水污染主要是有机物和氨氮污染,常规净水工艺系统难以将这些污染物有效除去,降低了饮用水水质,对人体健康构成潜在威胁。随着人们生活水平的提高和健康安全意识的不断增强,对饮用水水质标准提出了更高要求。为从受污染的水源原水中除去对人体健康有害的污染物,提高饮用水的安全可靠性,强化传统工艺、替换传统的消毒剂、吸附、膜过滤和生物预处理等净水技术得到了国内外广泛重视和关注,尤其是经济、高效的生物除污染技术。

POLLUTION OF WATER RESOURCE AND THE SAFETY OF DRINKING WATER

The water resource have been relatively poor in China,while the problem of water pollution has been serious .Some polluted water may have been used as the sources for drinking water. Organics and NH++-4N are the main pollutants in water sources,but it is very difficult for the traditional water treatment system to effectively remove these pollutants. The drinking water quality may have decreased and been the latent menace to human health with the increase of the living standard and the health safety level in China.In order to remove pollutants harmful to human health from the polluted raw water in the water sources and improve the safety properties of the drinking water, it is widely emphasized all over the world to strengthen traditional water purification process,to replace traditional disinfectants,to improve adsorption process,and to introduce membrane filtration and biological pretreatment,etc,especially the econmic and high efficient biological processes in removing pollutants from the drinking water.
