摘要
水中的微量元素是人体微量元素的主要来源。而且饮用水的硬度和总溶解性固体 (TDS)和当地居民心脏病的死亡率有确定的正相关性。TDS越高 ,心脏病发作率越少。健康的水应是去除了有机微污染、三致物质、病原菌、病毒和病原原生动物的 ,并且含有适量微量元素和矿物质的安全和有益于健康的水。饮用水深度净化的目的应是生产出能满足卫生、安全和有益于人体健康的水。
Water is the most important resource of minerals and micro elements for human body.It has been found from some investigations that TDS and hardness of drinking water correlate with the lethal rate of heart disease of the local population.The higher the concentration of TDS,the lower the mortality of heart disese.Therefore, the safe and healthy water should be free of pollutants,such as THMs,virus,bacteria,parasites,heavy metals,radionuclides,nitrite,etc.,and the minerals and micro elements be maintained with in advisirable rang in the water.The advanced water treatment processes mainly including ozonation,biological activated carbon and membrane processes are employed to produce safe and healthy water.
