当前,给水事业面临的状况是:1.水源污染日益严重;2.水质检测技术发展迅速,能定性定量地鉴别、测量出水中的含微量物质,3.水中有害污染物质对人体健康的影响与危害方面的研究日益深入;4.人们对高质量饮用水的需求日益迫切;5.发展新的高级净水技术和工艺流程日益迫切。 本文拟针对上述情况,从水质角度阐述有关水体原水与饮用水的化学质量标准的若干问题。 1.关于高质量饮用水的目标 高质量饮用水应达到以下几个目标:(1)不含有致病菌、病毒;(2)不含有大量微生物;(3)
At present, the water supply industry is faced with the following problems: 1. Water source pollution is becoming increasingly serious; 2. Water quality detection technology is developing rapidly. It can qualitatively and quantitatively identify and measure micro-substances in water. 3. Impact of harmful pollutants in water on human health and The research on hazards is becoming more and more in-depth; 4. The demand for high-quality drinking water is becoming more and more urgent; 5. The development of new advanced water purification technologies and technological processes is increasingly urgent. This article intends to address the above situation, from the perspective of water quality issues related to the water quality of drinking water and drinking water chemical quality standards. 1. The goal of high-quality drinking water High-quality drinking water should meet the following goals: (1) it should not contain pathogenic bacteria and viruses; (2) it should not contain large amounts of microorganisms; (3)
