摘要
中国许多地区的饮用水水源都受到了不同程度的污染,威胁着人们的饮水安全。对微污染水源水的净化技术成为一项需要迫切解决的课题。论文介绍了中国水资源污染现状以及微污染水中的新型微量有机污染物。分析了中国微污染水源水的特点,介绍了微污染水源水的处理技术,如生物预处理、化学氧化预处理、活性炭吸附、膜过滤、光催化氧化等技术的作用原理,研究与应用。分析了这些技术的优缺点,提出了中国微污染水源水处理技术的发展方向。
Drinking water sources in many areas of China have been polluted to varying degrees, threatening people s drinking water safety. The purification of micro-polluted source water has become an urgently-resolved issue. The paper introduced the status of water pollution in China and the new trace organic pollutants in micro-polluted water. The characteristics of micro-polluted source water in China were analyzed, and the treatment technologies of micro-polluted source water, such as biological pretreatment, chemical oxidation pretreatment, activated carbon adsorption, membrane filtration, photocatalytic oxidation, and the combination of several processes, were introduced. Research and Application. The advantages and disadvantages of these technologies are analyzed, and the development direction of China s micro-polluted source water treatment technology is proposed.
