我国城市自来水水质明显低于国外发达国家。这一方面是由于我国多数水源的原水水质相对较低、污染严重、水中浊度和色度及有机物浓度偏高；另一方面是由于我国绝大多数水厂仍然主要采用的是常规给水处理工艺，对某些特殊有机污染物的去除效果有限，难以充分适应不断变化的水质。由于污水处理设施建设的长期欠缺，加上工程投资大、运行管理费用高，因而我国的污水处理率在短时期内难以得到明显提高，在今后相当长时期内，对于微污染水（含有微量污染物的水）的净化处理将是一个重要的研究课题。目前制约饮用水处理领域的科技问题可以归纳为以下几个方面： The water quality of urban water in China is significantly lower than that of developed countries. On the one hand, the water quality of the majority of water source in China is relatively low, the pollution is serious, the turbidity and chromaticity of the water and the organic concentration are on the high side. On the other hand is due to the vast majority of the waterworks in our country is still mainly adopts conventional water treatment process, for some special organic pollutants removal efficiency is limited, it is difficult to fully adapt to the changing of water quality. Due to long-term lack of sewage treatment facilities construction, coupled with the high cost of project investment, operation management, therefore our country's sewage treatment is difficult to get improved in a short period of time, quite a long period of time in the future, for the slightly polluted water (water) containing trace pollutants purification treatment is an important research subject. The technical problems that restrict drinking water treatment can be summarized as follows: （1）水中微量有机污染物去除的工艺理论与技术； (1) process theory and technology for the removal of trace organic pollutants in water; （2）水中藻类及其代谢产物（嗅味、藻毒素等）的强化处理技术； (2) enhanced treatment technology of algae and its metabolites (smell, algal toxins, etc.) in the water; （3）水处理过程副产物的去除与控制技术； (3) removal and control technology of the by-products of water treatment process; （4）常规水处理的强化技术； (4) enhanced technology of conventional water treatment; （5）高效消毒技术等。 (5) high efficiency disinfection technology, etc. 饮用水中微量有机污染物对人体危害大，但难于去除。特别是高稳定性的溶解性有机污染物，如卤代有机物、硝基化合物、多环芳烃等，对人体危害较大。传统给工艺对这些有机微污染物的去除效果有限，迫切需要研究开发经济高效的微污染物去除技术。 Trace organic pollutants in drinking water are harmful to human body, but difficult to remove. Especially the high stability of dissolved organic pollutants, such as halogenated organic compounds, nitro compounds, polycyclic aromatic hydrocarbons, etc., are more harmful to human body. The traditional technology has limited effect on the removal of these organic micropollutants, and it is urgent to study the development of efficient micro-pollutant removal technology.
