【摘要】 城市生活饮用水水质问题是一个直接影响人民群众生活和身心健康的重要问题。本文对水质问题的发展历程及国内外饮用水水质标准作了简要介绍，分析了国内管道直饮水的现状，提出了管道直饮水水质标准，重点研究了管道直饮水的处理工艺及消毒方法的优缺点，分别以泉水和城市自来水作为原水，通过生产性试验确定了用于管道直饮水净化的较优化工艺——活性炭吸附+反渗透+臭氧消毒。 试验表明：活性炭吸附和反渗透对水中浊度、色度、高锰酸钾耗氧量，细菌总数等有较好的去除效果，臭氧在保持高的杀菌率的同时，可提高出水PH值，出水符合国家《饮用净水水质标准》（CJ94-1999）。另外，试验对循环回流量的确定作了有益的尝试，对试验过程中发现的问题和现象作了分析与阐述。 本研究为管道直饮水处理工艺的选择提供了有力的实验依据和基础，对管道直饮水工程的运行有积极的指导意义。更多还原

【Abstract】 Drinking water plays an important role in people抯 everyday life. In this paper, the development of water quality and standards for drinking water used home and abroad was briefly introduced, and the standards for good quality drinking water has been suggested. The emphasis was placed on the advantages and disadvantages of the purification processes and disinfection methods applied in potable water treatment. Based on the productive tests of good quality drinking water using spring water and tap water as source water respectively, a more applicable and economical purification process, which consists of GAC (Granular Active Carbon) adsorption, reverse osmosis, and ozone disinfection, has been suggested. These tests indicated this process effective in removing turbidity, color, MJI, total bacteria, and so on. Ozone can not only raise PH of the effluent, but also keep it meeting the requirement of the ~Water Quality Standards for Fine Drinking Water?(CJ94-1999). In addition, the cycle discharge was attempted to determine and the problems emerging in the tests was discussed. This study supplies strong foundation for practice and can direct the operation of good quality drinking water treatment.更多还原
