本文介绍了欧共体饮用水指令的有关规定,并简述了欧洲15个成员国及瑞士如何实施的这些规定。欧洲各国在水的消毒和配水管网中采用剩余消毒剂方面,各国要求及标准具有很大差别,尽管有几个国家要求供水要全部消毒并保持剩余消毒剂,但某些国家则不要求消毒或保持剩余消毒剂。有些国家采取折中作法,许多国家已经超过了指令的要求。影响一些国家做法的诸多因素中,除了他们水源的水质、气候条件、及水的净化处理程度外,还考虑到消毒副产物及管网条件、运行情况等.本文还介绍了最近通过的新饮用水指令.
This article introduces the relevant provisions of the EC Directive on Drinking-water and outlines these provisions in how the 15 European member states and Switzerland implement it. In European countries, there is a big difference between the requirements and standards of various countries regarding the use of the remaining disinfectants in water disinfection and water distribution networks. Although some countries require all water to be sterilized and the remaining disinfectants, some countries do not require disinfection Or keep the rest of the disinfectant. Some countries have taken a compromise approach, and many countries have already exceeded the requirements of the directive. Among the many factors affecting the practices of some countries, besides the water quality, climatic conditions and the degree of water purification of their water sources, disinfection by-products and pipe network conditions, operation conditions, etc. are also taken into account.This paper also introduces the recent adoption of new drinking Water instruction
