浅谈我国二次供水污染及防治措施浅谈我国二次供水污染及防治措施 摘要：受城市给水管网压力的限制，我国大多数民用建筑均采纳二次供水方式供水。许多专家学者调查讨论发现二次供水引起的二次污染现象十分严重。本文阐述了我国二次供水现状，分析了水质二次污染的主要原因，并提出了相应的措施来防止二次污染。结果表明：二次供水系统设计选择不合理、二次供水设备和管材的选用不当和二次供水的运行管理欠缺是水质二次污染的主要原因三。采纳合理的二次供水设计系统、选用满足卫生要求的二次供水设备和管材、加强卫生监督管理和定期进行水质检查是防止二次污染的有效措施。 Abstiact: Because of the limitions of water pressure of the water supply network , The majority of our civil adopted systems of secondary water supply. By researched,Many experts and scholars found that the pollutions caused by the secondary water supply is very serious. This paper describes the status of secondary water supply, and analyzes the main reasons of the pollution caused by the secondary water. Then the paper propose the measures to prevent the pollution caused by the secondary water. The results show that three main reasons of the pollution caused by the secondary water supply are choicesing unreasonable system of secondary water supply, seleting improper equipment and pipe of secondary water supply, Lacking operation and managementare. Designing reasonable systems of secondary water supply, selecting the requirements of the equipment and pipes of secondary water supply which meet the health, strengthen supervision and management and checking the water quality regularly are effective measures to prevent the pollutions caused by secondary water. 关键字：二次供水系统 二次污染 变频泵 屋顶水箱 中图分类号：TV 文献标识码： A Key wordsthe system of secondary water supply the pollution caused by secondary water supplyVariable-speed pump roof tank 近年来...
