医院给水系统设计若干问题探讨

Discussion on several problems in design of hospital water supply system

为满足医院建筑对供水安全的要求,对给水系统用水量计算、洁净手术部供水设计、防止水质污染、分质供水、热水供应等问题进行了分析,并结合工程案例提出相应处理措施。结果表明:用水量计算时需计入陪护人员用水,洁净手术部等对供水要求较高的科室,其两路进水形式的选择需充分考虑供水可靠性和经济性,给水系统自市政接入端至供水点均设置防止水质污染的措施,分质供水设计采用集中预处理+分散深度处理的形式更为经济合理,热水系统采用集中和分散相结合的形式所在满足供水需求的同时降低造价和运行成本。本文成果可为医院建筑给排水设计提供一定的借鉴和参考。

In order to meet the requirements of hospital buildings for safe water supply,such problems as water consumption calculation of water supply system,water supply design of clean operation department,prevention of water pollution,water supply by quality and hot water supply are analyzed,and the corresponding treatment measures are put forward in combination with the project case.The results show that the water consumption calculation needs to take into account the water used by the escorts,and the choice of the two-way inflow forms for departments with high requirements for water supply,such as the clean operation department,needs to fully consider the reliability and economy of water supply.The water supply system is set up from the municipal access point to the water supply point to prevent water pollution measures.The design of water supply by quality is more economical and reasonable in the form of centralized pretreatment + decentralized deep treatment.The hot water system adopts a combination of centralized and decentralized forms to meet the demands for water supply while reducing cost of construction and operating costs.The results can provide certain references when designing water supply and drainage in hospital buildings.
