西藏高寒地区森布日水厂设计

Design of Senburi water treatment plant in alpine region of Tibet

为总结西藏高寒地区特殊环境下水厂设计的特点和经验,以西藏山南地区贡嘎县森布日水厂为例,分析和总结了西藏高寒地区水厂设计中面临的取水形式、水处理工艺、结构防冻保温设计等关键问题。结合当地水文地质条件,水厂取水采用管井方案,管井设计需要重点解决沉降和泥沙淤积问题,可通过采用复合保温层等措施解决结构防冻保温问题。

In order to summarize the characteristics and experience of water treatment plant design in alpine region of Tibet,this paper analyzed and summarized the key issues in the design of Senburi water treatment plant in Gong⁃ga County,Shannan Region of Tibet,including water intake way,water treatment process,structural anti-freeze and thermal insulation design etc.The results showed that:according to local geological and hydrological condition,the water intake generally adopts tube well scheme,and sediment settlement and deposition are the key issues to be solved in the design of tube well.Composite insulation layer can be used to solve the problem of structural antifreezing and thermal insulation.
