摘要
针对我国农村存在的饮用水安全问题,介绍了缓速过滤处理技术的原理、设计参数、施工运行要点和试点示范工程的运行效果;分析了缓速过滤处理技术的技术、成本和管理优势。缓速过滤技术能够有效去除水体中的细菌和病原微生物,具有出水品质高、建造方便、制水成本低、能源消耗低、运行稳定可靠、无需投加任何化学药剂、管理简单等优点。因此,缓速过滤处理技术在我国广大农村具有广阔的应用前景,在农村饮用水安全工程中会被广泛运用。
According to rural drinking water safety problems in China,the mechanisms,design parameters,operation points and demonstration project results of slow sand filter technology were introduced.The advantages of slow sand filter technology in technology,cost and management were analyzed.Slow sand filter has the effectiveness in removing parasites,bacteria and viruses.The advantage of slow sand filter is high water quality,simplicity of construction,low cost of producing drinking water,low energy consumption,stable operation and maintenance,no need for addition of any chemical material and simple management,etc.Therefore,slow sand filter technology has broad application prospects in rural and will be widely used in rural drinking water supply project.
