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。
In view of the existing problem of drinking water safety in rural areas in our country, this paper introduces the principle, design parameters, key points of construction operation and operation effect of pilot demonstration projects. The technology, cost and management advantages of slow filtration technology are analyzed. Slow filtration technology can effectively remove bacteria and pathogenic microorganisms in water, with the advantages of high effluent quality, convenient construction, low water cost, low energy consumption, stable and reliable operation, no need to add any chemical and simple management. Therefore, slow filtration technology in rural areas of our country has broad application prospects, will be widely used in rural drinking water safety project.
