Abstract:

To develop the decentralized water supply systems in a manner appropriate to local conditions usually can solve the problems regarding the safety of drinking water more efficiently in rural areas.Based on expounding the characteristics of cisterns in Northwest China, the effects of influential factors, such as the membrane materials, operation conditions and influent water quality, etc.on membrane flux and membrane pollution, and their mechanisms are analyzed emphatically.At the end, further discussion and analysis are given on economic and technical feasibilities of the application of UF system technique to rural areas and the popularization of UF systems.To conclude, the successful examples of corresponding application are demonstrated.

Key words: cistern, ultrafiltration, membrane pollution

摘要:

因地制宜地开发分散式供水模式,往往能够更加有效地解决我国农村地区的饮用水安全问题.在阐述了西北水窖特点的基础上,作者重点分析了膜材料、操作条件和进水水质等因素对膜通量和膜污染的影响效果和作用机理.最后深入地讨论和分析了超滤膜技术在农村地区应用和推广的经济可行性和技术可行性,同时还介绍了相应的应用实例.
