【摘要】 从供水系统柔性化建设出发,提出并设计了一种平危结合的膜法处理工艺和设施制造方法,为应对突然饮用水危机提出一种新思路.工艺方面根据平时直饮水用水需求,建立针对以市政自来水为源水的稳定的膜过滤工艺,保证过滤出水达到饮用净水水质标准(CJ 94—2005);根据危机时刻生活用水基本需求,建立针对危时应急储备水源为原水的"预处理+MF"工艺,保证过滤出水达到生活饮用水标准(GB 5749—2006).设备方面设计平危两用产水设备,使其能够通过合理组装,达到既能满足平时直饮水需求,必要时又能通过加装预处理满足危时生活饮用水需求.以自来水为平时源水,就近提取天津工业大学新校区人工湖水作为危时源水进行实验,结果显示,这种设施达到了平危两用的预期目标.更多还原

【Abstract】 In order to deal with drinking water quality crisis,from the view of flexible construction of water supply system,the paper proposes and designs a membrane water treatment facility which considering the two different needs in flat situations and in risk situation in one package.In technological aspects,according to the needs of the direct drinking water in the normal time,a stable membrane filtration process using municipal water as raw water is established to ensure the filtered water reaches the direct drinking water quality standards(CJ 94—2005).At the same time,according to the basic domestic water needs in crisis times,a"pre-treatment+ MF"process using the contingency reserve source water as raw water is established to ensure the filtered water reaches the filter drinking water standard(GB 5749—2006).In equipment,a dual-use water production equipment is designed which can reach the usual needs of drinking water and the crisis needs of drinking water through the reasonable assembling.Experiments,which takes municipal water as raw water for usual and take manufacture Lake of the new campus of Tianjin University’s water for risk separately,show that the proposed facility realize the design function.更多还原
