摘 要建筑物内的生饮水以城市自来水为水源。建筑物内生饮水系统的供水管网应采纳循环给水系统，管网流速不低于 0.6m/s，以防滋生微生物。回水应进行 0.20μm～0.45μm 的膜过滤及紫外线和臭氧联合消毒，进一步除去管网中杂物和微生物，才能再一次进入供水管网。生饮水的供水管和设备应采纳食品型不锈钢管和食品型不锈钢，管道采纳管卡连接，设备不应有死角，以便于管道和设备清洗。水箱启停泵水位《建筑给水排水设计法律规范》(GBJ 15-87)(以下简称《建水规》)，有关水箱的设计为第2.8.1 条至 2.8.5 条，但并没有规定屋顶水箱的启停泵水位。致使水箱出现了调节容积太少，有时在最大秒流量时供水不足。建筑物排水立管和地漏的设置，对室内卫生水平特别是卫生间的空气质量起着决定性的作用。目前国内《建水规》中排水立管的设置要求主要是依据排水量来决定的，没有引入室内卫生质量等级这一设计参数。建筑物尽管等级很高，但卫生间仍为单立管排水，致使臭味不断，很不相称。关键词: 建筑 给水 排水 水箱 消防Abstract :In the building fresh potable water take the city running water as a water source 。 In the building lives the potable water system the water supply pipe network to be supposed to use the circulation to give the aqueous system, the pipe network speed of flow is not lower than 0.6m/s, guards against multiplies the microorganism 。 The backwater should carry on 0.20μm~0.45μm the membrane filters and the ultraviolet ray and the ozone union disinfection, further except the pipe network in the sundry goods and the microorganism, can again enter the water supply 。 Lives the potable water the delivery pipe and the equipment should use the food stainless steel pipe and food stainless steel, the pipeline uses the tube card connection, the equipment should not have the dead angle, is advantageous for the pipeline and the equipment clean.
