1、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用循环给水系统，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用食品型不锈钢管和食品型不锈钢，管道采用管卡连接，设备不应有死角，以便于管道和设备清洗。水箱启停泵水位《建筑给水排水设计规范》(GBJ15-87)(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
2、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43Abstract:Inthebuildingfreshpotablewatertakethecityrunningwaterasawatersource。Inthebu
