摘　　要：针对严寒地区生活排水系统通气管出现霜封现象,采用连续测试某正常使用办公楼生活排水系统通气管的不同管径、不同伸顶高度、不同测试位置时通气管内温度、湿度等参数变化情况,探寻通气管霜封情况形成的影响因素。分析了严寒地区通气管霜封形成的原因,总结了生活排水系统通气管设计管理中应注意的问题,指出了严寒地区生活排水系统通气管霜封现象现状与现行国家标准的矛盾。In view of the frost sealing phenomenon of the vent of sanitary wastewater system in severe-cold regions,the temperature,humidity and other parameters of the vent of sanitary wastewater system in a normally used office building were continuously tested under different pipe diameters,different ceiling heights and different test positions and the influencing factors of the formation of the frost sealing condition of the vent were explored in this paper.The formation reason of frost sealing of the vent of sanitary wastewater system was analyzed.The problems that should be paid attention to in the design and management of the overhang vent of domestic drainage system in severe-cold regions are summarized.The contradiction between the current situation of frost sealing of the vent of sanitary wastewater system and the current national standard is pointed out.
