摘　　要：污水成分复杂,会对不同材料产生不同腐蚀和结垢,影响污水热能技术的应用推广。为验证污水对不锈钢的腐蚀、结垢作用,结合不锈钢的腐蚀机理,设计不同流速的城市生活污水对不锈钢片影响实验,并应用数码相机观察、扫描电子显微镜的能谱分析等方法,观察不锈钢片表面变化情况,以及表面污垢成分,证明了贵阳地区的生活污水对不锈钢的腐蚀、结垢作用较小。不锈钢是贵阳及高原喀斯特地区污水热能应用热交换器材质的良好选择。There is complex composition of sewage,would bring out different corrosion and scaling in different materials,obstructed to promoting the use of sewage heat.To verifying the effects of sewage on the stainless steel corrosion and scaling,combined corrosion mechanism of stainless steel,designed experiment of Guiyang urban sewage influenced the stainless steel of different velocity,using the digital camera,SEM and EDX,observed changes in the surface of stainless steel,as well as surface dirt composition,we found that it is small affect to the stainless steel of sewage in Guiyang.That is a good chance to use the stainless steel to be material of heat exchange of sewage heat pump in plateau karst areas.
