摘　　要：开发设计了一种模拟输水管道生物膜反应器(SIBR)试验装置,该试验装置通过模拟一定输水条件下的管壁剪切力,实现了对输水管网水力特性的模拟,并获得国家专利。应用SIBR反应器模拟了循环冷却水输水管道中的水力条件,研究了以碳钢作为循环水输水管材时管内壁生物膜生长发育状况,探讨了微生物腐蚀机理,并采用X射线衍射技术对管壁腐蚀产物进行了分析。The Simulate Inpipe Biofilm Reactor （SIBR, PRC Patent）, which was developed through reproducing the shearing strength on the inner wall of transportation pipe under certain hydrodynamic conditions, was proven to be a good modeling for the hydrodynamics in water pipe systems. Based on SIBR, the growth of inpipe biofilms and the process of microbiological erosion in carbon-steel pipes were developed, and the erosion products were analyzed by X-ray diffraction.
