Pipe corrosion is one of the most important issues responsible to the safety of the water supply system in terms of transportation and distribution.Pipe corrosion is close related with the vital activity of microorganism in the water distribution system.The biofilm formed commonly on the inner wall of water distribution system plays a vital role on the corrosion occurred on the interfaces of aqueous phase/ biofilm and biofilm/pipe substrate.Therefore,to study the dynamics of the corrosion process in combina tion with the structure and composition of the biofilm,and the microbial community structure in the biofilm related micro-environment is a useful way to reveal the pipe corrosion mechanism and develop corrosion protection measures.Herewith,several techniques for characterizing the biofilm related micro-environ ment were introduced,namely laser scanning microscopy,electron microscopy,atomic force microscopy,fourier transform infrared spectroscopy,raman spectroscopy and microelectrode techniques,which were rapidly developed in recent years,were introduced with emphasis on their advantages,disadvantages and application prospect in corrosion study.At last,future research direction for those techniques on pipe corrosion study have also been discussed.
