摘　　要：电渗析饮用水的稳定指数＞９．０，其侵蚀度高达０．５９ｍｍ／ａ具有极严重的腐蚀性，是某油田生活供水管网产生“红水”和严重锈蚀的根本原因；水中铁细菌和硫细菌的大量存在则是管道结瘤、堵塞的生物学原因。电渗析淡水经再矿化后，侵蚀度＜０．０５ｍｍ／ａ，不仅可以保护管道，还改变了水型。The stability index I R of desalinated drinking water from electrodialysis process was more than 9.0.Its corrosion rate P reached 0.59 mm/a.This is the main cause of “Red Water” and severe corrosion in network of pipes of water supply in an oil field.A large number of iron bacteria and sulfur bacteria in water are the biological causes of tubercles and block up.But the P becomes less than 0.05 mm/a,when the water is remineralized.It is an effective measurement to control the pipe corrosion and to provide good quality drinking water.
