摘要
取水格栅是反渗透海水淡化过程中的重要组成部分,研究其在海水中的腐蚀过程和防腐的方法,对推动反渗透海水淡化技术的提升有重要的指导意义。本文主要介绍了金属的四种腐蚀过程,并分析了其过程中的腐蚀机理和近些年的相关研究,其中重点阐述了生物腐蚀对金属的影响。依据金属的腐蚀过程的研究,分析了目前采用的生物污损控制技术和金属生物厌触的解决方案,讨论了目前存在的问题,并对技术未来的发展方向进行了展望。
Intake screen is important part of seawater reverse osmosis(SWRO)desalination process.Study of screen’s corrosion behavior and anti-corrosive approaches have important guidance for promoting SWRO desalination technology.In this paper,four types of metal corrosion processes are introduced,and the corrosion mechanism and related research in recent years are analyzed,while the influence of biological corrosion on metals is focused on.Based on the study of metal corrosion process,the currently employed biological contamination control techniques and anti-adhesive strategies are discussed together with their drawbacks,and the future prospect is put forward.
