摘　　要：近年来,水资源短缺是一个重要的国际问题,人口膨胀与工业活动扩张,导致了废水排放量急剧增加,使得淡水供应面临巨大的挑战。不管是海水淡化还是处理工业废水,脱盐是解决水资源的重要手段。而当溶液中存在一些悬浮物、有机物、固体颗粒、高结垢倾向离子时,为了保证脱盐装置的正常运行,预处理工作是十分必要的途径。本文概述了脱盐预处理的必要性以及常见的预处理工艺原理、应用要点,希望对水资源短缺问题的改善提供一定的参考。In recent years,water scarcity has been an important international issue,with population expansion and industrial expansion leading to a sharp increase in wastewater discharge,posing a huge challenge to freshwater supply.Whether it is seawater desalination or industrial wastewater treatment,desalination is an important means of solving water resources.When there are some suspended solids,organic matter,solid particles,and ions with high scaling tendency in the solution,pretreatment work is a necessary way to ensure the normal operation of the desalination unit.This article outlines the necessity of desalination pretreatment,as well as common pretreatment process principles and application points,hoping to provide some reference for improving the problem of water resource shortage.
