The　expanding　pharmaceutical　industry　generates　a　large　amount　of　waste　salt　(WS)　with　a　complex　composition,　which　is　difficult　to　treat　and　poses　potential　risks　to　the　environment　and　human　health.　Removing　toxic　organic　compounds　has　become　a　bottleneck　issue　that　needs　to　be　addressed.　This　article　presents　a　comprehensive　review　of　traditional　and　emerging　treatment　technologies　based　on　the　sources　and　characteristics　of　WS　from　the　pharmaceutical　industry.　It　also　discusses　the　problems　and　challenges　faced　by　typical　WS　treatment　technologies　and　evaluates　the　application　of　innovative　integrated　processes.　Building　on　this,　a　future　outlook　for　pharmaceutical　WS　treatment　technologies　is　outlined.　This　review　aims　to　assist　scientists　in　enhancing　their　understanding　of　different　technologies　used　for　treating　WS,　thereby　accelerating　the　improvement　of　process　parameters　and　technologies.
