This paper analyzed the source of fluoride in wastewater in Shaoguan Iron & Steel and discussed its treatment solutions.Source treatment or end treatment could be applied to reduce fluoride from wastewater.The source treatment focuses on minimizing fluorine-containing raw materials or optimizing the process flow.The end treatment can reduce fluoride from 200 mg/L to about 10mg/L, and the removal rate is about 95%,by methods of precipitation,adsorption, and ion exchange etc..
