Study on the Recycling and Utilization of Fluorine-Containing Wastewater Sludge
The main component of precipitated sludge generated from fluorinated wastewater is calcium fluoride.Currently,the sediment is discharged into the system in the form of mud and transported for disposal.In steel making enterprises,the main component of the daily used flux"fluorite"is calcium fluoride.Therefore,in order to promote the resource utilization of fluoride containing wastewater sludge,the content of calcium fluoride in sludge must reach a certain steel-making reuse standard to meet the requirements of steel-making reuse.Therefore,through the transformation of the original system,on the premise of ensuring the up-to-standard discharge of wastewater,calcium fluoride precipitates that meet the requirements of resource recovery and utilization are obtained.
