Application Test of New and Efficient Fluoride Removal Agent in the Treatment of High Salt Fluoride Wastewater
The recycling process of waste batteries generates a large amount of high salt fluoride wastewater,posing a huge threat to the ecological environment and human health.The test uses a new high-efficiency fluoride removal agent(model NY-Z02)to treat high salt fluoride wastewater and determine the optimal process conditions.The results show that under the optimal process conditions,the reaction temperature is 20℃,the reaction time is 20 min,the amount of fluoride removal agent is 1.2%,the reaction endpoint pH is 7,the fluoride content in the wastewater after fluoride removal is 11.7 mg/L,the fluoride removal rate is 97.71%,the phosphorus content in the wastewater is 8.93 mg/L,and the phosphorus removal rate is 98.94%.After fluoride removal,both fluoride and phosphorus in the wastewater meet the discharge standards,and the test results can provide a theoretical basis for the industrial treatment of high salt fluoride wastewater.
