Recovery and Utilization of Fluorine-containing Waste water from Phosphorus Chemical Industry
The fluoride of phosphorus chemical industry is one of its main pollutants.A lot of pollutants containing phosphorus and fluorine have been discharged in the phosphate fertilizer production.Because of their great harmfulness,people pay more and more attention to phosphorus and fluorine pollution recycling.In the paper,the fluorine containing wastewater from phosphorus chemical industry was treated,and high-quality aluminum fluoride was prepared,and the fluorine content in the waste water met the discharge requirement.Under the optimum conditions,1.72 g of aluminium fluoride was obtained from 1 L waste liquid,and the recovery rate of fluorine in waste liquid reached 93%.
