How to treat the leachate from phosphogypsum?
Thread Content
Phosphoric acid production enterprises generate large amounts of phosphogypsum, which is stored in open piles whether discharged in dry form or wet form. During the rainy season, a significant amount of wastewater is produced, and it is difficult to deal with this waste in a short time, posing environmental risks. Have any enterprises, research institutions, or environmental protection companies carried out any treatment of this leachate? At pH=1, the total P level is between 6000 and 9000 mg/L, fluoride levels are between 600 and 800 mg/L, and ammonia nitrogen levels are 60 mg/L
Why isn’t anyone responding? This is probably a problem faced by many companies
