Discussion on treatment method of phosphogypsum reservoir leachate
The main pollution factors of the leachate from phosphogypsum reservoir are phosphorus,fluorine and ammonia nitrogen,with a pH of 2-3.Wet-process phosphoric acid production enterprises generally adopt to return it to the production unit to recover the phosphorus and fluorine inside.Due to the large amount of leachate,there is still a large amount of leachate that needs to be treated,posing a serious threat to the surrounding environment.The treatment methods adopted by domestic wet-process phosphoric acid production enterprises for the leachate from phosphogypsum reservoir are summarized;The advantages and disadvantages of these methods are analyzed,and suggestions for future research directions are provided.
