Recycling of phosphorus-containing calcium salts

Our factory generates 200 tons of phosphorus-containing calcium slag per day, as a result of treating wastewater from organic phosphorus pesticides; the phosphorus content in this slag is over 12% (with P2O5 content exceeding 27%), and the elements present include Ca, C, O, N, P, and Cl. Could it be used as a raw material for producing yellow phosphorus, calcium-magnesium phosphate fertilizer, wet-process phosphoric acid, and hot-process phosphoric acid? Those with experience in this area are welcome to share their opinions, or those interested can get in touch for further discussion.
The key is whether it also contains other organic impurities
What is being produced? Why is the phosphorus content so high? Could you show me the test results? Only then can we determine how to deal with it. Also, what process leads to this production? Is it possible to optimize the processing technique?
The phosphorus pentoxide content in the phosphate, which is used as raw material for producing monoammonium phosphate and diammonium phosphate as well as compound fertilizers, is not this high
