摘要

The present invention relates to a process for the separation of sludge of phosphate in a fraction rich in metal elements (lees powder) and the other in phosphate (alkaline solution of phosphate)With further application of sludge powder (with Fe.Zn and Mn) in the treatment of wastewater by advanced oxidation process in joint performance of various catalysts and alkaline solution of phosphate for the treatment of wastewater with nitrogen amoniacAl by the precipitation of estruvita (fertilizer in potential).
