Beschreibung
Zusammenfassung:	The invention discloses a comprehensive utilization method of yellow phosphorus slag, which comprises the following steps: adding the yellow phosphorus slag into nitric acid, stirring for reaction, performing centrifugal separation to obtain waste liquid and a white carbon black precursor, washing the white carbon black precursor, drying, calcining, taking out, cooling, and porphyrizing to obtain a white carbon black product; ammonia water and waste liquid are uniformly mixed, solid-liquid separation is performed after full reaction, the obtained liquid is an ammonium nitrate solution, and the nitrogen fertilizer is obtained after concentration and crystallization; solid precipitates obtained through separation are washed, dried, calcined, cooled and ground to obtain a nanoscale composite metal oxide product, the nanoscale composite metal oxide is applied to the field of biomass hydrogen production, and the hydrogen yield is increased; the waste yellow phosphorus slag is used as the main raw material, so that
