NOVELTY - Resourceful treatment of aquaculture wastewater involves subjecting aquaculture wastewater to anaerobic fermentation treatment, performing solid-liquid separation, and collecting the liquid phase to obtain anaerobic fermentation wastewater; adding a magnesium source and an adsorbent to the anaerobic fermentation wastewater for crystallization, separating solid and liquid, and collecting struvite; collecting the liquid phase as waste water after crystallization; performing electrolytic treatment on the crystallized wastewater; the aquaculture wastewater is phosphorus-containing wastewater; adsorbent comprises raw materials as biomass feedstock, graphene oxide and iron source. USE - Method for resourceful treatment of aquaculture wastewater. ADVANTAGE - The method uses the adsorption effect of the adsorbent itself, initially realizing the adsorption of ammonia nitrogen and phosphate radical at the same time of adsorption, magnesium ion in the magnesium source, ammonia nitrogen and phosphate are combined to form struvite to realize the resource of ammonia nitrogen and phosphorus element in the breeding waste water.
