| titleOfInvention | Method for treating biogas slurry wastewater by using ferric phosphate powder purified by orange peel and phosphated slag |
| abstract | The invention discloses a method for treating biogas slurry wastewater by using ferric phosphate powder purified by orange peel and phosphated slag. The method comprises the following specific steps: (1) soaking fresh orange peel in water to remove pigment and other soluble substances in the orange peel; (2) drying the soaked orange peel to constant weight; (3) placing the dried orange peel into biogas slurry wastewater, uniformly stirring, and standing for adsorption treatment for 0.5-5 hours; (4) and taking iron phosphate powder purified by the phosphorization residues as a filter medium, filtering the mixed solution after standing, and collecting filtrate to finish the treatment of the biogas slurry wastewater. According to the invention, orange peel and phosphorization residue waste resources are fully utilized, a method of first absorption and then filtration is adopted, and after two times of absorption, the COD content in the biogas slurry is greatly reduced, so that the method has good economic benefits and application prospects. |
