Abstract

The carbonized plant powder and the purified phosphating slag are used to filter the biogas slurry, and the filtered residue and filtrate are rationally used to solve the environmental pollution caused by the discharge of the biogas slurry and phosphating slag. The three plant powders (corn straw, wheat straw, and poplar wood shavings) were completely carbonized at the same temperature, and poplar sawdust showed the best filtration performance for biogas slurry. The carbonization of poplar sawdust and FePO4 mixed filter material was carried out at different temperatures to form organic filter media and the biogas slurry was filtered. The results of the study show that as the temperature increases, the filtration rate decreases, but the turbidity also decreases, suggesting that the filtration effect is better. The concentration of water-soluble total phosphorus in the filtrate is highest at 150℃ and can be used as a liquid fertilizer.
