| Abstract: |
| The biogas slurry produced by large-scale farms is bulky and concentrated, with low nutrient content and may contain antibiotic residues. Improper handing can easily result in environmental pollution. Membrane separation technology can separate and remove pollutants efficiently and is easy to operate; therefore, the process has attracted wide attention. This paper summarizes and analyzes the membrane separation technology applied to biogas slurry of large-scale livestock farms. By comparing and analyzing the removal effects of different membrane separation processes on pollutants such as carbon, nitrogen, phosphorus, and antibiotics in biogas slurry of large farms, the future development trend and key points of membrane separation technology in manure treatment of livestock farms are explored, providing scientific and technological support for the wide application of membrane separation technology in the field of manure treatment and utilization. |
