| Abstract: |
| The manure cleaning technique in pig farms not only affects water consumption, labor costs, and the environment in the pig house, but also affects the generation, treatment, and utilization of manure. This study summarizes different pig farm manure cleaning techniques through literature review and investigation, including common dry collection technology, water flushing, and water submerging. Among them, dry collection technology is divided into the manual and mechanical cleaning techniques(V-shaped and flat-shaped). A comprehensive comparison of different manure cleaning techniques was conducted based on technical characteristics, manure treatment effects, and effect on new pollutants, and prospects and suggestions for the research and application of manure cleaning techniques are suggested. |
