猪场清粪工艺模式的综合比较分析

Comparative analysis of manure cleaning techniques in pig farms

猪场清粪工艺不仅关系到用水、劳动和舍内环境,更关系到后续粪污的产生、处理和利用。本文通过文献综述和生产调研的方式对不同猪场清粪方式进行分析总结,包括常见的干清粪(人工、平刮、V刮)、水冲粪和水泡粪等,从技术特点、粪污处理效果、应用场景和对新型污染物的影响等方面对不同清粪工艺进行综合比较,并对清粪工艺的研究与应用进行了展望。

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.
