规模养猪场粪污无害化处理技术研究与应用

Research and Application of Harmless Treatment Technology of Pig Manure in Large-Scale Pig Farms

本文以江苏省如皋市为例,结合当地气候条件和农业发展现状,采用能源生态型利用模式,开展规模养猪场粪污无害化技术研究与应用,制定前期减排、中期资源开发、后期资源多层次综合利用的技术研究思路,形成新型沼气发酵池型、稳定运行系统、沼气发电并网和沼肥农田利用系统等研发成果,为养猪场粪污治理找到了较理想的途径,具有较高的推广价值。

Taking Rugao City of Jiangsu Province as an example,combining the local climate conditions and the current situation of agricultural development,using the energy ecotype utilization model,the research and application of the harmless technology of pig manure in the large-scale pig farm was carried out in this paper.The technical research ideas of the early emission reduction,the development of the medium resources and the comprehensive utilization of the later resources were proposed.Some research and development results were formed,including a new type of biogas fermentation pool,stable operating system,interconnection of biogas power and grid power,biogas fertilizer system for farmland,etc.Though the results,a better way could be found to control the manure pollution of the pig farm,which has high popularization value.
