以沼气工程设施改造提升为纽带,因地制宜构建种养结合的新型高效生态循环模式,是实现农业高质量发展的有效途径之一。本文以浙江嘉兴某农业公司三沼(沼液、沼气、沼渣)综合利用工程为例,分析了该公司工程设施存在的问题及原因,探讨“猪—沼—葡”生态循环模式的改造过程,并对其效益进行分析。通过走访调查发现,该公司三沼综合利用工程运行时间较长,管理维护不到位,存在厌氧发酵效率有待提升,沼肥利用设施亟需完善,沼气资源化利用有待加强,猪粪沼渣贮存设施和利用途径有待完善补充,沼肥施用有待进一步规范等情况。具体改造措施包括利用厌氧扩容优化,提升了厌氧发酵效率;采用多级沉淀过滤、氧化塘曝气、葡萄种植消纳、调压供气等工艺结合的方式,完善了沼液后处理、沼液输送、沼气输配等设施;利用混合厌氧等发酵技术,优化了粪污处理工艺;从浸种、基肥、追肥等角度对沼肥施用技术进行规范。通过以上改造,成功构建了“猪—沼—葡”生态循环模式,该模式取得了较好的经济、社会和生态效益,具体包括提升了农产品产量与品质;集成了绿色生产技术,促进农机农艺融合;有效解决了规模养猪场粪便污水的利用问题,保护了生态环境。

Taking the renovation and upgrading of biogas engineering facilities as a link, and building a new type of efficient ecological circular model that combines planting and breeding based on local conditions is one of the effective ways to achieve high quality agricultural development. The comprehensive utilization project of three biogas(marsh liquid, marsh gas, marsh residue) of a certain agricultural company in Jiaxing City, Zhejiang Province was taken as an example, the problems and causes of the company’s engineering facilities were analyzed, the renovation process of the “pig-biogas-grape” ecological circular model was discussed, and its benefits were analyzed. Through field visits and investigations, it was found that due to the long operation time and inadequate management and maintenance of the company’s comprehensive utilization project of three biogas, there were problems such as the need to improve the efficiency of anaerobic fermentation, the need to improve the facilities for the utilization of biogas fertilizer, the need to strengthen the resource utilization of biogas, the need to improve the storage facilities and utilization channels of pig manure and biogas residue, and the need to further standardize the application of biogas fertilizer. Specific renovation measures included through the expansion and optimization of anaerobic fermentation, the efficiency of anaerobic fermentation was improved; by combining multi-stage sedimentation and filtration, oxidation pond aeration, grape planting absorption, and pressure regulation and gas supply, the facilities for biogas liquid post-treatment, biogas liquid transportation, and biogas distribution were improved; by using mixed anaerobic and other fermentation technologies, the process of manure and sewage treatment was optimized; and the application technology of biogas fertilizer was standardized from seed soaking, base fertilizer, and top dressing. Through the above renovations, the “pig-biogas-grape” ecological circular model was successfully constructed. This model has achieved good economic, social and ecological benefits, including increasing the yield and quality of agricultural products; integrating green production technologies and promoting the integration of agricultural machinery and agricultural techniques; effectively solving the utilization problem of manure and sewage from large scale pig farms and protecting the ecological environment.
