中国车库式厌氧干发酵技术的产业化现状及分析OA
CURRENT SITUATION AND ANALYSIS OF INDUSTRIALIZATION OF GARAGE TYPE ANAEROBIC DRY FERMENTATION TECHNOLOGY IN CHINA
当前国际主流的厌氧干发酵技术中,车库式厌氧干发酵技术具有堆积态进出料、可最大限度减少沼液产生、发酵过程能耗较低的特点,因此在中国已经实现了产业化实践.对几种国际主流的厌氧干发酵技术进行了对比,对中国的车库式厌氧干发酵产业化项目的具体生产建设情况进行了详细阐述,并从发酵原料类型、产品利用方式、运营效果 3 个角度对中国车库式厌氧干发酵产业化项目的运营影响要素进行了分析.分析结果表明:从各产业化项目的运营情况来看,以农业有机废弃物作为发酵原料的产业化项目必须充分论证有机肥料或生物有机肥料的销售市场;若有必要,可以适当延长产业链,打造下游绿色有机果蔬产品基地.以市政有机废弃物作为发酵原料的产业化项目虽然可以正常运营,但由于其产生的沼渣无法进一步实现资源化,大幅增加了项目的运营成本,因此可以考虑将沼渣干化后生产绿化用有机基质,结合市政园林部门进行消纳,这样既可以提高废弃物的资源化利用率,同时也可以减少市政绿化的用肥量,更有利于推动厌氧干发酵技术的发展.
Among the current mainstream anaerobic dry fermentation technologies internationally,garage type anaerobic dry fermentation technology has the characteristics of stacked feed in and out,maximum reduction of biogas slurry production,and low energy consumption during the fermentation process.Therefore,it has been industrialized in China.This paper compares several mainstream anaerobic dry fermentation technologies internationally and elaborates in detail on the specific production and construction of China's garage type anaerobic dry fermentation industrialization project,and analyzed the operational impact factors of China's garage type anaerobic dry fermentation industrialization project from three perspectives:fermentation raw material types,product utilization methods,and operational effects.The analysis results show that,from the perspective of the operation of various industrialization projects,industrialization projects that use agricultural organic waste as fermentation raw materials must fully demonstrate the sales market of organic fertilizers or bio organic fertilizers.If necessary,the industrial chain can be appropriately extended to create a downstream green organic fruit and vegetable product base.The industrialization project using municipal organic waste as fermentation raw material can operate normally,but due to the inability of the generated biogas residue to further achieve resource utilization,it significantly increases the operating costs of the project.Therefore,it is possible to consider drying the biogas residue to produce organic substrates for greening,which can be combined with the municipal landscaping department for consumption.This can not only improve the resource utilization rate of waste,but also reduce the amount of fertilizer used for municipal greening,which is more conducive to promoting the development of anaerobic dry fermentation technology.
