摘要
近年来,国家加大对餐厨垃圾处置与资源化基础设施建设的投资力度,推动了餐厨垃圾资源化产业的“减污增效”转型。目前,国内形成以厌氧消化、好氧堆肥为主,生物饲料化、昆虫养殖等为辅的处理技术单元。在实际项目中,单一的技术路径的选择导致餐厨垃圾处理和资源化利用效益低等问题。因此,技术融合和资源化利用模式完善能够充分挖掘并获取餐厨垃圾的资源化价值。基于以上分析,提出了基于水力浆化预处理、三相分离、液相厌氧消化和固相好氧堆肥技术融合、多种资源化技术协同路径,和向能源行业和农业延伸的“环能之道”和“环农之道”相结合的资源化模式。该技术路径和资源化模式的提出对现有项目改造和新项目建设具有重要的指导意义,有利于餐厨垃圾处置与资源化行业的高质量发展。
In recent years,China has increased its investment in the construction of food waste disposal and resource utilization infrastructure to promote the“pollution reduction and efficiency increase”transformation of food waste resourcefulness industry.At present,anaerobic digestion and aerobic composting are as the main treatment technologies,supplemented by biological feederization,insect breeding,etc.In practice,enterprises generally tend to choose a single technical route,which leads to low efficiency and low benefit of resource utilization treatment.Therefore,technology integration and resource utilization model improvement are urgently needed to fully explore and obtain the resource utilization value of food waste.Based on the above analysis,this paper proposed a Bagua Resource Utilization Model based on the integration of hydraulic pulping pretreatment,three-phase separation,liquid-phase anaerobic digestion and solid-phase aerobic composting technologies,and the synergy of various resource utilization technologies to form a combination of“environmental energy road”and“environmental agriculture road”,which closely connects with energy industry and agriculture.The proposed Resource Utilization Model is an important guideline for the renovation of existing projects and the construction of new projects,which is conducive to the high-quality development of the food waste disposal and resource-based industry.
