龙岩市易腐垃圾协同处理模式及工程建设方案研究

Research on co-processing model and project construction scheme of perishable garbage in Longyan City

随着生活垃圾分类制度实施方案的发布,垃圾分类工作在全国范围内全面开展。易腐垃圾作为垃圾分类收集的类别之一,主要包括餐厨、厨余和农贸市场垃圾等。我国餐厨垃圾处理已有所进展,而厨余及农贸市场垃圾的处理尚处于起步阶段,成为大多数城市面临的现实问题。易腐垃圾的处理是大多数城市面临的现实问题,文章对易腐垃圾协同处理的技术方案进行了分析,结果表明:厨余垃圾由于产生收集方式、性质组成的差异,无法利用餐厨垃圾预处理设备协同处理,需要建设专用的预处理系统,厌氧发酵阶段可结合工程实际情况选择与餐厨垃圾协同处理或单独建设干式厌氧发酵系统,厌氧发酵产物处理和利用可与餐厨垃圾处理厂协同共享。并结合龙岩市易腐垃圾处理现状及需求,提出了适合龙岩市的易腐垃圾分类收集处理模式及工程建设方案。

With the release of the implementation plan for the classification system of domestic waste, the classification of waste has been fully carried out nationwide. Perishable garbage is one of the categories of garbage collection, including food and kitchen, kitchen waste, and farmers’ market garbage. The processing of food waste in China has progressed, and the disposal of waste in kitchen waste and farmers’ markets is still in its infancy and has become a real problem for most cities. The article analyzes the technical solutions for the co-processing of kitchen waste, farmer’s market garbage, and kitchen-kitchen garbage. Because of the differences in the collection methods and nature of the waste, the kitchen waste can’t be co-processed using the kitchen waste pretreatment equipment. In the pretreatment system, the anaerobic fermentation stage can be combined with the actual situation of the project to select the co-processing of kitchen waste or dry anaerobic fermentation system alone. The anaerobic fermentation product processing and utilization can be shared with the kitchen waste treatment plant. Finally, combined with the current situation and needs of perishable garbage disposal in Longyan City, this paper proposes a model for the collection and disposal of perishable refuse suitable for Longyan City and a project construction plan.
