摘　　要：通过对县级城市蔬菜垃圾现状的分析发现,蔬菜垃圾大量无秩序排放给城市居民的生活造成了很大影响,同时产生了较为严重的环境污染问题。针对蔬菜垃圾传统处理方式成本高、经济性低、容易引起二次污染的情况,采用国内先进的“预处理+厌氧发酵+沼气提纯+好氧堆肥+污水净化+大棚气肥”工艺技术,实现资源的微循环利用。工程实际应用表明,该技术路线具有跨区域复制性、前瞻性、代表性。Through the analysis of the current status of vegetable waste in county-level cities,it can be seen that the large-scale and disorderly discharge of vegetable waste has a great impact on the lives of urban residents,besides,it has caused more serious environmental pollution problems.In view of the high cost,low economy,and the possibility of secondary pollution caused by traditional vegetable waste treatment methods,the domestic advanced technology of"pretreatment+anaerobic fermentation+biogas purification+aerobic composting+sewage purification+greenhouse gas fertilizer"can be applied to achieve micro-recycling of resources.The practical application of the project shows that the technical route has cross-regional replicability,foresight and representativeness.
