摘　　要：小型简易垃圾填埋场的填埋量较小,项目通过场地调查后明确采用“开挖筛分+轻质物外运焚烧+腐殖土回填”的主要处理工艺,彻底整治污染并释放土地资源。开挖筛分过程中的筛分规模和工期主要取决于后端焚烧厂接收筛上轻质可燃物的能力,可回收物的存储空间依据其在垃圾中的比例和清运频次进行确认,晾晒场地空间按照存储3 d垃圾开挖量布置,筛分车间的大小根据筛分规模来确定。垃圾开挖区域控制在1000 m^(2),采用分步(层)和接力开挖法进行施工。晾晒后的垃圾含水率降低至30%~40%,采用多级高效垃圾综合分选设备分选并分类处理,场地治理完毕后还需对开挖区域进行治理后评估和跟踪监测,保障场地的最终利用。The volume of small simple landfill is small.Based on site investigation,the project clearly adopted the main treatment technology of“excavation and screening+light material transport and incineration+humus soil backfilling”to clean up pollution and free up land resources.The screening scale and construction period in the process of waste excavation and screening mainly depend on the ability of the back-end incineration plant to receive the light combustibles on the screen.The storage space of the recyclables is based on their proportion and the frequency of clearing and transportation.The space of the drying site can store the excavated waste for 3 days.The size of the screening workshop is determined according to the screening scale.The waste excavation area was controlled within 1000 m^(2),and the construction was carried out by step-by-step(layer)and relay excavation method.The moisture content of the waste after drying was reduced to 30%-40%,and the multi-stage high-efficiency waste comprehensive sorting equipment was used for sorting and classification.After the completion of site management,post-assessment and follow-up monitoring of the excavation area would be needed to ensure the final utilization of the site.
