基于真实源项的填埋场甲烷预警与防护距离划定方法

By using drone platforms and data processing technology, the methane leakage source in landfills can be accurately located and quantified, and its diffusion can be dynamically simulated. This solves the problems of source term distortion and static assessment in existing technologies, and achieves high-precision, real-time risk assessment and protection distance delineation, supporting refined management and emergency response.

Abstract

本发明公开基于真实源项的填埋场甲烷预警与防护距离划定方法，属于环境监测与工业安全风险评估领域。本发明方法通过无人机同步获取填埋场甲烷浓度、气象及影像数据，经密度聚类定位甲烷排放热点，用改进质量平衡法量化解算排放速率并做源强有效性判定；将高置信度源项输入三维大气扩散模型，结合实时气象和地形数据动态模拟，通过实测数据构建校正因子场完成模型后验校正；依据自适应调整的爆炸下限阈值动态圈定多级爆炸危险区，结合嗅阈值圈定恶臭影响区并触发分级预警；最终输出精准安全管控指令和非圆形柔性卫生防护距离方案。本发明实现了甲烷风险的高精度动态评估，提升了防护距离划定的精细化程度。
