The application discloses a kind of gas pollution source detection traceability system, it is related to gas pollution source instantaneous discharge traceability detection technical field;The present application determines target position by extracting the abnormal position in traceability signal, determines the detection route with target position as starting point, matches unmanned aerial vehicle for each route to collect pollutant concentration and collect environmental data, then the compensation amount is corrected pollutant concentration by matching collected environmental data, concentration distribution map is constructed and diffusion main shaft and diffusion time are determined, and the distance of emission source is calculated to lock the suspected position, finally, the real pollution source is obtained by verifying the suspected source through CFD model;In the technical scheme, the pollution area can be covered without dead angle by multi-unmanned aerial vehicle and other angle partition detection, and the concentration data is ensured to be complete and continuous;CFD model verification greatly improves the positioning accuracy of pollution source, shortens the response time of traceability in the instantaneous discharge scene, reduces the positioning error, provides key technical support for rapid disposal of leakage and reduction of pollution diffusion.

Flexible sealing strips are symmetrically arranged between any two adjacent supporting strips, the sides, away from the supporting strips, of the two symmetrically-arranged flexible sealing strips abut against each other, and at the moment, the functions of preventing peculiar smell from overflowing, preventing mosquitoes from flying out and preventing fallen leaves from falling into the well lid are achieved; when water drainage needs to be achieved, water can leak along the gap between the two flexible sealing strips, the more the water amount gathered between the two supporting strips is, the higher the pressure of the water on the arc-shaped parts of the two flexible sealing strips is, the larger the gap generated between the two flexible sealing strips is, and therefore the higher the water leakage speed is; and meanwhile, due to the arrangement of the guide inclined planes of the bevel rubber blocks, the fallen leaves are not prone to being accumulated in the included angles formed between the well base and the ends of the two supporting strips in the sweeping-out process, and the fallen leaves between the two adjacent supporting strips and the two symmetrically-arranged flexible sealing strips can be conveniently guided to be swept out of the well base.
