Decompress visualizer.
Background technology
With the fast development of China's Urbanization Construction and sharply increasing for urban population, the phenomenon of " garbage-surrounded city " is general
All over appearance.In view of the existing trash processing way in China based on sanitary landfills, therefore conventional garbage processing method is ground
Study carefully and show, the solid waste after closing, because of the differential settlement that internal degraded induces, internal air-liquid collection system rupture is special
It is not being continuously increased with landfill body volume, it is possible to serious environmental geological Hazard can be induced, occupying safety to people causes directly
Connect threat.
With the increase of rubbish from cooking proportion in solid waste, degraded produces percolate, landfill gas etc. all can two
Secondary utilization, therefore the refuse soil after closing just becomes an available biomass energy body.Refuse soil after closing
It is substantially carried out following biology, chemistry and mechanical behavior：Biochemical degradation, sedimentation and deformation, the deformation of creep, skeleton structure and solid-liquid-gas
Dynamic evolution.The percolate that resourcebility caused by degraded utilizes contains plurality of heavy metal, if being not added with management and control to percolate,
