The utility model relates to an in-situ remediation
system for a refuse landfill, which belongs to the technical field of refuse landfill remediation and comprises a covering layer, a refuse layer is arranged at the bottom of the covering layer, a
discharge layer is arranged at the bottom of the refuse layer, and a remediation component for in-situ remediation is mounted on the outer side of the covering layer. A
nutrition component for supplementing
nutrition is mounted at the top of the covering layer; the
nutrition assembly comprises two conveying pipes which penetrate through and are fixedly connected to the top of the covering layer, a liquid discharging
pipe fixed between the bottom ends of the two conveying pipes, a sampling
pipe which penetrates through and is fixed to the top of the covering layer, a screen
pipe fixed to the bottom end of the sampling pipe, and a sampling
air pump fixedly installed at the top of the covering layer. According to the in-situ remediation
system for the refuse landfill, nutrition can be properly added to microorganisms in the early stage of construction, meanwhile, air can be conveniently extracted, the content and activity of the microorganisms in the
system can be detected, and the time needed for achieving the stable degradation state of the refuse is greatly shortened.
