landfill
The nitrogen removal mechanism was studied and analyzed when treating the ammonium-rich landfill leachate by a set of sequencing batch biofilm reactors (SBBRs), which was designed independently.
      
Performance of landfill leachate treatment system with disc-tube reverse osmosis units
      
Reverse osmosis system with the disc-tube module (DT-RO) was applied to treat landfill leachate on full scale at the Changshengqiao Sanitary Landfill, Chongqing City, China.
      
Methane oxidation in the cover soil of the Khmet'evo municipal landfill in Moscow oblast was investigated.
      
Methane emission from the experimental site of the landfill was highly heterogeneous.
      
Methods for estimation of the methane-oxidizing activity in the cover soil of the landfill were tested.
      
The rate of methane oxidation in the soil correlated with the cell number of culturable methanotrophic bacteria and was the factor limiting methane emission from the surface of the landfill.
      
Seismic stability and permanent displacement of landfill along liners
      
The three-part wedge limit equilibrium method for seismic stability analysis of the landfill along liners is presented.
      
Parametric studies show that the interface strength of liners, the shear strength of waste and the height of retaining wall can influence the seismic stability of landfill along liners.
      
The one-dimensional (1D) equivalent linear dynamic response analysis is used to calculate the horizontal equivalent seismic coefficient-time history of the sliding landfill during earthquake.
      
The seismic permanent displacement of the landfill along liners with different site conditons and heights is evaluated by the Newmark method.
      
The catculated results show that ratio of ky/kmax, site conditions, the amplitude and frequency content of the bedrock motion can affect the seismic permanent displacement of the landfill along liners in some degree.
      
Finally, the seismic stability and permanent displacements of three expanded configurations of a certain landfill case are analyzed.
      
This sharp connectivity needs to be smoothed out after the linear programming solution is found and the earth in the smoothed portion of the roadway has to be moved to the landfill.
      
Landfill sites are always set up in mountain valley, on plain or beside seashore.
      
A complete landfill consists of base system, cover system, and leachate collection and gas extraction system.
      
Geotechnical behavior of the MSW in Tianziling landfill
      
The valley shaped Tianziling landfill of Hangzhou in China built in 1991 to dispose of municipal solid waste (MSW) was designed for a service life of 13 years.
      
Combined treatment of landfill leachate with fecal supernatant in sequencing batch reactor
