An experimental installation was built based on the semi-aerobic landfilling theory,in which the concentrations of φ(CH_4),φ(CO_2),and φ(O_2) were determined.The results showed that,after 21 weeks operation,the municipal solid waste was in the stage of methane generation.φ(CH_4),φ(CO_2),and φ(O_2) reached 14.7%,18.6%,and 4.0%,respectively,at 27 weeks.In this installation,oxygen diffused through the pipelines collecting leachate and the vertical gas pipelines,and produced an O_2 depletion zone around these pipelines.According to mathematical analysis,the aerobic zone was defined,on which a contour line of O_2 concentration was fitted.The results indicated that O_2 concentration showed a hyperbola in longitudinal profile and was higher in the upper zone than in the medium and bottom zones.In addition,the oxygen diffusion equation in the horizontal direction was deduced;the radius of oxygen depletion in the horizontal level was 94.2 cm,and was about 23.5 times the radius of the longitudinal gas pipeline.The percentage of O_2 depletion zone in the longitudinal profile was 93.6%.Also,the equation of O_2 depletion zone in the longitudinal direction and in spatial scale was obtained.
