Abstract:Based on the study of different effects of function-specialized microbes on the degradation of leachate and stabilization of landfill, a group of complex functional microbes were constructed to accelerate the stabilization of landfill. The complex flora had the greatest influences on the indices of leachate than other combined ones. The three indices including leachate volume, COD and concentration of ammonia nitrogen firstly reached the peak values at the initial stage of landfill then dropped apparently, and the values of three indices kept lower than those of other groups after 49d, 30d and 44d respectively. Moreover, the concentration of ammonia nitrogen reduced to less than 10 mg/L after 130d, which meet the requirements of ammonia nitrogen discharge of leachate according to GB16889-2008. In the whole period of landfill, cumulative volume of leachate, the total mass of COD and ammonia nitrogen were 26.66%,26.59% and 25.40% lower than those of control groups respectively. This indicated that the pollution load of landfill was declined. Moreover, this complex flora also affected the indices of refuse stabilization most greatly. In contrast to the control groups, the concentrations of TOC, TN and C/N of refuse landfill decreased by 39.6%, 18.9% and 25.4% respectively at the end of landfill, while the settlement rate of waste and the biodegradation rate of organics increased by 9.99% and 26.23% respectively.
