Screening Functional Strains and Constructing Complex Microbial System for Accelerating Stabilization of Landfill
摘要
Abstract
For accelerating the stabilization of landfill, functional strains were screened and sub -cultured repeatedly with traditional microbiological methods in surroundings. Then the screened strains were grouped and coded from I# to VII# based on the different functions of the strains. The compound flora used to accelerate the stabilization of landfill was constructed by analyzing zymogenic capacities and the effects on stability indices. The results show that the functional strains with stable performance includes 9 cellulose bacteria, 8 COD ( chemical oxygen demand) degrading bacteria, and 7 bioflocculant-producing strains. The functional flora coded VII#, composed of all the above strains, has the greatest abilities of generating enzymes, which can improve the biodegradation of refuse effectively and hence accelerate the stabilization of landfill. Compared with those of the control group, the organic biodegradation rates, HP ( humic acid percentage) , and sedimentation of leachate treated with the flora group coded VII# are increased by 26. 23% , 9. 18% , and 10.01% , respectively.关键词
