| Abstract: | For the study of trace elements on the anaerobic dry fermentation biogas production effect, Plackett-Burman test was adopted to optimize the selection of 7 kinds of trace elements, with gas effects as the index to select factors which have important effect on gas production. The test results show that the trace elements have obvious promoting effect on the fermentation of straw anaerobic dry, maximum gas production was 7 922 mL, 76.1%higher than the blank group;significant factors are Ni, Mg, Mo. |
