Embodiment Construction
[0019] Implementation and effect of the present invention are as follows:
[0020] 1) Experimental materials
[0021] Ulva Ulva: salvaged from the sea area of Qingdao City, rinsed with clean water and air-dried. The TS of Ulva kongus was 86.28% and the VS was 72.50% as determined by biogas fermentation.
[0022] Inoculum: Enriched by pig manure in 1999, the Yunnan Provincial Key Laboratory of Rural Energy Engineering of Yunnan Normal University and the Key Laboratory of Advanced Technology and Preparation of Renewable Materials of the Ministry of Education added pig manure for long-term cultivation and preservation. The TS of the inoculum was 8.27% and the VS was 60.85% by biogas fermentation.
[0023] Fermentation device: 1000ml self-made experimental drainage and gas collection fermentation device, the displacement (gas production) has been calibrated.
[0024] Gas analysis instrument: HP4890D type.
[0025] 2) Experimental method
[0026] Using 6 sets of devices, the...
