A two-stage anaerobic digester for co-digestion of pig manure and food waste was built according to the schematic diagram shown in Fig. 1. The digester consisted of a 150 L-acid tank and a 250 L- gas fermentation tank. Both tanks were made of cylindrical polyvinylchloride (PVC). The acid tank and fermentation tank were
Jun 3, 2017 · The microbial fermentation bed (MFB) system is considered an effective approach to recycling utilization of agricultural byproducts and pig manure (PM).
Simple Summary. Intensification of pig farming increases the profitability of farms but also leads to greater local environmental pressure from manure nutrient loss. There are various technologies for pig manure processing.
Apr 15, 2020 · The results showed that pig manure and corn straw were suitable for medium temperature fermentation at 30°C, while cow manure and corn straw were suitable for high temperature fermentation at 60°C.
Mar 1, 2014 · Our results showed that under the optimal COD ratio of PM:MAW (1.0:1.5), COD removal and biogas yield were the highest. And in fermentation tanks with different PM to MAW ratios, the structure and composition of bacterial communities varied in the early and late stage.
