Method suitable for anaerobic dry fermentation of organic household refuses in fishing villages in Jiaodong peninsular region

Abstract

The invention relates to a method suitable for anaerobic dry fermentation of organic household refuses in fishing villages in Jiaodong peninsular region. The method comprises the following steps: mixing the organic household refuses generated in fishing villages in the peninsular region with sludge in a septic tank and the stored fruit tree leaves, wherein the organic household refuses comprise leftovers, internal organs of aquatic products, fish bones of kitchen wastes, various seafood shells, melon shells, vegetable leaves, tealeaf residues, fish-prawn-crab, outdated items of food and excrements in the breeding industry, adding biogas residues fermented in a normal gas production biogas digester over a month after solid-liquid separation to serve as an inoculum, and performing combined anaerobic fermentation to generate biogas. The limitation of single material fermentation is avoided, the organic household refuses in the fishing villages in the Jiaodong peninsular region and other solid wastes are recycled, and decomposition of the organic household refuses is accelerated by virtue of the sludge in the septic tank and the stored fruit tree leaves, so that biogas production is normally started, fermentation-induced biogas production is promoted, the gas production amount is large, and central gas supply of residents and restaurants in the fishing villages can be realized.
