Dry anaerobic system for treating high-concentration organic wastes

Abstract

The invention discloses a dry anaerobic system for treating high-concentration organic wastes. The dry anaerobic system sequentially comprises an anaerobic feeder and an anaerobic inoculator, whereinthe anaerobic inoculator is connected with a plurality of dry anaerobic reactors in parallel or is serially connected with a plurality of dry anaerobic reactors end to end; each dry anaerobic reactorcomprises an anaerobic fermentation chamber; anaerobic feeding hoppers are arranged on the upper parts of the anaerobic fermentation chambers; the other ends of the anaerobic feeding hoppers are sequentially connected with the anaerobic inoculator through pipes; anaerobic discharging devices are arranged on the lower parts of the anaerobic fermentation chambers; the inner walls of the anaerobic fermentation chambers are wound with heating and heat-insulating devices; horizontal plow-shaped stirrers hinged to the two ends of the anaerobic fermentation chambers are arranged inside the anaerobicfermentation chambers; biogas collecting devices are mounted on the outer walls of the other ends of the anaerobic fermentation chambers; each biogas collecting device is connected with a connecting pipe. In a process technology from pollution to recycling, the efficiency of converting organic matters into inorganic matters is improved, the yield of biomass gas is increased, economic benefits areincreased, and the difficulty of difficult elimination in the process of returning a biogas slurry to a field is overcome.

Description

technical field [0001] The invention relates to the technical field of high-concentration organic waste treatment, disposal, source utilization, and in particular to a dry anaerobic system for high-concentration organic waste. Background technique [0002] Anaerobic fermentation technology is the optimal technical route choice for treating high-concentration organic waste pollutants. It has the advantages of high degradation efficiency, low energy consumption, low equipment investment, and many by-products. It has been widely used in agriculture, forestry, animal husbandry and environmental protection industries. After a hundred years of development, anaerobic reactors are also constantly updated according to environmental needs. Under the requirements of current environmental protection policies, resource utilization is more important than harmlessness and reduction. Important, so in order to realize the dream of zero emissions, continuous innovation and breakthroughs in te...
