EACH SEASONALLY HOGS EXCREMENT DISPOSAL AUTOMATICALLY CIRCULATION USING THE METHOD OF QUICK DISASSEMBLY AND FERMENT SYSTEM

摘要

A natural-circulation seasonal treatment method for swine manure using a method for rapidly decomposing and fermenting swine manure according to the present invention relates to an integrated seasonal treatment method for swine manure by circulating manure through the slurry pit of a pigpen and a main manure treatment plant and by exploiting natural-circulation aeration and fermentation using microorganisms without separating the manure into solid and liquid with a solid-liquid separation tool when treating the manure. The natural-circulation seasonal treatment method for swine manure using a method for rapidly decomposing and fermenting swine manure is characterized in that first and second anaerobic fermentation steps are conducted by replacing approximately a third of the lower slurry water (treated water) in the fermenter of the main manure treatment plant with underground water or general water and by supplementarily inoculating microorganisms in the process of injecting microorganism culture medium through the aeration tank of the main manure treatment plant in winter/spring when a gap in the daily temperature range is 10 to 20, and that a first rapid decomposition/fermentation step is conducted by increasing by within 10 wt% with respect to winter/spring the discharge volume of final treated water discharged from the circulation tank of the main manure treatment plant to the slurry pit in summer/fall when the temperature is above 25 at midday. Accordingly the management of microorganisms is facilitated in spite of seasonal change in temperature, and seasonal treatment efficiencies of manure using microorganisms can be kept constant. Also manure treatment using microorganisms can be facilitated in regions or seasons that a gap in the daily temperature is severe or the temperature is low.
