HIGH EFFICIENCY LIQUID FERTILIZER PRODUCING SYSTEM

摘要

A producing method of a liquid fertilizer is provided to reduce the cost for maintenance of production facilities and to maximize the production efficiency by using additional small-sized fermentation tank and a buffer fermentation tank. The producing method of a liquid fertilizer is performed by a system comprising a small-sized fermentation tank in which liquid urine collected and separated by a collector is aerated intensively, an anaerobic fermentation tank in which the liquid urine passed through the small-sized fermentation tank is fermented under an anaerobic condition, a buffer fermentation tank in which the liquid urine passed through the anaerobic fermentation tank is fermented anaerobically or aerobically, an aerobic fermentation tank in which the liquid urine passed through the buffer fermentation tank is fermented under an aerobic condition to be separated into slurry and liquid fertilizer, and a stabilization tank in which the liquid urine passed through the aerobic fermentation tank is stored.
