The present invention relates to an eco-friendly liquid fertilizer manufacturing method for recycling an intentionally killed livestock carcass, which can process-efficiently recycle an artificially, intentionally killed livestock carcass as fertilizer without leaking leachate or producing a foul odor. The eco-friendly liquid fertilizer manufacturing method for recycling an intentionally killed livestock carcass according to the present invention comprises: an intentional killing step of intentionally killing livestock and discharging a livestock carcass; a carcass supplying step of supplying the intentionally killed livestock carcass into a liquid fertilizer reaction tank having a gas emission port formed on an upper side thereof and a perforated pipe disposed therein, and sealing the liquid fertilizer reaction tank; an underground burying and decomposing step of burying the liquid fertilizer reaction tank underground after connecting a deodorizing unit which deodorizes and purifies gas emitted when decomposing the livestock carcass to the gas emission port of the liquid fertilizer reaction tank, and decomposing the livestock carcass for a prescribed period of time; a liquid fertilizer aeration step of connecting a blower to an open end portion of the liquid fertilizer reaction tank to inject air into the liquid fertilizer reaction tank for liquid fertilizer aeration; a liquid fertilizer collection step of connecting a pumping transport pipe of a liquid fertilizer collection vehicle to an open end portion of the perforated pipe of the liquid fertilizer reaction tank after liquid fertilizer aeration to forcibly transport liquid fertilizer in the liquid fertilizer reaction tank to collect the liquid fertilizer; and a bone separation step of digging up the liquid fertilizer reaction tank from underground and then loading bones of the livestock carcass remaining in the liquid fertilizer reaction tank onto a waste collection vehicle to perform a final incineration process. |
