The manure treatment method using the manure treatment system as described above is composed of a manure inflow process (P1), decomposition process (P2), microorganism input process (P3) and discharge process (P4) as shown in FIG.

The manure inflow process (P1) is a process of introducing external manure into the inside of the storage tank using a manure inlet tube, and the introduced manure includes phosphorus and livestock manure, which means a wastewater in a larger sense.

Next, the manure introduced into the reservoir is decomposed (P2).

A stirring step of pulverizing the manure lump into a small size while mixing the oxygen evenly to the manure by the rotational force of the stirring device, that is, the propeller received power of the driving motor floating the manure level of the reservoir.

In addition, in order to further promote the decomposition, the outside air is introduced by the suction fan to supply the inflow air through the through-hole of the width pipe installed in the bottom of the storage tank to increase the oxygen concentration in the stored manure, thereby increasing the decomposition or decay rate. Aeration stage is done.

In another method, a heating step may be performed to increase the temperature of the stored manure by supplying energy from a heat storage device collected by the solar heat collecting plate to a heater installed on one side of the storage tank, thereby increasing the rate of decomposition and decay. The stirring step, the aeration step and the heating step may further increase the decomposition rate by applying one or two or more.

Next to the decomposition process is a microbial input process (P3).

In this process, the odor gas generated during decomposition is decomposed by using microorganisms to suppress the generation of odor, and a method of selecting and decomposing and removing a specific gas from various gases generating odor can be applied.

That is, general microorganisms such as yeast, lactic acid bacteria, etc. cultured in a microorganism incubator are periodically injected into the storage tank under the control of the control unit.The microorganisms thus injected immediately decompose malodorous gas generated during the decomposition of manure to suppress odor generation will be.

In addition, the microorganism incubator is to culture the microorganisms to promote degradation in addition to the above-described microorganisms can be accelerated the decomposition of the manure by mixing the microorganisms or by adding them to the storage tank alone.

Finally, the microbial input process is followed by a discharge process (P4).

The discharge process is because the gas generated during the decay / decomposition of the manure in the storage tank is lighter than the air is collected to the upper layer of the cover of the reservoir, the collected gas is discharged to the outside through the gas discharge pipe or transfer pipe, the decayed manure Sludge is discharged through the sludge discharge pipe.

In particular, in the process of discharging the gas may be a filtering step of completely decomposing the discharged gas, and a methane storage step for collecting and recycling to the living energy.

In the filtering step, the odor gas is decomposed using a filter filled with microorganism-coated fiber yarns, and the filter is formed in one stage and discharged, or formed in multiple stages to repeatedly decompose the odor gas several times. You can do that.

In addition, the methane storage step is to use the methane gas occupies most of the various gases generated during the decomposition of the manure, the generated methane gas is stored in the storage tank through a transfer pipe installed in the upper portion of the use as living energy It is. In addition, excess methane gas exceeding the capacity of the storage tank is transferred to an incinerator installed on one side of the transfer pipe to be incinerated.

In addition, the above-mentioned example is only an example to demonstrate this invention. Therefore, it is obvious that the ordinary skilled in the art to which the present invention pertains uses the partial change with reference to the detailed description.
