Hereinafter, a preferred embodiment of a method for treating wastewater free of organic solid waste and an apparatus thereof according to the present invention will be described in detail with reference to the accompanying drawings.

First, referring to FIG. 1, the method for treating wastewater free of organic solid waste of the present invention includes collecting organic solid waste (S101), and crushing and selecting the collected organic solid waste (S103).

The crushing selection step (S103) is a step of crushing the collected organic solid waste to a certain size and selecting various foreign substances contained in the waste.

At this time, the crushing size of the organic solid waste is preferably crushed to a size that is easy to decompose the microorganism, for example, 4 cm or less.

At the time of the selection of foreign matters, foreign matters such as synthetic resins, metals, etc., which are difficult to decompose microorganisms, are selected. Here, the selected vinyl and metals are preferably recycled by transporting them to a recycling and recycling center.

Referring back to FIG. 1, the organic solid waste treatment method of the present invention further includes a preheating step (S105) of preheating the crushed organic solid waste.

Preheating step (S105), by applying heat to the organic solid waste, to prevent the water and oil components and the like contained in the waste is frozen or solidified to solidify.

In addition, by preheating the organic solid waste, the organic waste is in a good state to decompose.

Here, the preheating step (S105), the organic solid waste is preferably put in a separate storage tank and then preheated, wherein the preheating temperature is preferably in the range of 5 ~ 20 ℃.

In some cases, the organic solid waste may be preheated without having to be put into a separate reservoir. For example, it may be preheated by hot air in the process of moving to the next step.

Referring back to FIG. 1, in the organic solid waste treatment method of the present invention, the organic solid waste preheated in advance is introduced into a decomposition treatment tank (S107), and the organic solid waste introduced into the decomposition treatment tank is decomposed into microorganisms (S109).

In the step S107 of disintegrating the treatment tank, it is preferable to use a completely closed decomposition treatment tank. This is to efficiently decompose the organic solid waste in the state of being cut off from the outside as possible.

Decomposition step (S109) is a step of decomposing the organic solid waste of the decomposition treatment tank through the microorganism in the chip (Chip) state. In particular, it enables microorganisms to decompose most organic solid waste without odor. This makes it possible to eliminate a large amount of organic solid waste.

And even if undecomposed organic solid waste residues remain, it is possible to decompose toxic and harmful substances in the residue. Therefore, it is possible to remove various toxic and harmful substances contained in the residue.

In addition, the decomposition step (S109), the microorganism allows the transpiration (蒸散 作用) in the process of decomposing the organic solid waste. Therefore, it is possible to dissipate moisture in the organic solid waste into the air.

This allows the water contained in the organic solid waste to be removed. As a result, the generation of waste water is prevented. Accordingly, there is no generation of waste water, and the generation of waste water prevents environmental pollution due to the waste water.

In particular, by preventing the increase in the internal humidity of the decomposition treatment tank, it is possible to quickly discharge the water generated during the decomposition of the organic solid waste while maintaining the internal environment of the decomposition treatment tank dry state. This prevents the generation of waste water generated during the decomposition of organic solid waste.

The supply of oxygen is a step of injecting oxygen into the decomposition treatment tank to supply a high concentration of oxygen to the microorganisms in the decomposition treatment tank. Therefore, it increases the activity of the microorganisms to enable a vigorous decomposition action. This improves the decomposition treatment efficiency of organic solid waste.

Referring back to FIG. 1, the organic solid waste treatment method of the present invention further includes a step (S113) of stirring and heating the organic solid waste in the process of decomposing the organic solid waste.

Stirring of organic solid wastes causes organic solid wastes and microorganisms to be mixed evenly by mixing organic solid wastes, thereby increasing the decomposition efficiency of organic solid wastes.

In addition, by mixing the organic solid waste and microorganisms evenly, the oxygen in the air can be smoothly supplied to the microorganisms. This further increases the decomposition efficiency of the organic solid waste.

The heating of organic solid wastes makes the organic solid wastes in optimum conditions for the microorganisms to act by applying a constant temperature of heat. Therefore, the activity of microorganisms can be increased to efficiently decompose organic solid waste. As a result, the decomposition efficiency of organic solid waste is maximized.

The collection of organic solid waste residues (S115) is a step of collecting and discharging the remaining organic solid waste residues from the decomposition treatment tank, and the collected organic solid wastes are toxic and water removed, The organic solid waste is produced from dry solids which are harmless to the human body (hereinafter, "organic solid waste" discharged from the decomposition treatment tank is referred to as "dry solid").

The resourceization step S117 is a step of fertilizing or fueling the dry solid. In particular, the dry solids are re-decomposed to fertilize or the dry solids are compression molded into pellets to be used as solid fuels. Therefore, resource recycling is promoted.

Fertilizing or fueling processes of dry solids are already known and detailed description thereof will be omitted.

According to the method for treating wastewater of organic solid waste of the present invention having such a configuration, since organic solid waste is decomposed into microorganisms and water and odors are removed through the transpiration of microorganisms, the amount of organic solid waste is greatly reduced. It can be reduced, and there is an advantage that there is no generation of waste water and odor during the treatment process.

In addition, since the organic solid waste can be treated without the generation of wastewater and odor, it can reduce the concern of environmental pollution due to wastewater and odor.
