The present invention relates to a composting device for organic waste using a tunnel-type plastic bag and a composting method using the device, and more particularly, to a storage tank for pretreated organic waste, and to inject the pretreated organic waste into a tunnel-type plastic bag. The present invention relates to a composting apparatus for organic waste using a tunnel-type plastic bag configured to include an input device, a tunnel-type plastic bag in which organic waste is matured, and a storage tank of the aged organic waste, and a composting method using the device.

In recent years, the amount of garbage to be disposed of and disposed of has rapidly increased due to the increase in population and the improvement of living standards, and so far, most of it has been disposed of by landfill. However, with the end of the use of landfills such as Nanjido, the land to be used as landfills is absolutely insufficient, and it will be more difficult to secure landfills in the future. Therefore, there is an urgent need to develop a method for recycling organic waste for the purpose of extending the life of landfills currently secured and recovering the maximum available resources from organic waste such as food waste.

Waste treatment methods include physical methods such as compaction, grinding and screening, chemical methods such as incineration and pyrolysis, and biological methods such as composting and anaerobic digestion. In recent years, all wastes generated by the above methods have been planned to be disposed of by incineration, but this has hindered the implementation of incineration facilities by neighboring residents. In the case of waste incineration, problems such as excessive use of auxiliary materials due to low calorific value and air pollution occur, and the calorific value of the waste is changed by the moisture content and ash content, and especially the high moisture content reduces the calorific value. It also leads to an increase in the amount of exhaust gas.

In recognition of the urgent need for food waste disposal measures, in March 1993, food waste recycling promotion measures were established, and in May 1994, food waste management measures were established to reach local governments. The basic policy is to reduce and source compost from sources, and to build a compostable by-product collection and supply system. Currently, food wastes discharged from homes, restaurants and hotels are collected and used as livestock feed or dehydrated and then disposed of as garbage. Recently, food waste disposal machines for households, medium and large-sized food waste disposal plants used in hotels and restaurants, and large-scale food waste disposal plants for local governments have been installed, and food wastes are processed, recycled or disposed of by drying, fermentation, and composting. .

However, the existing composting process itself does not lead to the natural fermentation of the food itself depending on the plant, which causes various odors, insects, and harmful microorganisms, and it is not suitable for composting even if it is composted at a considerable cost. Inappropriately disposed of or accumulating in such a state, and the input to the farmland is a problem that damages various crops or worsens the soil.

Among the currently developed technologies, Published Patent Publication Nos. 2002-0081161 and Published Patent Publication Nos. 1998-02971 relate to an air agitating food waste treatment apparatus. The food waste generated at home is mainly controlled by air pressure without a separate stirring device. The present invention relates to an air agitating food waste processing apparatus that can be fermented and decomposed efficiently by increasing the activity and proliferation of aerobic microorganisms by stirring and contacting the air. In addition, Korean Patent Laid-Open Publication No. 2001-0087040 intends to reduce a large amount of food waste in a short time by using a vibration generating unit for enhancing the activity of the agitator and microorganisms to enhance contact with air.

As described above, the conventional technology developed up to now uses an air forced injection or agitation method with an emphasis on a method of efficiently supplying 21% of oxygen in the atmosphere as a method of supplying oxygen during growth conditions of aerobic microorganisms. In this case, the oxygen concentration is fixed at 21% to increase the air input. Otherwise, the oxygen supply is not smooth and a local anaerobic zone is formed, which increases the occurrence of odor or decreases the rate of organic matter reduction. There were side effects.

The present invention has been made to solve the problems of the prior art,

An object of the present invention is to inject composting apparatus of organic waste using tunnel-type plastic bag which matures a large volume of organic waste under aerobic conditions at low cost by injecting pretreated organic waste into a tunnel-type vinyl bag with an input device and aging in aerobic state.

Organic waste mixed with food waste, agricultural by-products such as crests, rice hulls, deciduous leaves, sawdust, fishmeal, seaweed dregs, livestock waste, etc. are stored in the organic waste storage tank 110 and then screw-type transfer facility ( 130 is then conveyed to the mill and sorter 120.

The pulverizer and sorter 120 removes foreign substances such as vinyl, glass fragments, and iron pieces present in the organic waste while pulverizing the organic waste. The organic waste from which the foreign substances have been removed is transferred to the dehydrator 210 by the screw type transfer facility 130 again.

The dehydrator 210 is connected to the collection tank 220, the dewatered leachate is stored in the collection tank 220 to process. The dehydrated organic waste is again transferred to the mixer 310 by the screw type transfer facility 130.

In the mixer 310, an auxiliary material such as sawdust, rice hulls, rice hulls, cotyledon, sesame seeds, etc. is added by a transport facility such as a belt conveyor in the auxiliary material storage tank 330 and mixed with organic waste, and the aerobic microbial culture solution Preference is given to adding. The mixture is transferred to and stored in the organic waste pretreatment storage tank 350 by the transfer facility 320.

Specifically, the raw material stored in the organic waste pretreatment storage tank 350 is introduced through the input hopper 410 formed on the upper side. At this time, the discharge portion is reduced when the raw material is added so that the raw material is uniformly fed under constant pressure. The injected raw material is transferred while the raw material is pushed to the other side when the screw is rotated by a power source such as the motor 430.

The transferred raw materials are introduced into the tunnel-type vinyl bag 500 through the discharge hopper 440, and a vinyl bag fixing device 450 for fixing the plastic bag is provided in the discharge hopper 440.

The organic waste such as food waste does not distinguish between agricultural and forest by-products, marine by-products and animal and vegetable residues, phosphorus, livestock and food processing wastes, and is not harmful to plants and soils. It is preferable to grind to a size of 1 to 5 cm.

The dehydration step (S20) transfers the organic waste from which foreign substances have been removed to the dehydrator 210, and stores the dehydrated leachate in the collecting tank 220 to treat the organic waste water content of about 75 to 85%.

The secondary material mixing step (S30) to the dehydrated organic waste is transferred to the mixer 310, the dehydrated organic waste, and then the secondary raw materials such as sawdust, rice hull, rice cakes, crushed ground, sesame seeds, etc. in the secondary raw material storage tank 330 It is a process of mixing with waste. At this time, the fermentation by aerobic microorganisms naturally present in the fermentation process of the organic waste can be made, it is preferable to add aerobic microbial culture to the mixture.

The sawdust, rice husks, crests, etc. are used as a moisture control bar, sawdust is known as a moisture control agent excellent moisture absorption ability and breathability. The chaff has a longer life time than the sawdust, so it has a long lifespan, and the particles are large, which allows the air to communicate well and has a high moisture content. Therefore, if it can exert the function of the moisture control agent is not limited to the subsidiary materials, such as the sawdust, rice hulls, crest, etc., the secondary raw materials are mixed about 5 to 25% by weight relative to the weight of the organic waste.
