Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an organic waste recycling facility,

The present invention relates to an organic waste recycling facility, and more particularly, to an organic waste recycling facility using organic wastes including livestock manure, food wastes, and agricultural and livestock by-products, and using biogas produced in composting, The present invention also relates to a treatment facility that uses organic wastes capable of performing resource recovery while discharging wastewater, such as bio-energy, composting and liquefaction.

Currently, organic wastes such as food waste and livestock manure are increasing due to diversification and upgrading of population growth and dietary level. In particular, as the demand for livestock products increases, the livestock industry is becoming larger in order to meet the demand. Even if the domestic livestock breeding status is examined, the average number of livestock raising livestock is more than several tens to several hundreds. It is well known that it is fully progressed.

Since the type of livestock industry has been enlarged in this way, the amount of livestock manure that is inevitably generated in the livestock industry also becomes a huge amount. In the case of traditional small livestock industry, the method of exhausting the generated livestock manure is used by composting, etc. However, in recent years, the scale of the livestock industry itself has changed, It is natural that this traditional method can not be used. In the case of the conventional method, there was no way to separate various foreign substances, parasites and bacteria contained in the livestock manure, and when these materials were used as compost, these foreign substances, parasites and bacteria were transferred to the crops, . In addition, in the modern living environment, the odor generated in the place where the animal manure is stored before composting is also a big problem.

Therefore, in recent years, there has been a proposal to convert a large amount of animal manure into useful products such as bio-energy, compost, and feed, such as food wastes, without directly composting them. Among these, bioenergy has been found to be superior in terms of environmental and economic efficiency compared with other renewable energy. In advanced Germany, bioenergy generated from organic waste such as food waste and livestock manure, Of the world's total energy consumption is more than 60%. In addition, Korea is also banned in Korea since 2013 because of livestock manure and food waste disposal of domestic wastes in accordance with the London Convention. Therefore, it is appropriate to circulate resources by converting livestock manure into bio-energy.

However, in spite of the necessity and feasibility of this bio-energy conversion of organic wastes including livestock manure and food wastes, there is little research on the appropriate treatment of organic wastes.

At present, as a method of treating the anaerobic digestive juice, which is one type of organic waste, there are proposed water treatment methods and sewage treatment methods, and utilization methods as fertilizer. The water treatment method is disadvantageous in that a large amount of water resources and processing cost are consumed, so that it is preferable to utilize it as fertilizer.

Accordingly, the present applicant has proposed a natural circulating anaerobic digestion solution recycling system through Korean Registered Patent No. 10-1626752 (Registered as "Prior Art 1" below). The above prior art document 1 is a system for recycling an anaerobic digestion liquid that has been subjected to a biogas production process, comprising: a water collecting tank for collecting anaerobic digestive liquid; A solid-liquid separator for separating the solid matter from the liquid manure by receiving the anaerobic digestion liquid from the collection vessel; An oxidation tank for collecting the liquid manure separated from the solid-liquid separator and oxidizing the organic matter of the liquid manure by supplying oxygen to the liquid manure; A dissolved oxygen system for partially introducing the liquid manure stored in the oxidation tank to increase the dissolved oxygen concentration by pure oxygen, and then re-supplying the dissolved manure to the oxidation tank; A liquefying tank which is supplied with liquid manure from the oxidation tank and sequentially passes through a plurality of accommodating portions formed therein, and is fermented by aerobic microorganisms to be liquefied; A liquid storage tank for receiving and storing liquid fermentation completed in the liquid storage tank; A purifier for purifying the purified liquid by removing remaining solid matter and gas by supplying the liquid from the liquid storage tank; A microorganism incubator for supplying the microorganisms to the oxidizing tank and the storage tank by using a microorganism supply line; A blower for supplying oxygen to the oxidation tank and the liquid storage tank storage tank using an aeration line to perform aeration; A first conveyance line for re-supplying a part of the liquid in the liquid storage tank rear end receiving portion to the oxidation tank or the reservoir receiving portion in the liquid storage tank; A second conveyance line for re-supplying a part of the liquid in the liquid storage tank to the oxidizing tank or the reservoir in the liquid storage tank; And a sprinkling line for pouring the liquid manure of the liquid storage tank or removing bubbles from the liquid storage tank by supplying an external constant to the liquid storage tank, wherein the oxidation tank has a vertical partition wall, The first oxidizing unit and the second oxidizing unit are provided with a width mechanism connected to the aeration line so that the aeration is performed, Wherein the dissolved oxygen system is connected to introduce the liquid manure of the first oxidation unit to increase the dissolved oxygen concentration and then to supply the dissolved oxygen to the second oxidation unit. In the prior art 1, the conventional dissolved oxygen system is utilized to increase the dissolved oxygen concentration of the liquid manure in the oxidation tank. Therefore, the specific structure for forming the long channel is not presented, and the treatment for the undissolved oxygen And it is limited only to the treatment of the liquid material which has been subjected to solid-liquid separation in anaerobic digestion liquid, which is a part of the organic waste.

As described above, the organic waste recycling facility 100 of the present invention includes the pretreatment unit 200, the anaerobic treatment unit 300, the liquefaction unit 400, the composting unit 500, the deodorization unit 600, And a gas generator 700.

The pretreatment unit 200 is a step of carrying out various organic wastes to prepare for anaerobic digestion, liquefaction, or composting. In the present invention, organic wastes are classified into representative livestock manure, millet, food waste, agricultural and livestock by-products, and pig iron.

The preprocessing unit 200 measures the weight of the organic waste by measuring the weight of the vehicle by the weighing platform while entering the facility in case of a vehicle carrying livestock manure, barnacle, food waste, agricultural and livestock product, and pig iron. The weighing platform is usually installed at the bottom of the entrance of the facility to measure the load at the time of entry into the vehicle and to measure the weight of the vehicle at the time of departure after the organic waste is introduced, .

Further, after the metering, a process of removing a contamination source adhered to the outer surface of the vehicle is performed through the vehicle tamper-proof unit. The vehicle protector includes a plurality of injection openings for spraying water or a cleaning liquid on both sides of the vehicle, upper and lower directions, and a sidewall and a roof are formed with front and rear sides of the advancing direction opened to prevent the injection liquid from being discharged to the outside. .

In the livestock manure storage tank 210, a plurality of screens are formed to separate and separate contaminants contained in the livestock manure. The screen may be separated from the livestock manure reservoir while the obstacles are separated, or the livestock manure may be loaded into the livestock manure reservoir through the screen when the livestock manure of the vehicle is unloaded.

If the organic waste is food waste, the organic waste is once stored in the food storage tank 220. The food stored in the food storage tank 220 is supplied to a conventional crushing and sorting machine 250 (crushing and sorting machine) to selectively remove contaminants and fibers and crush them to a predetermined size. At this time, the crushing and sorting unit 250 may be installed at the bottom of the food storage tank 220 so that the stored food can be introduced into the hopper of the crushing and sorting machine by the valve interception formed in the discharge unit under the food storage tank. The selected contaminants from the crushing separator 250 and the livestock manure storage tank 210 are stored in a separate contaminant storage tank and then carried out. In the next step of the crushing and screening machine, a fine crusher is additionally installed to crush the primary crushed food waste to a finer size, thereby increasing the efficiency of the anaerobic digestion as a post-process. The food waste transport to the food storage tank, the crushing separator and the fine crusher is lowered by its own gravity or transferred by the transfer pump.
