The method of the present invention relates to a method for manufacturing color pellets using shafts including air purification and water quality improvement. .

Recently, meat consumption has been increasing due to changes in the dietary culture. Accordingly, the livestock industry including pigs, chickens, cattle, etc. have been enlarged with the increase of the number of breeding to satisfy the demand.

However, such economic development seriously raises the problem of pollution of living environment which must be overcome in order to realize pleasant and abundant human life.

With the recent development of intensive livestock farming, the annual discharge of domestic manure produced in Korea is about 45 million tons, serving as an enormous fertilizer resource, and on the one hand, as a pollution source of the surrounding environment. Due to concerns about the cause of soil and water pollution, odors and pests caused by discharge, demands and interests on livestock manure treatment and environmental problems are increasing in the surrounding area and society.

As of 2005, the number of pigs raised as a substitute for beef and chicken has reached 8,830,000 heads due to mad cow disease and highly pathogenic avian influenza.

However, the number of breeding heads began to decrease after peaking in September 2003, despite the fact that the price of pig farms was high. It is evaluated.

In addition, in accordance with the Enforcement Regulations of the Marine Pollution Prevention Act, organic dumping of organic wastes is scheduled to be banned after 2010, and the difficulties of livestock farms are expected to increase even further, as marine discharge becomes increasingly difficult. This was also reflected in the 2003 Management Survey conducted by the Swine Association. The survey found that the biggest difficulties of the swine workers were in the order of manure treatment, difficulty financing, poor balance of payment, and protection. The priority of the project was investigated in order of resource manure recycling, odor prevention measures and disease prevention.

On the other hand, livestock manure such as cattle manure and livestock manure have been managed mainly in the context of "water and sewage and livestock wastewater law", mainly on the treatment of water quality including purification treatment and the reclamation of individual farm units. Efforts are being made to develop various eco-friendly technologies for the purification treatment of components and the complaints caused by odor problems in the surroundings.

In Korea, the treatment of livestock manure from cattle barns is usually done by marine discharge, treatment using public facilities, and composting with moisture control materials such as sawdust and rice husk, but there are still many difficulties. .

In other words, livestock manure can contribute to eco-friendly agriculture such as soil improvement (physics, chemistry, biology) in addition to pure fertilizer function, but fertilizer composition is unbalanced, Therefore, it is difficult to make fertilizer resources. Livestock manure is a high concentration organic material, and bad odors are generated during processing and processing, causing nearby residents' complaints. Also, some unsanitary housing management may increase environmental pollution.

Farmers who have difficulty in recycling livestock manure have installed purification facilities, but they often have higher concentrations than ordinary wastewater or wastewater. Therefore, there are technological and economic difficulties, and there are increasing cases of improper disposal by farmers' to be.

In the case of public facilities, the throughput is less than the capacity of the facility ('03, operation rate 64.5%), and the treatment efficiency decreases due to the inflow of mixed manure at high concentration and aging due to premature corrosion of the facility, and the collection of manure from small farms The system is inadequate.

Moreover, the installation of public treatment facilities is also perceived as hateful facilities, and there are cases where delays are caused by opposition to local residents and passive promotion of local governments. The rise and the supply and demand, the premature aging of facilities and equipment, the self-processing capacity beyond the number of heads, and the most important problem is that the natural circulation system is not well activated by linking farms and livestock farms. .

In addition, even in farms that depended on marine discharge for manure for various reasons such as disposal cost or effort, the government is considering the waste discharge reduction policy by the government in accordance with the international agreement on waste discharge. If so, there is an urgent need for the development of economical and environmentally friendly technologies for the treatment of livestock manure from livestock houses.

As part of measures to solve this problem, the government has expanded the method of treating organic wastes such as incineration, composting, solidification or solidification, carbonization, and cement kiln, establishing new resource processing facilities (liquid and compost production), and establishing integrated regional management centers. However, despite these measures, frequent complaints due to bad smells have made it difficult to expand livestock farms or processing facilities.

Recently, a technique of using livestock manure such as manure and drying it in a drying furnace and then using it in various ways has been disclosed, but in this case, there is a problem in that a lot of energy is required to dry the livestock powder having a high water content.

In other words, after the heating wire is installed inside the drying furnace, a technique for passing livestock manure into the drying furnace to dry the livestock manure has been proposed, but in this case, there is a problem in that the amount of electricity consumption increases. Even when using fossil fuel, there was a problem that costs a lot.

In addition, various drying methods have been proposed, but it is difficult to dry livestock manure because it takes a lot of time and energy to dry livestock manure with high water content.

The present invention has been invented to solve the above problems, it can be pelletized by compression molding to use livestock manure as a fuel, the production of color pellets using shaft powder to purify the air and water in the manufacturing process To provide a method.

In order to solve the above problems, the present invention comprises: a shaft stocking step of storing stocks in stock; A stirring step of stirring the stored constituents in the reservoir; An air purifying step of purifying the air in the slurry storage by removing lime and nitrogen contained in the mixture by adding lime and zeolite to the stirring shaft powder; A separation step of separating the livestock and the wastewater by inputting the livestock to the strainer; A constriction removal step of removing condensates and impurities of the condensate; A water purification step of purifying the water quality by sequentially adding aluminum sulfate and caustic soda to the wastewater generated from the animal feed; A dehydration step of dehydrating the condensate from which the constriction is removed; A primary drying step of drying the dehydrated condensate using far infrared rays; A mixture forming step of mixing at least one of sawdust, rice hull, carbon, or waste wood flour in the primary dried shaft meal; A secondary drying step of naturally drying the mixture; And a pelletizing step of mixing, milling and stirring the adhesive in the dried mixture, and then pelletizing the pellets by compression molding.

In addition, the stirring step is characterized in that the stirring is made through the ultrasonic oscillation and air.

In addition, it is characterized in that the air and water quality is gradually purified by re-injecting the odor and waste water generated from the pulverized powder to the pulverized storage.

According to the present invention for the purpose of resource recycling of the constituents as described above, the constituent fuel mixed with the sawdust using the constituents may be a target of biomass energy as a component of organic matter of Cm (H20) n, and also Since there is almost no sulfur or organic chlorine components, there is little emission of harmful gases such as sulfur dioxide, hydrogen chloride, and dioxin during combustion, and it can be used as a reducing agent in the soil, making it an excellent fuel in terms of energy and environment.
