Description

TECHNICAL FIELD [0001] The present invention relates to an organic waste treatment agent and an organic waste treatment method using the same.

The present invention relates to an organic waste treatment agent and a method for producing an organic waste fuel using the same. More particularly, the present invention relates to an organic waste treatment agent capable of converting an organic waste into a fuel by applying an organic waste treatment agent (or a fuel-forming agent) containing an organic acid, activated carbon and zeolite to an organic waste suspended material in an optimum ratio, ≪ / RTI >

Generally, organic wastes such as food wastes are buried, but recently, foreign substances mixed with food wastes are selected, dried, dried and crushed, and recycled as feed, compost or fuel.

Organic waste (or organic waste desalination liquid) is a high concentration of malignant wastewater containing a large amount of organic matter, carbon dioxide (CO ₂ ), hydrogen sulfide, and ammonia mixed in a large amount and is difficult to purify and has a high purification cost. It was discharged and processed.

However, since the maritime dumping of such wastes is prohibited from 2013 by the London Convention, it is inevitable to dispose of organic wastes that depend on marine dumping and land disposal of wastes. The prospect of business is threatened.

Conventional wastewater treatment methods are microbiological methods. The treatment methods using the microorganisms include hydrolysis, acid fermentation and methane fermentation anaerobic treatment using anaerobic microorganisms. However, since the treatment period is long over 20 days and must be stored for a long time, And it is a disadvantage that the operation condition is complicated. As a fundamental problem, there is a disadvantage that the treatment efficiency of the desolvation solution passed through the anaerobic process is low. In addition, the microbial treatment method has weak weak points against odor generation.

Where there is a sewage treatment plant in the vicinity, biological treatment by activated sludge treatment is reflected in the combined sewage treatment, but since the treatment by the activated sludge treatment should be lowered to 5,000 ppm or less based on the biological oxygen demand (BOD), it usually corresponds to several hundred thousand ppm The pretreatment of a multistage process must be considered.

In order to apply this microorganism method to high concentration wastewater such as organic wastes, it is necessary to reduce the total suspended solids (TSS) to less than 10,000 ppm and to reduce nitrogen, phosphorus and oil contents to a minimum Is required. In this pretreatment process, generally, a method of lowering the total suspended matter mass by using a centrifugal dryer is used, but the centrifugal dryer having such a performance is not only expensive but also removes the oil even if it is dried (or dehydrated) Phase centrifugal dryer capable of separating expensive water, solid and oil from each other is required. However, it is difficult to provide such a high performance centrifugal dryer in domestic organic waste disposal plant. But they are facing the opposition of environmental groups.

The organic matter and the oil content of the organic matter and / or the sludge generated during the drying of the organic waste are high, and when the organic matter and the oil content are heated using the organic matter and the oil content, The fact that this high fuel can be produced has recently become known. At this time, a treating agent capable of removing moisture and various pollutants including various heavy metals contained in the organic waste and reducing the water content and drying (dehydrating) quickly is called " organic waste treating agent (or fuel forming agent) Such an organic waste treatment agent can reduce the moisture content of the organic wastes while removing contaminants such as various heavy metals, and can speed up drying (dehydration), thereby improving the heating value and improving the performance as a fuel. (Or a fuel-forming agent) for the purpose of easily forming such a suspended solid material from an organic solvent.

On the other hand, in the case of fueling such organic wastes, a low water content is required together with a calorific value of 3,000 Kcal / kg or more. Korean Patent Publication No. KR 2013-0058241 discloses a method of manufacturing fuel by reducing the water content of organic wastes using microwave .

However, the method of reducing the moisture content using microwaves as described above has disadvantages in that it is difficult to apply to the conversion of organic wastes into fuel because the drying cost and the facility cost are excessively generated, and thus the resin waste is incompatible.

Humic acid and fulvic acid, which are organic acids, are known to have a strong ion exchange function to easily remove various heavy metal ions and odors contained in soil and the like. These humic acids and fulvic acids are superior to zeolites used as soil amendments, and have excellent cation exchange capacity. In addition to zeolite, which has a toxic ion such as sodium or aluminum in the layered structure, The complex can be formed by adsorption or irreversible oxidation-reduction reaction to form a complex which is harmless and can be removed in a short time, and can be easily converted into a form capable of biodegradation.

In one embodiment, the drying may be performed by stirring the formed reaction product in a drying bath for 10 to 30 hours to form a dried product. During the stirring for the time, the organic acid, the activated carbon, and the zeolite component of the organic waste disposal agent can remove the contaminants from the adsorbent and remove the moisture, and can rapidly dry the moisture contained in the reactants.
