KR20070041481A - Method and device for deodorization of livestock manure wastewater fermentation and retirement - Google Patents

Abstract

The present invention is a method of deodorizing pig manure during the various processes of the waste manure wastewater, non-discharge, rapid fermentation and composting, and liquid fertilizer production technology system, which uses the chaff as a moisture control device in the waste and excrement processing apparatus containing the previously applied organic matter and hermetic fermenter. And equipment related to the operation of the deodorization tower and complicated deodorization lines due to the development of a new pig manure resource recycling process that greatly reduces the manufacturing, installation, maintenance, and management costs of the deodorization tower by improving the deodorization process. It is a method and device to prevent the entire operation by stopping, reduce the maintenance cost due to expensive filter replacement, and reduce the labor cost of labor. It uses the deodorant extracted from natural plants to absorb the odor generated during the process of recycling manure. By using the chemical reaction of adsorption, it is added when pig manure, swollen rice husk, and complex microorganism ferment. By eliminating the conventional deodorization tower device by enabling the complete deodorization of the active substance, and the introduction of a deodorant for removing the odor in the fertilizer recycling process to induce the above chemical reaction inside the active fermenter, a separate expensive deodorization tower It is a method and device that simplifies the process of recycling livestock manure without the deodorization facility line and discharges the odor generated during the process below the discharge allowance.

The present invention develops a system that can reduce odor gas by chemical reaction by using deodorant during fermentation process without deodorization tower and deodorization line during restocking process of livestock manure, and can greatly reduce facility, maintenance and labor costs. And a method and apparatus for an attribute fermentation and soil and liquid production apparatus system.

Rapid social and economic growth leads to an increase in the amount of waste and diversification of waste properties, which not only deteriorate the environment but also cause mental stress on humans due to odors. Unpleasant odors, or odors, are mainly produced by various human activities. There is a lack of coping with extremely low concentrations of irritating gases including nitrogen and sulfur. In particular, hog farms are increasing due to changes in human diet, but there is a lack of odor prevention measures. Legal measures have been taken to prohibit marine dumping of livestock wastewater, and odors generated during the livestock manure recycling process are difficult to manage under the concentration of odor gas without special deodorizers and deodorization lines. Even if there is an excessive amount of facility and maintenance costs for the deodorizer, However, many problems have arisen, such as the reluctance to establish new livestock manure recycling facilities or the principle of waste disposal, such as reducing livestock manure and reducing feed heads.

In addition, the most important and serious part of the livestock manure recycling process is the odor removal process of the exhaust gas. The development of deodorization towers and deodorization lines has been made through rapid development of technology for a long time, but the facilities for reducing odor are still perfect facilities. The deodorization tower and the deodorization line are operated by investing a large amount of facility cost, and the operating cost and labor cost of the facility increases as the number of years increases. Naturally increasing, the most problems in the livestock manure recycling process has emerged, and a solution to the problem has been required quickly.

The continuous development of new technology through continuous research and development due to odor problems during the recycling process of livestock manure has caused many problems such as deterioration, inefficiency, vulnerability, and increase of maintenance cost of existing deodorization equipment. (3) and the gas discharged from the absorption-type natural fermentation tank (9) is mainly a substance having odor components such as ammonia, hydrogen sulfide, amines and T-HC, so that it can be removed by absorption and adsorption reaction by the deodorant, so For the purpose of removal

The present invention is a system (Syatem) of the waste and excrement treatment device containing organic matter as shown in Figure 1.2 fermentation and swelling chaff, microorganisms, manure fermentation process generated in the recycling process of livestock manure is a water vaporization storage tank (3), Production of the deodorizing tower 22 by the process of being discharged to the atmosphere through the duct 6 and the deodorizing tower 22 in a closed storage tank and fermentation tank, such as absorption natural fermentation tank (9), liquid fermentation tank (13), organic matter storage tank (1). Excessive installation and maintenance costs, timely replacement of the internal filter 48, delays in time, and problems caused by problems with the deodorizing equipment line discharged to the deodorizing tower are emitted above the odor gas and emission allowance. There are many cases where the operation of the process is stopped and restarted after complete repair, which reduces the operation rate of the facility and causes complaints of neighboring residents. Remove the top and deodorization

It is designed to be removed by absorption and adsorption reaction by deodorant for the purpose of removing expensive deodorization tower.

1) R-COOH + NH ₃ → R- ₂ + H ₂ O

2) R-COOH + R'-NH ₂ → R-CONHR '+ H ₂ O

3) R-COOH + N (CH ₃ ) ₃ → R-CON (CH ₃ ) ₃ + H ₂ O

4) R-CHO + H ₂ S → R-COSH ₃

5) R-COH + CH ₃ SH → R-COSH ₂ CH ₃

To make the device react

The deodorant extracted from the natural plant is supplied to the pump 53 from the deodorant tank 52 (Tank: 52 of FIG. 3), and the air line 50 is connected to the deodorant line 51. Fermentation materials such as livestock manure, swollen rice hulls, composite microorganisms, activated carbon, and the like are installed in the water evaporation reservoir 3 and the absorption-type natural fermentation tank 9 by installing a nozzle 47 at the bottom of the water pipe 49 and the filter 48. Deodorant is formed by deodorization method and device that can remove odor gas by chemical reaction of absorption and neutralization during fermentation process.

That is, since the expensive deodorization tower 22 device has to be equipped with a device as shown in FIG. 5, the cost of the facility is enormous, and the above-mentioned formula is applied to the tank 52 in order to solve the crucial problem that the deodorizing gas must be necessarily installed. By reacting the deodorant to the pump 53 is supplied through the deodorant supply line 51, and the water and air line (49) and 50 together with the air line 49, 50 to deodorize the deodorant It is to be

As described above, the present invention excludes the deodorization tower (FIG. 5), which is a deodorization device that requires a high cost among prior patent processes such as waste and excretion treatment methods and devices containing organic matter, in the entire process. It is possible to drastically reduce the facility installation cost, facility maintenance cost, labor cost of deodorization process, and the installation area of facility is also greatly reduced. In order to achieve high quality organic fertilizers and liquid fertilizers while realizing zero discharge, no odor and no aversion of high-quality organic-free odorous substances while realizing zero pollution, no odor and no aversion of pollution-free odorous substances, Using high quality organic fertilizer can contribute to preventing acidification of soil, and livestock farm Stand to present a simple method of processing animal manure salrineunde the global environment, there is a critical effect.
