Description

Organic waste treatment method and apparatus

The present invention relates to an organic waste treatment method and apparatus for treating organic waste such as food waste.

Organic wastes, including food waste, have a high moisture content and require a drying step as a preliminary step for incineration treatment, and due to deterioration of environmental conditions due to the growth of odor caused by decay in the drying step and the growth of pathogenic bacteria. In addition, it is difficult to implement, and even when the organic waste is to be disposed of and disposed of, it is easy to infiltrate and proliferate pathogenic bacteria in the landfill state and is easy to rot, causing diseases and odors, and becoming a pollution source of the surrounding environment. There was a difficulty.

Various treatment methods have been proposed to treat organic wastes that are difficult to landfill and incinerate.

First, there is a simple drying method to reduce the amount of organic waste by evaporating moisture by blowing hot air to the organic waste or heating the organic waste to raise the internal temperature above 70 ℃ to reduce the amount of organic waste.

However, according to the simple drying method described above, in order to dry organic wastes containing a large amount of water, a large amount of energy is required, and pollution of the surrounding environment is not only severe due to the odor generated during the drying process. In case of drying, the viscosity is increased in the gel state, so that an excessive force is applied to the stirring device, causing enormous energy loss and device failure.

Next, there is a fermentation composting method disclosed in Patent Publication No. 96-10805 as shown in FIG. 1A to remove salt and water by fermenting organic waste for a long time under temperature conditions for composting to utilize organic waste.

Looking at the conventional organic waste treatment apparatus as shown in Figure 1a, the organic waste treatment apparatus is an outer cylinder 10, treatment tank 20, stirring blade assembly 30, stirring blade drive motor 40 and hot air supply Apparatus 50, the treatment tank 20 is provided inside the outer cylinder 10, the stirring blade assembly 30 is installed across the treatment tank 20, the stirring The blade drive motor 40 is connected to the stirring blade assembly 30, and the hot air supply device 50 is also connected to the stirring blade assembly 30.

However, according to the above fermentation composting method, it takes a lot of time to compost, it is costly and economical, it is difficult to use because a lot of odor is generated in the fermentation process, with the exhaust gas discharged from the fermentation process There is a problem in that it does not sterilize the outflowing pathogenic bacteria, and also it is not possible to properly adjust the operating state of the device for proper mixing and fermentation in response to the amount of the object to be treated.

Lastly, there is a fermentation drying method disclosed in Patent Publication No. 96-16786 as shown in Fig. 1B which sets the internal temperature higher than the fermentation temperature to realize drying simultaneously with fermentation.

Referring to the conventional organic waste treatment apparatus shown in FIG. 1B, the organic waste treatment apparatus includes an outer cylinder 10 ', a treatment tank 20', a stirring blade assembly 30 ', and a stirring blade driving motor 40'. It consists of a hot air supply device (50 ') and a deodorizer (60'), the treatment tank (20 ') is installed inside the outer cylinder (10'), the stirring blade assembly (30 ') is the treatment It is installed across the tank 20 ', the stirring blade drive motor 40' is connected to the stirring blade assembly 30 ', the hot air supply device 50' is the stirring blade assembly 30 ') And the deodorizer 60' is configured to inject a deodorant into the exhaust gas.

However, in the fermentation and drying method described above, it takes a long time to compost, which is expensive and economical, and a lot of odor is generated and deodorization is not complete, so odor is generated during fermentation, making it difficult to use. In addition, it does not sterilize pathogenic bacteria leaked with the exhaust gas discharged from the fermentation process, and also has a problem in that the operation state of the apparatus cannot be properly adjusted in response to the amount of the object to be treated.

In order to solve the above problems, by providing the organic waste treatment method and apparatus for controlling the extinction conditions according to the weight loss in the organic waste treatment method, by adopting the extinction method can greatly reduce the amount of organic waste, aerobic The fermentation is carried out under the fermentation conditions so that almost no odor is generated during fermentation, and the improved deodorization method is adopted to sterilize and deodorize the exhaust gas.

The organic waste treatment method of the present invention for solving the above problems, by measuring the weight loss of the organic waste according to the activity of the fermentation treatment agent to evaporate the moisture contained in the organic waste, fermentation and decomposition of the organic waste contained in the fermentation agent By identifying the microbial activity, we want to control the microbial activity conditions such as temperature conditions, humidity conditions, exhaust conditions, and stirring speed.

Fermentation treatment agents for fermentation of organic wastes are porous materials commonly used as a medium for microorganisms, and sawdust is mainly used. As fermenting agents, yeast and bacillus having high decomposition ability in order to decompose carbohydrates, proteins and fats are used. (bacillus), nitrosomonas (nitrosomonas), pseudomonas (pseudomonas) or aerobic microorganisms such as (aerobactor) is prepared by combining the anaerobic microorganisms.

Such yeasts and microorganisms reproduce and act when the proper conditions for their activities are achieved, and under adverse conditions, the microorganisms enter into dormancy with the reduction of microorganisms due to the food war between each microorganism and the activity of the microorganisms is stopped. will be.

Therefore, in order to treat organic wastes having different contents of carbohydrates, proteins, fats, etc., it is necessary to set conditions suitable for different stages according to the type of microorganisms that are active. Organic wastes have been treated only under temperature and stirring conditions.

The present invention is to determine the activity and growth state according to the change by measuring the weight of the change of the amount of the organic waste put into the device according to the activity result according to the type of the above-mentioned microorganisms to meet the conditions accordingly We want to dispose of organic waste in a short time.

The present inventors measured the weight change according to the microbial activity using the organic waste treatment apparatus of the present invention having the above-described configuration and action, and detected and analyzed the state of the microorganism by the measured weight change. The same result as 7e was obtained.

7A to 7E indicate the mixture of organic waste and the microbial treatment agent in the ecology with only simple stirring as in the conventional treatment apparatus. When the curve changes with the change in weight, the first step is the microorganism. This is the initial stage of the reactor, the time when microorganisms start contact with organic wastes, which usually does not bring about weight change, and the second stage is fermentation and annihilator. As the activator, the temperature inside the processor rises and gas emissions increase, and the third stage is a time when the weight change decreases as a stabilizer, showing a slight weight change, and the emission of gas decreases with slow weight reduction. When microbial activity decreases It can be seen that.

Therefore, it can be seen that it is necessary to control the operating conditions of the organic waste treatment apparatus according to the conditions of the initial reactor, fermentation annihilator and stabilizer.

In addition, in order to reduce the amount of organic waste in a faster time, the grinding and mixing should be performed smoothly, and the conditions such as temperature and humidity that help the microorganisms be activated at the appropriate time should be adjusted. The microbial activity is mainly performed under aerobic conditions, and in order to sterilize and deodorize the exhaust gas, a purification facility of the exhaust gas is required. Thus, a step of controlling the operation state by measuring the weight to control such various conditions is provided. I would like to.

Hereinafter, a preferred embodiment of the organic waste treatment method according to the present invention will be described with reference to FIG. 2.

First, the configuration of the organic waste treatment method according to the present invention will be described.

The organic waste to be treated is added to a treatment tank, and a treatment agent including microorganisms and sawdust is prepared or added to the treatment tank. At this time, since the treatment agent is not consumed much, it is enough to replenish the amount of consumption once in a while when the treatment agent is put into operation.

Next, the weight of the organic waste contained in the treatment tank is measured, and then the operating state is appropriately adjusted accordingly (operating state adjusting step). That is, since the weight is related to the amount to be treated, the amount to be processed, and the remaining amount, the amount is used to control the operation state in an appropriate state by adjusting the stirring time, the air supply amount and the air exhaust amount.

Subsequently, the organic waste, the treatment agent, and the air are pulverized while the air is supplied for the growth of aerobic microorganisms, and mixed by the mixed layer vortex. The composite laminar vortex is formed by forming a vortex circulating circulation in various directions on the inner side and the outer side when stirring.

Next, the exhaust gas generated during the treatment is brought into contact with hydrogen peroxide and activated carbon to be sterilized and deodorized. Exhaust gases generated during the fermentation process of organic wastes often contain pathogenic bacteria, so if they are not sterilized, there is a risk of bacterial infection through the exhaust gases. This is because there is a risk of contamination.

Then, after the predetermined time elapses, the remaining amount is measured, and if there is a remaining amount, the steps below the operation state adjustment step are repeated, and if there is no remaining amount, the processing ends.

Next, the action according to the organic waste treatment method of the present invention will be described.

The weight of organic waste contained in the treatment tank is measured so that the operating state is appropriately adjusted. That is, since the weight is related to the amount to be treated, the amount to be processed, and the remaining amount, the agitation time, the air supply amount, and the air exhaust amount are adjusted based on this amount, so that the operation state is appropriately adjusted.

Thereafter, the air is supplied to the injected organic waste and the treatment agent, so that the aerobic microorganism grows smoothly as the aerobic microorganism grows smoothly, so that the aerobic microorganism mixes smoothly with the organic waste, thereby achieving extensive aerobic fermentation.

Subsequently, the off-gas generated during the treatment is sterilized and deodorized in contact with hydrogen peroxide and activated carbon. That is, the exhaust gas is sterilized and oxidized and deodorized while reacting with the generator oxygen of hydrogen peroxide while passing through the hydrogen peroxide, and the sterilized and oxidized and deodorized gas is deodorized by adsorbing impurities causing odor while passing through activated carbon again.

After the predetermined time elapses, the remaining amount is measured, and if there is a remaining amount, the steps below the operation state adjusting step are repeated, and if there is no remaining amount, the process ends.

Organic waste treatment apparatus according to the present invention, in order to significantly reduce the amount of organic waste in the above-described object, to provide a control means for controlling the stirring blade assembly and the operating state for generating a pulverization action and the composite stratified vortex, To prevent the occurrence of odors, an air supply device is provided to enable aerobic fermentation treatment, and a deodorizer having a hydrogen peroxide tank and an activated carbon adsorption tank is provided for sterilization and deodorization.

The organic waste treatment apparatus of the present invention according to the above-described constitution and action is adjusted to adjust the conditions in the reactor according to the initial reactor, fermentation annihilator and stabilizer, and thus it is judged that the organic waste of the present invention can be processed faster. In the waste treatment apparatus, put 100kg of food waste consisting of grains and vegetables, which are mainly carbohydrates, fish waste, meat waste, mixed waste consisting of meat and bone, and autophagy waste containing excessive salt. In order to prevent the temperature drop inside the processor by keeping the proper temperature, the speed of the fan was kept at an intermediate state, and the fermentation and annihilator exhausted the exhaust gas at the highest speed while maintaining the proper amount of moisture. In the ballast, the speed of the fan is reduced and the 7A to 7E are also shown to compare the results of the operation by the existing method and the decomposition process by the existing method.

Figure 7a obtained by the above experiment is a graph of the disappearance of cereals and vegetables in the existing simple stirring can hardly see the change in weight up to about 2 hours, the remaining amount is about 32kg by a sudden weight change from 2 hours to 24 hours After 24 hours, almost no weight loss could be confirmed, but the result of controlling the temperature, humidity, and the speed of the exhaust fan by the method of the present invention showed a slight change of 2 kg until the first 2 hours. From the hour to 7 hours, the amount was drastically decreased, and the remaining amount was changed to 26kg. From 7 hours to 13 hours, which can be seen as the same fermentation annihilator, it became slightly slower, but the remaining amount was reduced to about 20kg to represent 5kg. From 13 hours, the speed decreases more slowly. From 17 hours, the weight reaches almost zero, It did not bring anger.

Figure 7b is a graph showing the disappearance of the fish in the existing simple stirring did not bring about the weight change until about 3 hours, the initial reactor, and gradually decreases after 3 hours and then shows a sharp decrease from 4 hours appearing as a fermentation annihilator After 18 hours, the weight was reduced by about 56 kg until the remaining weight was 42 kg, and the decrease was significantly reduced from 18 hours when the ballast appeared. However, in the case of controlling according to the present invention, the initial reactor was significantly reduced and approximately. After about 20 minutes, the fermenter was decayed, and the weight decreased rapidly. After 18 hours of operation, the residual weight was 2 kg.

Figure 7d is a graph showing the disappearance of the mixed waste consisting of meat and bone as an initial reactor with no change in weight up to about 3 hours in the existing simple stirring, showing a weight loss from 3 hours to 20 hours as a fermentation annihilator, approximately 47 kg After 20 hours, the weight decrease was markedly slowed down and entered the ballast.However, when controlled by the method of the present invention, it remained in the initial reactor for approximately 20 minutes and then immediately disappeared. From the 22 hours, when the 98% disappeared while showing a rapid weight loss, the weight loss slowed down. As a result, the weight loss slowed down to 50kg, equivalent to about 50%.

Figure 7e is a graph showing the disappearance of a relatively high salinity of the swelling flow shows the phenomenon of the initial reactor showing a weight loss of about 6kg from the beginning to approximately 16 hours in the existing simple stirring and 20kg of 8 hours from 16 hours to 24 hours It can be seen that the weight reduction, but in the case of the method of the present invention shows a phenomenon that the weight decreases from the beginning, the remaining amount is 77kg in 2 hours, resulting in a weight loss of 33% as an adaptor included in the initial reactor As we entered, the weight loss slowed down to 6 hours, and then after 6 hours, the weight loss decreased rapidly, and the remaining weight decreased to 7 kg until 24 hours, which appeared to be stable, and the change in weight loss slowed down from 24 hours.

As described above, in the graph of extinction of cereals and vegetables shown in FIG. 7A and in the graph of extinction of meat shown in FIG. 7C, the method of the present invention takes 16 hours and 18 hours to process 100 kg of organic waste. In simple stirring, it can be seen that only 65% and 45% are treated at the same time. In the method of the present invention, up to a stable period, more than 97% of organic waste can be treated. It can be seen that the control by the method of the present invention has excellent results in terms of extinction and time.

As described above, by providing the organic waste treatment method and apparatus according to the present invention, it is possible to significantly reduce the amount of organic waste by adopting an extinction method, so that the treatment is carried out under aerobic conditions, almost odor during treatment It prevents it from being generated, adopts the improved deodorization method, sterilizes and deodorizes the exhaust gas, and also enables the proper control of the operation state by utilizing the weight information of the object to be treated.
