It is an object of the present invention to provide a method for treating malodor of kitchen waste and a structure of a filter for deodorizing kitchen waste.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the method of treating odor of kitchen waste and the structure of the filter for deodorizing odor of kitchen waste according to the present invention will be described in detail. Home waste, grocery store, cafeteria, food processing plant, etc. For example, a large amount of kitchen waste such as vegetable waste, fish waste and meat waste is generated. These kitchen wastes are temporarily stored in an indoor garbage container or garbage dump, and are disposed of when they become full. If these kitchen wastes are left for a while, they will start to rot due to the propagation of microorganisms and generate odors, so that they must be disposed of early. Therefore, when the components generating these odors were investigated, vegetable wastes contained 90% to 95% of water and were not easily decomposed by microorganisms and did not generate odors. However, in the case of kitchen waste composed of fish waste, meat waste, and the like, and processed food waste, the water content is 55% to 65%.
%, It becomes easily susceptible to decomposition by microorganisms, and if left for one day, bad odor due to putrefaction starts to be generated.
The origin of these bad smells is particularly conspicuous when lactic acid bacteria in microorganisms multiply, and when garbage waste is acidic and the water content is 55% to 65%, the growth of lactic acid bacteria becomes active. It is known. In addition, kitchen waste such as fish chips and meat chips with a carbon / nitrogen ratio of 20 or less and a water content in the range of 55% to 65% will be rapidly decomposed by microorganisms, and will quickly rot and produce an odor. become. However, kitchen waste having a carbon / nitrogen ratio of 20 or more, such as cooked rice and squid, is not easily decomposed. These foods are often mixed, but it is almost impossible to separate them.
Therefore, the inventor of the present application can suppress the decomposition reaction of microorganisms even in the case of kitchen waste in which food wastes of various conditions are mixed, by adjusting the water contained in the kitchen waste to 40% or less. Paying attention to this, kitchen waste is left, for example, in a drying room or put into a container with a drying device and subjected to drying treatment, and the water content is adjusted to be 40% or less, and the decomposition reaction of microorganisms is performed. This is to suppress it. As an alternative to the above method, even when the pH of kitchen waste is adjusted to 7 or more, it has an effect of suppressing the decomposition reaction of kitchen waste by microorganisms, and particularly suppresses the growth of lactic acid bacteria having a strong putrefaction smell. It has been found to control odors. Therefore, calcium silicate, lime or the like is added to the kitchen waste to about 0.02 to the kitchen waste 1, thereby adjusting the pH of the kitchen waste and suppressing the decomposition reaction of microorganisms. Even when the above two methods are performed separately, the growth of the decomposition reaction of the microorganisms can be suppressed and the odor can be prevented, but when the storage time of the kitchen waste is further extended or the effect of suppressing the decomposition reaction by the microorganisms is further reduced. If you want to increase the water content of the two methods above, namely the kitchen waste 4
By combining the method of reducing the concentration to 0% or less and the method of adding calcium silicate or lime to increase the pH to 7 or more, an effect of further suppressing the decomposition reaction of kitchen waste by microorganisms can be obtained.

The above description has been made of means for preventing the generation of offensive odors generated from kitchen waste accumulated in the room and filling the room. However, if the odor filled in the room is exhausted to the outside as it is, it may cause trouble to neighboring private houses. It is clear that it has
The odor-deodorizing filter F for quickly deodorizing odors when exhausting odors filled in the room to the outside and exhausting clean air to the outdoors will be described below. It is well known that activated carbon, charcoal and the like absorb bad odors and deodorize them. However, when activated carbon or charcoal is used alone for deodorization, it has a drawback in that it absorbs moisture in the exhaust gas to deteriorate air permeability and deodorization performance, and the deodorization effect is greatly reduced. Therefore, the present inventor believes that the fiber mass of coconut husk is excellent in air permeability and easily absorbs moisture, and since it is a fiber mass having voids even when moisture is absorbed, the fiber mass of water easily evaporates together with water permeability. Since it is a lump, it can maintain a constantly dry feeling and has a property that it is hard to corrode and it can be washed and used repeatedly even if it is dirty, so if you install a fibrous lump of coconut husk as a moisture control material on the front of activated carbon or charcoal Focusing on the fact that the amount of water absorbed by activated carbon or charcoal is reduced and the deodorizing effect can be maintained, a deodorizing filter capable of maintaining the deodorizing effect for a long time is formed. The structure of the filter F is a container 1 formed in a box shape.
A ventilation plate 4 having a large number of holes or meshes is provided on the ventilation surfaces 2 and 3, and a partition plate 5 provided with a large number of holes or meshes like the ventilation surfaces 2 and 3 is provided between the ventilation surfaces 2 and 3. A fibrous lump coconut palm 6 formed in a range of about 3 mm to about 35 mm is inserted into one of the spaces separated by the partition plate 5, and activated carbon 7 or charcoal 7 is inserted into the other space.
The filter F was formed by inserting the block and sealing it. In the case of this example, one partition plate 5 is provided in the middle of the container 1, and a coconut shell 6 and activated carbon or charcoal 7 are respectively inserted and sealed on both sides thereof to form a filter F.
A plurality of partition plates 5 may be attached to the inside of the container 1 to provide a plurality of spaces, and lumps of coconut shell 6 and activated carbon or charcoal 7 may be inserted alternately at a plurality of locations. In addition, when the fibrous mass of coconut shell 6 and the mass of activated carbon or charcoal 7 inserted into mesh bag 8 are alternately mounted in container 1 to form and use filter F, the attachment / detachment / replacement operation is easy. Is more preferable. The above-mentioned filter F is installed at the exhaust port 9 provided on the wall surface or connected to the exhaust port 10 of the container 11 containing the kitchen waste, and the blower or the ventilation fan H
Forcibly exhaust the bad odor filled in the room or in the container 11 by passing it through the filter F to adsorb and remove the moisture or dust by the fibrous mass of the coconut husk 6, and then continue the deodorizing material such as activated carbon or charcoal 7. Thus, the odor is removed and the clean air is exhausted outdoors.

[0008] As described above, the present invention is intended to reduce fish chips generated in households, grocery stores, canteens, food processing factories, and the like.
It is made to suppress as much offensive odors as possible from kitchen garbage mixed with meat and vegetable waste, and to eliminate odor pollution by deodorizing, and contains more than 90% moisture. First, the vegetable waste is separated, and then the mixture of fish waste, meat waste, and the like is left in a drying room or placed in a container 11 provided with a drying device and subjected to a drying treatment. Means for controlling the water content to 40% or less to suppress odors generated from kitchen waste, and adding calcium silicate or lime to kitchen waste containing fish chips, meat chips, etc. The odor is reduced by adjusting the pH to 7 or more to control the odor generated from the kitchen waste. Perform processing flexibly according to the situation, It is obtained by configured to obtain a good malodor control effect of rates. In addition to the means for suppressing the generation of offensive odors generated from the kitchen waste,
In order to exhaust the bad smell filled in the inside to the outdoors, a fibrous mass 6 made of coconut husk and a mass of activated carbon or charcoal 7 are sealed in the box-shaped container 1 to form a filter F, and an indoor exhaust port or The filter F is attached to the exhaust port of the container, and the odor filled in the room or in the container 11 with the drying device is forcibly passed through the filter F by a blower or a ventilation fan H to exhaust the odor, thereby mounting the filter F. The odor is quickly and effectively deodorized by the synergistic effect of the fibrous mass 6 and the activated carbon or charcoal mass 7, and the clean air is exhausted outdoors to eliminate odor pollution. It was done. Therefore, by using the method for treating bad odor of kitchen waste according to the present invention in combination with the filter F for bad odor deodorization, the bad odor generated from the waste kitchen waste, which has been a problem so far, can be significantly suppressed and the indoor odor can be suppressed. Since the filled odor is deodorized and the clean air is exhausted outdoors, the odor pollution is eliminated and the living environment is greatly improved.
