Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an apparatus for decomposing and purifying fats and oils contained in wastewater from, for example, kitchen equipment using a microbial agent.

[0002]

[Prior art]

 Wastewater from kitchen equipment contains a large amount of fats and oils, and if this contaminated wastewater flows into the wastewater as it is, it emits offensive odors and undesired effects such as environmental pollution. Occurs. For this reason, it is required to remove oils and fats from the wastewater and purify it to a water quality that does not pollute the environment. Many separation methods are used to separate oils and fats from wastewater, from simple methods using oil filters and filtration media to full-scale methods of decomposing and removing wastewater from oil and fat mixtures. ing.

[0003] Another method that has recently attracted attention is to use a microbial agent. This method utilizes the growth effect between microorganisms and the effect of increasing the ability to secrete enzymes, and has been confirmed to have a certain effect on degradation and purification. The method of decomposing and purifying fats and oils using this microbial agent does not require a large-sized apparatus, requires no manual labor, has extremely low operation costs, and can achieve desired results.

[0004] In the treatment of fats and oils using a microbial agent, it is required to supply the microbial agent to the fats and oils without bias in order to efficiently treat wastewater. Fats and oils are often present unevenly in each part of the wastewater, so it is necessary to disperse the fats and oils at the same time to feed the microbial agent so that there is no shortage. No. If a microbial agent is sent to the finely divided fats and oils, the number of microbial agents that come into contact with the fats and oils will increase accordingly, and as a result, the decomposition and purification of the fats and oils will proceed.

[0005]

[Problems to be solved by the invention]

 However, at present, the refinement of fats and oils is not enough to achieve the refinement, such as by manual operation or by arranging a perforated pipe on the bottom of the drainage tank to send oxygen. . If the microbial agent is supplied in a situation where dispersion and micronization do not proceed sufficiently, the microbial agent is supplied regardless of the actual amount of fats and oils in each part, and the desired microbial agent function may be developed in some places. Supply of the required amount of microbial agent. In this case, if the amount of the deficiency is large, the decomposition of the fats and oils will not be sustained, and the fats and oils that cannot be processed will remain.

In order to deal with such a problem, for example, it is conceivable that the supply amount is increased in advance, but if the supply amount exceeds the originally required amount, wasteful costs are incurred over a long period of time. Is not preferred. There is also a method of sending an appropriate amount of a microbial agent while checking the situation. However, such a method is not preferable because it takes too much time until the action of the microbial agent takes effect.

[0007] Therefore, an object of the present invention is to make it possible to supply an appropriate amount of a microbial agent while reliably refining the oils and fats in wastewater in order to decompose and purify the oils and fats using a microbial agent. An object of the present invention is to provide a class decomposition purification apparatus.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention comprises a wastewater tank for storing wastewater containing oils and fats, and a distributor provided at the bottom of the wastewater tank and having a perforated tube for blowing air into the wastewater. The porous tube is located on the bottom of the wastewater tank so that the air blown into the wastewater reaches the entire area of the tank.

In the present invention, when the wastewater tank is full of wastewater containing oils and fats, the air sent to the distributor is blown out into the wastewater. The distributor composed of perforated pipes is arranged so that the perforated pipes are located around the bottom of the wastewater tank, and the air bubbles generated by the air sent into the wastewater spread throughout the tank and come into contact with oils and fats at various places. Then, the gathered oils and fats are divided and become finer. A microbial agent is supplied to the finely divided fats and oils, and the action of the microbial agent decomposes and purifies the fats and oils.

[0010] Thus, by keeping the fats and oils in an unbiased state, it is possible to supply an appropriate amount of the microbial agent. This makes it possible to prevent the processing from stalling due to insufficient supply of the microbial agent, and to reduce the amount of microbial agent wasted due to excessive supply.

[0011]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, the decomposition and purification apparatus of the present invention has a wastewater tank 1 for storing wastewater. The wastewater tank 1 is surrounded by flat plates 2 and 3 having front and rear surfaces forming partitions, and flat plates 4 and 5 having both sides forming partitions. Further, the bottom is sealed with a bottom plate 6. Further, a distributor 7 having a perforated tube, which blows air into the wastewater, is provided at the bottom of the wastewater tank 1. Further, the wastewater sent into the wastewater tank 1 is desirably subjected to coarse dust removal treatment in the preceding tank.

An air source 8 is provided outside the wastewater tank 1. The distributor 7 is connected to the air source 8 via an air system 9. Further, the microbial agent supply device includes a microbial agent supply device 10 that supplies a microbial agent into the wastewater tank 1 and includes a microbial agent injector described later.

Details of the distributor 7 are shown in FIGS. As shown in FIG. 2, the distributor 7 includes three perforated pipes 11a, 11b, 11c, one connecting pipe 12, and four connecting pipes 11a, 11b, 11c and the connecting pipe 12. Elbow 13 and two cheeses 14. The components of the distributor 7 are internally connected to each other, and are connected to the external air system 9 and the cheese 14.

Each of the porous tubes 11a, 11b, and 11c has a large number of through-holes formed therein, and the air press-fitted through these through-holes is configured to be blown out into fine bubbles, ie, an air shower. I have. When the distributor 7 is placed in the wastewater tank 1, the portions of the perforated pipes 11a, 11b, 11c are each preferably arranged on the bottom surface and close to the wall surface. By blowing air from the bottom surface, it spreads and rises in the form of an air shower upward, so that it can widely contact oils and fats.

FIG. 3 shows another example of the distributor 7. When the distributor 7 is placed in the wastewater tank 1, the portions of the perforated pipes 11a, 11b, and 11c are provided with a portion arranged close to the bottom surface and a portion placed at the center in the wastewater tank 1. Portions of the perforated pipes 11a, 11b and 11c are connected by joints 18 and 19, and air is sent to the entire wastewater tank 1. This means that when air is blown from the bottom surface, it spreads upward and expands the range of ascent, and can come into wide contact with oils and fats.

The microbial agent supply device 10 is a supply device such as a hose, and preferably supplies a constant amount from above the wastewater tank. Further, an injector for a microbial agent as shown in FIG. 4 may be used. The microbial agent injector 15 shown in FIG. 4 includes a microbial agent delivery hole 16 and a connector 17 connected to one end of a hose of the microbial agent supply device 10. The microbial agent injector 15 is portable, that is, portable, and can be used by placing it in the tank from anywhere above the wastewater tank 1.

The present embodiment is configured as described above. For example, wastewater containing oils and fats generated in kitchen equipment is removed from the air source 8 when coarse waste is removed in the front tank and the wastewater tank 1 is filled. Is guided to a distributor 7 placed at the bottom of the wastewater tank 1. This air is blown into the wastewater as a number of bubbles from the through holes of the perforated pipes 11a, 11b, 11c of the distributor 7. At this time, the air is blown from the perforated pipes 11a, 11b, 11c near each bottom face so as to reach the whole area in the tank.

The air blown into the wastewater generates bubbles, causing aeration, and the bubbles and the fats and oils come into contact at various places in the wastewater, so that the gathered fats and oils are divided and finely divided. That is, fats and oils are refined. An appropriate amount of a microbial agent that decomposes the finely divided fats and oils is supplied from above. For the supply of the microbial agent, the microbial agent is supplied from the hose or the microbial agent injector 15 shown in FIG. Since the finely divided fats and oils are widely dispersed in the tank, microbial agents can be distributed evenly by the action of bubbles.

The microorganisms in the microbial agent repeat growth and secrete enzymes. The action of this enzyme breaks down oils and fats and removes wastewater stains. In other words, water of desirable quality that does not pollute the environment due to purification is obtained.

In the present embodiment, fats and oils are atomized by air blown so as to spread over the entire area in the tank, and a microbial agent is sent to the finely divided fats and oils. The microbial agent can be supplied, and it is possible to prevent problems such as a shortage of the microbial agent from being supplied and the processing not proceeding. Also, it is possible to reduce the amount of microbial agent wasted due to excessive supply.

Although the perforated pipes 11a, 11b, and 11c of the distributor 7 according to the present embodiment are composed of three pipes, a total of four perforated pipes that are blown out to the center of the tank are added. It may be composed of

Further, a single perforated tube may be added so as to blow out to four surfaces in the tank, and the tank may be constituted by a total of four tubes. Depending on the size of the wastewater tank 1, for example, one perforated tube on the rear surface may be omitted and two perforated tubes may be used.

As described above, in the present embodiment, in order to decompose and purify fats and oils, the fats and oils are surely finely divided and a microbial agent is sent to the finely divided fats and oils. Agent can be supplied, and it becomes possible to prevent the processing from stalling due to insufficient supply of the microbial agent. In addition, it is possible to reduce the amount of microbial agents that are wasted due to excessive supply.
