[Detailed description of the invention]

[0001]

[Industrial applications] The present invention is applied to hotels, restaurants,
The present invention relates to the prevention of offensive odors in wastewater treatment devices such as grease straps and oil / water separators laid in food factories and the like. More specifically, air in a magnetic atmosphere acts to suppress the growth of anaerobic bacteria and generate odors. The present invention relates to a device that can eliminate the cause of the above.

[0002]

2. Description of the Related Art It is necessary to install grease traps and oil / water separators in food-related facilities such as hotels and restaurants in order to remove organic components such as oil and sewage from the wastewater during the wastewater treatment. Although it is obligatory, in the device, microorganisms are propagated using an organic component as a nutrient source, and when there are many anaerobic bacteria in the device, an odor component is generated, which causes the odor to spread around the device.

On the other hand, conventionally, (a) an exhaust pipe communicating with the outside air is communicated with a grease strap or an oil / water separation tank so as to dissipate generated odors, or (b) a liquid layer in the tank. Means are used to blow ozone into the inside to suppress the growth of various bacteria by its bactericidal action, or to add (c) a chemical or a deodorant.

[0004] However, depending on the above-mentioned means, in the means (a) using an exhaust pipe, it is extremely troublesome to attach a pipe to a tank and to perform piping. In the means (b), when a large amount of ozone is used, It may adversely affect the human body,
In (c), the effect is transient, and regular continuous administration is required, which has disadvantages such as increased labor and cost. Therefore, the current situation is that the inside of the tank is cleaned frequently by itself or entrusted to a contractor for cleaning.

[0005] On the other hand, it is known that magnetically treated air acts on odor components in the air and has a deodorizing power in living rooms, refrigerators, automobiles, and the like (Japanese Utility Model Application Laid-Open No. 1-104147).
It is not yet known to act on bacteria in wastewater containing organic components as described above, and performing aeration of air or the like on the wastewater treatment apparatus is not effective for air bubbles. It has been considered that the upward flow stirs the liquid layer and causes the outflow of organic components such as stored oil, which is not preferable.

[0006]

SUMMARY OF THE INVENTION The present invention has been made based on the above-described circumstances, and focuses on the fact that magnetically treated air is extremely effective in suppressing the growth of anaerobic bacteria.
In making the apparatus into an apparatus, it is intended to solve the above-mentioned problems such as the outflow of organic components and to develop an apparatus which can be easily maintained.

[0007]

The wastewater treatment apparatus according to the present invention is a wastewater treatment apparatus provided separately in a filtration chamber, an organic component storage chamber, and a trap chamber facing the inflow port through a casing with a partition plate.
A diffuser tube having a large number of pores is disposed at an upper position deviated from the main flow path of the drainage of the organic component storage chamber. It is characterized by ejecting the treated air to prevent decomposition of organic components by anaerobic bacteria. In this case, it is preferable to connect both ends of a rubber hose in which a micron-sized hole is formed in a bifurcated branch pipe. It is also preferable that the height of the air diffuser can be adjusted.

[0008]

When air is passed through a gap between magnets having a constant magnetic flux density, oxygen in the air is excited and the reactivity of oxygen increases, and when it is sent from the diffuser to the storage chamber,
It acts on anaerobic bacteria and suppresses their reproduction. At that time, since the air diffuser is disposed at an upper position deviated from the main flow path of the drainage of the organic component storage chamber, without stirring the drainage, and in order to squirt with bubbles as small as possible,
Since a large number of pores are formed, the upward flow has little movement, and the outflow of organic components is minimal. In addition, if the air diffuser is formed by connecting both ends of a rubber hose having a forked bifurcated pipe with a perforated hole, it can be easily installed according to the shape and size of the room. Furthermore, if the height of the air diffuser is adjustable, positioning in accordance with the flow path of drainage becomes easy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to an apparatus for storing and discharging organic components, such as a grease trap, an oil / water separator, and a combined treatment tank, for treating waste water, as shown in FIG.
Is divided into a filtration chamber 2, an organic component storage chamber 3, and a trap chamber 4 facing the inflow port by a partition plate. In the apparatus, when the organic component G is floating and the inside of the tank is in a closed state, the atmosphere becomes extremely lean in oxygen, and the organic component is used as a nutrient, and the conditions of suitable temperature and humidity are uniform, and anaerobic. Bacteria proliferate, and as a result, malodorous components such as hydrogen sulfide, methane gas, and ammonia are generated and dissipated to the surroundings, causing unpleasant malodor.

Therefore, in the present invention, magnetically treated air is sent into the organic component storage chamber 3 of the drainage device. Here, the magnetic treatment refers to sending air in a direction crossing the line of magnetic force in a gap between the N pole and the S pole in a permanent magnet or an electromagnet, and sending air containing oxygen in an atmosphere of the magnetic field. As shown in FIG. 4, for example, as shown in FIG. 4, a magnetic force of, for example, about 3000 gauss is applied to a ring-shaped permanent magnet so that the N pole and the S pole are opposed to each other, and the gap is set to one.
Set to about 5 mm, and send outside air with a blower.

The air subjected to the magnetization treatment is sent into the organic component storage chamber 3 of the wastewater treatment apparatus. At this time, when the magnetized air is ejected from the bottom of the storage chamber 3 as described above, The rising flow of the generated bubbles agitates the organic component, and a large amount of the organic component flows out of the apparatus. Therefore, in the present invention, the wastewater flowing in the device goes through the separation plates 5a and 5b after leaving the filtration chamber and enters the organic component storage chamber, where the organic components such as oil having a relatively small specific gravity float up. Paying attention to the fact that the water component with a large specific gravity does not flow to the upper part of the tank but flows to the lower layer, avoiding the main flow path of the lower layer,
An air diffuser 6 is provided on the upper part.

As shown in FIG. 3, the means for arranging the frame is such that four legs 7a are connected to vertical and horizontal support rods 7b and 7c, and the legs 7a are slidably combined with pipes having different diameters. It is desirable to form the base 7 and to make it adjustable in height.

The air diffuser 6 is preferably made of a rubber hose having a large number of pores of 15 to 300 microns, for example, about 50 microns. Using about 2 meters, it is connected to a bifurcated branch pipe 6a at both ends to form a ring (see FIG. 2A). Alternatively, when the room is small, the end of one rubber hose may be closed and the other may be connected to the air supply pipe from the magnetizing device (see FIG. 2B).

The air diffuser 6 is connected to the air supply pipe from the magnetizing device described above, and the pressure from the air supply pipe forms bubbles in the drainage water.
The magnetized structure is designed to eject air.

The air diffuser 6 may be disposed in the filtration chamber 2 and the trap chamber 4. However, the air diffusion pipe 6 is mainly composed of the organic component storage chamber 3, and the feed rate is supplied to the filtration chamber 2 and the trap chamber 4. To a small amount.

To explain the operation of the present invention, as shown in FIG. 4, when air is passed in a direction crossing the magnetic field lines of the magnetizing device, oxygen atoms contained in the air have four electrons in the P orbit. Since the electrons are contained in the pi antibonding orbit with high energy, they have unpaired electrons and are therefore paramagnetic atoms. When the magnetic field is applied to the atoms, the outermost nuclear electrons become excited. , Oxygen will increase the reactivity.

Next, the magnetically treated air is sent to the lower part of the storage chamber 3 in which the organic components are stored, and is spouted out of the diffuser 6 into the liquid. The magnetized oxygen acts on the anaerobic bacteria that are breeding using as a nutrient, and the number of the anaerobic bacteria is greatly reduced. At this time, filtration room 2
Drainage from the reservoir enters the storage chamber 3 through the diaphragms 5a and 5b,
Organic components such as oil having a low specific gravity float on the top, and most of the wastewater enters the trap chamber 4 through the lower layer near the bottom, so that the main flow path is not reached by the height at which the diffuser 6 is located. Not reach. Therefore, the bubbles ejected from the diffuser 6
Ascends without intersecting with the main flow path, and because it consists of as small pores as several microns, statically jets out, allowing organic components to flow out without agitating the drain flow path There is no fear.

In order to install the apparatus, the frame 7 is disposed in the storage chamber 3, the diffuser 6 is placed thereon, and the air is blown from the magnetizing device. At this time, if the air diffuser 6 is formed of a flexible material such as a rubber hose, it can be easily deformed according to the shape and size of the room. Further, even when cleaning the inside of the apparatus, the air diffuser 6 and the frame base 7 can be easily removed from the room, so that the installation is not hindered.

As a result, the inside of the wastewater treatment apparatus always comes into contact with the magnetized air, and the generation of hydrogen sulfide, ammonia, methane, and the like as malodorous components generated by the anaerobic bacteria is minimized as much as possible. It prevents the occurrence and does not deteriorate the surrounding environment.

[0020]

[Effect of the Invention] The present invention relating to the above configuration and operation is as follows.
The magnetizing treatment suppresses the growth of anaerobic bacteria and has an excellent effect of being able to cut off what has caused the wastewater treatment device to cause bad smell in hotels, restaurants, food service centers, food factories, and the like. . At this time, the invention is extremely practical because the magnetized air can be brought into contact with the drainage without causing the outflow of the organic components, and the maintenance such as installation and cleaning is easy.
