Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a technical means for purifying wastewater, etc. by using the decomposition energy of useful microorganisms, BSK bacteria, and specifically,
A water purifier containing SK bacteria or enzymes secreted by it;
This relates to a cleaning system for kitchen floors, etc. that uses this purifying agent.

(Prior Art) Conventionally, there is no technology that artificially utilizes the phenomenon in which BSK bacteria, which are useful microorganisms, actively create an environment convenient for themselves and is useful for cleaning and environmental management.

On the other hand, cleaning the floors of kitchen facilities such as restaurants and food factories is an important task in terms of hygiene management, and is generally carried out by brushing using detergent and water. and,
In order to save labor, methods such as the use of high-temperature water using a high-pressure jetter and automatic floor cleaning machines that use detergent have been developed, but mechanization and automation are difficult in this field. The floor surface is regularly disinfected by spraying a disinfectant. These operations primarily involve the greatest proportion of labor and water usage to remove greasy bone deposits.

(Problems to be Solved by the Invention) However, in the conventional floor cleaning method described above, the amount of food that is high in fat is being cooked, and the amount of water used and the labor involved are increasing from a hygienic standpoint. The costs are extremely high. Basically, no major technological changes have been made, other than the emphasis on chemical cleaning methods compared to the traditional physical cleaning methods. Technological reforms are desired to reduce costs.

The present invention was created to solve these problems, and by introducing a microbial cleaning method that has lagged behind physical and chemical cleaning methods, it aims to save labor and improve efficiency of cleaning work, and reduce pollution. The purpose of the present invention is to provide a safe and reliable water purifying agent that does not involve water purification, and a washing system for kitchen floors, etc., using the same.

(Means for Solving the Problems) In order to achieve this object, the water purifying agent of the present invention
It consists of a combination of K bacteria and ACF.

In addition, the cleaning system for kitchen floors etc. using the water purifying agent of the present invention is equipped with a BSK bacteria injector and ACF as a culture medium for the BSK bacteria to activate the BSK bacteria and produce bio-water. A reactor, a piping line connected to the bioreactor to supply bio-water to the kitchen floor, etc., and a piping line connected to the bioreactor and piping line to automatically control the adjustment and supply of bio-water according to the cleaning time. It is characterized by being comprised of an automatic control unit that

(For use) In the above water purification agent, BSK bacteria has a strong affinity with ACF, and due to their combination, BSK bacteria can suppress the proliferation of various bacteria and promote growth activation, secreting and producing enzymes. do.

Therefore, the activated BSK bacteria and the enzymes produced purify wastewater, decompose scum, and eliminate bad odors.

In the kitchen floor cleaning system described above, bio-water is automatically sprayed onto the kitchen floor, etc., thereby converting the energy from the decomposition of BSK gold and the enzymes it secretes into energy for cleaning work.

That is, by using the decomposition energy for daily kitchen floor cleaning, BSK bacteria and its enzymes biodegrade fats and the like that adhere to the floor surface for 24 hours.

(Embodiment) Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic side view of the kitchen floor washing system of the present invention. As shown in the figure, this kitchen floor washing system 1 includes a bioreactor 2 that activates BSK bacteria and prepares biowater, and a bioreactor 2 that is connected to the bioreactor 2 and prepares biowater. and a piping line 3 to be supplied to the kitchen floor, and an automatic control unit 4 connected to the bioreactor 2 and the piping line 3 to automatically control the adjustment and supply of biowater depending on the cleaning time. It is composed of

Specifically, the bioreactor 2 includes a tank 5 into which clean water is introduced, and an ACF (fibrous carbon) 6 built in this tank 5 and serving as a culture medium to supply a carbon source to the BSK bacteria.
A bio-injector 7 is provided above the tank 5 to introduce BSK bacteria, and a growth environment regulator 8 is provided below the tank 5 to provide air, heat, etc. to the BSK bacteria. There is.

The tank 5 has a standard capacity of about 500° C., and can be selected with a capacity that is increased or decreased depending on the scale and amount of use.

Specifically, a water supply pipe 10 equipped with a backflow prevention valve 9 is connected to the upper part of the tank 5, and a water level control valve is further provided to control the water level of the water introduced slightly downward from the connection port of the water supply pipe 10. 11 are provided.

The ACF 6 is placed stationary in the center of the tank 5 formed into a block shape. However, the method of standing still can be in the form of several shelves above and below. Alternatively, the ACF 6 can be formed into a short cylindrical shape with a small diameter (not shown), and a large number of ACFs 6 can be enclosed in a basket frame that is left stationary like a shelf to make a semi-fluid type. Furthermore, the ACF 6 can be configured to circulate within the cage frame as a fluid carrier (not shown) having a specific gravity slightly heavier than water.

ACF6 is called fibrous carbon or carbon fiber, and the inventors' experiments have confirmed that it has a strong affinity for BSK bacteria, makes them adhere well, provides the carbon source necessary for their growth, and is suitable as a culture medium. (Experiment example ■■ below).

BSK bacteria was discovered in the soil by the present inventors. It belongs to Bacillus subtilis, is a Durham-positive bacterium that has antagonistic properties against harmful bacteria such as putrefaction bacteria, and is a reducing bacterium. It is similar to Bacillus subtilis, but its properties are different. Under a microscope, they were observed as long chains when singly or in pairs. This BSK bacterium itself has already been applied for as a biopharmaceutical, and was deposited as FIKEN No. 9643 at that time.

This BSK bacterium can effectively decompose oily bones and cellulose, which are difficult-to-decompose substances that many aerobic microorganisms are not good at, and at the same time has good functionality as an antagonist that controls other putrefactive and disease-causing bacteria. It has been confirmed that (Experiment Example, II) In addition, it is certain that the production of unique enzymes serves as a utility value, considering that decomposition energy exists only in the liquid component of the prepared biowater. This has the significance of producing and adjusting biowater in the bioreactor 2.

The bio input device 7 opens the input port 13 by rotating the drum 12.
In many cases, a structure is used in which the inactivated spore-shaped BSK bacteria is released into the block-shaped ACF 6 in the tank 5 either alone or with an appropriate amount of nutrients and then by the operation of the small motor 14. It is not limited to structure.

The growth environment regulator 8 consists of a temperature regulator 15 and an air supply regulator 16. Among them, the temperature regulator 15 is configured to inspect and operate a heater 17 horizontally suspended below the block-shaped ACF 6 by operating a thermostat 18.

On the other hand, the air supply regulator 16 has a nozzle 19 placed horizontally below the heater 17 and communicates with an air pump 21 via a vibrator 20 to blow out an appropriate amount of air and circulate it within the tank 5.

The bioreactor 2, which is configured as described above, connects the piping line 3 below the tank 5 and converts tap water into biowater in advance to produce and adjust highly functional biowater for floor cleaning. . One of the main objectives is to produce enzymes based on BSK bacteria and ACF.

In other words, in the microbial world, there is naturally competition between microorganisms, and there are many unpredictable types of environmental resistance, and BSK always maintains a prevailing balance.
The key is to prepare the bacteria inside the bioreactor in order to make them work, and it can be said to be a low-cost biotechnology.

In particular, many biologic preparations are currently on sale for decomposing fats and oils in the kitchen and for odor control, but they must be diluted in advance in a bucket or the like and left for a certain period of time, which requires preparation. There are many troublesome things and parts that leak out,
This reduces economic efficiency and effectiveness, making it difficult to use due to cost. Furthermore, there is no technology for spraying the diluted solution on the floor.

Under these circumstances, there is a significance to the existence of the bioreactor 2 itself as described above, and there is also significance in incorporating it into the kitchen floor washing system 1.

By the way, as mentioned above, in this kitchen floor washing system 1, a piping line 3 is connected to this bioreactor 2, and an electromagnetic pulp 22 and a pressure-feeding vibrator 23 are interposed in this piping line 3 in order. A coupling 24 for connecting a spray hose is provided at the tip end of the piping line.

As shown in FIG. 2, the piping line 3 is arranged along the side wall 26 of the kitchen 25, and the tank 5 of the bioreactor 2 to which it is connected is installed outside the side wall 26. The control panel 27 is installed on the side wall 26 near the tank 5.
is installed inside.

The automatic control unit 4 connects the bioreactor 2 and the signal line 28.
and a power line 29 to automatically control the production, adjustment and supply of bio-water. For example, when the clean water introduced into the tank 5 reaches a predetermined flow rate, a signal is obtained from the water level control valve 11 to turn off the power source for introducing the clean water, and the temperature of the introduced clean water is detected. A signal is received from the thermostat 18 to turn the heater 17 on and off, and a signal from a sensor (not shown) that detects the transparency of the biowater is received to operate the air pump 21 to generate a circulating flow while supplying oxygen from the jet nozzle 19. It also automatically commands the opening of the electromagnetic valve 22 and the operation of the pressure pump 23 upon receiving a signal of a cleaning time suitable for spraying the prepared bio-water onto the kitchen floor. It is. In addition, 30 is a water hose, 31 is a floor, 32 is a drain, and 33 is a restaurant.

Regarding the control of BSK bacteria growth in bioreactor 2, in order to complete the production adjustment that allows biowater to be supplied and sprayed to the floor washing section, temperature, nutrients and input amount, time,
It has been verified from ACF (carrier) and other aspects (Experimental Examples I and II), and the maximum cleaning function is demonstrated by heating the sprayed stool during the first half of the growth phase of BSK bacteria, when enzyme production is high. It has been confirmed that

After the production adjustment is completed so that the bio water can be sprayed, each control section in the tank 5 is stopped, and consideration should be given to controlling the generation of odor microorganisms when stored there by using a special carrier. is being done.

Next, the operation of the kitchen floor washing system configured as described above will be explained.

When the timer sends a signal to start cleaning to the computer in the control unit 47, the solenoid valve 22 is opened and the pressure pump 23 is activated, and the bio-water that has been manufactured and adjusted to a sprayable state is sent from the tank 5 of the bioreactor 2 to the pipe. Water is sprinkled onto the floor 31 of the kitchen 25 from a spray hose 30 that is supplied to the line 3 and connected to the coupling 24 .

The bio-water sprinkled in this manner is spread almost evenly over the surface of the floor 31, a portion of which evaporates, and a portion of which flows into the drainage ditch 32. Then, the BSK bacteria and the enzymes they produce adhere to the floor surface and decompose fat, cellulose, and other sludge. In addition, BSK bacteria and the enzymes produced by the BSK bacteria purify the wastewater, decompose scum, and eliminate bad odors in all the drainage system channels connected by the biowater flowing into the drainage ditch 32.

In this way, in this system 1, the tap water itself used for floor washing has bio-functionality, and there is no need for special manual preparation of the bio-water in advance. The enzymes produced by these enzymes act on the floor surface to break down oils and fats, which are then washed out by water into the drainage system.

Therefore, this system 1 has the effect of permanent decomposition and deodorization even in drains, grease traps, drain pipes, bits, septic tanks, public sewers, etc., as well as environmental pollution, especially against the odor of building bits, sludge, scum, etc. It can be said to be a new technology that has advantages in processing industrial waste and can solve environmental problems on a global scale.

(Effect of the invention) In summary, in the first invention, ACF as a carbon source
Since a water purifier is produced by combining BSK and BSK bacteria, the affinity between the two is strong, and the growth of other bacteria can be suppressed, making it possible to improve the efficiency of cleaning kitchen floors and reduce costs. Of course, it can be used for a wide range of purposes such as purifying pool water and goldfish drumsticks.

In addition, the second invention is configured to automatically supply and spray bio-water, which is automatically produced and adjusted with tap water, ACF, and BSK bacteria, as cleaning water for the kitchen floor, etc., so that the following excellent effects can be achieved. Demonstrate.

The fibers were of uniform size.

When this carbon fiber was put into the scum of Bilvit along with BSK bacteria, the same observation as above after 7 days showed that long, string-like bacteria were wrapped around the carbon fiber as shown in Figure 4. Six scums were observed simultaneously in it. Also, when observing this under high magnification, as shown in Figure 5, there is a size 2 on the surface of the carbon fiber.
A large number of bacteria of ~5 μm were attached. Among these are B
It was later observed to be SK bacteria.

These findings suggested that BSK bacteria had a very good affinity for carbon fiber. That is, it seems that the BSK bacteria take in carbon using carbon fiber as a nutrient source.
