Description of the Related Art Conventionally, this type of processing apparatus is equipped with a floating oil / fat separation tank or an oil adsorption mat for commercial use, forcing the floating oil / fat to be taken out or adsorbing oil to the oil adsorption mat. I change the lever mat regularly. Further, in a domestic wastewater treatment equipment, an anaerobic filter bed tank and a contact aeration tank are provided, and soil containing anaerobic bacteria is put into the anaerobic filter bed tank, and the organic matter in the wastewater is discharged in this anaerobic filter bed tank. After decomposing by the anaerobic bacteria generated on the surface of the filter medium, this wastewater is mixed and stirred with the air jetted from the diffuser pipe in the contact aeration tank, and it is sufficiently contacted with the biofilm on the surface of the contact medium to be oxidized, Removing nutrient substrates.

However, in the above-mentioned commercial treatment equipment, although the oil and fat can be removed from the waste water itself, the work of taking it out is troublesome because it must be carried out in an environment with a bad odor, and it is taken out individually or by adsorbing it on a mat. The fats and oils cannot be discarded as they are, and there is a problem that they must be incinerated or reprocessed. In household treatment equipment, soil quality differs due to regional differences in soil containing anaerobic bacteria and the extent of contamination with pesticides, herbicides, etc., causing variations in the bacteria's degrading power, and the treatment equipment functions effectively. There was a failure not to. Furthermore, because methane gas, hydrogen sulfide, mercaptan, etc. generated in the anaerobic filter bed tank have a very strong offensive odor, the amount of biological sludge that can be retained on the contact material surface of the contact aeration tank is limited. However, there is a drawback that maintenance work such as backwashing the contact material is required.

In order to solve these problems, one of the inventors of the present invention is that the treatment tank has a drainage inlet and a treated water outlet.
The amount of ozone generated is adjusted by adjusting the voltage or frequency of the high-frequency high-voltage power supply for applying the high-frequency AC high voltage to the ozone generation element, and the generated ozone is adjusted by the ozone ejection means into the wastewater in the treatment tank.

In the waste water treatment apparatus configured as described above, when a negative potential is applied to the tubular body by the ionizer of the microorganism maintenance means to negatively ionize the ceramic dielectric contained in the tubular body, the composite charged to a positive potential is used. Microbes are maintained in the wastewater. In this state, when air containing ozone is ejected to the waste water by the ozone ejecting means, the microorganisms are activated by ozone, and various decomposing effects including the deodorizing action of ozone and the fat and oil decomposing action and the fat and oil decomposing action of the complex microorganisms,
Organic substances in wastewater can be surely decomposed while dissipating the bad smell of wastewater.

a, the electromagnetic valve 37 for tap water, the regulators of the ozonizers 54 to 56, and the ionizer 59.

The operation of the thus-configured automatic introduction device for complex microorganisms will be described. When a power switch (not shown) is turned on, the controller 64 first turns on the tap water solenoid valve 37 to open the water pipe 34, and at the same time, turns on the first speed reducer-equipped motor 32a and the second speed reducer-equipped motor 24a. The complex microorganisms 21 in the hopper 23 are scraped off by the blade 2
By the rotation of 4c, it falls into the mixer box 27 through the microorganism dropping hole 23b, is mixed with the tap water supplied into the box 27 to form a complex microorganism solution 26, and passes through the supply pipe 28 to each processing chamber 16 of the processing tank 10. ~ 18.
The time for turning on the tap water solenoid valve 37 is 15 seconds to 5 minutes, and the time for turning on the second reduction gear motor 24a to rotate the scraping blade 24c is 5 seconds to 30 seconds.

On the other hand, the controller 64 is the ozonizer 54.
~ 56 are activated and pump 58 is subsequently driven. Air containing about 1 to 2% by volume of ozone is ejected from nozzles 41 to 43 through conduits 51 to 53. At the same time, the controller 64 operates the ionizer 59 to operate electrodes (not shown).
A negative potential is applied to the ceramic dielectric (not shown) contained in the cylindrical body (not shown) to be negatively ionized. As a result, the complex microorganisms 21 such as aerobic bacteria and bacteria, which are supplied by the microorganism supply means 22 and are charged to a positive potential, are attracted and maintained by the ceramic dielectric. Ionizer 5
When 9 is deactivated, the microorganisms leave the ceramic dielectric and disperse in the water of process chambers 16-18. Although not shown, it is preferable to provide a flow rate sensor in the inflow pipe 19 to disable the ionizer 59 when the inflow amount increases.

The microorganism-maintaining sensor 47 indicates that the oxidation-reduction potential of the treated water has risen due to the air containing ozone ejected from the nozzles 41 to 43 and that the complex microorganisms 21 have reached the range of 300 to 400 mV where they are actively acting. When detected, the controller 64 lowers the voltage of the ozonizers 54 to 56 by a regulator (not shown) so as not to sterilize the microorganism 21, and reduces the ozone generation amount. The redox potential of wastewater is 3
When the voltage drops below 00 mV, the regulator again increases the ozone generation amount. To maintain the redox potential in the range of 300-400 mV, in this example 1000 liters of water
The controller 64 controls each of the ozonizers 54 to 56 so as to generate 100 mg of ozone per hour.
Further, when the water quality sensor 61 detects that the oil film 65 in the processing chamber 18 has become equal to or greater than a predetermined thickness, the controller 64 determines that the complex microorganisms 21 in the wastewater of the treatment tank 10 has decreased, and the microorganism supply means 22 is activated. The composite microorganisms 21 are operated and supplied to the processing chambers 16 to 18 of the processing tank 10.

As a result, the above-mentioned various actions of the microorganisms 21 dispersed in water, the oxidizing action of ozone, and the action of decomposing fats and oils decompose the fats and oils in the wastewater and eliminate the malodor. For example, it is considered that the oil and fat contained in the waste water is decomposed in the following process, as shown in FIG. Due to the synergistic action of the composite microorganism 21 and ozone, a part of the oil and fat is taken into the microorganism 21 and becomes the food, and the excrement of the microorganism 21 is decomposed into carbon dioxide and water by ozone. The rest of the oil and fat is beta-oxidized by a degrading enzyme secreted from the microorganism 21 and decomposed, and the glycerin-state and fatty acid-state which are the decomposition products are oxidized by ozone and the microorganism 21 and finally decomposed into carbon dioxide and water. To be done. Ozone oxidizes fats and oils and promotes the growth of microorganisms 21.

Ozone is appropriately jetted to adjust the redox potential to −
By controlling in the range of 300 to -400 mV, complex microorganisms such as aerobic bacteria and mold grow, and the microorganisms are maintained in the treatment tank 10 by the microorganism maintenance device 46 controlled by the ionizer 47. Wastewater is treated tank 10
The oil and fat decomposing ability does not deteriorate even when the oil passes continuously for a long time, and the wastewater can be continuously purified. The waste water is purified as it goes from the treatment chamber 16 to the treatment chambers 17 and 18, and the treated water from which the oil and fat components are decomposed and the bad odor disappears is guided from the bottom of the treatment tank 10 to the guide cylinder 48 and flows out through the outflow pipe 20. .

Table 1 shows that the hourly average wastewater inflow is 2.5.
m ^3, the water quality data wastewater after treatment time maximum inflow was collected by drainage and outflow pipe 20 for preprocessing collected at inlet pipe 19 when treated with the apparatus of this embodiment the kitchen waste water 5.0 m ³ Is. Water quality was measured by the JIS-K-0102 method.

As described above, according to the present invention, the pre-cultured complex microorganisms are maintained in the wastewater of the treatment tank, and ozone is ejected together with air into the wastewater in which the complex microorganisms are maintained to discharge the wastewater. It is configured to automatically feed complex microorganisms into wastewater by decomposing organic matter in the wastewater and detecting output of a water quality sensor that detects the treatment status of wastewater in the treatment tank or output of a timer that measures a predetermined time. The workability of the wastewater treatment becomes extremely easy as compared with the conventional wastewater treatment equipment in which the complex microorganisms have to be manually put into the treatment tank at a predetermined amount every predetermined time. Further, even if the above-mentioned complex microorganisms are formed into a powder or granules, or liquid, block-like or paste-like, a water quality sensor for detecting the treatment situation of the wastewater in the treatment tank with these complex microorganisms. The same effect as described above can be obtained by automatically supplying into the drainage by the detection output or the output of the timer that measures the predetermined time.

Further, according to the present invention, similarly to the conventional wastewater treatment equipment, ozone activates various actions of the complex microorganisms, and at the same time, deodorizes ozone and decomposes fats and oils, and decomposes fats and oils of the complex microorganisms. By combining with various decomposing actions including, and maintaining complex microorganisms that easily flow out during processing, it is possible to continuously remove wastewater without specially removing oil and fat from wastewater discharged from commercial kitchens. It is possible to surely decompose the oil and fat in the wastewater while dissipating the bad odor. In particular, since the organic substances contained in the waste water are mainly decomposed into carbon dioxide and water, no sludge is generated, and the maintenance and inspection of the treatment device can be easily performed. Furthermore, household wastewater can be purified to a certain water quality standard without emitting offensive odor.
