Regardless of the public sewage, when flowing into the septic tank, the fats and oils in the wastewater hindered the decomposition and purification of microorganisms in the septic tank, and as a result, the purification power of the septic tank itself was reduced, and the water was discharged into the river without being purified. In addition, when flowing directly into a river, microorganisms inhabiting the river were unable to decompose oils and fats, died, and accumulated as sludge.

ものである。Conventionally, there is no method for decomposing and purifying oils and fats contained in domestic wastewater. However, also in this combined septic tank, when animal and vegetable fats and oils flow in, the purification capacity is extremely reduced, and unpurified wastewater is discharged to rivers and the like. If the combined septic tank is not installed, wastewater containing a large amount of oil and fat flows out to rivers and the like as it is. With conventional methods, rivers are becoming increasingly polluted, and clean rivers disappear from the ground. Pollution from domestic wastewater has destroyed the life systems of rivers, and even the sea systems. Currently, industrial wastewater is under strict regulations and monitored by the government. However, there is little regulation on household wastewater, which accounts for about 80% of the wastewater. Under such circumstances, the present invention intends to decompose and purify wastewater containing animal and vegetable fats and oils discharged from general households, which occupy most of the pollution of rivers, in households and discharge them.

The inflowing fats and oils float on the water surface due to the difference in specific gravity, and are adsorbed by the fats and oils adsorbent (13) in the upper part. Here as well, the microorganisms are decomposed by fat-and-oil-degrading microorganisms, but if the fats and oils are large, they accumulate on the water surface.

The fat or oil to be removed is completely adsorbed by the fat or oil adsorbent (23). As a result, the fats and oils do not flow out of the water outlet (4). The fat and oil accumulated and floated inside the blower (30) is controlled by a timer (1) from the time when the use of the kitchen is finished to the time when the use is started.
Operated by 2), the first tank (5), the second tank (6), the third tank
The inside of the tank (7) and the fourth tank (8) are aerated by a diffuser tube. It should be noted that if the aeration is constantly performed, the fats and oils are discharged as they are without being separated. Therefore, in the present invention, the aeration is not performed during use of the kitchen. Blower (30)
In order to create an environment in which the microorganisms in the device easily exert their ability, the temperature of the air to be sent out is increased through a heater (31), distributed by a distributor (32), aerated from a diffuser (15), and the internal water temperature is increased. Is raised to about 30 ° C. The final tank (10) has an oil adsorbent (2
3) At the bottom, an adsorbent such as activated carbon is provided to perform adsorption filtration of fine suspended matter. In addition, it is also possible to return the floating oil and fat to the fourth tank by a small submersible pump in the fifth tank. In the first tank, the oil / fat adsorption mats (13) are provided above and below the inflow port. However, if aeration is performed in a state where the detergent is mixed, a large amount of foam is generated. Raw water containing a large amount of fats and oils (normal hexane extractables 14)

をする役目もしている。FIG. 7 is a detailed sectional view of the apparatus for decomposing and purifying a drainage grease according to the present invention. It is necessary to prepare several types of this mounting diameter according to the ready-made sink. A dedicated microorganism for decomposing fats and oils is transferred to the fat and oil adsorbent (42) in the filter (41), and the fats and oils in the wastewater are adsorbed and decomposed. What is important here is the habitat of microorganisms.
Generally, hot water is often used in sinks. However, generally known microorganisms cannot live at such high temperatures. However, the special-purpose microorganism used in the present invention is a microorganism that has been cultured at a high temperature in a special environment with fats and oils as a staple food and can inhabit even at 100 ° C. Therefore, the present invention can be implemented. The fat / oil adsorbent (42) used in the present invention has three to four layers, and the fat / oil adsorbent (13) used in the drainage tank (1) and the adsorbent (23) such as polypropylene are used. I'm using This can be anything that can inhabit microorganisms and adsorb fats and oils. The fat adsorbent can be used repeatedly since microorganisms immediately decompose the adsorbed fat. However, it gradually becomes clogged with small meals of food, so that it can be replaced every six months. This sink-mount type device also serves to adjust so that a large amount of waste water to the household waste oil / fat decomposition / purification device does not flow at a stretch and overflow from the grease trap type drain tank (1).

いものである。According to the present invention, it is possible to purify kitchen wastewater which accounts for most of environmental pollution in rivers. Furthermore, the dedicated microorganism used in the present invention is high in nutrients because it is mainly composed of animal and vegetable oils and fats, and other microorganisms eat this microorganism, and other small animals eat this bacteria. A food chain occurs. Therefore, as a result of using the present invention, it has been obtained that almost no sludge is generated in an ordinary fat and oil decomposition and purification apparatus or the like. On the contrary, the result was that the sludge that had accumulated up to now disappeared. Now that rivers are becoming increasingly polluted, it is the duty of each household to purify domestic wastewater and restore clean rivers and seas. In addition, when the household waste oil / fat decomposition / purification apparatus of the present invention is used, there is also a great effect that waste oil of tempura oil usually used at home can be flowed as it is and decomposed and purified in the apparatus. Nothing is more difficult to treat in ordinary households than waste tempura oil. These days there are things like oil solids, but the treatment is still cumbersome.
Further, the apparatus for decomposing and purifying domestic waste oil and fat according to the present invention is large enough to be stored under a sink in a general household, and can be easily installed by an amateur. For the reasons described above, the present invention has a great effect for environmental purification and has a high industrial value.
