が充分に行なわれる。Since the grease trap 1 according to the present invention has the above-described structure, the raw water flowing into the filtration network 9 from the inflow port 6a flows out while leaving large debris, and the raw water flows out of the microorganism filtration body 11. Organic substances are decomposed or purified by the aerobic microorganisms that diffuse or adhere to the filter body 11 itself, and oxygen is supplied by bubbles ejected from the air diffuser 13, and the oxygen is supplied to the filter body 11. It flows to the oil / fat separation chamber 7 through the opening 10 a of the body holding member 10.
At this time, buoyant contaminants such as fats and oils and scum contained in the raw water abut against the baffle plate 22 and are guided upward to float, and are prevented from being transferred downstream by the separation float 19. Further, the sediment having a large specific gravity contained in the raw water is advected by the air diffuser 13 and is moved from the raw water inflow chamber 6 to the oil and fat separation chamber 7
After passing through the opening 5a of the second partition 5 to the drainage chamber 8, it is naturally lowered by the inclined plate 21 installed at the bottom of this chamber and is concentrated on the inclined lower part. The first pneumatic pump 14 sucks oils and fats and scum from the water suction port 14a, which is constituted by the float 17 and the flexible tube 16 and is always positioned on the water surface, and is discharged from the water discharge port 14b positioned on the filtration net 9. Discharge. Further, since the water suction port 15a of the second pneumatic pump 15 is located below the inclined plate 21, the deposited sediment is sucked and the first pneumatic pump 1
Similarly to 4, the water is discharged from the water discharge port 15b located on the filtration net 9. Thus, the waste in the raw water circulates and the microorganism filter 1
Since it is repeatedly contacted with 1, the purification treatment by the biological oxidizing action is sufficiently performed.
