れているが、いずれも処理液を沈殿池へ導入し、
沈殿汚泥を返送するのに別個の動力源を必要と
し、その構造も複雑であるという欠点があつた。 Circulating channel type activated sludge treatment equipment has been proposed in the past, which performs aeration treatment while imparting a flow rate to wastewater in a waterway, but in both cases, the treated liquid is introduced into a settling tank,
The disadvantages are that a separate power source is required to return the settled sludge, and its structure is complicated.

There is.
This aeration device 3 can be of the Kessner brush type, the gas-liquid mixture jet aeration type, or the mechanical aeration type, but all of them impart a circulating flow velocity to the wastewater by the aeration force. Therefore, the water level downstream of the aeration device 3 is the highest in the waterway.

よい。 Further, a sedimentation basin 4 is provided in contact with the circulation waterway 2. This sedimentation tank 4 may be located inside or outside the waterway 2, but in this embodiment it is provided in contact with the outer wall 1a of the straight waterway portion. As shown in FIG. 2, on one side wall of the upper part of the sedimentation tank 4, an overflow weir 5 is provided on the outer wall 1a of the circulation waterway 2 and near the highest water position for inflow of sewage using the water level difference. On the other hand, an overflow weir 6 for outflowing the supernatant liquid is provided on the other side wall of the settling tank 4, and is formed so that the supernatant liquid can be discharged to the outside via a discharge pipe 7. Note that the circulation waterway 2 and the sedimentation tank 4 may communicate with each other below the liquid surface.
In addition, the vicinity of the bottom of the sedimentation tank 4 communicates with the waterway 3 as shown in FIG. It is formed so that the sewage can be returned to the waterway 3 by pressure. In addition, the communication part 8 and the inclined part 9 of the sedimentation tank 4 transfer the settled sludge to the waterway 2.
It may have any structure, shape, etc. as long as it can be returned to the manufacturer, and may be formed as shown in FIGS. 4 and 5, for example.

効率的な処理が行なえる。 According to the above configuration, the wastewater in the circulation waterway 2 is aerated while being given a circulation flow rate by the aeration device 3, but a part of the aeration mixture settles from the high water position downstream of the aeration device 3. Flows into pond 4. The aerated liquid mixture that has flowed into the settling tank 4 is subjected to sedimentation treatment, and the supernatant liquid is discharged to the outside via the overflow weir 6 and the discharge pipe 7, while the settled sludge is passed through the communication section 8 as shown in FIG. It is sent back into waterway 2. Therefore, by utilizing the water level difference in the circulation waterway 2 caused by the aeration device 3,
Since the sludge flows into the settling tank 4 and is returned, smooth sludge return can be performed without using any power, and efficient treatment can be performed.
