Alternatively, the cross section of the first cavity may be rectangular, such as square or rectangle, and the cross section of the second cavity 102 may be trapezoid, wherein the longer lower base of the trapezoid may meet the side of the rectangle of the cross section of the first cavity 101. As shown in fig. 1, it can be understood that the second cavity 102 of the embodiment of the present invention may have a tapered structure. Since the second chamber 102, i.e. the inner wall 3 of the cone structure, is obliquely arranged, the obliquely arranged inner wall can be used for settling sediment in the mixed liquor, for example, the sediment can be sludge.
The sedimentation partition plate 6 is of a V-shaped structure, and the opening direction of the sedimentation partition plate is opposite to the opening direction of the second cavity 102; a first opening is formed between the end 601 of the settling baffle 6 and the inner wall 3 of the second chamber 102.
Specifically, in the embodiment of the present invention, the number of the settling partitions 6 may be two, and two settling partitions 6 may be symmetrically arranged with an axis inclined to the vertical direction, so that the two settling partitions 6 together form a V-shaped structure, and the opening direction of the V-shaped structure is opposite to the opening direction of the conical structure of the second cavity 102. Fig. 2 is a cross-sectional view of an alternative configuration of a sediment separator according to an embodiment of the present invention, and the specific cross-sectional line can be seen from the cross-sectional line a-a shown in fig. 1. Through two sedimentation partition plates forming a V-shaped structure, the interior of a cavity (the cavity comprises a first cavity 101 and a second cavity 102) of the sediment separator can be divided into a first sedimentation zone 7, a second sedimentation zone 8 and a third sedimentation zone 9. Since the sedimentation partition plates 6 are disposed obliquely to the vertical direction, sludge in the mixed liquid is sedimented in the three sedimentation zones by the obliquely disposed sedimentation partition plates 6 and the obliquely disposed inner wall 3 of the second chamber 102.
The end 601 of the settling baffle 6 may extend into the second chamber 102 and be kept at a distance from the inner wall 3 of the second chamber 102, forming a first opening; through the first opening, sludge settled on the settling partition 6 can flow out along the first opening, so that excessive sludge can not be accumulated on the settling partition 6 due to long-term settlement. And the mixed liquor in the three sedimentation zones can circulate through the first opening. Optionally, the apertures of the two first openings formed by the two settling baffles 6 and the inner wall 3 of the second cavity 102 may be equal, so that the flow rates of the mixed liquid in the first settling zone 7 and the second settling zone 8 may be equalized.
In the embodiment of the present invention, the casing 100 includes a first cavity 101 and a second cavity 102 that are communicated with each other, and a cross section of the second cavity 102 is a trapezoidal structure; the sedimentation partition plate 6 is of a V-shaped structure, and the opening direction of the sedimentation partition plate is opposite to the opening direction of the second cavity 102; a first opening is formed between the end 601 of the settling baffle 6 and the inner wall 3 of the second cavity 102; the precipitation partition plate with the V-shaped structure is used for increasing the precipitation area of the precipitate and improving the separation efficiency of the precipitate; simultaneously, the settled sludge flows out through the first opening, so that the problems of sludge deposition, blockage, algae growth and the like are avoided.
In another embodiment of the present invention, the first cavity 101 comprises two oppositely disposed baffles 2; the guide plate 2 is provided with a through hole 21, and the through hole 21 is communicated with the first cavity 101 through the guide pipe 13.
In particular, as shown in fig. 1 and fig. 2, the baffle 2 may be a side wall of the first cavity 101. The guide plate 2 is provided with a through hole 21, and in the actual use process, when the sediment separator is arranged in the aeration tank, the mixed liquid passes through the through hole 21 and enters the cavity of the sediment separator (the cavity comprises a first cavity 101 and a second cavity 102) along the guide pipe 13 so as to separate the sediment.
As shown in fig. 2, in another embodiment of the present invention, the draft tube 13 may include a curved portion 130 and a linear portion 131, the curved portion 130 and the linear portion 131 communicating with each other;
the curved portion 130 has a cross-sectional diameter greater than that of the linear portion 131.

In another embodiment of the present invention, the first end of the second cavity 102 is provided with a sludge outlet 31; an air blocking component 5 is arranged at the opening of the sludge outlet 31, and a sludge backflow seam 51 is formed between the sludge outlet 31 and the air blocking component 5.
In an embodiment of the present invention, the first end of the second cavity 102 may be a bottom end of the second cavity 102. In the embodiment of the present invention, one end of the V-shaped structure formed by the settling baffles 6, which is opposite to the opening direction, is a bottom end of the second cavity 102. The sludge outlet 31 is used for discharging sediment (e.g., sludge).

the opening adjustment device 16 includes two blocking members 161, and the two blocking members 161 are rotatably connected to each other by an adjustment shaft 160.
Specifically, as shown in fig. 3, the aperture adjusting device may be used to adjust the aperture of the second opening, so that the amount of liquid flowing through the second opening may be controlled by adjusting the aperture of the second opening. Specifically, the aperture of the second opening can be adjusted by adjusting the angles of the two blocking members 161.
