[0018] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be noted that the terms "center," "up," "down," "left," "right," "vertical," "horizontal," "inside," and "outside" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for the purpose of facilitating the description of the present invention and simplifying the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The present invention will be further described below in conjunction with the accompanying drawings.

[0020] like Figure 1-4The top of the inner tank 2 is detachably mounted on the top of the outer tank 1, and the side wall of the inner tank 2 is provided with an overflow port 4, which is convenient for the solid and liquid waste water in the inner tank 2 to overflow from the overflow port 4. The bottom support 3 is detachably mounted on the outer tank 1, and the bottom support 3 is a convex structure. The inner side wall of the bottom of the inner tank 2 is provided with a sealing ring 16, which is sealed between the inner tank 2 and the bottom support 3. The solid and liquid waste water is poured into the inner tank 2 for sedimentation, and the overflowed solid and liquid waste water flows into the outer tank 1 for auxiliary sedimentation, so that the sludge is settled on the bottom support 3. After the sedimentation is completed, the clarified liquid can be extracted. In order to facilitate the cleaning of the precipitated sludge, the outer tank 1 and the inner tank 2 can be removed from the bottom support 3, which is convenient for cleaning the sludge on the bottom support 3, and at the same time, it is convenient for cleaning the sludge on the inner walls of the outer tank 1 and the inner tank 2.
