In order to make the aforementioned and other objects, features and advantages of the invention more comprehensible, preferred embodiments accompanied with figures are described in detail below.

Drawings

Fig. 1 is a front view of the embodiment of the present invention.

Fig. 2 is a schematic plan view of the structure of the embodiment of the present invention.

In the figure: 1-a settling part, 2-a buffer part, 3-a sewage discharge part, 31-a mud scraper, 4-a shunting speed-reducing inclined plate, 5-a settling area, 51-an overflow groove, 6-a water inlet area and 7-a drainage groove.

Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

As shown in fig. 1-2, an inclined high-efficiency sedimentation tank comprises a sedimentation part 1, a buffer part 2 and a sewage discharge part 3.

The included angle between the axis of the settling part 1 and the horizontal plane is 60 degrees; two mutually independent sedimentation zones 5 are arranged in the sedimentation part 1, a water inlet zone 6 is arranged between the adjacent sedimentation zones 5, and the bottom of the water inlet zone 6 is communicated with the bottom of the sedimentation zone 5; a plurality of parallel shunting speed reducing inclined plates 4 are uniformly distributed in the settling zone 5, and the included angle between the shunting speed reducing inclined plates 4 and the horizontal plane is 60 degrees. The water flow direction inclines by 60 degrees, and the inclination of the water flow direction is kept the same as that of the inclined plate, so that the water inlet dead zone and the disturbance to the sludge are reduced.

A water inlet pipe for supplying water to a water inlet area is arranged on one side wall of the settling part 1, so that water can uniformly enter each independent small settling space isolated by the shunting and decelerating inclined plate.

The top of the settling zone 1 is provided with an overflow tank 51, and one end of the overflow tank 51 is communicated with a drainage tank 7, so that the purified water is discharged.
