Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The embodiment of the utility model provides a:

a novel sedimentation tank for sewage treatment comprises a slow flow tank 1, a transition tank 2 and a gravity tank 3; sewage is through slowing down the flow rate of flow 1 in the pond, prevents through transition pond 2 that the water pressure is too big in the loop, enters into gravity pond 3 after the buffering of transition pond 2, and the velocity of flow in gravity pond 3 is slower, and the place in gravity pond 3 is longer simultaneously, and impurity in the sewage can deposit in gravity pond 3 and take out through the dust absorption pipe.

Perpendicular to in the slow flow pond 1 length direction fixedly connected with a plurality of first stop plates 11 and a plurality of second stop plates 12 in slow flow pond 1, first stop plates 11 and second stop plates 12 are the template of buckling. A gap is arranged between the lower end of the first blocking plate 11 and the slow flow pool 1, the height of the second blocking plate 12 is lower than that of the first blocking plate 11, and the plurality of first blocking plates 11 and the plurality of second blocking plates 12 are arranged in a staggered mode; when sewage is in the process of slowly flowing pool 1, the sewage can only alternately flow in a snake shape between the first blocking plate 11 and the second blocking plate 12 through the blocking of the first blocking plate 11 and the second blocking plate 12, so that the flowing path of the sewage in the slowly flowing pool 1 is lengthened, the effect of slowing down the flow speed of the sewage can be achieved, and the slowly flowing pool 1 is internally parallel to the length direction of the slowly flowing pool 1 and is fixedly connected with a plurality of partition plates 13.
