Background

The sewage treatment structure sedimentation tank is a very important ring in a sewage treatment system and is used for removing solid particles, suspended matters, sludge and the like in sewage. The sedimentation tank is divided into a primary sedimentation tank and a secondary sedimentation tank according to the position difference of the sedimentation tank in the sewage treatment system. Wherein the secondary sedimentation tank is mainly used for removing activated sludge after aerobic biological treatment in the sewage.

The settleability of the sludge depends on the aerobic biological treatment at the front end, and sometimes the settleability of the sludge is poor, resulting in floating the sludge on the water surface. In the existing secondary sedimentation tank, when more floating mud is contained in the sewage, the treatment effect on the floating mud is poor, and the floating mud enters the water collecting device along with water flow to influence the sewage treatment effect of a next-stage structure.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, a settling tank water collecting apparatus includes: the pool body 6, a bracket 1, a water passing plate 2, an inclined bottom plate 3, a mudguard 4 and a water outlet pipe interface 5 are arranged in the pool body 6;

the bracket 1 is fixed on a sedimentation tank body 6 and is used for supporting the water passing plate 2, the inclined bottom plate 3 and the mud guard 4;

the inclined bottom plate 3 is connected with the bracket 1 at an inclined included angle; the water passing plate 2 and the mud guard 4 are both vertically arranged annular structures and are connected with the inclined bottom plate 3;

the water outlet pipe joint 5 is positioned at the bottom of the water passing plate 2 and is used for guiding the precipitated water to the next-stage treatment device;
