Description

A New Outlet Weir of Secondary Settling Tank

Technical field:

The utility model relates to the technical field of sewage treatment, in particular to a novel outlet weir of a secondary settling tank.

Background technique:

The main function of the secondary settling tank in the sewage treatment unit is to separate the sludge and clarify the mixed solution. The outlet weir of the traditional secondary settling tank is an overflow weir, and the supernatant liquid overflows from the overflow weir and enters the sump. The suspended substances on the water surface include Floating mud, grease, etc. will enter the sump with the clear liquid, affecting the quality of the effluent, and increasing the treatment load of the subsequent sewage treatment unit.

Utility model content:

In view of the above problems, the technical problem to be solved by this utility model is to provide a new secondary sedimentation tank outlet weir with a simple structure, and the water outlet method is changed to water outlet below the liquid surface, which effectively solves the problem of floating mud, grease and other substances flowing out with the clear liquid.

A new outlet weir of the secondary settling tank of the utility model, which includes an L-shaped water collecting tank, a water collecting tank inlet, a water collecting tank water inlet pipe, and a water collecting tank outlet pipe; The bottom of the L-shaped sump is evenly equipped with several sump inlets, which are respectively connected to the corresponding sump inlet pipes. The sump inlet pipes are set in the clear water layer of the secondary sedimentation tank, and the sump outlet pipes are set One side of the L-shaped sump.

The principle of the utility model is: when the liquid level in the secondary settling tank is higher than the bottom surface of the L-shaped sump, the supernatant liquid in the secondary settling tank enters the L-shaped sump through the water inlet pipe of the sump due to the hydraulic pressure. , the clear water entering the sump enters the next processing unit through the outlet pipe of the sump; when the liquid level of the secondary settling tank is lower than the bottom surface of the L-shaped sump 1, the water inlet pipe of the sump stops entering water.

The utility model has the following beneficial effects: it has a simple structure, effectively solves the problem of floating mud, grease and other substances flowing out with the clear liquid, improves the effluent water quality of the secondary sedimentation tank, and reduces the processing load for the subsequent sewage treatment unit.

Description of drawings:

For ease of illustration, the utility model is described in detail by the following specific implementation and accompanying drawings.

Fig. 1 is the structural representation of the utility model;

In the picture:

L-shaped sump 1, sump water inlet 2, sump inlet pipe 3, sump outlet pipe 4.

Detailed ways:

As shown in Figure 1, this specific embodiment adopts the following technical solutions: it includes an L-shaped sump 1, a sump water inlet 2, a sump inlet pipe 3, and a sump outlet pipe 4; the L-shaped sump 1 is arranged on the secondary sink The water outlet of the pool goes to the pool wall, and the bottom of the L-shaped sump 1 is uniformly equipped with several sump inlets 2, and the several sump inlets 2 are respectively connected with the corresponding sump inlet pipes 3, and the sump inlet pipes 3 are arranged on two sides. In the clear water layer of the settling tank, the sump outlet pipe 4 is arranged on one side of the L-shaped sump 1 .

The principle of this specific embodiment is: when the liquid level in the secondary settling tank is higher than the bottom surface of the L-shaped sump 1, the supernatant liquid in the secondary settling tank enters through the sump inlet pipe 3 through the sump inlet 2 due to the hydraulic pressure. The L-shaped sump 1, the clear water entering the sump enters the next processing unit through the outlet pipe of the sump; when the liquid level of the secondary settling tank is lower than the bottom surface of the L-shaped sump 1, the water inlet pipe 3 of the sump stops water intake.

This specific embodiment has a simple structure, effectively solves the problem of floating mud, grease and other substances flowing out with the clear liquid, improves the effluent water quality of the secondary sedimentation tank, and reduces the treatment load for the subsequent sewage treatment unit.

The basic principles and main features of the utility model and the advantages of the utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model The new model also has various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection required by the utility model is defined by the appended claims and their equivalents.
