Description

Integrated water outlet collecting tank for high-density sedimentation tank and high-density sedimentation tank

Technical Field

The utility model relates to an integrated water outlet collecting tank for a high-density sedimentation tank and the high-density sedimentation tank.

Background

The high-density sedimentation tank is an efficient coagulating sedimentation process integrating coagulation, flocculation, inclined tube clarification and sludge concentration. The whole high-density sedimentation tank body comprises a coagulation reaction zone, a flocculation reaction zone, an inclined tube clarification zone and a sludge concentration reflux zone. The water inlet of the high-density sedimentation tank, the coagulant and the flocculant are added to carry out coagulation and flocculation reactions in a coagulation reaction zone and a flocculation reaction zone, so that large, compact and uniform alum blossom is formed. The alum blossom enters into a tube chute clarification area for mud-water separation. The inclined tube clarifying area is provided with an inclined tube and a water outlet water collecting tank, the mud-water mixture is separated in the inclined tube area, and then the water is discharged after being collected by the water outlet water collecting tank. The effluent water collecting tank is very important workpiece static equipment in a high-density sedimentation tank. The water collecting tank and the notch weir on the water collecting tank not only control the liquid level elevation of the high-density sedimentation tank, but also prevent the bias flow phenomenon in the inclined tube clarification area, and ensure the uniform and stable water flow, thereby ensuring the sedimentation effect. At present, the water outlet water collecting tank is designed in a split mode, namely, the water outlet water collecting tank and the water outlet notch weir are manufactured separately, the water outlet notch weir is arranged in the upper area on two sides of the water outlet water collecting tank, and the water outlet notch weir is fixed by bolts in the middle of the water outlet water collecting tank and the water outlet notch weir.

The design of the water outlet and collecting tank has the following problems:

the water outlet collecting tank is integrally arranged in the treated water, and the bolts and nuts connected with the water outlet notch weir and the water outlet collecting tank are also all immersed in the treated water. Most of the treated water is sewage, has complex components and has certain corrosiveness. After long-term running, the bolts and nuts used for fixing are at risk of corrosion and rust, and the rusted bolts and nuts are easy to loosen, so that gaps are formed between the water outlet notch weir and the water outlet water collecting tank or fiber substances are blocked, treated water flows into the water outlet water collecting tank from the gaps, drift phenomenon occurs in a clarification area of a high-density pool, and precipitation effect is influenced;

the manufacturing, processing and installation of the split-type water outlet collecting tank are complex. Firstly, the water collecting tank and the notch weir are two parts, and the two parts need to be processed and manufactured respectively. After the processing is finished, the two are fixed by using bolts and nuts, then the water outlet water collecting tank can be integrally installed, and the manufacturing and installation periods are long. The complexity of fabrication and processing necessarily results in increased overall equipment costs.

Accordingly, there is a need to provide an improved effluent header tank that overcomes at least one of the above problems.

TABLE 1

The recess is preferably a machine punched hole in the same horizontal position. The number of notches depends on the rising flow rate of the settling zone of the high-density settling tank. The rising flow rate is denoted by UT, for example, at UT <18m/h, a plurality of notches may be provided at 8 per meter; at 18< UT <35m/h, the plurality of notches may be provided at 12 per meter.

The size of the notch is determined according to the water outlet amount of the single notch, and the notch is generally 50mm wide and 70mm high, and the water level on the notch is lower than the height of the notch by 70mm in the practical use process. The water level elevation at the water outlet side of the water collecting tank is a control elevation, the water outlet notch elevation is given according to the control elevation, and the water outlet notch elevation is generally higher than the water level elevation in the water collecting tank by more than 50 mm.

The dividing belt 2 is arranged at the lower part of the water outlet water collecting tank and is used for dividing the sedimentation zone of the high-density sedimentation tank into a plurality of areas so as to ensure that water flows in each area are stably collected by the water outlet water collecting tank corresponding to each area and are not mutually interfered. One end of the separation belt 2 is arranged at the bottom of the water outlet collecting tank, and the other end is arranged at a sedimentation area of the high-density sedimentation tank. The separator is formed of rubber and has a thickness of about 5 mm. The other end of the separation belt is positioned 30mm below the upper top surface of the inclined tube of the sedimentation zone.
