Description

An embedded high-efficiency sedimentation tank device

technical field

The utility model relates to the technical field of sewage treatment equipment, in particular to an embedded high-efficiency sedimentation tank device.

Background technique

Sedimentation tank is a commonly used treatment structure for separating suspended solids. According to different process layouts, it can be divided into primary settling tanks and secondary settling tanks. Among them, the main function of the secondary settling tank is to separate muddy water, clarify the mixed solution, concentrate and return the activated sludge. It is generally located behind the biological treatment structure and is an important part of the activated sludge system.

For rural areas with a small amount of sewage treatment, the secondary settling tank should be equipped, and the pool type should be a vertical flow or inclined plate settling tank. However, both the vertical flow sedimentation tank and the inclined plate sedimentation tank have their disadvantages: (1) The water in the vertical flow sedimentation tank enters the tank from top to bottom through the central guide pipe set in the center of the tank, and the bottom of the pipe Umbrella-shaped baffles are set to distribute the sewage evenly in the pool and then rise slowly along the entire cross-section. However, due to the deep depth of the vertical flow sedimentation tank, construction is difficult, and in order to make the water distribution in the pool even, the pool diameter should not be too large. It is beneficial to the maintenance and replacement of technical personnel in the later period; (2) The buffer capacity of the sloping plate sedimentation tank is relatively short due to the short residence time. It is difficult to maintain and manage.

The integrated sedimentation tanks currently in the market generally use a single type of sedimentation tank, the mud-water separation effect is not high, the effluent water quality is unstable, and due to the limited size of the tank body, once a problem occurs during operation, it is relatively difficult to repair or replace.

3. Beneficial effect

Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

(1) The utility model adopts a modular combination installation method, and the core components are processed separately to form an independent module unit, and each module unit is spliced and assembled to form a complete device, which reduces the labor intensity of the technicians. When there is a problem, under the condition of ensuring the normal operation of the equipment, it is only necessary to remove the internally damaged unit for repair or replacement, which not only facilitates later maintenance and management, but also saves costs.

(2) The utility model combines the vertical flow sedimentation tank and the inclined plate sedimentation tank. The sewage first enters the vertical flow sedimentation tank through the central diversion pipe, and the water flow distributed to the surroundings after being blocked by the reflecting plate enters the inclined plate sedimentation tank, reducing the The load of the inclined plate sedimentation tank is reduced, the area of the sedimentation zone is also greatly increased, and the separation effect and processing capacity of the sedimentation tank are greatly improved.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Example 1

It can be seen from Fig. 1 that a kind of embedded high-efficiency sedimentation tank device of the present embodiment includes a water inlet pipe 1 and a center guide pipe 2, the material of the water inlet pipe 1 is steel, the water inlet pipe 1 is arranged on the shell 12, and the center guide pipe 2 The flow pipe 2 is vertically welded on the water inlet pipe 1, and the lower end of the central diversion pipe 2 is equipped with a reflector 3. The above-mentioned central diversion pipe 2, water inlet pipe 1 and reflector 3 are a complete module unit, which can be directly embedded in the equipment , It is very convenient to assemble and disassemble, which reduces the workload of later maintenance and management. A baffle 4 is installed on the side of the central guide pipe 2, and a support plate 10 is welded on the side of the above-mentioned baffle 4, and a mud bucket 8 and a mud discharge pipe 9 are arranged below the support plate 10, and the mud bucket 8 and the mud discharge pipe 9 connected. There are 20 inclined plates 5 obliquely fixed on the above-mentioned support plate 10, and the inclined plates 5 can be called out of the equipment at any time for cleaning and replacement. The top of the inclined plates 5 is provided with an outlet weir groove 6, and the above-mentioned outlet weir groove 6 is fixed on the On the outlet weir groove support plate, the outlet water weir groove 6 and the outlet water weir groove support plate are another complete module unit embedded in the equipment, and can be repaired and replaced at any time. The side of the outlet weir groove 6 is connected with an outlet pipe 7; the top cover 13 is installed on the upper part of the casing 12, and the top cover 13 is hingedly connected with the casing 12. The top cover 13 and the casing 12 are made of carbon steel, multi-layer anti-corrosion, and The facade is coated with metallic paint, which increases the service life of the equipment.

The working principle and process of this embodiment: sewage enters the central diversion pipe 2 from the water inlet pipe 1, and the lower opening of the central diversion pipe 2 is provided with a reflector 3. Under the obstruction of the reflector 3, the water flow changes from vertical downward to vertical The reflection plate 3 is distributed around, the sewage on the left is evenly distributed in the vertical flow sedimentation tank from bottom to top, and the sewage on the right flows slowly into the inclined plate 5 from the bottom of the vertical flow sedimentation tank under the action of the baffle plate 4 , the clarified supernatant overflows from the weir of the outlet weir groove 6 arranged on the top of the pool wall, flows out of the pool through the outlet pipe 7, and the separated sludge settles into the mud bucket 8, and part of the sludge is used for backflow , the remaining sludge is discharged from the pool body. The double combination of the vertical flow sedimentation tank and the inclined plate sedimentation tank makes the sewage pass through the vertical flow sedimentation tank first, and after a part of the sinkable particles in the sewage are removed, it flows into the inclined plate evenly, which greatly reduces the load on the inclined plate. It makes up for the insufficiency of the buffer capacity of the inclined plate sedimentation tank. In addition, the area of the sedimentation area is enlarged, the separation effect is more significant, and the effluent water quality is more stable.
