Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and in particular to a modular reinforced concrete prefabricated assembled sewage treatment device and a system thereof. Background Art

[0002] So far, my country has built and put into operation at least tens of thousands of township sewage treatment plants, most of which are less than 1,000 cubic meters per day and mainly adopt the following two forms:

[0003] 1. Cast-in-place reinforced concrete small sewage treatment station:

[0004] The treatment process mainly adopts a decentralized layout and is divided into pretreatment, biochemical treatment, sedimentation and disinfection. It has many single structures, occupies a large area, has a long construction period, a large amount of on-site work, many types of work, limited site, time-consuming and labor-intensive, etc. In addition, for remote areas such as rural or mountainous areas, the construction cost is higher, and it is difficult to promote traditional sewage treatment systems.

[0005] 2.Steel integrated small sewage treatment device:

[0006] The treatment process mainly adopts an integrated layout. Usually, the service life of a steel integrated small sewage treatment device does not exceed 10 years. After 10 years, most plants and stations using integrated sewage treatment equipment will face a comprehensive reset and update, with high depreciation costs. At the same time, the steel integrated small sewage treatment device needs to be placed on the ground and set up a reinforced concrete foundation. It cannot be directly buried underground, which limits the application scenarios.

[0007] Therefore, in response to the above problems, there is an urgent need for a sewage treatment device that can be prefabricated in advance and quickly assembled. Utility Model Content

By adopting this solution, rapid assembly can be achieved through a number of prefabricated modules, which can not only be promoted in remote areas, but also have unlimited application scenarios.

[0009] The utility model is realized by the following technical solutions:

[0013] C module, the C module is arranged in the U-shaped module assembly and is used to divide the internal space of the U-shaped module assembly.

[0014] Compared with the prior art, conventional small-scale sewage treatment stations in towns and villages adopt cast-in-place reinforced concrete, which occupies a large area, has a long construction period, and a large amount of on-site work. In addition, the construction cost in remote areas such as rural or mountainous areas is higher, the traditional sewage treatment system is difficult to promote, and the service life of steel integrated small-scale sewage treatment devices is short. After 10 years, most plants and stations are faced with comprehensive reset and renewal, high depreciation costs, and cannot be directly buried underground. The application scenarios are limited. The utility model provides a modular reinforced concrete prefabricated assembled sewage treatment device and its system. By adopting this solution, rapid assembly can be achieved through a number of prefabricated modules. It can not only be promoted in remote areas, but also its application scenarios are not restricted. The specific plan includes prefabricated A module, B module and C module, wherein the A module is U-shaped, having a bottom plate and two side edges, and several A modules are spliced ​​in sequence to form a U-shaped module assembly with a certain length, and then the two sides of the U-shaped module assembly are closed by B modules to form a water tank inside, and the C module is arranged inside the U-shaped module assembly, and the interior of the U-shaped module assembly can be divided into anoxic zone, multifunctional zone, sedimentation zone and aerobic zone by one or more C modules to form a multifunctional sewage treatment unit.

[0015] In order to prevent water leakage at the joint between module A and module B, a first joint is formed between the bottom plate and the side of module A and module B, and the first joint has a first groove along its length, and the first groove is filled with a first waterproof component.

Using the above-mentioned force-transmitting water-stop connection node, after calculation and verification, the AB prefabricated unit connection body's anti-overturning, anti-sliding, and node anti-bending and anti-shearing all meet the design requirements.

[0019] In order to prevent water leakage at the joints between adjacent A modules and between A modules and C modules, a second joint is formed between the bottom plates and sides of adjacent A modules and between the bottom plates and sides of A modules and C modules respectively. The second joint has a second groove along its length, and the second groove is filled with a second waterproof component.

After splicing, the two L-shaped grooves can be combined into a second groove, and then a second waterproof component is set at the second groove to achieve a waterproof function.

Secondly, the U-shaped composite rubber waterstop can adapt to possible settlement deformation.

[0022] In order to support the B module and the C module so that they can stand upright on the bottom surface, the outer bottom of the B module and both sides of the bottom of the C module are provided with extension plates extending vertically outward.

[0023] A further solution is that a sewage treatment system includes several modular reinforced concrete prefabricated sewage treatment devices, the inlets of several of the sewage treatment devices are respectively connected in parallel with the sewage inlet pipes, and each has a tailwater discharge outlet.

[0024] Compared with the prior art, the utility model has the following advantages and beneficial effects:
