Problems solved by technology

[0006] However, the technical solutions reported in the above patents and the filtering devices disclosed in the prior art all have poor filtering effects. During the filtering process, as the filtration time increases, the purification effect of sewage gradually decreases. The main reason is that the filtering devices disclosed in the prior art Hierarchical filtering is not possible

Embodiment 1

[0053] Such as Figure 1-8As shown, a multi-stage filter device for urban sewage treatment includes a primary water storage filter tank 5, and the primary water storage filter tank 5 is connected to several secondary filter assemblies 3, and the secondary filter assembly 3 is connected to There are several tertiary filter assemblies 4 . Through the first-stage water storage filter tank 5, the second-stage filter assembly 3, and the third-stage filter assembly 4, multi-stage filtration of sewage is realized, and the effect of sewage filtration is improved.

[0054] The top of the primary water storage filter tank 5 is communicated with a water inlet flange 51 . The first-stage water storage filter tank 5 preliminarily filters the sewage and then passes through several second-stage filter components for 3-layer filtration.

[0055] The specific structure of the secondary filter assembly 3 is as follows:

[0056] Each secondary filter assembly 3 includes a cylindrical filter c...

Embodiment 2

[0069] Such as Figure 1-8 As shown, in this embodiment, on the basis of the structure of Embodiment 1, in order to support the above-mentioned filter cartridge 31 and filter membrane tube 41, a support device with the following structural design is adopted:

[0070] The multi-stage filter device for urban sewage treatment also includes a support plate 2 supporting the filter cartridge 31 and the filter membrane tube 41, and the top of the support plate 2 is provided with an arc-shaped groove 22; the filter cartridge 31 and the filter membrane tube 41 are equipped with In the arc-shaped groove 22.

[0071] At the same time, a base plate 1 is provided at the bottom of the support plate 2 , and the front and rear side walls of the support plate 2 are fixedly connected to the base plate 1 through connecting columns 21 .

[0072] The advantages of adopting the above-mentioned device parts design are:

[0073] By designing the support plate 2, the top of the support plate 2 is pr...

Embodiment 3

[0075] Such as Figure 1-8 As shown, in this embodiment, based on the structural contact of Embodiment 2, in order to realize preliminary filtration of sewage in the primary water storage filter tank 5 , a primary filter component 52 is fixedly connected in the primary water storage filter tank 5 . The sewage is preliminarily filtered through the primary filter component 52 .

[0076] The specific structure of the primary filter part 52 is as follows:

[0077] The primary filter component 52 includes two connecting rings 521 arranged at intervals up and down; the connecting rings 521 are fixedly connected to the inner sidewall of the primary water storage filter tank 5; the bottoms of the connecting rings 521 are fixedly connected with several Filter cage part 522 .

[0078] Sewage enters the filter cage part 522 to be adsorbed and filtered. Specifically, the filter cage parts 522 each include a top fixing plate 5221 , and the filter cage parts 522 also include a bottom fil...

Abstract

The invention discloses a multistage filtering device for municipal sewage treatment. The multistage filtering device comprises a first-stage water storage filtering tank, wherein the first-stage water storage filtering tank communicates with a plurality of second-stage filtering assemblies, and the second-stage filtering assemblies communicate with a plurality of third-stage filtering assemblies;each second-stage filtering assembly comprises a filter cartridge, and adjacent filter cartridges communicate with each other in series through first pipelines; each third-stage filtering assembly comprises a filtering membrane pipe, and adjacent filtering membrane pipes communicate with each other in series through second pipelines; the filter cartridges communicate with the filter membrane pipes through the first pipelines; and a filter cartridge cavity is formed in each filter cartridge, and a plurality of filter components which are arranged at intervals along a front-to-back direction and are used for filtering are arranged in and fixedly connected with the filter cartridge cavity. Graded filtration is achieved through the design of the components of the device, filtering and purifying efficiency is high, filtering time is effectively prolonged through graded filtration, and filtering effect is improved.

Description

technical field [0001] The invention relates to the field of urban sewage treatment devices, in particular to a multi-stage filter device for urban sewage treatment. Background technique [0002] With the development of cities, the increase of urban population, and the acceleration of industrial production, a large amount of urban sewage is produced in cities every day. After urban sewage is purified and treated, it becomes clean water that can be recycled. [0003] Studies have shown that urban sewage generally contains organic pollutants, including carbohydrates, proteins, amino acids, fatty acids, oils, esters and other substances. Urban sewage contains a large amount of suspended solids and sediments. Therefore, in the purification of the above-mentioned urban sewage, it is necessary to filter and purify the above-mentioned suspended solids and sediments. [0004] Based on the importance of environmental protection treatment of urban sewage, there have been many report...
