[0036] Reference Figures 1-6 The utility model discloses an embodiment shows a kind of sewage treatment integrated device with wide application range, including rack 1, primary filtration unit 2, aeration unit 3 and sedimentation unit 4, the primary filtration unit 2, aeration unit 3 and sedimentation unit 4 All are set on the rack 1, the primary filtration unit 2 and aeration unit 3 are distributed transversely and are set above the sedimentation unit 4;The primary filtration unit 2 includes primary filter tank 21, and the primary filter tank 21 is equipped with filter grid plate 22, and the primary filter tank 21 is provided with water inlet pipe 23;The aeration unit 3 includes aeration tank 31, and aeration tank 31 is equipped with aeration mechanism 32, and the aeration tank 31 is connected with the primary filter tank 21 by first pipeline 24;The sedimentation unit 4 includes sedimentation tank 41, and the sedimentation tank 41 is connected with the aeration tank 31 by second pipeline 33, and the sedimentation tank 41 is provided with water outlet pipe 44;Wherein, fluid in the aeration unit 3 flows into the sedimentation tank 41 along the second pipeline 33 under the action of gravity, and the second pipeline 33 is equipped with stop valve 331.

[0037] Specifically, sewage enters the primary filter tank 21 through the water inlet pipe 23, and large-particle suspended matter such as branches, plastic bags, paper, plastic, etc. in the sewage is removed through the filter grid plate 22 to prevent it from entering the subsequent processing unit and causing blockage. Then the sewage enters the aeration tank 31 through the first pipeline 24. In the aeration tank 31, aerobic microorganisms utilize dissolved oxygen as an electron acceptor to oxidize and decompose organic matter in the sewage into carbon dioxide, water and biomass, thereby purifying the sewage. Then the sewage enters the sedimentation tank 41 through the second pipeline 33. The mixed liquid treated by the aeration tank 31 still contains a certain amount of suspended solids (mainly activated sludge) and dissolved substances. The sedimentation tank 41 separates these suspended solids from the mixed liquid by gravity settling to form supernatant and sludge layer. The supernatant is discharged through the water outlet pipe 44. In this way, the sewage treatment is realized, and the sewage meets the discharge requirements.

[0038] In the sewage treatment integrated device, the primary filtration unit 2, the aeration unit 3 and the sedimentation unit 4 are in a double-layer distribution structure on the rack 1. The various processing units are compactly integrated on the rack 1, greatly reducing the floor area of the device, so that the sewage treatment integrated device can be easily deployed in areas where land resources are scarce, improving its application range and flexibility. In addition, by designing the height difference between the aeration unit 3 and the sedimentation unit 4, the fluid can flow naturally between the aeration unit 3 and the sedimentation unit 4 by gravity, without the need for additional pump driving. This design reduces the number and complexity of equipment components, reducing manufacturing costs. At the same time, since the use of pumps is reduced, the energy consumption and maintenance costs during operation are also reduced.

[0039] In the above scheme, when the stop valve 331 is closed, the water in the aeration tank 31 cannot flow into the sedimentation tank 41. Thus, the aeration reaction time of the sewage in the aeration tank 31 can be adjusted.

[0040] Specifically, as shown in Figure 2 and Figure 4 , the filter grid plate 22 divides the primary filter tank 21 into a first chamber 211 and a second chamber 212. The first chamber 211 is connected to the water inlet pipe 23, and the second chamber 212 is connected to the first end of the first pipeline 24. A first pump body (not marked in the figure) is provided on the first pipeline 24. The second end of the first pipeline 24 is connected to the aeration tank 31. The water in the second chamber 212 is pumped into the aeration tank 31 by the first pump body.

[0041] In some embodiments, as shown in Figure 2 , Figure 5 and Figure 6As shown, the aeration mechanism 32 comprises a mechanical aeration assembly 322 and a mechanical aeration assembly 322; the mechanical aeration assembly 321 comprises a jet aerator arranged at the bottom surface of the aeration tank 31 and an air compressor for providing air for the jet aerator; the mechanical aeration assembly 322 comprises a stirrer 3221 arranged in the aeration tank 31 and a driving motor 3222 for driving the stirrer 3221 to rotate in the aeration tank 31.

[0042] The air compressor delivers air to the jet aerator through a pipeline to form air bubbles in the aeration tank 31 to increase the contact area between the sewage and oxygen, improve the oxygen dissolution efficiency, and further improve the oxidation and decomposition efficiency of the organic matter in the sewage by the aerobic microorganisms. In addition, the mechanical aeration assembly 322 in the embodiment drives the stirrer 3221 to agitate the sewage in the aeration tank 31 through the driving motor 3222 to improve the efficiency of oxygen in the air dissolving into water; the cooperation of the mechanical aeration assembly 321 and the mechanical aeration assembly 322 improves the water purification efficiency of the aeration unit 3.

[0043] Of course, in other embodiments, only the mechanical aeration assembly 321 or the mechanical aeration assembly 322 can be arranged in the aeration tank 31.

[0044] The above scheme is specific, for example, Figure 6 As shown, the stirrer 3221 comprises a rotating shaft 32211 and a paddle 32212 arranged on the rotating shaft 32211, the rotating shaft 32211 is rotatably connected with the aeration tank 31, and the rotating shaft 32211 and the driving motor 3222 are chain driven.

[0045] In some embodiments, in order to separate the supernatant and the sludge layer in the sedimentation tank 41, as shown in Figure 2 and Figure 3 As shown, the upper part of the inner side wall of the sedimentation tank 41 is provided with a sedimentation partition plate 42, the sedimentation partition plate 42 and the inner side wall of the sedimentation tank 41 form a water outlet groove 43, and the water outlet pipe 44 is connected to the water outlet groove 43. When the liquid level of the supernatant is higher than the sedimentation partition plate 42, the supernatant can flow into the water outlet groove 43 and be discharged from the water outlet pipe 44.

[0046] The above scheme is specific, in order to reduce the influence of the water inlet of the second pipeline 33 on the sedimentation environment in the sedimentation tank 41, as shown in Figure 2 and Figure 3As shown, the sedimentation tank 41 is provided with a vertically arranged guide pipe 45, the guide pipe 45 is connected with the sedimentation tank 41 through a connecting frame 46, and the upper end of the guide pipe 45 is connected with the second pipeline 33; in the working state, the lower end of the guide pipe 45 is lower than the liquid level in the sedimentation tank 41. In this way, when the sewage in the aeration tank 31 flows into the sedimentation tank 41 from the second pipeline 33, the disturbance of the water inlet of the second pipeline 33 to the sedimentation tank 41 can be reduced by the guide pipe 45, thereby reducing the influence on sludge sedimentation and improving the sedimentation efficiency.

[0047] The above scheme is specifically as follows: Figure 2 and Figure 3 The bottom of the sedimentation tank 41 is in an inverted conical structure, and the bottom of the sedimentation tank 41 is connected with a sludge outlet pipe 47. The sludge outlet pipe 47 can be connected with an external sludge treatment device (such as a sludge filter press) to remove the sludge in the sedimentation tank 41.

[0048] In the above embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0049] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
