[0032] Embodiments of the present disclosure provide a sewage treatment system, including: an over-aeration unit 100 connected to a water inlet 200; a sewage treatment unit 300 connected to the over-aeration unit 100, including a plurality of sedimentation tanks 310 connected in sequence and at least one adsorption device 320, the adsorption device 320 being disposed in the sedimentation tank 310, and sewage is pre-sedimented through the over-aeration unit 100 for oxygenation and then successively through the plurality of sedimentation tanks 310 and the adsorption device 320; a dynamic sedimentation unit 400, including a dynamic sedimentation area 410 connected to the sedimentation tank 310 and a settler 420 connected to the dynamic sedimentation area 410, the settler 420 being provided with a drain port 500; and a sewage collection unit 600 connected to the dynamic sedimentation unit 400.
[0033] The following describes the sewage treatment system provided by the embodiments of the present disclosure with reference to the accompanying drawings.
[0034] Figure 1 It is a first structural schematic diagram of some embodiments of the sewage treatment system of the present disclosure. Figure 2 It is a second structural schematic diagram of some embodiments of the sewage treatment system of the present disclosure. As Figure 1 and Figure 2 shown, the arrow indicates the sewage flow direction. The sewage treatment system is disposed beside a river. After the sewage enters the water inlet 200, it successively passes through the over-aeration unit 100, the sewage treatment unit 300, the dynamic sedimentation area 410, and the settler 420, and then is discharged into the river from the drain port 500.
[0035] Specifically, the over-aeration unit 100 is used to introduce oxygen into the sewage, enabling the sewage to contact with air for oxygenation, accelerating the transfer of oxygen into the sewage by agitation, preventing suspended substances in the sewage from sinking, strengthening the contact between organic matters and dissolved oxygen in the sewage, and accelerating the dissolution rate of pollutants in the sewage. The sewage treatment unit 300 utilizes the fluidity of the sewage to precipitate pollutants in the sewage and uses the adsorption effect of the adsorption device 320 to remove organic matters in the sewage, playing a role in preliminary water purification; further, the sewage treatment unit 300 includes at least one sedimentation tank 310. The dynamic sedimentation area 410 and the settler 420 further precipitate pollutants in the sewage, enabling the treated sewage to reach the discharge standard and then be discharged through the drain port 500. Among them, the precipitated sludge and pollutants flow into the sewage collection unit 600 successively through the sewage treatment unit 300 and the dynamic sedimentation area 410 under the scouring of the sewage. The sewage collection unit 600 is used to collect the precipitated pollutants and is regularly cleaned by staff.
[0036] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:
[0037] By setting a sedimentation tank, an adsorption device 320, a dynamic sedimentation area 410, and a settler 420, the sewage is sedimented multiple times by utilizing the fluidity of the sewage, which has the advantages of simple structure, low energy consumption, and thorough sewage treatment. It solves the problems of incomplete sewage treatment and high energy consumption in the prior art, and achieves the technical effect of sewage treatment under the condition of low energy consumption.
[0038] Figure 3 This is a partial structural schematic diagram of some embodiments of the sewage treatment unit 300 of the sewage treatment system of the present disclosure. As Figure 3 shown, the arrow indicates the sewage flow direction. The sewage treatment unit 300 further includes: a water separation wall 330 disposed between two adjacent sedimentation tanks 310. An outlet 340 is formed between the water separation wall 330 and the sedimentation tank 310. The two adjacent outlets 340 are respectively located at the high and low positions of the water level.
[0039] In this embodiment, the water separation wall 330 is mainly used to form an outlet 340 with the sedimentation tank, so that the two adjacent outlets 340 are respectively located at the high water level and the low water level of the sedimentation tank, enhancing the fluidity of the sewage, further improving the sedimentation efficiency, and increasing the sewage treatment effect. Further, the adsorption device 320 is fixed on the water separation wall 330 by a buckle and can be replaced regularly to ensure the stability of the adsorption effect. Each adsorption device 320 includes a partition plate for restricting the flow direction of the sewage, so that the sewage can only flow into the next sedimentation tank 310 from the adsorption device 320, ensuring the sewage treatment effect.
[0040] As Figure 3 shown, the sewage treatment unit 300 further includes: a sieve plate 350. Along the sewage flow direction, the sieve plate 350 is disposed on the adsorption device 320.
[0041] In some embodiments, the adsorption device 320 is disposed at the outlet 340 or other positions of the sedimentation tank 310. One adsorption device can be provided, or multiple adsorption devices can be provided. The sieve plate 350 is disposed on the adsorption device 320 along the sewage flow direction, ensuring the blocking rate of pollutants is improved while the sewage flows out, and improving the sewage treatment effect.
[0042] In some embodiments, the opening rate of the sieve plate 350 is 26%.
[0043] In this embodiment, setting the opening rate of the sieve plate 350 to 26% makes the blocking rate of sludge and suspended matter optimal, which is beneficial to improving the water quality.
[0044] Figure 4 This is a structural schematic diagram of some embodiments of the dynamic sedimentation unit 400 of the sewage treatment system of the present disclosure. As Figure 4As shown, a plurality of folded plates 421 are arranged in the middle of the settler 420, and a plurality of through holes for sewage to flow in are arranged between the folded plates 421 and the dynamic settling area 410.
[0045] In this embodiment, the arrow indicates the sewage flow direction. Sewage can enter the folded plate 421 through the through holes. The folded plate 421 is used to block pollutants, further improving the sewage treatment efficiency. Further, the shape of the folded plate 421 can be set as a V shape, an S shape, etc.
[0046] Figure 5 For Figure 4 the enlarged view of part A, which shows the structural schematic diagram of some embodiments of the folded plate 421 of the sewage treatment system of the present disclosure. As Figure 5 shown, an opening is provided on the folded plate 421. On the one hand, the opening can improve the fluidity of sewage and further enhance the sewage treatment speed; on the other hand, the opening can play a role in blocking the passage of pollutants.
[0047] In some embodiments, the opening ratio of the folded plate 421 is 12% - 16%.
[0048] In this embodiment, setting the opening ratio to 12% - 16% can effectively block the pollutants in the sewage while ensuring the improvement of the water flow speed.
[0049] As Figure 4 and Figure 5 shown, a water inlet 430 for sewage to flow in is provided below the folded plate 421, and a drain port 500 is opened above the folded plate 421.
[0050] In this embodiment, sewage can also flow into the folded plate 421 through the water inlet 430 below the folded plate 421 and then be discharged through the drain port 500. The resistance of the folded plate 421 is used to further precipitate the pollutants in the water, ensuring the sewage treatment efficiency.
[0051] As Figures 1-5 shown, an opening communicating with the dynamic settling area 410 is opened at the low water level of the sedimentation tank 310, and sewage flows into the dynamic settling area 410 through the opening.
[0052] In this embodiment, sewage flows into the dynamic settling area 410 from the low water level of the sedimentation tank 310, ensuring that after being treated by the dynamic settling area 410, it can pass through the through holes and the water inlet 430 and be further treated by the folded plate 421, ensuring the sewage treatment effect.
[0053] Figure 6 For Figure 6As shown, the water inlet 200 is opened at the low water level of the sedimentation tank 310, and the over-aeration unit 100 is arranged in the sedimentation tank 310.
[0054] In this embodiment, the sewage enters the over-aeration unit 100 through the water inlet 200, and after being oxygenated, it flows into the sewage treatment unit 300. The over-aeration unit 100 is arranged in the sedimentation tank 310 to continuously oxygenate the sewage, ensuring the oxygen content rate of the sewage and accelerating the dissolution rate of pollutants in the sewage.
