Description

Technical Field

[0001] The invention belongs to the technical field of water environment treatment, and in particular relates to a sewage ecological purification system for water environment treatment. Background Art

[0003] Lack of oxygen in water bodies is the root cause of black and smelly water bodies. Therefore, when treating urban black and smelly water bodies, it is necessary to artificially oxygenate the water bodies, that is, to add oxygen to the water bodies, increase the DO content of the water bodies, and increase the metabolic activity of aquatic organisms, especially microorganisms, so as to increase the degradation rate of organic pollutants in the water bodies and achieve the purpose of improving water quality. When performing oxygenation treatment on water bodies, the artificial oxygenation equipment in the prior art is not suitable for densely populated areas, such as moats, wetland parks and other urban landscape areas. This is mainly because the oxygenation equipment often produces odor when oxygenating the water bodies, which then spreads to the air near the water body, causing serious discomfort to people nearby.

[0004] For example, the Chinese invention patent with publication number CN110589974B discloses a system and method for treating black and smelly rivers in cities. The treatment system uses an air pump to input air above the liquid level from the air pipe to the bottom of the river to aerate the water. The aeration will disturb the bottom mud at the bottom of the river, which will cause the organic matter and sulfide accumulated in the mud to rise to the surface of the water and emit a foul odor. In addition, since the organic matter in the water is in an anaerobic state before oxygenation, these organic matter will be oxidized after oxygenation, and foul-smelling gases such as hydrogen sulfide and ammonia may be released in the process. The odor then spreads to the air near the water, affecting people nearby. For another example, the Chinese invention patent with publication number CN113354089B discloses a device and method for treating black and smelly water bodies in rural areas. The device uses an aeration component to stir the flow of water, increase the contact area between the water and oxygen in the air, and increase the dissolved oxygen and redox potential in the water. However, the device still has the above-mentioned problems that organic matter and sulfide accumulated in the bottom mud will emit a foul odor after rising to the water surface, and organic matter in the water will release foul-smelling gases after oxygenation, which will then spread to the nearby air and affect people. Summary of the invention

[0005] In view of the above-mentioned problems, the purpose of the present invention is to provide a sewage ecological purification system for water environment management, which can effectively prevent the foul odor generated when oxygenating the water body from spreading to the air near the water body.

[0039] It should be noted that the circuit connections involved in the present invention all adopt conventional circuit connection methods and do not involve any innovation.

[0040] Example 1

[0041] like Figure 1 The sewage ecological purification system for water environment treatment shown in the figure includes a floating body 1, an aeration component 2, a first mounting frame 3, a cover body 4, a second mounting frame 5 and a processing component 6.

[0042] The floating body seat 1 is composed of a plurality of sub-floating bodies 10 and is an annular structure; Figure 1 , Figure 2As shown, the aeration assembly 2 is mounted on the sub-floating body 10 via a first mounting frame 3, and the first mounting frame 3 is located in the inner ring hollow area of ​​the annular structure. The aeration assembly 2 includes an air supply member 21, a main pipe body 22, a branch pipe body group 23 and an aeration ring group 24.

[0043] The air supply member 21 is arranged on the first mounting frame 3 and has an air supply end; the main pipe body 22 is arranged on the first mounting frame 3 in the vertical direction, one end of the main pipe body 22 is connected to the air supply end, and the other end is closed; there are multiple groups of branch pipe body groups 23, and the multiple groups of branch pipe body groups 23 are arranged on the main pipe body 22 in sequence from top to bottom, and each group of branch pipe body groups 23 includes multiple branch pipe bodies 230 arranged circumferentially around the pipe axis of the main pipe body 22, and each branch pipe body 230 is connected to the main pipe body 22; the aeration ring group 24 includes multiple ring pipes 240, and the widths of the multiple ring pipes 240 are consistent, and the inner ring diameter increases uniformly from small to small; each ring pipe 240 is arranged on the branch pipe body group 23 in a one-to-one correspondence, and is connected to the branch pipe body 230 of the branch pipe body group 23, and the inner ring diameter of each ring pipe 240 decreases from top to bottom; an aeration hole 241 is provided on the upper surface of the ring pipe 240. The ring pipes 240 with different inner ring diameters are arranged from bottom to top, and the one with the smallest inner ring diameter is located at the bottom. During the actual aeration process, the disturbance caused by the aeration of the ring pipe 240 at the lower end causes the water to flow upward, thereby causing the water to move to the ring pipe 240 above it, and so on, causing the water to continue to flow in a vertical upward direction, and the odor generated by the oxygenation of the water moves to the hollow area of ​​the inner ring along the direction of the water flow.

[0044] The cover body 4 is installed on the sub-float 10 through the second mounting frame 5. The cover body 4 is located directly above the inner ring hollow area. The cover body 4 can fit together with the surface of the sub-float 10 to form a cover body that seals the inner ring hollow area. The processing component 6 is arranged on the cover body 4 and is used to process the odor in the cover body 4.

[0045] Preferably, the main pipe body 22, multiple groups of branch pipe body groups 23, and aeration ring groups 24 constitute the aeration element 20, and there are multiple groups of aeration elements 20. It should be noted that the aeration elements 20 are evenly arranged below the hollow area of ​​the inner ring, and the air supply element 21 of this embodiment adopts a commercially available air pump, and the main pipe bodies 22 of multiple aeration elements 20 are all connected to the air pump.

[0046] Preferably, the diameter of the branch pipe group 23 decreases from bottom to top. Each branch pipe group 23 connects the main pipe 22 and each annular pipe 240, that is, it is used to introduce the gas in the main pipe 22 into each annular pipe 240. In this embodiment, the size of the gas flow rate introduced into the annular pipe 240 is adjusted from bottom to top based on the diameter of the branch pipe group 23. The bottommost annular pipe 240 is at the deepest part of the water body compared to other annular pipes 240, and the airflow introduced into it is the largest. Since the annular pipe 240 not only oxygenates the surrounding water body, but also disturbs the water flow in the surrounding area and promotes the water flow to flow vertically upward toward the water surface, the deeper the water body position, the greater the airflow of the annular pipe 240, which is more conducive to promoting the deep water body to flow to the water surface faster, so that the odor can be quickly transferred to the inner ring hollow area with the water flow, and then blocked by the cover body 4, and discharged to the outside of the cover body 4 after being processed by the treatment component 6.

[0047] Preferably, Figure 3 As shown, the cross section of the ring tube 240 is a rectangular structure, a V-shaped groove 242 is provided on the upper surface of the ring tube 240, and aeration holes 241 are provided on two inclined surfaces of the V-shaped groove 242. The aeration holes 241 are provided on the inclined surfaces, and when the gas is ejected from the aeration holes 241, it flows in a direction perpendicular to the inclined surfaces, so that the gas can contact the water body more fully, avoiding the problem of insufficient contact caused by a short contact path due to vertical ejection resulting in short contact failure.

[0048] Preferably, the inclination angle of the slope of the V-shaped groove 242 is in the range of 20° to 45°, and in this embodiment is 30°.

[0049] Preferably, Figure 3 As shown, the aeration holes 241 include a first pore group 2411 and a second pore group 2412. The first pore group 2411 is arranged on the inclined surface of the V-shaped groove 242 away from the inner ring side surface of the ring tube 240, and there are two first pore groups 2411. The two groups of first pore groups 2411 are arranged at intervals from top to bottom, and both include first pores arranged along the circumference of the ring center of the ring tube 240; the second pore group 2412 is arranged on the inclined surface of the V-shaped groove 242 close to the inner ring side surface of the ring tube 240, and the second pore group includes second pores arranged along the circumference of the ring center of the ring tube 240, and the second pores are staggered with the first pores.

[0050] The working method of this embodiment is:

[0051] like Figure 1 As shown, the float base 1 is placed in the water area to be treated, and air is supplied to the main pipe 22 through the air supply member 21. The gas sequentially passes through the main pipe 22, the branch pipe group 23, and the aeration ring group 24 to contact the water body, thereby achieving oxygenation of the water body.

[0052] During the aeration process, the disturbance caused by the aeration of the lower ring pipe 240 on the water body causes the water to flow upward, thereby causing the water to move to the ring pipe 240 above it, and so on, causing the water to continue to flow in the vertical upward direction, and the odor generated by the oxygenation of the water body moves to the hollow area of ​​the inner ring along the direction of the water flow, and is then blocked by the cover body 4, and is discharged to the outside of the cover body 4 after being processed by the treatment component 6.

[0053] It should be noted that the processing component 6 of this embodiment includes an exhaust fan, an exhaust duct and activated carbon filler. The exhaust fan is arranged in the cover body 4, one end of the exhaust duct is connected to the exhaust fan, and the other end passes through the cover body 4 and is located outside the cover body 4, and the activated carbon filler is filled in the exhaust duct.

[0054] Example 2

[0055] The difference from Example 1 is that: preferably, Figure 4 As shown, the second mounting frame 5 is a liftable mounting frame. In this embodiment, the second mounting frame 5 adopts a commercially available screw lift, and there are four of them. The four second mounting frames 5 are arranged on the floating body seat 1 and located at the four corners of the inner ring hollow area, and the screws of the screw lift are respectively connected to the lower end of the cover body 4.

[0056] In actual implementation, the lifting structure of the second mounting frame 5 can be lifted and lowered in different time periods to perform oxygenation treatment so as to adapt to the activity time of people in the vicinity of the treated water body.

[0057] Specifically, during the period from 6:00 in the morning to 11:00 in the evening, the cover body 4 is fitted with the surface of the sub-floating body 10 based on the lifting structure of the second mounting frame 5 to form a sealed inner ring hollow area. When oxygenation treatment is performed, the odor is effectively treated to prevent the odor from spreading to the area near the water body and affecting people's activities.

[0058] From 11:00 p.m. to 6:00 a.m. the next day, there are few or even no people active in the area near the treated water body. The hood body 4 is raised based on the lifting structure of the second mounting frame 5. Even if the odor spreads to the area near the water body, it will not have a significant impact on the activities of the people.

[0059] Example 3

[0060] The difference from Example 2 is that: Figure 5 As shown, a blocking assembly 7 is provided at the bottom of the floating body seat 1 , and the blocking assembly 7 includes a counterweight 71 , a rope group 72 and a blocking body 73 .

[0061] There are multiple counterweights 71; the rope group 72 includes multiple rope bodies, one end of each of which is arranged on the sub-floating body 10 around the edge of the inner ring hollow area of ​​the annular structure, and the other end is connected to multiple counterweights 71 in a one-to-one correspondence; the blocking body 73 is a closed-loop structure matching the annular structure, the upper edge of which is arranged at the bottom of the sub-floating body 10 and surrounded by the outer side of the inner ring hollow area, and the lower edge is connected to the counterweight 71. The counterweight 71 is a stainless steel metal ball, and the blocking body 73 is a plastic plate.

[0062] In actual use, it can effectively avoid water disturbance causing large water flow, which then quickly spreads to the surroundings, causing the odor to flow with the water and be discharged from the water surface of the outer area of ​​the floating seat 1.

[0063] Example 4

[0064] The difference from Example 3 is that: preferably, Figure 6 As shown, the baffle body 73 is a flexible structure. The baffle body 73 is made of cloth, specifically a polypropylene filter cloth belt.

[0065] Preferably, a plurality of take-up assemblies 8 are provided on the sub-floating body 10, and each take-up assembly 8 includes a take-up roller 81 and a driving member 82. The take-up roller 81 is rotatably arranged at the bottom of the sub-floating body 10, and a plurality of rope bodies are wound around the take-up roller 81 in a one-to-one correspondence; the driving member 82 is connected to the take-up roller 81 to drive the take-up roller 81 to rotate.

[0066] In actual use, the take-up roller 81 can be used to tighten or loosen the rope to adjust the extended length of the rope, thereby adjusting the effective depth of the blocking body 73 to control the actual blocking depth of the blocking body 73, and adaptively adjusting according to actual conditions.

[0067] The specific models of the above electronic components are not specially specified, and ordinary products available on the market can be selected as long as they can meet the use requirements of the present invention.

[0068] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail.
