Description

Technical Field

[0001] The present 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

[0002] Lack of oxygen in water bodies is the root cause of black and smelly water bodies. Therefore, when treating black and smelly urban 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, thereby increasing the degradation rate of organic pollutants in the water bodies and achieving the purpose of improving water quality. When performing oxygenation treatment on water bodies, the artificial oxygenation equipment of the existing technology is not suitable for areas with relatively dense populations, such as moats, wetland parks and other urban landscape areas. This is mainly because the oxygenation equipment often produces odors when oxygenating water bodies, which then spreads to the air near the water bodies, causing serious discomfort to people nearby.

[0003] For example, Chinese invention patent publication number CN110589974B discloses a system and method for treating black and odorous urban rivers. The system uses an air pump to pump air above the liquid level through an air pipe to the bottom of the river, aerating the water. This aeration disturbs the sediment at the bottom of the river, causing accumulated organic matter and sulfide in the sediment to rise to the surface, emitting a foul odor. Furthermore, since the organic matter in the water is anaerobic before aeration, it is oxidized after aeration, potentially releasing foul-smelling gases such as hydrogen sulfide and ammonia. The odor then spreads into the air near the water, affecting people nearby. For example, Chinese invention patent publication number CN113354089B discloses a device and method for treating black and odorous water bodies in rural areas. The device uses an aeration component to stir the water flow, 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 of organic matter and sulfides accumulated in the bottom mud emitting a foul odor after rising to the water surface, and organic matter in the water releasing foul-smelling gases after oxygenation, which then spreads to the nearby air and affects people. Summary of the Invention

[0038] 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.

[0039] Example 1

[0040] like Figure 1 The sewage ecological purification system for water environment treatment shown includes a float base 1, an aeration assembly 2, a first mounting frame 3, a cover body 4, a second mounting frame 5 and a processing assembly 6.

[0041] The float base 1 is composed of a plurality of sub-floats 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 located in the inner hollow region of the annular structure. The aeration assembly 2 includes an air supply member 21, a main pipe 22, a branch pipe assembly 23, and an aeration ring assembly 24.

[0042] The air supply component 21 is arranged on the first mounting frame 3 and has an air supply end; the main body 22 is arranged on the first mounting frame 3 in the vertical direction, one end of the main 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 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 axis of the main body 22, and each branch pipe body 230 is connected to the main body 22; the aeration ring group 24 includes multiple ring pipes 240, and the widths of the multiple ring pipes 240 are the same, and the inner ring diameter increases uniformly from small to small; each ring pipe 240 is arranged one by one on the branch pipe body group 23, 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 in sequence from bottom to top, and the ring pipe 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, and then causes the water to move to the ring pipe 240 above it. Similarly, the water flow is caused 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.

[0043] 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 provided on the cover body 4 and is used to treat the odor inside the cover body 4.

[0044] Preferably, the main pipe body 22, multiple groups of branch pipe bodies 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 distributed below the hollow area of ​​the inner ring. In this embodiment, the air supply element 21 uses a commercially available air pump, and the main pipe bodies 22 of the multiple aeration elements 20 are all connected to the air pump.

[0045] Preferably, the diameters of the branch pipe groups 23 decrease from bottom to top. Each branch pipe group 23 connects the main body 22 with each annular pipe 240, that is, is used to introduce gas from the main body 22 into each annular pipe 240. In this embodiment, the flow rate of gas entering the annular pipe 240 is adjusted based on the diameter of the branch pipe group 23 from bottom to top. Compared with the other annular pipes 240, the bottommost annular pipe 240 is located at the deepest part of the water body and has the largest airflow. Because the annular pipe 240 not only oxygenates the surrounding water, but also disturbs the water flow in the surrounding area and forces the water flow to flow vertically upward toward the water surface, the deeper the annular pipe 240 is, the greater the airflow is, which is more conducive to promoting a faster flow of deep water to the water surface, thereby allowing the odor to be quickly transferred to the inner ring hollow area with the water flow, and then blocked by the cover body 4. After being treated by the treatment component 6, it is discharged outside the cover body 4.

[0046] Preferably, Figure 3 As shown, the ring tube 240 has a rectangular cross-section and a V-shaped groove 242 on its upper surface. Aeration holes 241 are located on the two inclined surfaces of the V-shaped groove 242. The placement of the aeration holes 241 on the inclined surfaces allows the gas to flow perpendicularly to the inclined surfaces after being ejected from the aeration holes 241, ensuring more complete contact between the gas and the water. This avoids the problem of insufficient contact caused by a shorter contact path due to vertical ejection.

[0047] Preferably, the inclination angle of the V-shaped groove 242 ranges from 20° to 45°, and is 30° in this embodiment.

[0048] 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 provided on the inclined surface of the V-shaped groove 242 away from the inner side surface of the annular tube 240. There are two first pore groups 2411, which are spaced apart from each other from top to bottom and each include first pores arranged along the circumference of the annular tube 240. The second pore group 2412 is provided on the inclined surface of the V-shaped groove 242 close to the inner side surface of the annular tube 240. The second pore group includes second pores arranged along the circumference of the annular tube 240, and the second pores are staggered with the first pores.

[0049] The working method of this embodiment is:

[0050] 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 body 22 through the air supply member 21. The gas passes through the main body 22, the branch pipe group 23, and the aeration ring group 24 in sequence and contacts the water body to achieve oxygenation of the water body.

[0051] 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, and then causes the water to move to the ring pipe 240 above it. Similarly, the water flow is caused 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.

[0052] 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. The activated carbon filler is filled in the exhaust duct.

[0053] Example 2

[0054] 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 float base 1 and located at the four corners of the inner ring hollow area. The screws of the screw lift are respectively connected to the lower end of the cover body 4.

[0055] In actual implementation, the lifting structure of the second mounting frame 5 can be raised and lowered in different time periods to perform oxygenation treatment to adapt to the activity time of people in the area near the treated water body.

[0056] Specifically, from 6:00 a.m. to 11:00 p.m., the lifting structure of the second mounting frame 5 is used to fit the cover body 4 and the surface of the sub-floating body 10 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.

[0057] From 11:00 p.m. to 6:00 a.m. the next day, there are fewer or even no people active in the area near the treated water body. The lifting structure based on the second mounting frame 5 raises the cover body 4. At this time, 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.

[0058] Example 3

[0059] 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 .

[0060] There are multiple counterweights 71; rope assembly 72 includes multiple ropes, one end of which is wrapped around the edge of the inner hollow area of ​​the annular structure and installed on the sub-floating body 10, and the other end is connected to the multiple counterweights 71 in a one-to-one correspondence. Baffle 73 is a closed-loop structure that matches the annular structure. Its upper edge is located at the bottom of the sub-floating body 10 and surrounds the outer side of the inner hollow area, and its lower edge is connected to the counterweights 71. The counterweights 71 are stainless steel metal balls, and the baffles 73 are plastic plates.

[0061] 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 in the outer area of ​​the float seat 1.

[0062] Example 4

[0063] The difference from Example 3 is that: preferably, Figure 6 As shown, the baffle 73 is a flexible structure. The baffle 73 is made of cloth, specifically a polypropylene filter cloth belt.

[0064] Preferably, the sub-float 10 is provided with a plurality of take-up assemblies 8, each of which includes a take-up roller 81 and a drive member 82. The take-up roller 81 is rotatably mounted at the bottom of the sub-float 10, and a plurality of ropes are wound around the take-up roller 81 in a one-to-one correspondence; the drive member 82 is connected to the take-up roller 81 to drive the take-up roller 81 to rotate.

[0065] 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 blocker 73 to control the actual blocking depth of the blocker 73, and adaptively adjusting according to actual conditions.

[0066] The specific models of the above electronic components are not particularly specified, and common products available on the market can be selected as long as they can meet the use requirements of the present invention.

[0067] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
