Description

Technical Field

[0001] The utility model relates to the technical field of ecological environment engineering, and specifically refers to an offshore sewage outlet ecological purification system. Background Art

[0002] There are many sewage outlets in urban lakes that are difficult to intercept. The sewage from these outlets contains a large amount of pollutants such as organic matter, inorganic salts, heavy metals, pathogenic microorganisms, etc., which have a serious impact on the water quality and water ecosystem of the lake.

[0003] For sewage outlets that are difficult to intercept, the commonly used measures are to use ecological ponds, wetlands or water treatment equipment to treat the sewage at the outlet. However, these measures require large engineering construction investments and require sufficient land. However, the land around urban lakes is generally tight, and there are many restrictions on implementation. Therefore, many sewage outlets can only be treated by in-situ purification measures. In-situ purification measures mainly use fences to enclose the water area around the outlet, and then purify the water area through aeration, regular dosing and other measures. This method can reduce the pollution load of the outlet and reduce the impact of the sewage at the outlet on the entire lake. However, because the fence limits the spread of sewage, the water quality of the water area around the outlet will deteriorate or even have odors, and aeration will aggravate the spread of odors, resulting in a worse sensory deterioration in the area around the outlet shoreline. Therefore, this measure cannot be used at sewage outlets in many urban lakes, especially sewage outlets in lakeside parks, squares and other areas. Utility Model Content

[0036] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] The present application relates to an offshore sewage outlet ecological purification system. The ecological purification system of the present application is mainly used for sewage outlets in lakes and rivers for further treatment of sewage at the sewage outlets. The present application constructs an ecological purification system in waters far from the shoreline, does not occupy land, and can treat sewage from multiple outlets at the same time, which not only saves land, but also effectively improves the environment around the sewage outlet shoreline.

[0038] Specifically, Figures 1-2 As shown, the offshore sewage outlet ecological purification system of the present application includes a retaining structure and multiple water treatment units. The retaining structure is a pool structure with an upper opening and a closed bottom and sides. The retaining structure is connected to the sewage outlet through a pipe 8. The retaining structure is a pool structure built in the waters far from the shoreline. The sewage discharged from the sewage outlet enters the retaining structure through the pipe 8, and the sewage discharged from the sewage outlet no longer directly enters the waters; multiple water treatment units are placed inside the retaining structure and on the outlet side to treat the sewage discharged into the retaining structure. The water treatment unit purifies the sewage in the retaining structure, and the treated water is then discharged to the external waters.

[0039] In actual application, the sewage discharged from the sewage outlet enters the enclosure structure through the pipe 8, and the multiple water treatment units in the enclosure structure purify the incoming sewage. The sewage entering the enclosure structure will stay in the enclosure structure for a period of time and will be fully purified by the multiple outlet treatment units until it fully meets the discharge requirements, and finally discharged into the surrounding waters from the upper opening of the enclosure structure.

[0040] In some embodiments of the present application, the present embodiment optimizes the above-mentioned enclosure structure. Specifically, Figure 1 As shown, the enclosure structure of this embodiment includes an enclosure 1 and a steel pipe 2. The enclosure 1 is a waterproof sheet structure with the lower end extending into the water bottom and the upper end extending above the water surface. The enclosure 1 surrounds the pool body structure to form an isolated inside and outside; the steel pipe 2 is vertically inserted into the water bottom and fixedly connected to the enclosure 1.

[0041] The enclosure 1 is a watertight structure used to form a partition wall of the enclosure structure to separate the internal water area from the external water area; the steel pipe 2 is used to fix the enclosure 1 to the water area to form a stable pool structure. In actual use, it is not necessarily limited to the structure of the enclosure 1, and can also be other material structures as long as it meets the requirements of this embodiment. The enclosure structure of this embodiment is simple, and it is extremely convenient to install and disassemble, and is suitable for large-scale promotion and application.

[0042] The enclosure 1 is a watertight enclosure made of PVC soft enclosure, with a height of 10 to 15 cm higher than the surrounding water surface. It is fixed with steel pipes 2 to enclose an independent area in the water. The volume of this area must meet the retention time of discharged sewage for no less than 6 hours. The steel pipes 2 are galvanized steel pipes with a diameter of 50 to 80 mm. The distance between adjacent steel pipes 2 does not exceed 1 m, which serves to fix the enclosure 1.

[0043] In other embodiments of the present application, this embodiment optimizes the above-mentioned water treatment unit, and this embodiment has multiple water treatment units.

[0044] like Figure 2 As shown, the water treatment unit includes artificial water grass 3 at the bottom of the inner side of the enclosure structure. The artificial water grass 3 is made of fiber material and has a density of 9 to 12 clumps / ㎡.

[0045] The water treatment unit also includes fillers 4 filled in the enclosure structure, and the fillers 4 are suspended in the water body in the enclosure structure for adsorption treatment of sewage. A net bag 5 is arranged in the enclosure structure, and the net bag 5 is connected to the inner side of the enclosure structure, and the fillers 4 are evenly fixed on the net bag 5.

[0046] The net bag 5 is a structure for arranging the filler 4. The net bag 5 is made of nylon mesh with a mesh size of 50 to 80 mm. It is a closed net bag installed inside the watertight enclosure 1. The middle and bottom of the net bag are left empty for arranging other structures. The filler 4 is a porous rotating spherical suspended filler with a diameter of 100 to 150 mm. It is arranged inside the net bag 5 with a density of 100 to 200 pieces / m 3 .

[0047] A vertical through hole is provided in the middle of the net bag 5, and a submersible flow aerator 6 is provided in the through hole; a space is left at the bottom of the net bag 5 to facilitate the arrangement of artificial water plants 3, such as Figure 1 and2 The net bag 5 is suspended above the artificial waterweed 3. The submersible aerator 6 pushes the flow in a vertical downward direction, and the oxygenation of the clean water is not less than 6 kg. 2 / h.

[0048] In addition, the water treatment unit of this embodiment also includes an ecological floating bed 7 located outside the upper end of the enclosure structure, and the ecological floating bed 7 is used to treat the overflow from the upper end of the enclosure structure. In actual arrangement, a circle of ecological floating beds 7 is arranged outside the upper end of the enclosure structure.

[0049] That is, the water in the enclosure structure is discharged by overflow, and the overflow water first enters the ecological floating bed 7 and is processed by the ecological floating bed 7; the ecological floating bed 7 adopts a modular finished floating bed, and the layout area width is not less than 2m.

[0050] The interface connecting the pipe 8 of this embodiment and the enclosure structure is located at the bottom of the enclosure structure, that is, the sewage entering the enclosure structure flows from bottom to top, which can make the sewage stay in the enclosure structure longer and make the reaction more complete.

[0051] When the offshore sewage outlet ecological purification system of the present application is actually working: after the sewage is discharged from the sewage outlet, it enters the pipe 8, and the pipe 8 discharges the sewage into the pool structure formed by the enclosure 1. The sewage outlet is located at the bottom of the pool structure formed by the enclosure 1, so the sewage flows from bottom to top. The sewage first contacts the artificial aquatic plants 3 at the bottom, and the sewage is purified by the artificial aquatic plants 3, and then flows upward through the net bag 5 and the filler 4. The filler 4 adsorbs and purifies the sewage, and the submersible flow aerator 6 aerates the pool structure formed by the enclosure 1 to improve the water treatment effect of the entire pool; when the sewage stays in the pool structure formed by the enclosure 1 for a set time, the treated water overflows outward through the upper end of the pool structure formed by the enclosure 1, and the overflowed water enters the ecological floating bed 7, and the ecological floating bed 7 further purifies the water, and finally discharges it into the surrounding waters to complete the sewage treatment process.

[0052] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. The utility model may have various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
