Description

Technical Field

[0001] The utility model relates to the technical field of sewage pipe outlet treatment, in particular to a sewage pipe outlet treatment system for rainwater and sewage separation and enhanced treatment. Background Art

[0002] Separate drainage systems separate rainwater and sewage, transporting them through separate pipelines for discharge or subsequent treatment. Rainwater is discharged directly into rivers through a stormwater network, while sewage is collected through a sewage network and sent to a sewage treatment plant for treatment, preventing it from entering rivers and causing pollution. Furthermore, the collection, utilization, and centralized management of rainwater discharge reduce the impact of water volume on sewage treatment plants, ensuring their efficiency.

[0003] However, complete rainwater and sewage separation remains difficult in many areas, particularly in older urban areas, leading to the continued discharge of sewage into rivers on sunny days. Furthermore, pollution from rainwater runoff entering rivers through stormwater pipes is a significant factor affecting river water quality. Limited available land in central urban areas limits the applicability of measures such as rainwater storage ponds. Therefore, effective river pollution control requires in-situ treatment of uninterrupted sewage outlets to reduce or eliminate their impact on the waterway.

[0004] The existing utility model patent document with the announcement number CN220550061U discloses a biological purification system for in-situ treatment of an outlet. The system is arranged at the outlet into the river and mainly includes a closed-loop frame formed by connecting pipes. The closed-loop frame is connected to a plug pipe, which is inserted into the riverbed to fix the closed-loop frame. A knotless mesh is arranged in the closed-loop frame, and aquatic plants are planted on the knotless mesh. The knotless mesh is also connected to a microbial attachment base, which is suspended in the water. The synergistic effect of the upper plants and the lower microbial attachment base is utilized to improve the decomposition efficiency of pollutants. The plug pipe is inserted into the riverbed so that the closed-loop frame is not easily washed away by water, thereby improving the impact load resistance of the river and providing a good foundation for stabilizing the water quality of the river. One or more aquatic plants can be flexibly selected according to the current status of the water body. At the same time, the arrangement of aquatic plants can not only effectively decompose pollutants but also improve the surrounding landscape environment.

[0005] Although the above-mentioned biological purification system for in-situ treatment of the outlet can solve the corresponding technical stability problem, its closed-loop frame is inserted into the riverbed through a cannula to achieve a fixing function. However, when the water flow rate is large, the cannula cannot be well fixed on the riverbed and is easily washed away by the water flow, thereby reducing the fixing effect of the closed-loop frame and affecting the normal use of the biological purification system for in-situ treatment of the outlet.

[0006] Therefore, a sewage pipe outlet treatment system with enhanced rainwater and sewage separation is proposed. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 5 The present embodiment provides a sewage pipe outlet treatment system for enhanced treatment of rainwater and sewage separation, comprising: a supporting mechanism 100, a microbial attachment base 200, a supporting mechanism 300 that can be connected to a river dam, and an assembly mechanism 400 for realizing a detachable connection between the supporting mechanism 100 and the supporting mechanism 300. The microbial attachment base 200 is arranged below the supporting mechanism 100, the supporting mechanism 100 is arranged in the inner cavity of the supporting mechanism 300, and the assembly mechanism 400 is arranged between the supporting mechanism 100 and the supporting mechanism 300; the supporting mechanism 300 includes an outer frame 310 with a U-shaped structure and located at the sewage pipe outlet, the supporting mechanism 100 is located in the inner cavity of the outer frame 310, both ends of the outer frame 310 are fixedly connected to a mounting plate 320, the mounting plate 320 and the river dam are fixedly connected by expansion bolts, and at least four assembly mechanisms 400 are regularly distributed between the outer frame 310 and the supporting mechanism 100.

[0029] Among them, the supporting mechanism 100 includes an inner frame 110 located in the inner cavity of the outer frame 310, the inner cavity of the inner frame 110 is fixedly connected to a knotless mesh 120, and multiple microbial attachment bases 200 are fixedly connected to the knotless mesh 120 and are regularly distributed. The assembly mechanism 400 is located in the grid between the inner frame 110 and the knotless mesh 120.

[0030] It should be noted that the working principles of the knotless mesh 120 and the microbial attachment base 200 are respectively consistent with the knotless mesh and microbial attachment base in a biological purification system for in-situ treatment of an outlet disclosed in the utility model patent document with the existing publication number CN220550061U. Aquatic plants are planted on the knotless mesh, and the microbial attachment base is connected under the knotless mesh. The microbial attachment base is suspended in the water. The synergistic effect of the upper plants and the lower microbial attachment base is utilized to improve the efficiency of pollutant decomposition. The microbial attachment base is mainly composed of a central rope and a three-dimensional elastic filler. The three-dimensional elastic filler is selected from corrosion-resistant, high-temperature-resistant, and aging-resistant varieties. A special wire drawing and wool making process is used to interweave and fix the silk strips on the central rope to form a suspended three-dimensional elastic filler. In the effective area, air, water, and biofilm can be fully contacted and exchanged in all directions. Not only can the biofilm be implanted on each silk strip and maintain good activity, but also an increasingly larger specific surface area is obtained during operation, which can carry out good metabolism. It is a major component for pollutant degradation. It is an existing technology and will not be described in detail in this technical solution.

[0031] Among them, the lower part of one side of the mounting plate 320 is fixedly connected with a reinforcement rod 330 at an angle, and the other end of the reinforcement rod 330 is fixedly connected to the bottom of the outer frame 310. The reinforcement rod 330 can provide auxiliary support for the outer frame 310, so that a stable triangular structure can be formed between the outer frame 310, the mounting plate 320 and the reinforcement rod 330, which helps to improve the stability of the outer frame 310 when supported.

[0032] Among them, the assembly mechanism 400 includes a fixed clamp 410 fixedly connected to the upper surface of the inner frame 110, and a movable clamp 420 adapted to the fixed clamp 410 is movably connected to the lower surface of the inner frame 110. The fixed clamp 410 is overlapped on the outer frame 310, and the fixed clamp 410 and the movable clamp 420 are interlocked to form a limiting cavity. A connecting part 430 is provided between the fixed clamp 410 and the movable clamp 420, and a sliding part 440 is provided between the movable clamp 420 and the inner frame 110. By rotating the movable clamp 420, the engagement or opening operation with the fixed clamp 410 can be achieved, which facilitates the assembly operation of the supporting mechanism 100 and the supporting mechanism 300.

[0033] Among them, the connecting member 430 includes a first protrusion 431 integrally formed on the side of the fixed clamp 410 away from the knotless mesh 120, and a second protrusion 432 integrally formed on the side of the movable clamp 420 away from the knotless mesh 120. A through hole 433 for the binding rope to pass through is provided on the first protrusion 431 and the second protrusion 432. By passing the binding rope through the through holes 433 on the first protrusion 431 and the second protrusion 432 in turn and tying them to fix, the fixed clamp 410 and the movable clamp 420 can be fixed, so that the fixed clamp 410 and the movable clamp 420 are stably maintained in a buckled state, thereby achieving the effect of stable connection.

[0034] Among them, the sliding part 440 includes an annular groove 441 opened on the surface of the inner frame 110, and the inner cavity of the annular groove 441 is slidably connected with an arc strip 442, and the arc strip 442 is fixedly connected to the inner wall surface of the movable clamp 420. The sliding part 440 can realize a rotatable connection between the movable clamp 420 and the inner frame 110, which facilitates the flipping and opening operation of the movable clamp 420.

[0035] The cross-sectional diameter of the arc strip 442 is larger than the cross-sectional opening size of the annular groove 441 , which effectively prevents the arc strip 442 from slipping out of the inner cavity of the annular groove 441 , further improving the stability of the movable clamp 420 during rotation.

[0036] Among them, the inner wall surface of the fixing clamp 410 is fixedly connected with an insertion rod 450, and the top of the surface of the outer frame 310 is provided with a socket 460 adapted to the insertion rod 450, and the bottom end of the insertion rod 450 is inserted into the inner cavity of the corresponding socket 460. When the supporting mechanism 100 is assembled to the supporting mechanism 300, the insertion rod 450 is first aligned with the socket 460 and inserted, which can play a preliminary limiting role on the supporting mechanism 100, and can limit the horizontal position of the supporting mechanism 100 in the supporting mechanism 300, further improve the connection firmness of the supporting mechanism 100 and the supporting mechanism 300, and facilitate the subsequent connection operation of the first protrusion 431 and the second protrusion 432.

[0037] The working principle of the present invention is as follows: the mounting plate 320 is fixed to the sewage outlet of the dam by expansion bolts, and a plurality of regularly distributed microbial attachment bases 200 are tied under the knotless mesh 120 according to actual use requirements, and then the supporting mechanism 100 is placed in the inner cavity of the outer frame 310 so that the microbial attachment base 200 is suspended in the water, and the insertion rod 450 is aligned with the corresponding insertion hole 460 and inserted so that the fixed clamp 410 is overlapped on the outer frame 310, and the initial limiting operation of the inner frame 110 is completed, and then the movable clamp 420 is rotated, and the movable clamp 420 drives the arc strip 460 to rotate. 442 slides in the inner cavity of the annular groove 441, and the movable clamp 420 drives the second protrusion 432 to rotate synchronously until the movable clamp 420 rotates to the maximum. At this time, the fixed clamp 410 is engaged with the movable clamp 420, and the first protrusion 431 is in contact and aligned with the second protrusion 432. Finally, the binding rope is used to pass through the through holes 433 on the first protrusion 431 and the second protrusion 432 in turn and tied and fixed, thereby completing the secondary positioning operation of the inner frame 110, and then completing the assembly operation of the supporting mechanism 100 and the supporting mechanism 300. Subsequently, aquatic plants can be planted above the knotless mesh 120.

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
