Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, in particular to an integrated sewage treatment system. Background Art

[0002] The integrated sewage treatment system is a sewage treatment system that integrates multiple treatment units and technologies. It is designed to efficiently treat various types of sewage and convert them into water resources that can be safely discharged or recycled. It realizes multi-stage, efficient and comprehensive utilization of sewage treatment and is suitable for various scenarios such as urban sewage treatment plants, industrial wastewater treatment, rural sewage treatment, and aquaculture tailwater treatment. The design of these systems should not only consider treatment efficiency and effluent quality, but also focus on the comprehensive optimization of energy consumption, operating costs and environmental impact.

[0003] A Chinese patent application CN116395911B discloses an integrated aquaculture wastewater treatment system, the technical scheme of which is as follows: it includes a bottom plate and an inner tank body, an intermediate tank body and an outer tank body, the bottom plate, the inner tank body, the intermediate tank body and the outer tank body are all circular; a central sedimentation chamber is arranged in the inner tank body, the top of the central sedimentation chamber is connected to a water inlet pipe, and a mud discharge mechanism is arranged at the bottom; a clean water chamber is arranged between the inner tank body and the intermediate tank body, and the top of the central sedimentation chamber is connected to the clean water chamber; a biological treatment area, an aeration area, an ecological purification area and a water outlet area are arranged between the intermediate tank body and the outer tank body, and a partition wall with a filtering function is arranged between the biological treatment area and the aeration area, and between the aeration area and the ecological purification area, the top of the clean water chamber is connected to the biological treatment area, an aeration mechanism is arranged in the aeration area, plants are planted in the ecological purification area, and the ecological purification area is connected to the water outlet area. This technology can effectively treat tail water, can be flexibly installed, has high integration, and occupies a small area.

[0004] However, the above technology often has the following defects: although it can save space, the process design is not sophisticated enough, and the treatment effect is not ideal when facing some sewage with high pollutant content. In addition, the overflow position and overflow area between the various areas are not reasonably designed, resulting in the sewage staying time in each area being too short, affecting the sewage treatment efficiency of each area. For example, after the sewage enters the central sedimentation chamber, it can flow from various positions on the top of the central sedimentation chamber to the clean water chamber, and then flow to the biological treatment area through a larger overflow surface. This causes part of the sewage to flow directly from the central sedimentation chamber to the biological treatment area without staying in the clean water chamber for enough time, making it difficult to achieve the effect of secondary sedimentation.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 7 As shown, the integrated sewage treatment system of the present invention comprises:

[0035] A tank body 1, wherein the tank body 1 is circular and is provided with a group of tank bodies 1, and a group of tank bodies 1 is concentrically distributed; the chamber between the tank bodies 1 is divided into a primary sedimentation area 2, a biological treatment area 3, a secondary sedimentation area 4, an ecological purification area 5 and a disinfection area 6 from the inside to the outside; a mud discharge mechanism is provided at the bottom of the primary sedimentation area 2 and the secondary sedimentation area 4, and the mud discharge mechanism can be a centrifugal pump, a plunger pump or a screw pump, etc., and the sludge inside the primary sedimentation area 2 and the secondary sedimentation area 4 is discharged through the mud discharge mechanism; the biological treatment area 3 is used to place biological fillers, such as annular fillers, spherical fillers, tubular fillers, spiral fillers, etc., for the growth and reproduction of microorganisms to treat sewage; the ecological purification area 5 is used to plant aquatic plants to further treat sewage;

[0036] A partition plate 7, wherein a group of the partition plates 7 are provided and respectively located between adjacent tank bodies 1; adjacent partition plates 7 are mutually staggered in the radial direction of the tank body 1;

[0037] Overflow grooves 8 are provided at the top of each of the pool bodies 1 at positions corresponding to the partitions 7, and a group of overflow grooves 8 have increasing depths from the inside to the outside; the overflow grooves 8 and the partitions 7 are close to each other and staggered from the inside to the outside.

[0038] Although the integrated sewage treatment system in the prior art can save floor space, it is not sophisticated enough in process design. The treatment effect is not ideal when facing sewage with a high pollutant content. In addition, the overflow position and overflow area between the various areas are not reasonably designed, resulting in the sewage staying in each area for too short a time, affecting the sewage treatment efficiency of each area. For example, after the sewage enters the central sedimentation chamber, it can flow from various positions on the top of the central sedimentation chamber to the clean water chamber, and then flow to the biological treatment area 3 through a larger overflow surface. This causes part of the sewage to flow directly from the central sedimentation chamber to the biological treatment area 3 without staying in the clean water chamber for enough time, making it difficult to achieve the effect of secondary sedimentation.

[0039] When treating sewage, the present invention first pre-treats the sewage, uses a screen or a grille to remove large particles of impurities and solid waste in the sewage, and then passes the sewage into the primary sedimentation area 2. After preliminary sedimentation in the primary sedimentation area 2, the clean water on the top flows through the overflow trough 8 to the biological treatment area 3, and the aerobic organisms in the biological treatment area 3 are used to degrade and treat the organic matter in the sewage. Then, it flows through the overflow trough 8 to the secondary sedimentation area 4, and the microorganisms and residual suspended matter in the sewage are secondary precipitated. Then, it flows through the overflow trough 8 to the ecological purification area 5, and through the growth and metabolism of aquatic plants, the nutrients and organic matter such as nitrogen and phosphorus remaining in the sewage are further absorbed, adsorbed and degraded, thereby reducing the eutrophication of the water body. Then, it flows through the overflow trough 8 to the disinfection area 6 for disinfection, and then the sewage is discharged outward through the overflow trough 8.

[0040] The present invention forms a primary sedimentation area 2, a biological treatment area 3, a secondary sedimentation area 4, an ecological purification area 5 and a disinfection area 6 by arranging a plurality of concentrically distributed pool bodies 1. The process design is more reasonable and efficient, and a truly integrated treatment process is realized. The degree of purification of sewage is improved, and the area occupied by facilities is reduced. The present invention can be applied to most types of sewage. By reasonably designing the positions of the partitions 7 and the overflow troughs 8, the sewage can flow in a whole ring in each area when passing through the area, so that each position in each area is fully utilized, prolonging the residence time of the sewage in each area, ensuring that the sewage is purified to a sufficient degree, and improving the treatment effect of the sewage.

[0041] The biological treatment area 3 and the ecological purification area 5 are both provided with an annular aeration pipe 9 at the bottom; the aeration pipe 9 is connected to an external air source through an air supply pipe 10; a group of air nozzles 11 are evenly distributed on the surface of the aeration pipe 9; by connecting the air supply pipe 10 to an external air source, the aeration pipe 9 is used to supply air to the biological treatment area 3 and the ecological purification area 5 respectively, so as to provide air for the growth of aerobic microorganisms and aquatic plants, thereby improving the degradation efficiency of organic matter, and the bubbles generated by aeration can disturb the water body during the upward movement, promote the tumbling and exchange of the water body in the vertical direction, and make the dispersion of microorganisms and impurities more uniform.

[0042] As a preferred embodiment of the present invention, a mounting column 12 is provided inside the primary sedimentation zone 2; a rotating column 13 is rotatably connected to the top of the mounting column 12; a driving mechanism for controlling the rotation of the rotating column 13 is provided inside the mounting column 12; a swing arm 14 is fixedly connected to the surface of the rotating column 13, and the swing arm 14 extends to the top of a group of tank bodies 1; the swing arm 14 is provided with a dosing mechanism 15 at the corresponding positions of the primary sedimentation zone 2, the secondary sedimentation zone 4 and the disinfection zone 6; the dosing mechanism 15 corresponding to the primary sedimentation zone 2 and the secondary sedimentation zone 4 is used to add flocculants, and the dosing mechanism 15 corresponding to the disinfection zone 6 is used to add disinfectants;

[0043] The specific structure of the medicine adding mechanism 15 may include: a medicine box 38 ; a medicine adding pipe 39 is connected to the bottom of the medicine box 38 ; and the medicine adding pipe 39 is controlled by an electric control valve 40 .

[0044] During the treatment process, flocculants and disinfectants are respectively added into the primary sedimentation area 2, the secondary sedimentation area 4 and the disinfection area 6 through the dosing mechanism 15, so that the suspended matter in the sewage in the primary sedimentation area 2 and the secondary sedimentation area 4 can be quickly flocculated and settled, and the sewage in the disinfection area 6 can be quickly disinfected. The driving mechanism controls the rotation of the rotating column 13 and the swing arm 14 to drive the dosing mechanism 15 on the surface thereof to continuously move above their respective areas, thereby improving the uniformity of the dosage of the agents and further improving the treatment efficiency of the water body.

[0045] A group of support wheels 16 are evenly distributed on the lower side of the swing arm 14, and the support wheels 16 are respectively in contact with the top of each pool body 1; by providing the support wheels 16, during the rotation of the swing arm 14, multiple support wheels 16 can roll on the top of each pool body 1 to support and balance the swing arm 14 and improve its movement stability.

[0046] As a preferred embodiment of the present invention, the swing arm 14 is provided with a fishing mechanism 17 at corresponding positions of the biological treatment area 3 and the ecological purification area 5;

[0047] The fishing mechanism 17 includes a mounting block 18; a paddle 19 is disposed on the surface of the mounting block 18; curling portions 20 are disposed on both sides of the paddle 19; a notch 21 is disposed on the top of the curling portion 20, and a storage cavity 22 is disposed at the bottom of the curling portion 20.

[0048] In actual treatment, there is often scum on the surface of the water in the biological treatment area 3 and the ecological purification area 5. The reason is that during the biological treatment process, microorganisms will grow and reproduce by degrading organic matter. When their biological volume or aggregation reaches a certain level, some scum may be formed, or the organic or inorganic colloid substances in the sewage may sometimes aggregate to form scum during the biological treatment process, or some chemical substances or solid particles may form scum due to sedimentation. These scums are usually normal products of the sewage treatment process.

[0049] During the process of the swing arm 14 driving the fishing component to rotate, the paddle 19 moves on the top of the water body, thereby pushing the scum on the surface of the water body, and then the scum moves to both sides along the surface of the paddle 19 and enters the curled part 20 through the notch 21 for storage, thereby achieving the scum fishing and enhancing the sewage removal effect of the system. By controlling the rotation direction of the swing arm 14 to always be opposite to the water flow direction, the paddle 19 pushes the water body in the opposite direction inside the biological treatment area 3 and the ecological purification area 5, respectively, giving the sewage a tendency to flow back, increasing the flow resistance of the sewage, thereby further extending its residence time in the area, and enhancing the sewage purification effect of the system as much as possible.

[0050] Since the paddle 19 needs to move on the top of the water body, the aquatic plants in the ecological purification area 5 are preferably submerged plants, such as arrow grass, cattail, calamus, iris, water plantain, etc.

[0051] A slide groove is provided on the surface of the mounting block 18; a slide bar 23 is fixedly connected to the surface of the paddle plate 19, and the slide bar 23 is slidably connected to the inside of the slide groove; a guide plate 24 is fixedly connected to the bottom of the slide bar 23; a spring 25 is fixedly connected between the guide plate 24 and the mounting block 18; a roller 26 is arranged at the bottom of the paddle plate 19; both sides of the partition 7 inside the biological treatment area 3 and the ecological purification area 5 are fixedly connected with an inclined plate 27; when the fishing component moves to the partition 7, the roller 26 at the bottom of the paddle plate 19 can roll on the surface of the inclined plate 27, causing the paddle plate 19 to move upward and compress the spring 25, so that the paddle plate 19 can smoothly cross the partition 7, and then the spring 25 drives the paddle plate 19 to reset downward and re-extend into the water body. This structure ensures that the movement of the paddle plate 19 will not interfere with the partition 7, and the swing arm 14 always keeps moving in the opposite direction of the water flow.

[0052] As a preferred embodiment of the present invention, a slag outlet 28 is provided at the bottom of the storage chamber 22; a fixing ring 29 is fixedly connected inside the storage chamber 22; a guide rod 30 is slidably connected inside the fixing ring 29; a spring 31 is fixedly connected between the upper end of the guide rod 30 and the fixing ring 29, and the lower end of the guide rod 30 extends to the inside of the slag outlet 28 and is fixedly connected to a blocking block 32; a collection box 33 is slidably connected inside the partition 7 inside the biological treatment area 3 and the ecological purification area 5, and the top of the collection box 33 is open; magnetic blocks 34 are fixedly connected at both sides of the collection box 33, and the magnetic blocks 34 are connected to the sealing block 32. The blocking blocks 32 attract each other when they are close to each other; under normal circumstances, the blocking block 32 is located inside the slag outlet 28 and blocks it. Whenever the paddle 19 moves above the partition 7, the magnetic block 34 attracts the blocking block 32 to move downward and separate from the slag outlet 28, so that the slag inside the curled portion 20 and the storage cavity 22 can fall into the collection box 33 below through the slag outlet 28, thereby collecting the slag. After the paddle 19 passes over the partition 7, the spring 2 31 drives the blocking block 32 to reset upward through the guide rod 30 and re-block the slag outlet 28. When the collection box 33 is full, the collection box 33 is pulled upward and the slag inside it is poured out.

[0053] A group of water holes 35 are evenly distributed on the surface of the curled portion 20; by providing multiple water holes 35, after sewage carrying scum enters the curled portion 20, water can be discharged outward through the multiple water holes 35, while the scum remains in the curled portion 20, thereby improving the efficiency of catching the scum, and in the process of the paddle 19 gradually rising along the inclined surface, the water in the storage chamber 22 can be discharged through the water holes 35, preventing a large amount of water from entering the collection box 33 after the scum outlet 28 is opened.

[0054] A group of protrusions 36 are evenly distributed on the upper side of the inclined plate 27; the roller 26 can intermittently contact the protrusions 36 during the movement of the surface of the inclined plate 27, prompting the paddle 19 to continuously shake up and down, thereby shaking the scum in the curled portion 20 into the storage chamber 22, reducing the adhesion residue between the scum and the inner wall of the curled portion 20, and then the scum can quickly fall into the collection box 33 after the subsequent slag outlet 28 is opened, and the shaking process will accelerate the water in the storage chamber 22 to be discharged outward through the water hole 35, further reducing the water entering the collection box 33.

[0055] The top of the collecting box 33 is fixedly connected with a support plate 37 at a position corresponding to the inclined plate 27; by providing the support plate 37, the roller 26 can roll on the surface of the support plate 37 when it moves to the top of the partition 7, thereby supporting the roller 26 to prevent jamming.

Figure 1As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
