Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to an integrated wastewater purification device. Background Technology

[0002] Due to the continued scarcity of wood fiber raw materials for papermaking in my country for a considerable period, non-wood fiber raw materials will remain crucial. Bamboo fiber, a medium-length fiber with a length between that of softwood and hardwood pulp, possesses excellent pulping properties for papermaking and is considered one of the better non-wood papermaking fiber raw materials. Bamboo pulp can not only produce high-quality household paper, but also, when combined with some commercial wood pulp, can produce high-quality cultural and high-grade newspapers and newsprint. Therefore, using bamboo-based wood pulp for papermaking is an important way to address my country's wood pulp shortage and promote the development of the paper industry.

[0003] Most bamboo pulping enterprises use chemical methods, generating large volumes of high-concentration, high-color wastewater. This wastewater contains abundant sugars, organic acids, amino acids, flavonoids, tannins, and other organic compounds, increasing the difficulty of wastewater treatment. Industrial production typically employs physical, chemical, biochemical, and other combined methods to treat bamboo pulp wastewater, achieving COD removal rates as high as 88-90%. Residual organic pollutants can be removed through coagulation, flocculation, catalytic oxidation, and adsorption, thus meeting national wastewater discharge standards. Since this wastewater generally undergoes conventional pretreatment + biochemical treatment + secondary sedimentation + coagulation + tertiary sedimentation + catalytic oxidation, it can generally meet national discharge standards. However, existing wastewater treatment equipment has high operating costs and significant safety risks. Therefore, optimizing wastewater treatment processes, facilities, and operating methods to improve the production capacity of traditional wastewater treatment processes and ensure safe water supply has become a crucial issue that the water supply and drainage industry needs to address.

[0022] This embodiment discloses an integrated sewage purification device, which is an integrated cylindrical body 43 structure supported by a foundation, such as... Figure 1As shown, the system includes an inlet pipe 1, a sludge pipe 13, a vortex reaction zone, an inclined tube sedimentation zone 6, a sludge sedimentation zone 5, and a filter unit 48 arranged annularly at the bottom of the cylinder 43. The vortex reaction zone includes a straight cylinder 43 vortex reaction chamber 45, an inverted cone vortex reaction chamber 45, and a cylindrical vortex reaction chamber 45. The straight cylinder vortex reaction chamber 45 is located at the center of the bottom of the cylinder 43. The inverted cone vortex reaction chamber 45 is located at the top of the straight cylinder vortex reaction chamber 45. The cylindrical vortex reaction chamber 45 is fitted inside the inverted cone vortex reaction chamber 45, and the open end of the cylindrical vortex reaction chamber 45 faces downward and communicates with the sludge sedimentation zone 5. The top of the cylindrical vortex reaction chamber 45 and the top of the inverted cone vortex reaction chamber 45 are connected. A first gap is formed between the cylinder 43 and the inverted cone swirl reaction chamber 45. The inlet pipe 1 enters the device from the bottom side of the cylinder 43 and is connected to the bottom side of the swirl reaction chamber 45 of the cylinder 43. A first baffle structure is provided inside the inverted cone swirl reaction chamber 45. The inclined tube sedimentation zone 6 is located above the sludge sedimentation zone 5. The inclined tube sedimentation zone 6 includes an inclined tube 25 and a water collection unit 41 above the inclined tube 25. The filtration unit 48 includes a filter tank 8 with filter media 32 and a clear water tank 11 located above the filter tank 8. A backwashing siphon system is provided at the top of the filter tank 8. The sludge sedimentation zone 5 is located above the clear water tank 11. The sludge pipe 13 enters the device from the side of the cylinder 43 and is connected to the bottom side of the sludge sedimentation zone 5.

[0023] Specifically, a pipe mixer is also installed on the water inlet pipe 1, and a dosing pipe is installed on the pipe mixer. The water inlet pipe 1 enters the device from the bottom side of the cylinder 43 and is tangential to the bottom side of the swirl reaction chamber 45 of the straight cylinder 43 that connects to the swirl reaction zone.

[0024] Specifically, the cyclone reaction chamber 45 of the straight cylindrical body 43 is equipped with a cyclone device inlet cylinder 43, which is filled with a number of fillers. The cyclone device inlet cylinder 43 includes a hollow sleeve 18, with a cyclone reaction chamber baffle 17 fixedly connected to the bottom of the sleeve 18. The baffle 17 has multiple evenly distributed small holes, and its diameter matches the inner diameter of the sleeve 18. In this application, a cyclone reaction chamber perforated plate support block 49 is correspondingly provided on the inner wall of the cyclone reaction chamber 45 of the straight cylindrical body 43. The cyclone reaction chamber baffle 17 is supported and fixed by the cyclone reaction chamber perforated plate support block 49. By placing small solid objects such as ceramic balls 19 and steel balls on the cyclone reaction chamber baffle 17 inside the cyclone barrel sleeve 18, the contact reaction time of the wastewater in the cyclone reaction zone is enhanced, thereby improving the purification efficiency.

[0025] Specifically, an inverted cone swirling reaction chamber 45 is provided at the upper straight section of the cylindrical body 43 swirling reaction chamber 45. This inverted cone swirling reaction chamber 45 is specifically a reaction tank with an involute baffle 42. The reaction tank with the involute baffle 42 is closed on all sides, with an open top, and its bottom is connected to the interior of the cylindrical body 43 swirling reaction chamber 45. In this application, a first baffle structure is provided inside the inverted cone swirling reaction chamber 45. This first baffle structure is used to form a swirling channel inside the inverted cone swirling reaction chamber 45 to increase the contact reaction time of wastewater within the inverted cone swirling reaction chamber 45, thereby improving purification efficiency.

[0026] Specifically, the first baffle structure includes four first reaction plates 2. These four first reaction plates 2 are connected to the inner wall of the inverted conical swirling reaction chamber 45 along the radial direction of the cylinder 43, and each of the four first reaction plates 2 has several first through holes formed through it. In this application, the number of first reaction plates 2 can be one, two, or more, and the first reaction plates 2 can also be inclinedly arranged on the inner wall of the inverted conical swirling reaction chamber 45; this application is not limited to these limitations.

[0027] Specifically, the four first reaction plates 2 are spaced apart along the axial direction of the cylinder 43. Between two adjacent first reaction plates 2, the axis of one or more first through holes on one first reaction plate 2 does not overlap with the axis of the first through hole on the other first reaction plate 2. This allows wastewater to flow in a staggered manner between the first and second first reaction plates 2 when passing through the first through hole on the first first reaction plate 2, and then flow through the first through hole of the second first reaction plate 2 to the next first reaction plate 2. This achieves the formation of a swirling channel by the four first reaction plates 2 through multiple first through holes in the axial direction of the inverted cone swirling reaction chamber 45, thereby increasing the contact reaction time of wastewater in the inverted cone swirling reaction chamber 45 and thus improving the purification efficiency.

[0028] Specifically, along the cylinder 43 from bottom to top, between adjacent first reaction plates 2, the inner diameter of the first through hole gradually decreases, and the number of first through holes gradually increases. The first first reaction plate 2 is located below the second first reaction plate 2. The inner diameter of the first through hole on the first first reaction plate 2 is larger than that on the second first reaction plate 2, and the number of first through holes on the first first reaction plate 2 is less than that on the second first reaction plate 2. This structural design increases the flow path of wastewater within the inverted conical vortex reaction chamber 45 and accelerates its flow velocity, thus further improving purification efficiency. In this application, the diameter of the first reaction plate 2 matches the inner diameter of the partitions surrounding the cylinder 43 of the involute baffle 42. A mounting block is correspondingly provided on the inner wall of the involute reaction tank 39, and the first reaction plate 2 is supported and fixed within the inverted conical vortex reaction chamber 45 by the mounting block.

[0029] Specifically, the swirling reaction zone also includes a cylindrical swirling reaction chamber 45, with its open end facing downwards. This cylindrical swirling reaction chamber 45 is fitted over the inverted conical swirling reaction chamber 45, allowing its open end to communicate with the sludge settling zone 5. A first gap is formed between the top of the cylindrical swirling reaction chamber 45 and the top of the inverted conical swirling reaction chamber 45, allowing wastewater flowing through the inverted conical swirling reaction chamber 45 to quickly flow into the cylindrical swirling reaction chamber 45. The resulting sludge settles in the sludge settling zone 5, and the reacted wastewater continues to flow through the inclined tube settling zone 6 located above the sludge settling zone 5. Finally, the wastewater is collected by the water collection unit 41 above the inclined tube 25.

[0030] Specifically, the cylindrical swirling reaction chamber 45 is a cylindrical reaction tank 40 with a sealed top. The cylindrical reaction tank 40 contains a second baffle structure, which forms a swirling channel inside the cylindrical swirling reaction chamber 45 to increase the contact and reaction time of the wastewater within the chamber, thereby improving purification efficiency. In this application, the cylindrical reaction tank 40 is fixedly connected to the support block 23 of the side plate 28 of the cylinder via a reaction tank support 22.

[0031] Specifically, the second baffle structure includes five second reaction plates 31, which are connected along the radial direction of the cylinder 43 between the outer wall of the inverted conical swirling reaction chamber 45 and the inner wall of the cylindrical swirling reaction chamber 45. Each of the five second reaction plates 31 has several second through holes formed through it. In this application, the number of second reaction plates 31 can be one, two, or more, and the second reaction plates 31 can also be inclinedly arranged on the inner wall of the cylindrical swirling reaction chamber 45; this application is not limited to this.

[0032] Specifically, five second reaction plates 31 are spaced apart along the axial direction of the cylinder 43. Between two adjacent second reaction plates 31, the axis of one or more second through holes on one second reaction plate 31 does not overlap with the axis of the second through holes on the other second reaction plate 31. This structural arrangement allows the five second reaction plates 31 to form a swirling channel along the axial direction of the cylindrical swirling reaction chamber 45 through multiple second through holes, thereby increasing the contact reaction time of wastewater within the cylindrical swirling reaction chamber 45 and improving purification efficiency. In this application, the outer diameter of the second reaction plate 31 matches the inner diameter of the partitions surrounding the cylindrical reaction tank 40; corresponding mounting blocks are provided on the inner wall of the cylindrical reaction tank 40 (the second reaction plates 31 are supported and fixed inside the cylindrical swirling reaction chamber 45 by the mounting blocks).

[0033] Specifically, an inclined tube sedimentation zone 6 is located between the cylindrical cyclone reaction chamber 45 and the cylinder 43. An inclined tube bracket 24 of the inclined tube sedimentation zone 6 is connected between the cylinder 43 and the cylindrical cyclone reaction chamber 45. Inclined tubes 25 are placed on the inclined tube bracket 24, and an inclined tube pressure bracket 26 is placed on the inclined tubes 25 and welded together with the cylinder 43 and the cylindrical cyclone reaction chamber 45. In this application, the inclined tube bracket 24 is connected between the cylinder 43 and the cylindrical cyclone reaction chamber 45 via a bracket support block 27, bearing the mud-water pressure generated by the inclined tubes 25 during sedimentation. The inclined tube pressure bracket 26 is connected to the upper part of the inclined tubes 25 and the cylinder 43 and the cylindrical cyclone reaction chamber 45 via a pressure bracket support block 29. The inclined tubes 25, at a 60° inclination angle ф50, are installed on the inclined tube bracket 24.

[0034] Specifically, the inclined tube sedimentation zone 6 also includes a water collection unit 41, which includes an inclined tube clear water collection area 47 located above the inclined tube 25 and a sedimentation water collection tank 30 outside the cylinder 43. The pipes placed outside the main cylinder 43 and the sedimentation water collection tank 30 together constitute the sedimentation water shaft 7.

[0035] Specifically, the filtration unit 48 consists of a filter tank 8 and a clear water tank 11; the filter tank 8 consists of filter media 32, filter plate 33, filter plate support 34, filter head 35, clear water pipe 9 for the filtration zone, siphon backwash riser pipe 10 and siphon backwash downpipe 12. The filter unit 48 is located below the main body of the equipment and is divided into several compartments by filter unit partitions 36. The filter unit partitions 36 are all welded to the bottom plate 20 of the cylinder, the side wall of the cylinder 43, and the cover plate of the filter tank 8. The lower part of the inner tank of the filter tank 8 has filter plates 33, on which filter heads 35 are installed. The filter head 35 is covered with homogeneous filter media 32, which is heavy quartz sand and anthracite. The area where the lower part of the filter head 35 is connected to the cylinder 43 is the filtered water collection area 15. The filter tank 8 and the filter tank cover plate 38 are equipped with a backwashing siphon system. The siphon backwash downcomer 12 passes through the cylinder 43 and enters the water seal trench 46. The water inlet system of the filter unit 48 is a sedimentation water shaft 7 located outside the cylinder 43. The upper part of the sedimentation water shaft 7 is connected to the sedimentation water collection tank 30, and the lower part of the shaft pipe directly enters the interior of the filter tank 8 below the cover plate of the filter tank 8.

[0036] Specifically, the lower end of the siphon riser pipe passes through the filter tank cover plate 38 into the interior of the filter tank 8 and is connected to the filter tank 8 cover plate; the end of the siphon backwash riser pipe 10 is equipped with a filter tank inlet water distribution pipe 14; the lower end of the siphon backwash downpipe 12 is inserted into the water seal trench 46, and the siphon backwash downpipe 12 is equipped with an automatic backwash electric valve and a maintenance valve. The electric valve is equipped with a time relay to control the backwash time; the filtered clean water enters the clean water tank 11 at the top of the filter chamber through the clean water pipe 9 in the filter area. The clean water tank 11 at the top of the filter tank 8 is equipped with a clean water outlet pipe 16, and the bottom drain pipe of the filter tank 8 is at the bottom of the filtered water collection area 15.

[0037] Specifically, the sludge settling zone 5 is a flat-bottomed sludge thickening zone formed by the outer wall of the cyclone reaction chamber 45 of the straight cylinder 43, the lower part of the inclined tube settling zone 6, and the bottom of the entire cylinder bottom plate 20. The sludge pipes 13 are connected to the cylinder 43. In this application, the sludge settling zone 5 is flat-bottomed to increase the volume of the sludge zone; several sludge pipes 13 are provided in the sludge settling zone 5, and automatic sludge discharge angle valves and maintenance valves are installed on the sludge pipes 13.

[0038] In some embodiments, the first baffle structure may further be: one end of the first reaction plate 2 is connected to the inner wall of the inverted cone vortex reaction chamber 45, and the other end of the first reaction plate 2 extends outward; wherein, along the axial direction of the cylinder 43, adjacent first reaction plates 2 are spaced out and staggered, thereby forming a vortex channel inside the inverted cone vortex reaction chamber 45. In this application, the spaced out and staggered arrangement of adjacent first reaction plates 2 increases the flow path of wastewater within the inverted cone vortex reaction chamber 45, further improving the purification efficiency.

[0039] Specifically, a number of first through holes are formed through the first reaction plate 2, which allows a portion of the wastewater to flow quickly through the first through holes to the location of the next first reaction plate 2, thereby accelerating the flow speed of the wastewater in the inverted cone swirling reaction chamber 45 and thus further improving the purification efficiency.

[0040] In summary, by setting up the above structure and utilizing the first baffle structure in the inverted cone swirling reaction chamber of the swirling reaction zone, the contact reaction time of wastewater in the swirling reaction zone is enhanced, thereby improving the purification efficiency.
