Description
The present application is a division according to the Chinese invention application with the application number of 202111037853.9 and the application date of 2021, 09 and 06.
Technical Field
The invention relates to the technical field of sewage treatment, in particular to a high-density sedimentation tank.
Background
In recent years, due to the large discharge of domestic sewage, garbage and industrial wastewater, the treatment work of water pollution is deeper. People pay more attention to the quality of water in the process of using water resources. Therefore, a high-density sedimentation tank is often used in water treatment. The high-density sedimentation tank has the advantages of sedimentation and coagulation, small occupied area and high utilization value, so that the high-density sedimentation tank has the characteristics of high integration level, high automation and high water yield. The high-density sedimentation tank is a modern sewage treatment technology integrating flocculation, reaction, sedimentation, clarification and sludge concentration technologies.
The high-efficiency sedimentation tank applied at present in China has larger difference in the aspects of tank arrangement, operation parameters and the like, and has higher requirement on operation management. And due to the lack of design standards, the practical use is often difficult to exert due effects.
Disclosure of Invention
The application provides a high density sedimentation tank, comprising a reaction zone and a clarification zone. Wherein the reaction zone is divided into a mixing zone and a plug flow zone by a guide wall; the flow pushing area is defined by a flow guide wall and a plurality of baffle plates; the baffle plate extends upwards from the bottom of the high-density sedimentation tank and faces different directions, so that water flow can be split into at least three flow directions; and the height of the baffle plate gradually decreases as the baffle plate approaches the guide wall. The sewage treated by the reaction zone flows into the clarification zone from the top of the plug flow zone.
In the prior art, the liquid in the plug flow area can only fall along one wall body to flow into the clarification area, so that the liquid in the middle area of the wall is concentrated to pour out, the flow speed is high, and turbulence is caused; and the area close to the edge of the wall body has less liquid distribution and relatively low flow velocity. And too large flow speed and uneven water flow distribution can lead to incapability of completely settling sewage and influence the quality of sewage treatment. Compared with the prior art, in the technical scheme provided by the application, the flow pushing area is formed by the flow guide wall and a plurality of baffle plates facing different directions, liquid can fall along the surface where each baffle plate is positioned, the flow path of the liquid is increased under the condition of equal flow, and the flow velocity of the liquid is reduced; on the other hand, the inventors found that setting the height of the baffle plates to gradually decrease as approaching the guide wall can make the water distribution in the plug flow area more uniform, i.e., can make the flow velocity of sewage falling along each baffle plate more even. The term "gradually decreasing height" as used herein may refer to a gradient decrease, a gradual, ramp-like decrease, or a combination thereof. These improvements all promote more complete sedimentation of the liquid to improve the quality of the wastewater treatment. In addition, the baffle plate is smaller than the occupied space of the wall body, is flexible to install, can be adjusted according to production requirements, and can integrally improve the occupied utilization rate of the high-density sedimentation tank and reduce the construction cost.
Specifically, in one embodiment, the flow pushing area includes a first baffle plate, a second baffle plate, and a third baffle plate that are sequentially connected; the second baffle plate is parallel to the guide wall, the first baffle plate and the third baffle plate are equal in height, and the heights of the first baffle plate and the third baffle plate are 8-15 millimeters (mm) lower than the height of the second baffle plate. In other words, in the technical scheme, the second deflector which is farthest from the guide wall is highest in height, the first deflector and the third deflector which are connected with the guide wall are slightly lower than the second deflector in height, water flow which is flushed from the middle area can be effectively split and concentrated through the structure, and water distribution in the guide flow pushing area is more uniform.
In another embodiment, the plug flow zone comprises a first baffle, a second baffle, and a third baffle connected in sequence. Wherein the second baffle plate is parallel to the guide wall, and the width of the second baffle plate is L 2 The second baffle is configured to: at the top of the second baffle 0.2L from the edge 2 ～0.4L 2 Is beveled downwardly 15-25 mm toward the edge of the second baffle. That is, if the two lowest points of the second baffle plate after the beveling are connected, the top of the second baffle plate is isosceles trapezoid, and the height of the isosceles trapezoid is 15-25 mm; if the height from the bottom of the high-density sedimentation tank to the top edge of the second baffle is defined as the maximum height of the second baffle, the bottom of the high-density sedimentation tank is moved to the second baffleThe height of the lowest point of the plate after beveling is defined as the minimum height of the second deflector, and the heights of the first deflector and the third deflector do not exceed the minimum height of the second deflector.
Further, the inventors found that if the heights of the first baffle and the third baffle are reduced by 8 to 15mm relative to the minimum height of the second baffle on the basis of the above embodiments, the liquid flow rate can be reduced by 2 to 4 times relative to the highest flow rate of the concentrated falling liquid in the middle area in the prior art, and the water distribution in the plug-flow area is more uniform. That is, the small change of the height of the baffle plate improves the turbulence phenomenon of the high-density sedimentation tank greatly, and the technical scheme has the advantages of simple structure, convenient industrial production, construction and improvement.
In the above embodiment, the widths of the first baffle, the second baffle, and the third baffle are respectively L 1 、L 2 、L 3 Wherein L is 1 ＝L 3 ，L 2 ＝5L 1 ～15L 1 . Because the wall body with two ends plugged in the prior art is not adopted in the technical scheme, the area of the clarification area, the effect of reducing the liquid flow rate and enabling the liquid flow rate to be more uniform and the sedimentation capacity are required to be comprehensively considered, and therefore the plug flow area of the structure is designed.
In the above embodiment, the height of the second baffle is 2.7 to 3.8 meters (m).
Further, the mixing zone comprises a reaction tank, sewage can enter the mixing zone from the bottom of the reaction tank after entering the high-density sedimentation tank, and sewage treated by the reaction tank flows out from the top of the reaction tank and downwards along the guide wall, and then can flow from below the guide wall to the plug flow zone.
Further, the clarification area comprises a concentration area, a water distribution area and an inclined tube area; wherein, the sewage which enters the clarification zone through the plug flow zone is accumulated in the water distribution zone; sludge in the sewage in the water distribution area is deposited downwards to the concentration area and can be discharged from the bottom of the concentration area to a high-density sedimentation tank; the liquid in the water distribution area is accumulated upwards to the inclined tube area, and the water is filtered by the inclined tube area to obtain the water.

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below.
As shown in fig. 1, the high-density sedimentation tank provided by the application comprises a reaction zone 20 and a clarification zone 30, wherein the reaction zone 20 is divided into a mixing zone 21 and a plug flow zone 23 by a guide wall 22.
In one embodiment of the present application, the mixing zone 21 includes a reaction tank 211, after sewage enters the high-density sedimentation tank, the sewage can enter the mixing zone 21 from the bottom of the reaction tank 211, and the sewage treated by the reaction tank 211 flows out from the top of the reaction tank 211 and flows downwards along a guide wall 22, and the guide wall 22 has a distance from the bottom of the high-density sedimentation tank, so that the liquid can flow into the plug flow zone 23.
In one embodiment of the present application, clarification zone 30 includes a water distribution zone 32, a concentration zone 31, and a chute zone 33. The sewage which enters the clarification zone 30 through the plug flow zone 23 is accumulated in the water distribution zone 32, and then the sludge in the sewage is deposited downwards to the concentration zone 31 and can be discharged from the bottom of the concentration zone 31 to a high-density sedimentation tank; as shown in fig. 1, the concentration zone 31 is provided with a mud scraper 311. Along with the continuous rise of the liquid level of the water distribution area 32, the liquid is accumulated in the inclined tube area 33, and the liquid is filtered through the inclined tube 331 of the inclined tube area 33 to obtain clear water.
In particular, the present application modifies the plug flow zone. In any embodiment of the present application, the flow-pushing area 23 is defined by the flow-guiding wall 22 and the plurality of baffles 10; the baffle plate 10 extends upwards from the bottom of the high-density sedimentation tank, has the height of 2.7-3.8 m and faces different directions, and can split water flow into at least three flow directions; and the height of the baffle 10 gradually decreases as it approaches the guide wall 22. The sewage treated in the reaction zone 20 flows into the clarification zone 30 from the top of the plug flow zone 23.
This configuration increases the path of the liquid flow at equal flow rates, reducing the flow rate of the liquid; the height of the baffle plate 10 is gradually reduced along with the approach of the guide wall 22, so that the water distribution in the plug flow area 23 can be more uniform. These improvements all promote more complete sedimentation of the liquid to improve the quality of the wastewater treatment. In addition, the baffle plate 10 has smaller occupied space than the wall body, is flexible to install, can be adjusted according to production requirements, and can integrally improve the occupied space utilization rate of the high-density sedimentation tank and reduce the construction cost.
Specifically, in the embodiment shown in fig. 2, the plug flow region 23 includes a first baffle plate 11, a second baffle plate 12, and a third baffle plate 13, which are sequentially connected; the second baffle plate 12 is parallel to the guide wall 22, the first baffle plate 11 and the third baffle plate 13 are equal in height, and the heights of the first baffle plate 11 and the third baffle plate 13 are 8-15 mm lower than the height of the second baffle plate 12. As can be seen from fig. 2, the second baffle plate 12 furthest from the guide wall has the highest height, the first baffle plate 11 and the third baffle plate 13 connected with the guide wall 22 have a slightly lower height than the second baffle plate 12, and the structure can effectively split and concentrate the water flow rushing from the middle area, and the water distribution of the guiding plug flow area 23 is more uniform.
Fig. 3 shows another embodiment of the present application, and likewise, the flow pushing zone 23 includes a first baffle 11, a second baffle 12 and a third baffle 13 connected in sequence, wherein the second baffle 12 is parallel to the flow guiding wall 22, and the width of the second baffle is L 2 . The second baffle 12 is, in contrast, configured to: 0.2L from the left and right edges at the top of the second baffle 12 2 ～0.4L 2 Is beveled downward 15-25 mm toward the edge of the second deflector plate 12. As can be seen from fig. 3, if two beveled lowest points of the second baffle 12 are connected (as shown by a dotted line), the top of the second baffle 12 is isosceles trapezoid, and the height of the isosceles trapezoid is 15-25 mm; if the height from the bottom of the high-density sedimentation tank to the top edge of the second deflector 12 is defined as the maximum height of the second deflector 12 and the height from the bottom of the high-density sedimentation tank to the lowest point of the second deflector 12 after beveling is defined as the minimum height of the second deflector, the heights of the first deflector 11 and the third deflector 13 do not exceed the first deflectorThe minimum height of the baffles 12.
Specifically, in the embodiment shown in fig. 3, the heights of the first baffle 11 and the third baffle 13 are equal to the minimum height of the second baffle 12. The structure can effectively split and concentrate the water flow rushing from the middle area, and the water distribution of the guide plug flow area 23 is more uniform.
Further, as shown in fig. 4, in a preferred embodiment of the present application, on the basis of the embodiment shown in fig. 3, the heights of the first baffle 11 and the third baffle 13 are reduced by 8-15 mm relative to the height of the second baffle 12, so that the liquid flow rate can be reduced by 2-4 times relative to the highest flow rate of the concentrated falling liquid in the middle area in the prior art, the water distribution of the plug-flow area 23 is more uniform, and the advantages of simple structure, convenience in industrial production, construction and improvement are achieved.
In the above embodiment, considering various factors such as the area of the clarification zone 30, the reduction of the liquid flow rate, the more uniform liquid flow rate, and the improvement of the sedimentation capacity, the inventors found that if the widths of the first baffle 11, the second baffle 12, and the third baffle 13 are L 1 、L 2 、L 3 When L 1 ＝L 3 ，L 2 ＝5L 1 ～15L 1 The effect is better when in use.
