Description
Technical Field
The invention relates to the technical field of sewage treatment, in particular to a high-density sedimentation tank.
Background
In recent years, as domestic sewage, garbage and industrial wastewater are discharged in large quantities, the treatment work of water pollution is more intensive. People pay more attention to the quality of water in the process of using water resources. Therefore, when water treatment is performed, a high-density sedimentation tank is often used. The high-density sedimentation tank has the advantages of sedimentation and coagulation, small floor 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 large differences in the aspects of tank type arrangement, operation parameters and the like, and has high requirements on operation management. And due to lack of design standard, the due effect is difficult to be exerted in practical use.
Disclosure of Invention
The application provides a high density sedimentation tank, including reaction zone and clarification zone. Wherein, the reaction area is divided into a mixing area and a thrust area by a guide wall; the thrust zone is enclosed by a guide wall and a plurality of baffle plates; the baffle plate extends upwards from the bottom of the high-density sedimentation tank, faces different directions and can divide water flow into at least three flow directions; and the height of the baffle plate is gradually reduced along with the approach of 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, liquid in the thrust zone can only fall down along one wall body and flow into the clarification zone, so that the liquid in the middle area of the wall is poured intensively, the flow velocity is high, and turbulent flow is caused; while the area near the wall edge has less liquid distribution and relatively low flow rate. The sewage cannot be completely settled due to overlarge flow speed and uneven water flow distribution, and the quality of sewage treatment is affected. Compared with the prior art, in the technical scheme provided by the application, the flow pushing area is defined by the guide wall and the plurality of baffle plates facing to different directions, liquid can fall along the surface where each baffle plate is located, the flow path of the liquid is increased under the condition of equal flow, and the flow speed of the liquid is reduced; on the other hand, the inventor finds that the height of the baffle plates is set to be gradually reduced along with the approach of the guide wall, so that the water distribution in the plug flow area can be more uniform, namely, the flow velocity of sewage falling along each baffle plate can be more even. The term "gradual height decrease" as used herein may refer to a decrease in gradient, a gradual or ramp decrease, or a combination thereof. These improvements all promote more complete liquid settling to improve the quality of sewage treatment. In addition, the baffle plate occupies less space than a wall body, is flexible to install, can be adjusted according to production requirements, can integrally improve the occupied area utilization rate of the high-density sedimentation tank and reduce the construction cost.
Specifically, in one embodiment, the flow pushing area comprises a first baffle plate, a second baffle plate and a third baffle plate which are connected in sequence; the second baffle is parallel to the guide wall, the first baffle and the third baffle are equal in height, and the heights of the first baffle and the third baffle are 8-15 millimeters (mm) lower than that of the second baffle. That is to say, in this technical scheme, the height of the second baffler that is the farthest away from the guiding wall is the highest, and the first baffler that is connected with the guiding wall and the height of third baffler are slightly lower than the second baffler, and this structure can effectively shunt the water current of concentrating from the regional washing of middle part, and the guide pushes away the district water distribution more evenly.
In another embodiment, the plug flow region comprises a first baffle plate, a second baffle plate and a third baffle plate connected in series. Wherein, the second baffle is parallel with the guide wall, and the width of the second baffle is L2The second baffle is configured to: the distance between the top of the second baffle plate and the edge is 0.2L2～0.4L2The position of the baffle is obliquely cut downwards by 15-25 mm towards the edge of the second baffle plate. That is, if the two obliquely cut lowest points of the second baffle plate are connected, the top of the second baffle plate is an 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 plate is defined as the maximum height of the second baffle plate, and the height from the bottom of the high-density sedimentation tank to the obliquely cut lowest point of the second baffle plate is defined as the minimum height of the second baffle plate, the heights of the first baffle plate and the third baffle plate are not more than the minimum height of the second baffle plate.
Further, the inventor finds that if the heights of the first baffle plate and the third baffle plate are reduced by 8-15 mm relative to the minimum height of the second baffle plate on the basis of the above embodiment, the flow speed of the liquid can be reduced by 2-4 times relative to the highest flow speed of the liquid falling in the central area in the prior art, and the water distribution in the plug flow area is more uniform. That is to say, the small change of the height of the baffle plate is great to improve the turbulence phenomenon of the high-density sedimentation tank, and the technical scheme also has the advantages of simple structure, and convenience for industrial production, construction and improvement.
In the above embodiment, the first baffle, the second baffle, and the third baffle each have a width L1、L2、L3Wherein L is1＝L3，L2＝5L1～15L1. Because the technical scheme does not adopt a wall body with two blocked ends in the prior art, the area of a clarification area and the effects and the settling capacity of reducing the liquid flow rate and enabling the liquid flow rate to be more uniform need to be comprehensively considered, the thrust flow area of the structure is designed.
In the above embodiment, the second baffle has a height of 2.7 to 3.8 meters (m).
Further, the mixing area comprises a reaction tank, sewage can enter the mixing area from the bottom of the reaction tank after entering the high-density sedimentation tank, the sewage treated by the reaction tank flows out of the top of the reaction tank and flows downwards along the guide wall, and then the sewage can flow to the plug flow area from the lower part of the guide wall.
Further, the clarification zone comprises a concentration zone, a water distribution zone and an inclined tube zone; wherein, the sewage entering 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 downwards deposited to the concentration area and can be discharged out of the high-density sedimentation tank from the bottom of the concentration area; and liquid in the water distribution area is accumulated upwards to the inclined tube area, and is filtered by the inclined tube area to obtain outlet 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 present application provides a high density settling tank comprising a reaction zone 20 and a clarification zone 30, the reaction zone 20 being divided by a dividing wall 22 into a mixing zone 21 and a plug flow zone 23.
In one embodiment of the present application, the mixing zone 21 includes a reaction tank 211, the sewage can enter the mixing zone 21 from the bottom of the reaction tank 211 after entering the high-density sedimentation tank, the sewage treated by the reaction tank 211 flows out from the top of the reaction tank 211 and flows down along a guide wall 22, and the guide wall 22 is spaced from the bottom of the high-density sedimentation tank to allow the liquid to flow into the thrust zone 23.
In one embodiment of the present application, the clarification zone 30 comprises a water distribution zone 32, a concentration zone 31, and a chute zone 33. The sewage entering the clarification zone 30 through the thrust 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 out of the high-density sedimentation tank from the bottom of the concentration zone 31; as shown in fig. 1, the concentration zone 31 is provided with a mud scraper 311. As the liquid level of the water distribution area 32 is increased continuously and accumulated to the inclined pipe area 33, the liquid is filtered by the inclined pipe 331 of the inclined pipe area 33 to obtain clear outlet 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 guide wall 22 and the plurality of baffle plates 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, faces different directions and can divide water flow into at least three flow directions; and the height of the baffle 10 is gradually reduced as it approaches the guide wall 22. The sewage treated by the reaction zone 20 flows into the clarification zone 30 from the top of the plug flow zone 23.
The structure increases the liquid flow path under the condition of equal flow, and reduces the flow speed of the liquid; the height of the baffle plate 10 is set to be gradually reduced along with the approach of the guide wall 22, so that the water distribution of the plug flow area 23 is more uniform. These improvements all promote more complete liquid settling to improve the quality of sewage treatment. In addition, the baffle plate 10 occupies less space than a wall body, is flexible to install, can be adjusted according to production requirements, can integrally improve the occupied area 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 connected in series; 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 height of the first baffle plate 11 and the height of the third baffle plate 13 are 8-15 mm lower than that of the second baffle plate 12. As can be seen from fig. 2, the height of the second baffle 12 farthest from the guide wall is the highest, and the heights of the first baffle 11 and the third baffle 13 connected to the guide wall 22 are slightly lower than that of the second baffle 12, which can effectively divide and concentrate the water flowing down from the central area, and guide the water distribution in the thrust area 23 to be more uniform.
Fig. 3 shows another embodiment of the present application, and likewise, the flow pushing area 23 includes a first baffle plate 11, a second baffle plate 12 and a third baffle plate 13 connected in sequence, wherein the second baffle plate 12 is parallel to the guide wall 22, and the width of the second baffle plate is L2. In contrast, the second baffle plate 12 is configured to: the distance between the top of the second baffle plate 12 and the left and right edges is 0.2L2～0.4L2The position of the baffle is obliquely cut downwards by 15-25 mm towards the edge of the second baffle plate 12. As shown in FIG. 3, if the two chamfered lowest points of the second baffle 12 are connected (e.g. dotted line)Shown by a line), the top of the second baffle 12 is an isosceles trapezoid, and the height of the isosceles trapezoid is 15-25 mm; if the height from the bottom of the high-density settling tank to the top edge of the second baffle plate 12 is defined as the maximum height of the second baffle plate 12, and the height from the bottom of the high-density settling tank to the lowest point of the second baffle plate 12 after beveling is defined as the minimum height of the second baffle plate, the heights of the first baffle plate 11 and the third baffle plate 13 do not exceed the minimum height of the second baffle plate 12.
Specifically, in the embodiment shown in fig. 3, the height of each of the first and third baffle plates 11 and 13 is equal to the minimum height of the second baffle plate 12. The structure can also effectively divide and concentrate the water flow rushed down from the middle area, and the water distribution of the guide thrust 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 to 15mm relative to the height of the second baffle 12, which reduces the liquid flow rate by 2 to 4 times relative to the highest flow rate of the liquid falling intensively in the middle area in the prior art, and the thrust area 23 distributes water more uniformly.
In the above embodiment, considering a plurality of 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 settling capacity, the inventors found that if the widths of the first baffle plate 11, the second baffle plate 12, and the third baffle plate 13 are L1、L2、L3When L is present1＝L3，L2＝5L1～15L1The effect is better.
