DETAILED DESCRIPTION

[0040] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0041] The integrated pool for treating sewage according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0042] like Figures 1 to 5 As shown, the integrated tank 1 according to an embodiment of the present invention includes a primary sedimentation tank 10 , a first regulating tank 20 , a second regulating tank 30 and a water distribution assembly 40 .

[0043] A portion of the first regulating tank 20 is adjacent to the primary settling tank 10, and a common first tank wall 50 is provided between the two. A portion of the second regulating tank 30 is adjacent to the primary settling tank 10, and a common second tank wall 60 is provided between the two. The water distribution assembly 40 is connected to the first tank wall 50 and the second tank wall 60 and is located in the primary settling tank 10, so that the sewage in the primary settling tank 10 is distributed to the first regulating tank 20 and the second regulating tank 30 according to a predetermined flow rate.

[0044] According to the integrated tank 1 of the embodiment of the present invention, the primary sedimentation tank 10, the first regulating tank 20 and the second regulating tank 30 are constructed together, and the first regulating tank 20 and the second regulating tank 30 are respectively adjacent to the primary sedimentation tank 10, which not only has the functions of the primary sedimentation tank and the regulating tank, but also reduces the floor space compared to the separate construction of the primary sedimentation tank and the regulating tank. At the same time, in the integrated tank 1, the primary sedimentation tank 10 uses the water distribution component 40 to distribute sewage to the first regulating tank 20 and the second regulating tank 30 according to the predetermined flow rate, so that the first regulating tank 20 and the second regulating tank 30 can receive sewage of the predetermined flow rate to improve the regulation efficiency of the first regulating tank 20 and the second regulating tank 30.

[0045] It should be noted that the predetermined flow rate is based on the sewage demand of the first regulating tank 20 and the second regulating tank 30, and sewage is distributed to the first regulating tank 20 and the second regulating tank 30 at a certain flow rate. The predetermined flow rate of the first regulating tank 20 and the predetermined flow rate of the second regulating tank 30 may be different or the same.

[0046] like Figures 1 to 5 As shown, in order to make the technical solution of the present application easier to understand, the technical solution of the present application is described in more detail below with a specific implementation of the integrated tank 1. The integrated tank 1 according to an embodiment of the present invention includes a primary settling tank 10, a first regulating tank 20, a second regulating tank 30 and a water distribution assembly 40.

[0047] In some embodiments, a portion of the first regulating tank 20 is adjacent to the primary settling tank 10, and a common first tank wall 50 is provided between the two. A portion of the second regulating tank 30 is adjacent to the primary settling tank 10, and a common second tank wall 60 is provided between the two. The water distribution assembly 40 is connected to the first tank wall 50 and the second tank wall 60 and is located in the primary settling tank 10, so that the sewage in the primary settling tank 10 is distributed to the first regulating tank 20 and the second regulating tank 30 according to a predetermined flow rate.

[0048] Specifically, a portion of the first regulating tank 20 is adjacent to the primary settling tank 10, and a portion of the second regulating tank 30 is adjacent to the primary settling tank 10. The first regulating tank 20 and the second regulating tank 30 may be spaced apart from each other, and the two are connected via the primary settling tank 10. In addition, the first regulating tank 20 and the second regulating tank 30 may also be adjacent to each other, that is, the first regulating tank 20, the second regulating tank 30 and the primary settling tank 10 are adjacent to each other. In this regard, the first regulating tank 20 and the second regulating tank 30 are adjacent to each other or spaced apart from each other, and the first regulating tank 20, the second regulating tank 30 and the primary settling tank 10 are combined and constructed. Compared with the separate construction of the three, not only does the integrated tank 1 have the functions of the primary settling tank and the regulating tank at the same time, but also reduces the floor space occupied by the separate construction of the three.

[0049] At the same time, the primary sedimentation tank 10 can distribute a predetermined flow of sewage to the first regulating tank 20 and the second regulating tank 30 respectively through the water distribution component 40 to control the amount of sewage entering the first regulating tank 20 and the second regulating tank 30 respectively, so that the primary sedimentation tank 10 can participate in the sewage regulation process of the first regulating tank 20 and the second regulating tank 30 to improve the regulation efficiency of the first regulating tank 20 and the second regulating tank 30. That is to say, when the first regulating tank 20 or the second regulating tank 30 is in the process of regulating sewage, when the first regulating tank 20 or the second regulating tank 30 needs a large amount of sewage in a short time, more sewage can be distributed to the first regulating tank 20 or the second regulating tank 30 by controlling the water distribution component 40 to meet the sewage demand of the first regulating tank 20 or the second regulating tank 30. In addition, when the first regulating tank 20 does not need to take in water, all the sewage in the primary sedimentation tank 10 can be distributed to the second regulating tank 30 to avoid the sewage in the primary sedimentation tank 10 from being full, that is, the first regulating tank 20 and the second regulating tank 30 are in a standby relationship with each other. When the second regulating tank 30 does not need to be filled with water, the principle is the same as that of the first regulating tank 20 not needing to be filled with water, and will not be repeated here.

[0050] In some embodiments, the water distribution assembly 40 includes a water collection tank 41, a first valve 42, and a second valve 43. One end of the water collection tank 41 is connected to the first tank wall 50 and communicated with the first regulating tank 20, and the other end of the water collection tank 41 is connected to the second tank wall 60 and communicated with the second regulating tank 30. The first valve 42 is provided at the connection between the water collection tank 41 and the first regulating tank 20, so as to distribute the sewage in the primary settling tank 10 to the first regulating tank 20 according to a predetermined flow rate. The second valve 43 is provided at the connection between the water collection tank 41 and the second regulating tank 30, so as to distribute the sewage in the primary settling tank 10 to the second regulating tank 30 according to a predetermined flow rate.

[0051] Specifically, Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the water collection tank 41 in the primary sedimentation tank 10 can be used to collect sewage precipitated by the primary sedimentation tank 10. Then the sewage collected in the water collection tank 41 is distributed to the first regulating tank 20 and the second regulating tank 30 according to a predetermined flow rate through the first valve 42 and the second valve 43. Among them, the first valve 42 is installed at the connection between the water collection tank 41 and the first regulating tank 20, and can control the flow of sewage flowing from the water collection tank 41 into the first regulating tank 20, so as to achieve the distribution of sewage to the first regulating tank 20 according to the predetermined flow rate. At the same time, the function and principle of the second valve 43 are similar to those of the first valve 42, and will not be repeated here.

[0052] The first valve 42 and the second valve 43 in the present invention can be long-rod knife gate valves, which can be turned on and off by rotating the long rod to operate the valve opening to control the amount of sewage entering the first valve 42 and the second valve 43.

[0053] In addition, the water distribution assembly 40 in the present invention is far away from the sewage inlet 11 of the primary sedimentation tank 10. In other words, the water collection tank 41 is far away from the sewage inlet 11 of the primary sedimentation tank 10. When the water collection tank 41 is farther away from the sewage inlet 11 of the primary sedimentation tank 10, that is, the distance from the sewage just entering the primary sedimentation tank 10 to flowing into the water collection tank 41 is farther, the sewage is more fully precipitated in the primary sedimentation tank 10.

[0054] In some embodiments, the integrated pool 1 includes a slag retaining plate 70, which is located in the primary sedimentation tank 10 and adjacent to the water inlet side 411 of the sump 41, and the slag retaining plate 70 and the sump 41 are spaced apart from each other, wherein the slag retaining plate 70 extends along the length direction of the sump 41 to the first pool wall 50 and the second pool wall 60, and the upper edge of the slag retaining plate 70 is higher than the water inlet edge 4111 of the water inlet side 411, and the lower edge of the slag retaining plate 70 is lower than the water inlet edge 4111.

[0055] Specifically, Figures 1 to 4 As shown, one end of the slag retaining plate 70 is installed on the first pool wall 50, and the other end of the slag retaining plate 70 is installed on the second pool wall 60, and is located in the primary sedimentation tank 10 and adjacent to the water inlet side 411 of the sump 41, so as to prevent the scum in the primary sedimentation tank 10 from crossing the water inlet side 411 and entering the sump 41, thereby preventing the scum from blocking the connection between the sump 41 and the first regulating tank 20 and the second regulating tank 30.

[0056] In addition, if Figures 1 to 4 As shown, one of the two sides of the water collecting tank 41 is the water inlet side 411, or the two sides of the water collecting tank 41 are the water inlet sides 411. When the two sides of the water collecting tank 41 are the water inlet sides 411, slag retaining plates 70 are installed at intervals on both sides of the water collecting tank 41 to retain the scum in the primary sedimentation tank 10.

[0057] In some embodiments, the integrated pool 1 includes a weir plate 80, which is arranged on the water inlet side 411, and the weir plate 80 extends along the length direction of the sump 41 to the first pool wall 50 and the second pool wall 60, and the overflow water level of the weir plate 80 is lower than the upper edge of the slag retaining plate 70.

[0058] Specifically, Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the weir plate 80 is installed on the water inlet side 411 of the water collecting tank 41, which can not only regulate the water volume, but also prevent the scum from entering the water collecting tank 41. In addition, the weir plate 80 and the scum blocking plate 70 can further prevent the scum from being blocked under the coordinated action. Among them, the weir plate 80 in the present invention is a triangular weir.

[0059] In some instances, the integrated pool 1 further includes a flushing pipe 120 , which is disposed on the upper edge of the weir plate 80 and extends along the length direction of the sump 41 . The flushing pipe 120 is provided with an overflow port toward the weir plate 80 and flushing ports arranged sequentially along the length direction of the sump 41 .

[0060] Specifically, Figure 5 As shown, the flushing pipe 120 is installed on the upper edge of the weir plate 80, and the flushing pipe 120 can flush the sludge in the overflow port of the weir plate 80 through the flushing port, thereby preventing the overflow port of the weir plate 80 from being blocked by accumulated sludge, thereby ensuring the normal operation of the weir plate 80.

[0061] In some embodiments, the integrated pool 1 further includes a mud suction assembly 90, which includes a first mud suction pipe 91 and a second mud suction pipe 92. A portion of the first mud suction pipe 91 is arranged in the primary sedimentation tank 10, one end of the first mud suction pipe 91 is spaced from the inner wall surface of the primary sedimentation tank 10 and is connected to the primary sedimentation tank 10, and one end of the first mud suction pipe 91 is spaced from the bottom of the primary sedimentation tank 10. A portion of the second mud suction pipe 92 is arranged in the primary sedimentation tank 10, one end of the second mud suction pipe 92 is spaced from the inner wall surface of the primary sedimentation tank 10 and is connected to the primary sedimentation tank 10, and one end of the second mud suction pipe 92 is located at the bottom of the primary sedimentation tank 10.

[0062] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the sludge suction port of the first sludge suction pipe 91 is spaced apart from the inner wall surface of the primary sedimentation tank 10 and is spaced apart from the bottom of the primary sedimentation tank 10. In other words, the first sludge suction pipe 91 is used to absorb the sludge located in the middle of the primary sedimentation tank 10. That is, the sludge suction port of the first sludge suction pipe 91 is located at the center of the horizontal cross-section of the primary sedimentation tank 10, and the sludge suction port of the first sludge suction pipe 91 is spaced apart from the bottom of the primary sedimentation tank 10. The sludge suction port of the second sludge suction pipe 92 is spaced apart from the inner wall surface of the primary sedimentation tank 10 and is located at the bottom of the primary sedimentation tank 10. In other words, the second sludge suction pipe 92 is used to absorb the sludge at the bottom of the primary sedimentation tank 10. When the primary sedimentation tank 10 actually absorbs sludge, the sludge suction assembly 90 is not always in working condition. When the sludge in the primary sedimentation tank 10 accumulates to a certain extent, the sludge suction assembly 90 is started to absorb the sludge in the primary sedimentation tank 10. Sometimes, the sludge in the primary sedimentation tank 10 accumulates a lot over a period of time, making the viscosity of the sludge at the bottom of the primary sedimentation tank 10 too high, which causes the second sludge suction pipe 92 to absorb the sludge unsmoothly, and is more likely to cause the second sludge suction pipe 92 to be blocked. In the present invention, the first sludge suction pipe 91 can absorb the sludge above the bottom of the tank, reduce the accumulation of sludge, and thus reduce the viscosity of the sludge at the bottom of the primary sedimentation tank 10, ensuring that the second sludge suction pipe 92 can smoothly absorb the sludge at the bottom of the primary sedimentation tank 10.

[0063] In the present invention, the sludge suction assembly 90 also includes a sludge suction pump 93, which mainly provides power for the first sludge suction pipe 91 and the second sludge suction pipe 92. The sludge suction pumps 93 can be installed in parallel in a form of multiple units to ensure that the sludge suction assembly 90 efficiently absorbs the sludge in the primary sedimentation tank 10. The multiple parallel sludge suction pumps 93 serve as backup for each other, which can ensure the continuous operation of the sludge suction assembly 90. That is, when some of the sludge suction pumps 93 are damaged, the other sludge suction pumps 93 can also operate normally to ensure the sludge suction progress of the sludge suction assembly 90.

[0064] In some embodiments, the integrated pool 1 further includes a drainage assembly 100, which includes a first variable frequency pump body 101, a second variable frequency pump body 102, a downstream system pipe 103 and a regulating pipe 104. The liquid inlet of the first variable frequency pump body 101 is respectively connected to the first regulating pool 20 and the second regulating pool 30. The liquid inlet of the second variable frequency pump body 102 is respectively connected to the first regulating pool 20 and the second regulating pool 30. The water inlet of the downstream system pipeline 103 is respectively connected to the water outlet of the first variable frequency pump body 101 and the water outlet of the second variable frequency pump body 102. One end of the regulating pipe 104 is connected to the downstream system pipe 103, and the other end of the regulating pipe 104 is connected to the primary sedimentation tank 10.

[0065] Specifically, Figure 1 and Figure 2As shown, after the sewage is regulated by the first regulating tank 20 and the second regulating tank 30, the sewage of the first regulating tank 20 and the second regulating tank 30 is discharged into the next system by the drainage component 100, so as to perform subsequent treatment on the sewage. Among them, the water outlet of the first variable frequency pump body 101 and the water outlet of the second variable frequency pump body 102 are simultaneously connected to the downstream system pipe 103, and the first variable frequency pump body 101 and the second variable frequency pump body 102 can adjust the water output of the first regulating tank 20 and the second regulating tank 30 respectively. In other words, the first variable frequency pump body 101 and the second variable frequency pump body 102 work separately, and one of the first variable frequency pump body 101 and the second variable frequency pump body 102 fails or is repaired, and the other of the first variable frequency pump body 101 and the second variable frequency pump body 102 can still work normally. In addition, one end of the regulating pipe 104 is connected to the downstream system pipe 103, and the other end of the regulating pipe 104 is connected to the primary sedimentation tank 10. When the pressure in the downstream system pipe 103 is too high, the regulating pipe 104 can discharge a portion of the liquid into the primary sedimentation tank 10 to relieve the pressure in the upstream system pipe 103 and can also regulate the flow in the downstream system pipe 103 .

[0066] In some embodiments, the integrated pool 1 also includes a retaining wall 110, which is arranged in the primary sedimentation tank 10. The integrated pool 1 has a sewage inlet 11, which is connected to the primary sedimentation tank 10. The retaining wall 110 is arranged adjacent to the sewage inlet 11 to slow down the flow rate of the sewage.

[0067] Specifically, Figures 1 to 3 As shown, the water retaining 110 is mainly used to slow down the flow rate of sewage entering the primary settling tank 10. That is, the flow rate of sewage entering the primary settling tank 10 is too high, and the sewage flows into the sump 41 in a very short time, causing the pollutants in the sewage to enter the first regulating tank 20 and the second regulating tank 30 without sufficient precipitation.

[0068] In some embodiments, a first overflow port 51 connected to the primary settling tank 10 and the first regulating tank 20 is provided on the first pool wall 50, and a second overflow port 61 connected to the primary settling tank 10 and the second regulating tank 30 is provided on the second pool wall 60, wherein the first overflow port 51 and the second overflow port 61 are located at the same height, and the heights of both are higher than the height of the water distribution assembly 40.

[0069] Specifically, Figures 1 to 3 As shown, when there is too much sewage in the primary sedimentation tank 10, the first overflow port 51 and the second overflow port 61 can discharge the sewage in the primary sedimentation tank 10 into the first regulating tank 20 and the second regulating tank 30 in time, avoiding leakage of sewage in the primary sedimentation tank 10 and preventing the sewage in the primary sedimentation tank 10 from contaminating the water in the subsequent system.

[0070] A sewage treatment system according to an embodiment of the present invention includes the above-mentioned integrated pool.

[0071] In the sewage treatment system, the primary sedimentation tank 10, the first regulating tank 20 and the second regulating tank 30 are constructed together, which reduces the floor space compared to the separate construction of the primary sedimentation tank and the regulating tank. In addition, the water distribution component 40 can be used to efficiently control the water inflow into the first regulating tank 20 and the second regulating tank 30 to ensure the efficient operation of the sewage treatment system. Finally, during the process of the sludge suction component 90 discharging sludge from the primary sedimentation tank 10, the sludge suction component 90 can avoid blockage and efficiently discharge sludge from the primary sedimentation tank 10.
